Knowledge byte-identical (fact 134, thought 23, + source 8, datasource 7, keyword 603, activity_log 1199 — unchanged). + +Re-created "Dimitris Madenidis" via the corrected flow (logs confirm the +verbatim non-anchored template, no leakage).

Consistency ✓. + +Conclusion: conflation was a **process** failure, now fixed with prompt + +safe reset only — no new code, gates, or bloat. Caveats: verified on the +Madenidis case in create mode; the ~700 triage backlog still to be drained, +and per-wiki runs are slow (recall + a real resolution subagent on +gemma-4-31B → minutes each → this is background-scheduler work, not +interactive). Upstream fact-level identity anchoring remains a *possible +future enhancement*, but is **not required** to get correct pages. + +## What this is + +A wiki layer inside BrainDB. Wikis are synthesised, human-readable pages +(`entity_type = 'wiki'`) about one concept each, built from the +keyword/thought/fact entities that concern it — Karpathy-style, but stored as +entities (not files) and kept consistent with the graph. + +Three-stage pipeline: + +1. **Cron** (`POST /api/v1/wiki/cron`) — read-only orphan scan; enqueues one + `triage` job per entity not yet connected to a wiki. Idempotent. +2. **Maintainer** (`POST /api/v1/wiki/maintain`) — processes **exactly one** + triage case per call (C1); the existing agent decides + attach / create / consolidate / skip and a structured suggestion job is + persisted. +3. **Writer** (`POST /api/v1/wiki/write`) — one wiki per call. The agent + authors the body + a change manifest; a deterministic **accounted-change + gate** validates it; the references ledger and `summarises` relations are + reconciled from the body+manifest; the prior revision is snapshotted. + +Inspection: `GET /api/v1/wiki/jobs`. Always-on driving (Stage 2): the +`wiki_scheduler` sidecar, **opt-in** via the `wiki` compose profile. + +## Governing constraints + +- **C1 — per-case maintainer.** Never a bulk dump; one orphan per invocation. +- **C2 — no programmatic destruction without LLM awareness.** Deterministic + code is limited to read-only detection, safe queue plumbing, and additive + bookkeeping that mirrors LLM-authored content / executes the LLM's explicit + manifest. Every consequential change is logged and reversible. +- **C3 — reuse existing APIs; no bloat.** Detection/ranking/contradiction + context all go through the existing `recall_memory` / `/memory/context` + scoring. No new similarity query, scoring heuristic, or embedding path. + +## Writer robustness (the accounted-change model) + +Surgical add/modify/**delete** is allowed; *undeclared* or *accidental* loss +is impossible.

The wikis are +structurally perfect and provenance-consistent but **not evidence-grounded**. +Scaling now would mass-produce fluent-but-hollow pages citing tokens. + +Root cause is *not* pipeline code (which works).

If that recall surfaces an existing wiki very close to the case's concept, the maintainer emits a `consolidate` suggestion. The **wiki-writer LLM performs the merge** via existing tools, logged, reversible — no `merge_wikis()` SQL, no bespoke cosine query. `not_duplicate`/`duplicate_of` are plain relations the LLM sees via existing relation/graph tools and is prompted to respect (self-clearing without a custom SQL filter). | +| D6 | Summary / disambiguation / language | Reuse `entities.summary` for the cheap one-line header; `wikis_ext.disambiguation` + `wikis_ext.language` (mirrors `datasources_ext.language`). | +| D7 | Driver | In-house agent first (new prompts + reuse `/agent/query`).

For `current - cited` *not* in the manifest, that is an undeclared drop → already rejected by the gate (this branch should never persist).

An undeclared drop or add ⇒ violation (this is what blocks *accidental* destruction while *allowing* declared deletion). +4. **Section guard** (`attach` only): non-targeted sections hash-identical; a change outside `manifest.modified_sections` ⇒ violation. +5. **Structural validation**: required anchors present; `summary` ≤ 280 chars; `disambiguation` non-empty; every surviving `[[ref:UUID]]` resolves in `entities`. +6. **Provenance is preserved, not erased.** A declared removal does **not** silently delete the entity or just drop the `summarises` edge into the void. The writer must, via existing tools, either (a) replace `summarises` with a typed relation that records the judgement — `contradicts` (this member opposes the consensus), `challenges`, or keep a low-relevance historical `summarises` — or (b) raise a fix-up `triage` job if the source entity itself looks wrong. The writer never deletes *other* entities; it only re-types its own link and explains why. `removed_refs[].prior_text` + reason are written to the wiki `notes` / activity log. +7. Any violation ⇒ **rollback**, job → `pending` with `last_error`, retry with the explicit defect ("undeclared drop of X", "section Z changed but not in manifest", "summary too long").

Never a silent bad write. + +### Contradiction handling (the writer must reason about opposition) + +Before editing, the writer is **required** to gather opposition context using the +**existing infra** (C3): `recall_memory` / `view_tree` / `view_entity_relations` +over the member entities surface any `contradicts`/`challenges` relations and +semantically opposed claims (the existing scoring already clusters them).

The gate cross-checks: a UUID that vanished and was part of a +detected contradiction must appear in `contradictions_resolved`. + +### Reversibility (deleted ≠ destroyed) + +Every writer save first snapshots the prior `content` + parsed refs into the activity +log (`operation='wiki_revise'`, with `revision` n→n+1) before mutation. So any +removal — even a correct one — is auditable and restorable from the log. "Edited a +specific part / removed something that doesn't make sense" is fully supported; +"content vanished with no record or reason" is structurally impossible. + +This makes "surgical edits yes, destruction no" a checked invariant, not a hope — +true regardless of which LLM profile is active. + +### Style robustness levers (in `wiki_writer_prompt.md`) + +- The skeleton above is the mandatory output contract (sections, order, anchors, ref syntax, tone: encyclopedic, third-person, dated, contradictions flagged with both refs, every non-trivial claim carries a `[[ref:]]`). +- A **golden template** for `create` so structure is identical across all wikis from day one. +- A **few-shot exemplar**: one well-formed wiki + a before/after `attach` showing existing content preserved and the new member integrated. +- Deliberately **small focused context** (one wiki's body + only that wiki's new members) — the maintainer being per-case keeps the writer's input bounded; focused context is itself a major robustness lever. + +--- + +## Pipeline mechanics + +**Cron** (`POST /api/v1/wiki/cron`, pure SQL, read-only + safe enqueue, no LLM): +select keyword/thought/fact entities with no `summarises`/member link to any wiki and +not already in an active job; for **each** orphan insert one `triage` `wiki_job` +(`dedupe_key = triage:`, `ON CONFLICT DO NOTHING`).

Draining the backlog now costs ~one maintainer call per real concept, not per entity. - wiki_scheduler is now a normal always-on sidecar (removed the opt-in compose profile) — same posture as the ingest watcher; zero manual steps to operate. Cron cadence relaxed to ~20m so ingestion has time to settle (no in-flight detection logic — just a longer interval). - Docs reframed: two hands-off sidecars (ingest + wiki); the manual /api/v1/wiki/* endpoints are debug-only, not the operating procedure. - Add a local-vLLM provider profile (workstation, port 8010). No new endpoint/table/dependency/gate; inspection/export stays an optional read-only dev tool outside the operating path. --- README.md | 31 ++++++++++- braindb/config.py | 5 ++ braindb/routers/wiki.py | 18 +++++-- braindb/services/wiki_jobs.py | 99 +++++++++++++++++++++++------------ braindb/wiki_scheduler.py | 2 +- docker-compose.yml | 11 ++-- docs/maintainer-agent-plan.md | 10 ++++ 7 files changed, 129 insertions(+), 47 deletions(-) diff --git a/README.md b/README.md index 79854dc..cdcec91 100644 --- a/README.md +++ b/README.md @@ -33,7 +33,7 @@ Relations connect any two entities with `relation_type`, `relevance_score`, `imp ## Setup -BrainDB runs as two Docker services — `api` and `watcher` — against an **external** PostgreSQL you provide.

Consolidate (consolidate_wiki_ids) and the writer survivor (canonical_id) had the identical latent bug. Harness now injects a NUMBERED catalog of active wikis at the END of the maintainer prompt (dynamic-last; static prefix stays cache-stable). The LLM still decides which/whether by recognition; it returns small integers (target_wiki_no / consolidate_nos), and the harness maps number->id deterministically from the in-request list (orchestration, not decision). Same mechanism applied to the writer: numbered duplicates list -> canonical_no. A number not in the list is rejected, so a hallucinated id is impossible.

Only the scheduler awaited each HTTP call before the next. Replace the sequential block with a stdlib ThreadPoolExecutor fan-out: one /wiki/maintain in flight (C1 preserved) runs CONCURRENTLY with up to WRITE_PARALLELISM (default 3) /wiki/write calls per batch; drains in batches until empty or DRAIN_MAX. Threads block on HTTP (GIL released on socket I/O) -> real I/O parallelism; uvicorn handles concurrent endpoints; vLLM batches the inferences on the GPU. Safety is already in place: SKIP LOCKED guarantees different rows per claim; try_wiki_lock makes same-wiki writers skip gracefully (written:0, 'target locked'); stale-lease covers any abandoned assigned.

That flag also makes the SDK pass response_format: json_schema on EVERY LLM turn (not just the final one), so weaker models satisfy the schema immediately on turn 1 and never call any tool. Symptom: Selonda query -> 3.4 s, one LiteLLM call, zero TOOL log lines, model confabulated or skipped. This restores intermediate-turn freedom WITHOUT giving up 30a54e5's real win (strict @function_tool argument schema on each submit_result, so the typed final cannot be malformed). Mechanism: 1. Build agents without output_type. The LLM is free on every turn. 2. Each submit_* tool body parks its SDK-validated payload into a mutable slot stored in a ContextVar (braindb/agent/run_state.py). A mutable container is required because the SDK runs tool bodies in sub-Tasks whose ContextVar.set() does NOT propagate up; mutating a shared object inside the var does propagate (every Task sees the same reference). 3. run_typed installs a fresh slot per run (token-based set/reset so nested runs - parent -> delegate_to_subagent -> subagent - each get their own), awaits Runner.run, then returns slot.value. If empty it raises RuntimeError so callers surface "model never submitted" instead of silently returning bad data. 4. Routers receive the typed Pydantic instance directly. No model_validate_json, no try/except parse fallback. 5. System prompt: turn the soft submit_result line into an absolute mandate (every assistant message must be a tool call; the final one must be submit_result; prose is invalid). Strict everywhere, no per-agent special case. Verified live (deepinfra/Gemma-4-31B): /api/v1/agent/query for "What do you know about Selonda?" -> 14.5 s, three TOOL calls (recall_memory x2 + get_entity reading the full Selonda Aquaculture wiki) followed by TOOL submit_result with a grounded answer about Selonda Aquaculture, Saronikos Gulf operations, and the user's 2007-2010 manager role. Weaker models that still emit prose-terminal instead of submit_result now correctly surface a RuntimeError (500 / lease release) - not a silent fallback. That is the strict-across-the-board contract: the typed Pydantic final answer is by construction, or the run fails. --- braindb/agent/agent.py | 95 ++++++++++++++++++-------- braindb/agent/prompts/system_prompt.md | 4 +- braindb/agent/run_state.py | 72 +++++++++++++++++++ braindb/agent/tools.py | 62 ++++++++++------- braindb/routers/wiki.py | 26 ++++--- 5 files changed, 192 insertions(+), 67 deletions(-) create mode 100644 braindb/agent/run_state.py diff --git a/braindb/agent/agent.py b/braindb/agent/agent.py index f6b7535..666361d 100644 --- a/braindb/agent/agent.py +++ b/braindb/agent/agent.py @@ -5,21 +5,29 @@ trick, and that tool's argument is ALWAYS a typed Pydantic model.

Recall has been effectively running on the fuzzy/ full-text path alone for as long as this code shipped. Root cause ---------- braindb/services/keyword_service.py::find_entities_for_keywords did: SELECT e.*, array_agg(r.to_entity_id) AS matched_keyword_ids ... psycopg2 does not register a default uuid[] adapter, so the column came back as a literal Postgres array string ('{uuid1,uuid2,...}') rather than a Python list of UUIDs. The caller in context.py then did: matched_ids = [str(mid) for mid in (ent.get("matched_keyword_ids") or [])] which iterates the STRING character-by-character — yielding ['{', '5', 'c', 'a', 'f', 'a', ...]. Every subsequent kw_sim.get(mid, 0) returned 0, so best_sim = max(0, 0, 0, ...) = 0 for every entity. The merge step then either dropped them or weighted them via missing_signal_penalty against zero, which means the embedding signal contributed nothing. Diagnostic evidence: with the bug present, the Petros fact entered embedding_scores with score 0.000 (and the entire top-5 of the embedding pool was 0.000). After the fix, the same trace shows Petros at 0.902 and the top of the pool at 0.913 — real numbers. Verified live with the running deepinfra/Gemma-4-31B profile. The pattern is already used correctly in braindb/services/context.py::EXT_QUERIES for wikis_ext.member_keyword_ids ("::text[]"); find_entities_for_keywords was just missing the same cast. Fix --- braindb/services/keyword_service.py: cast array_agg explicitly to text via "array_agg(r.to_entity_id::text)" so psycopg2 returns a proper Python list of UUID strings, matching what kw_sim's keys already use. ~1 line of SQL plus a comment block citing the prior pattern. Scoring-pool widening (orthogonal, same theme) ---------------------------------------------- Once the embedding path actually scores, the SECOND issue is that the candidate pool itself was hard-capped at very low limits that the user considered (correctly) a budget-confusion: scoring is cheap pure-SQL/ vector work and should be wide; only the LLM-visible OUTPUT needs to be narrow (req.max_results, already correctly applied at sort+truncate). The old caps were treating a cheap stage like an LLM-cost stage. braindb/config.py: add two settings (defaults 500 each) - scoring_pool_keyword_neighbors: top-K keyword embeddings considered - scoring_pool_fuzzy: top-K fuzzy/fulltext candidates braindb/services/context.py: use those settings instead of the prior hard-coded 30 (for find_similar_keywords) and max(req.max_results, 20) (for fuzzy_search). A narrow single-word keyword whose embedding sits in a "name-cluster" (e.g. "Petros" clusters with "Dimitris", "Dimitrios- Koutsoumpos", etc.) can rank > 30 even when it's the exact term in the query; pulling 500 ensures it still reaches the scoring pool. Pure-SQL/ vector work, runs in milliseconds even at 500. LLM-cost invariant: the final items[: req.max_results] truncation in assemble_context is unchanged. The LLM still sees only the caller's chosen number of top-ranked items (typically 15-30). The scoring pool width affects WHICH candidates compete; the output width is the same. Also: clearer run_typed failure message --------------------------------------- braindb/agent/agent.py: when Runner.run terminates without a submit_* tool firing, the prior error message said "Likely max_turns exhausted". That is misleading — the SDK raises MaxTurnsExceeded separately, so by the time we get to the strict-mode RuntimeError it is almost always that the model emitted plain prose on its final turn (no tool call, SDK terminates naturally). Updated the message to say so, and added a short note explaining the two real causes for future debuggers. Verification ------------ 1. Live narrow-query trace for "Petros person identity profile": - Before fix: Petros embedding_score = 0.000 (entire embedding pool zero) - After fix: Petros embedding_score = 0.902 (top of pool at 0.913) 2. /api/v1/agent/query "What do you know about Dimitrios Koutsoumpos?" on deepinfra: 17.7 s, 893 chars, clean recall_memory -> submit_result sequence, structured grounded answer. Regression: pass. 3. Top-N final ranks for the Petros query rose from ~0.27 max to ~0.41 max as the embedding signal now contributes real numbers across entities that have matching keyword neighbours. Caveat (out of scope for this commit; documented for follow-up) --------------------------------------------------------------- The Petros fact itself still does not surface in the top 20 for narrow queries. Trace shows text_score = 0.06 (pg_trgm dilutes when a short query is compared against a much longer body), embedding_score = 0.90, and the geometric mean sqrt(0.06 * 0.90) = 0.23 drags the final rank below the wikis. The embedding-zero bug fix is the prerequisite for addressing this; the geometric-mean / text-dilution interaction is a separate scoring decision the user explicitly asked to leave alone for now ("Do NOT touch missing_signal_penalty or the geometric-mean merge").

Two new things land here, plus one prompt nudge. ## A.6 — fuzzy now goes through keywords too (symmetric retrieval) Before: the embedding pathway in assemble_context was keyword-mediated (after d4b9288), but the fuzzy pathway still ran pg_trgm + fulltext directly against entity content / title via fuzzy_search. The result was structurally unfair: a fact saved with keywords ["Petros", ...] got text_score ~0.06 against a multi-word query like "Petros person identity profile" because pg_trgm dilutes when a short query is compared against a long entity body. The keyword indexing was being bypassed by half the recall pipeline. After: a new helper find_fuzzy_keywords runs pg_trgm similarity(content, query) over entity_type='keyword' rows (short keyword content → no dilution), and assemble_context's text pathway fans out via the existing find_entities_for_keywords. Both pathways now produce a per-entity score equal to the best matched-keyword similarity over that entity's tagged_with neighbours. The geometric-mean merge and missing_signal_penalty are unchanged but become meaningful: they combine two signals about the SAME thing (how well the query matches this entity's keywords), one via trigrams and one via embeddings. fuzzy_search itself is intentionally left alone — it still serves the "arbitrary content matching" use-cases (quick_search agent tool, /memory/search). A discoverability backup in assemble_context still calls fuzzy_search and applies a heavy 0.2 discount as a pure fallback (only adds entities the keyword path didn't already cover; never overrides a keyword-path score). Design principle being restored (user-stated): keywords are the indexing hub. tagged_with relations are created automatically when an entity is saved, so the keyword graph alone is enough for retrieval connectivity. Explicit elaborates / refers_to edges are editorial nuance, not required for findability. ## A.7 — two-level diversity quota (per-search-term + per-keyword) When A.6 went live the top recall results for narrow-subject queries were dominated by a few popular hub keywords (CityFalcon ~42 entities, user-profile ~30, BrainDB ~12, ...). Each of those keywords was strongly matched by the broad multi-word queries the LLM was issuing, so their entities crowded top-N at near-identical scores; the narrow-subject fact (e.g. Petros, only 1 entity tagged) fell below the cut. Two complementary mechanisms, sharing ONE counter, fix this: L1 — per-search-term reservation: each query in queries[] gets ceil(max_results × per_query_share / num_queries) reserved slots filled from that query's OWN top-ranked entities. So a focused narrow query ALWAYS surfaces something in the result, no matter how broad the other queries are. L2 — per-keyword quota (geometric decay): walking the remaining (open) slots in final_rank-desc order, each new dominant matched keyword gets a halving allowance (50% / 25% / 12.5% ... of max_results, floor 1). Stops a popular keyword from monopolising the open portion. They share one bookkeeping dict (seen: kw_id -> remaining), so a keyword's allowance is decremented by BOTH L1 reservations and L2 walks — no double-spending, no conflict. The full coexistence rules are documented in the docstring of _apply_two_level_quota in braindb/services/context.py. Please read that block before touching the function; the no-conflict property depends on the shared counter. assemble_context now also tracks per-query scores (text_scores_by_q, embedding_scores_by_q) alongside the existing max-aggregated dicts, so L1 can rank entities by THAT query's own combined score (using the same geometric-mean / missing_signal_penalty merge per query). ## Prompt nudge — recall_memory docstring teaches narrow-query strategy A multi-word query like "Petros person identity profile" matches the short "Petros" keyword at only ~0.4 fuzzy (trigram dilution). The 1-word query "Petros" matches it at ~1.0 and surfaces the Petros fact at the top. To exploit this, the recall_memory tool's docstring (which the LLM reads as the tool description) now explicitly tells the model: - prefer 2-4 short focused queries over one long phrase - include bare subject names as standalone queries - example: ["Petros", "Selonda Saronikos fish farm", ...] - the per-search-term quota guarantees each angle gets representation, so adding the bare keyword is free The narrow strategy + L1 reservation together unlock the narrow-subject case: the LLM issues a single-keyword query for the subject, that query reserves slots in the result, the subject's fact tops those slots. Also bumped: agent recall_memory default max_results 15 → 30 (via new settings.recall_default_max_results). The /memory/context API schema default was already 30; this brings the agent tool in line. ## Verification (live, deepinfra/Gemma-4-31B) | Query | Petros position | final_rank | |--------------------------------------------------------|-----------------|------------| | ["Petros"] (narrow) | #1 | 0.838 | | ["Petros", "Selonda Saronikos fish farm", "Dimitrios manager"] | #1 | 0.839 | | ["Petros person identity profile", "Petros relation to Dimitris", "Petros CityFalcon"] (broad-only) | #5 | (was: NOT in top-30) | Dimitrios Koutsoumpos /agent/query regression: 49.9s, 1362-char structured grounded answer.

No code changes in this commit — text only. What the docs now reflect about recall: - BOTH the fuzzy and embedding pathways of /memory/context are keyword-mediated (was: only embedding via keywords). Each query matches against keyword entities; entities surface via tagged_with. - A two-level diversity quota is applied: L1 (per-search-term): each query in queries[] reserves a share of the result slots, filled from THAT query's own top-ranked entities. Knob: per_query_share=0.5 in config.py. L2 (per-keyword, halving): each dominant matched keyword gets a 50% / 25% / 12.5% ... allowance, floor 1. Stops one popular keyword from monopolising top-N. Knob: keyword_quota_halving =0.5 in config.py. - Query strategy: prefer MULTIPLE narrow queries (single keywords, bare names) over one long phrase. Keywords are short, so a short query matches them cleanly; a long phrase dilutes pg_trgm similarity against the keyword. - max_results default for /memory/context and the recall_memory agent tool is now 30 (was 15 on the agent side; the API schema was already 30). - Scoring pool internally considers up to 500 keyword neighbours and 500 fuzzy candidates per query (pure SQL/vector — cheap), so narrow keywords aren't excluded before they're evaluated. Knobs: scoring_pool_keyword_neighbors / scoring_pool_fuzzy in config.py. - /memory/search (raw fuzzy) and the quick_search agent tool stay keyword-blind — they are intentionally the "match arbitrary content" path, not the sophisticated retrieval path.

Both use unittest.mock to stub the SDK so they're fast (~3 s combined) and deterministic — no live LLM dependency. tests/test_final_answer_rename.py — 14 tests: - 4 parametrised: every typed `submit_*` tool exposes name 'final_answer' to the SDK (introspecting FunctionTool.name). - StopAtTools on all four built agents contains 'final_answer'. - 3 parametrised: prompt files (system_prompt, wiki_maintainer_prompt, wiki_writer_prompt) have ZERO 'submit_result' references after the rename — guards against the LLM seeing a mismatched contract. - Slot pattern regression coverage (already shipped in 8560cfa but crucial under the new design): install/release isolation, nested parent→child slot bookkeeping, record_submit outside any active slot is a silent no-op. - run_typed raises RuntimeError when Runner.run completes without any submit_* having fired (strict-mode invariant). - run_typed returns the typed Pydantic instance when the slot WAS populated during the run. - Pydantic typed-arg validation: each schema model rejects malformed input — the SDK-level @function_tool argument schema is the source of truth for "the LLM cannot emit garbage args". tests/test_runhooks_countdown.py — 7 tests: - Idle when far from max_turns (no injection). - Fires once at threshold (input_items mutated; nudge mentions 'final_answer'). - Idempotent (no re-inject on subsequent turns). - threshold=0 disables entirely. - max_turns < threshold pathological config doesn't crash. - Normal completion (submit before threshold) leaves input_items untouched. - Internal hook exceptions are swallowed so the agent loop survives a future SDK shape change. tests/test_search.py — one existing test updated to reflect Stage A.6's keyword-mediated retrieval (`c4e4a2f`): the previous version asserted that an entity reachable ONLY via graph traversal from a directly- matched seed also appeared in the top-N. After A.6's redesign, graph-traversed entities get a default seed_score (0.3) with relevance fade (0.6 at depth 1), so their final_rank lands around 0.09 — correctly out-competed by entities with real direct matches in a populated DB. The graph_expand MECHANISM still runs; its output ranks low. That's the documented architectural choice (see README.md "How Retrieval Works" and BRAINDB_GUIDE.md "How Search Works"). The test now keeps the direct-keyword-match assertion (still strictly true) and notes the broken-by-design B-via-graph assertion in the docstring with a TODO pointing at a proper isolated unit test of `graph_expand` at the service level.

Same branch, no push. Layer 1 — rename the termination tool to `final_answer` ------------------------------------------------------- Background: weak models (e.g. Qwen3.6-27B-AWQ-INT4) sometimes wrap their answer in prose on the final turn instead of calling the typed termination tool, breaking the strict-final contract from 8560cfa. External research (Grok, openai-agents issues #800 and #1778, smolagents docs) consistently points at the tool name being part of the problem — `submit_result` is generic; `final_answer` is the training-distribution convention. Smolagents uses it; LangGraph forums recommend it; community examples on LiteLLM + local models converge on it. The rename is cosmetic but touches everywhere the name surfaces: braindb/agent/tools.py — `name_override="final_answer"` on the four typed submit_* @function_tool decorators; docstring tweaks braindb/agent/agent.py — `StopAtTools(["final_answer"])`; all submit_result references in comments / docstrings updated braindb/agent/schemas.py — docstring mentions braindb/agent/prompts/system_prompt.md — every reference braindb/agent/prompts/wiki_maintainer_prompt.md — every reference braindb/agent/prompts/wiki_writer_prompt.md — every reference braindb/ingest_watcher.py — the chunk + central-review prompts the watcher injects; comment mentions The four submit_* tools keep their Python identifiers (submit_answer, submit_maintainer, submit_wiki, submit_subagent) — they're internal. Only the LLM-visible tool name flips. The Pydantic argument schemas (AgentAnswer, MaintainerDecision, WikiWriteResult, SubagentResult) are untouched; the slot-based capture in braindb/agent/run_state.py is untouched. Layer 3 — RunHooks runtime countdown nudge ------------------------------------------- Background: even with the right tool name, a model can over-explore and run out of turns before finalising. The SDK's RunHooks.on_llm_start callback receives the mutable `input_items` list that's about to be sent to the LLM (see openai-agents/lifecycle.py and agents/lifecycle.py's RunHooksBase). Appending one user message to that list adds a synthetic prompt the model sees on its next turn — the canonical SDK extension point for context injection. New file `braindb/agent/hooks.py` (~80 lines including docstring + inline comments): class CountdownHooks(RunHooks): - constructor: max_turns, threshold, tool_name - on_llm_start: counts turns; when ≤ threshold turns remain AND not _fired, appends ONE synthetic user message to the input_items list: "You have N tool call(s) left before the run is forced to end. Finalise NOW by calling `final_answer` with your answer. Do not start any new research; deliver what you already know via `final_answer`." Flips `_fired = True` so the nudge is never repeated. - all hook body wrapped in `try/except` that logs and swallows — a future SDK shape change must NOT bring down the agent loop. New setting in `braindb/config.py`: agent_countdown_threshold: int = 5 (Set to 0 to disable the nudge entirely; useful as an opt-out.) Wired into `braindb/agent/agent.py::run_typed`: hooks = CountdownHooks(max_turns=turns, threshold=settings.agent_countdown_threshold, tool_name="final_answer") await Runner.run(..., hooks=hooks) One added kwarg to Runner.run. No other changes to the run loop. Why this combination works -------------------------- The two layers attack the prose-terminal failure on different fronts: - Layer 1: the model RECOGNISES the right tool name (training- distribution match), reducing the rate at which it ignores the typed-final mandate. - Layer 3: if it would otherwise run out of turns, the model gets an unambiguous in-conversation reminder ("you have N left, finalise now") — the same kind of nudge a human supervisor would give. Together they close the failure mode without changing scoring math, without IDF, without a formatter-agent handoff, without weakening the typed-final contract. Tests covering both layers landed in cf1caf7; full pytest suite is green (58 passed) including the live deepinfra/agent smoke test. --- braindb/agent/agent.py | 30 +++-- braindb/agent/hooks.py | 122 ++++++++++++++++++ braindb/agent/prompts/system_prompt.md | 20 +-- .../agent/prompts/wiki_maintainer_prompt.md | 2 +- braindb/agent/prompts/wiki_writer_prompt.md | 4 +- braindb/agent/schemas.py | 4 +- braindb/agent/tools.py | 22 ++-- braindb/config.py | 7 + braindb/ingest_watcher.py | 8 +- 9 files changed, 179 insertions(+), 40 deletions(-) create mode 100644 braindb/agent/hooks.py diff --git a/braindb/agent/agent.py b/braindb/agent/agent.py index 65bf6a6..623c7a4 100644 --- a/braindb/agent/agent.py +++ b/braindb/agent/agent.py @@ -1,13 +1,13 @@ """ BrainDB internal agent — builder and runners. -Convention (absolute): every agent run finishes via the `submit_result` +Convention (absolute): every agent run finishes via the `final_answer` trick, and that tool's argument is ALWAYS a typed Pydantic model.

Gemma did all the requested work in 4 turns (save_fact + recall_memory + 2 create_relations), then ended the run with plain prose. Strict mode correctly returned 500 — but the data WAS persisted, only the closing wrapper was missing. Layer 3 didn't help: at turn 4 we're nowhere near max_turns - threshold = 10. This commit closes that gap without weakening the strict-final contract. When `Runner.run` returns with an empty slot (`final_answer` never fired), `run_typed` now appends a synthetic user-role correction message to the conversation history the SDK already exposes via `RunResult.to_input_list()`, and re-invokes `Runner.run` ONCE with a small budget (`agent_retry_max_turns=3`, plenty for the model to just call final_answer). If the retry produces a valid typed payload -> return it (HTTP 200, success). If the retry ALSO fails -> raise RuntimeError, as today, because the model truly refuses the contract even after explicit correction. The retry uses the SDK's own conversation mechanism — no parsing, no monkey-patching, no acceptance of prose as a valid answer. It applies uniformly to all four agents (general, maintainer, writer, subagent) because `run_typed` is the single entry point. User-stated framing: "we tell the model what it did wrong in the conversation, so we do not try to parse it, but say to the agent in the conversation this is not valid you need this". Combined with Layers 1 + 3, Stage C now covers both directions of the prose-terminal failure mode: - Layer 1 (rename): matches the training distribution, reducing the rate at which weak models forget the closing tool. - Layer 3 (countdown nudge): catches over-explorers approaching max_turns. - Layer 4 (retry-with-correction): catches under-explorers / forgetters who finish the task quickly and emit prose. Implementation -------------- braindb/agent/agent.py::run_typed — wrap the existing single Runner.run call. If slot.value is None after the first attempt and retry is enabled, build retry_input = result.to_input_list() + [correction], re-run with a fresh CountdownHooks instance (separate turn counter), check the slot again. ~50 lines added (the retry branch + its own final raise path). The opt-out path (retry disabled) preserves the original immediate strict-raise behaviour byte-for-byte. braindb/config.py — two new settings: agent_retry_on_missing_final: bool = True # master switch agent_retry_max_turns: int = 3 # retry budget Tests ----- tests/test_final_answer_rename.py — 4 new tests: test_run_typed_retries_when_first_attempt_missing_final First attempt has no final_answer; second attempt fires it -> returns the typed payload. Asserts call_count == 2. test_run_typed_raises_when_retry_also_fails Both attempts end without final_answer -> still raises with the "even after correction" message. Asserts call_count == 2 (one retry, then give up). test_run_typed_retry_disabled_via_setting agent_retry_on_missing_final=False -> first failure raises immediately, no retry. Asserts call_count == 1. test_run_typed_correction_message_appended_on_retry Captures the input passed to the second Runner.run call. Asserts it is a list, starts with result.to_input_list(), ends with a user-role dict whose content mentions `final_answer`. Full pytest suite: 63 passed (entities + relations + search + ingest + split_chunks + final_answer_rename + runhooks_countdown + live deepinfra agent smoke). Includes the live LLM smoke test which now exercises both the rename and the retry path (any prose-terminal in the smoke run would be silently retried; the test still asserts 200 + grounded answer). What stays untouched -------------------- - Pydantic schemas (AgentAnswer, MaintainerDecision, WikiWriteResult, SubagentResult). - The slot pattern in braindb/agent/run_state.py. - The CountdownHooks class (used by both attempts, fresh instance per attempt so its counter doesn't carry over from the first run). - Every agent prompt — they already say "call final_answer"; the retry mechanism just gives the model one more nudge after a failure to comply. - The wiki pipeline, the scheduler, all REST routes. What this does NOT do --------------------- - Does NOT retry multiple times. One retry, then real failure. No loops, no escalation. - Does NOT silently accept prose. Prose-terminal still raises if even the retry can't extract a final_answer. - Does NOT change scoring math, the keyword-mediated retrieval, the diversity quotas, or any of the Stage A improvements. --- braindb/agent/agent.py | 84 ++++++++++++++++---- braindb/config.py | 13 ++++ tests/test_final_answer_rename.py | 124 ++++++++++++++++++++++++++++++ 3 files changed, 207 insertions(+), 14 deletions(-) diff --git a/braindb/agent/agent.py b/braindb/agent/agent.py index 623c7a4..861bd94 100644 --- a/braindb/agent/agent.py +++ b/braindb/agent/agent.py @@ -184,23 +184,79 @@ async def run_typed( ) try: logger.info("Running typed query (%s): %s", agent.name, query[:160]) - await Runner.run(starting_agent=agent, input=query, max_turns=turns, hooks=hooks) + result = await Runner.run( + starting_agent=agent, input=query, max_turns=turns, hooks=hooks, + ) payload = slot.value - if not isinstance(payload, expected_cls): - # NOTE: this fires whenever `Runner.run` returns and no `submit_*` - # tool was called.

The maintainer was failing every tick with `Invalid JSON input for tool final_answer: 1 validation error for final_answer_args / payload.target_wiki_no Input should be a valid integer`, even though the model was clearly trying to send a valid `skip` decision. Two compounding root causes: 1. SDK default `strict_mode=True` activates OpenAI structured-outputs strict JSON schema, which forces EVERY property of the embedded Pydantic model into the schema's `required` list — overriding Pydantic's own view that `field: T | None = None` and `default_factory=list` are optional. Weak models then dutifully try to supply something for the "required" target_wiki_no on a `skip` action, sending the empty string "" rather than nothing at all. 2. Even with strict_mode off, weak/quantised models routinely emit the wrong-type variant for nullable fields: - target_wiki_no="" instead of null for skip/create/ambiguous - consolidate_nos=null instead of [] for non-consolidate - proposed_name="" instead of null for non-create Pydantic correctly rejects all three; the run dies in the closing tool call after all the work was done — exactly the failure mode Layer 4 (retry-with-correction) cannot recover from because the typed-final tool itself is broken. Fix ---- braindb/agent/tools.py — `strict_mode=False` on all four @function_tool decorations (submit_answer, submit_maintainer, submit_wiki, submit_subagent). The SDK-emitted JSON schema now faithfully follows Pydantic's required list. The typed contract is unchanged: Pydantic still validates the parsed args inside the tool body, so a malformed payload still raises ValidationError exactly like before; we just stop demanding fields the action doesn't need. ~10-line comment block added inline explaining why this matters and how it was diagnosed. braindb/agent/schemas.py — three layers of defence: a) Sharpened field descriptions. Each action-dependent field now spells out exactly when it's required AND what to send for other actions ("MUST be JSON null. Do NOT use empty string, 0, or 'n/a' — use literal null."). The descriptions are the LLM-facing contract, so making them unambiguous is the primary lever. b) `mode="before"` field_validators on the four affected fields: MaintainerDecision.target_wiki_no (coerce_to_int_or_none), MaintainerDecision.proposed_name (coerce_empty_to_none), MaintainerDecision.consolidate_nos (coerce_to_list), WikiWriteResult.canonical_no (coerce_to_int_or_none). These accept "", "null", "none", "n/a" (any case, whitespace ok) → None for nullable fields; None / "" → [] for list fields; numeric strings → int. They are forgiving safety nets, NOT replacement contract — the descriptions still say "use null". c) Three shared coercion helpers at module top (_coerce_empty_to_none, _coerce_to_int_or_none, _coerce_to_list) so the validators stay one-liners. tests/test_final_answer_rename.py — 6 new coercion tests covering each variant: empty string, null-string sentinels (Null/NULL/None/N/A all coerce), numeric-string-to-int, null→[] for list fields, WikiWriteResult canonical_no, and a happy-path regression test that confirms well-typed values still pass through untouched. Test count: 73 passed (was 67) — 6 added for the coercion behaviour. No other test changes.

Two observed shapes: payload # missing outer `payload` key Input should be a valid dictionary payload.result # outer wrapper present but Field required [type=missing # inner dict missing required # SubagentResult.result key The generic "call final_answer NOW with a concise summary" correction gives the model the *intent* but not the *shape*. The SDK's @function_tool convention wraps the typed model under a top-level `payload` key (because the tool signature is `submit_*(payload: )`), so the LLM has to emit: final_answer({"payload": {"result": "..."}}) NOT final_answer({"result": "..."}) Weak/quantised models lose this distinction under correction pressure, especially for the simplest schema (`SubagentResult` has one field — they collapse the wrapping). Fix ---- braindb/agent/agent.py — new `_expected_shape_hint(expected_cls)` helper that introspects the Pydantic model's JSON schema and renders a literal JSON-call template: {"payload": {"result": ""}} # SubagentResult {"payload": {"answer": ""}} # AgentAnswer {"payload": {"action": "attach", # MaintainerDecision "rationale": ""}} # — uses first Literal # value, not a placeholder, # so the example itself # validates if sent verbatim {"payload": {"mode": "create", "body": ""}} # WikiWriteResult Only REQUIRED fields are included (optional/nullable fields are omitted so the LLM doesn't fabricate values for them). Enum / Literal fields get the first allowed value rather than a `` string, so an LLM that copies the template verbatim still produces a valid call. The correction message in `run_typed` now embeds this literal shape between explicit "send EXACTLY one argument named `payload`" framing and "Do NOT omit the outer `payload` key. Do NOT wrap the payload as a string" anti-patterns. Both error variants observed live are spelled out as things NOT to do. Tests ----- tests/test_final_answer_rename.py — 4 new parametrized tests over the 4 typed models: test_expected_shape_hint_covers_required_keys[answer|maintainer|wiki|subagent] - JSON parseable - Always wraps inner dict in `payload` - Every Pydantic-required field appears by name - Literal/enum fields get a valid value (not a placeholder string) Plus a strengthened assertion on the existing correction-message test: test_run_typed_correction_message_appended_on_retry Now also asserts `"payload"` AND `"answer"` (the required key for AgentAnswer) appear in the correction content — proves the shape hint is being injected, not just the generic plea. Full pytest suite: 77 passed (was 73) — +4 shape-hint tests. What stays untouched -------------------- - The retry budget (`agent_retry_max_turns=3`) and master switch (`agent_retry_on_missing_final=True`) are unchanged. - The schemas, the slot pattern, the prompts, all REST routes. - The Pydantic field validators added in 6b20b9f (the lenient coercion safety net) — those are orthogonal: they help when the LLM emits the right SHAPE with wrong-TYPE values; this commit helps when the LLM emits the right TYPE but wrong SHAPE. Together they cover both axes of the "weak model finalising under pressure" failure mode. --- braindb/agent/agent.py | 81 ++++++++++++++++++++++++++++--- tests/test_final_answer_rename.py | 60 +++++++++++++++++++++++ 2 files changed, 135 insertions(+), 6 deletions(-) diff --git a/braindb/agent/agent.py b/braindb/agent/agent.py index 861bd94..a05a887 100644 --- a/braindb/agent/agent.py +++ b/braindb/agent/agent.py @@ -20,12 +20,14 @@ (a ContextVar). `run_typed` reads it back after `Runner.run` returns. asyncio's per-Task context isolation makes nested/parallel runs safe.

No new endpoints, no new agent tools, no server-side code — pure guidance updates. What changed and why -------------------- The two skills (skills/braindb/SKILL.md, skills/braindb-agent/SKILL.md) were missing three things: 1. Zero wiki awareness. Wikis are first-class entities with a maintainer + writer pipeline running every 60s, but neither skill mentioned them — not as recall targets, not as save targets, not as a thing that exists. 2. Agent skill header still said "LiteLLM + NVIDIA NIM". The default has been deepinfra/google/gemma-4-31B-it (via LLM_PROFILE) for a while. 3. Both skills said "be proactive about saving" but neither told Claude to ASK the user first. The user just confirmed that ALWAYS-ASK is the desired policy: RECALL → ASK → SAVE. skills/braindb/SKILL.md (+118 lines net) - TOOL PRIORITY: new bullet 4 introducing wikis as a first-class entity type with the browse paths. Existing 4-bullet hierarchy preserved; /memory/sql exception wording untouched. - SAVE / Saving philosophy: replaced "save everything worth remembering" framing with "always recall first; if net-new, ASK the user; only persist on yes." Exception path for user-stated rules ("from now on, always X") — save without an extra confirmation but surface the action. - NEW WIKIS section between EXPLORE and INGEST, three subsections: recall (GET /entities?entity_type=wiki + GET /entities/); indirect write (default — save facts tagged with the subject's keyword, optionally POST /wiki/cron to nudge the pipeline, inspect via /wiki/jobs?status=pending); direct write (power user, rare — POST /wikis with the "bypasses dedup pipeline" caveat and the keyword-UUID lookup tip). Explicitly notes that /wiki/maintain and /wiki/write are NOT documented here because they're claim-based (take no target) and only make sense inside the scheduler. skills/braindb-agent/SKILL.md (+60 lines net) - Header: drop "LiteLLM + NVIDIA NIM"; describe as "LiteLLM with pluggable provider via LLM_PROFILE; defaults to deepinfra/google/gemma-4-31B-it." - TOOL PRIORITY: tighten the SQL-avoidance sentence to match the direct skill's emphasis ("if you're tempted to phrase a request as 'run a SQL query that finds…', stop"). Add one paragraph noting wikis are first-class and the agent surfaces them through recall automatically — no special endpoint, no user action. - NEW "Proactive save — but ASK the user first" subsection replacing the previous "Be proactive" one-liner. Spells out the RECALL → ASK → SAVE flow with the exact phrasing Claude should use ("I haven't seen this before — should I save it to BrainDB?"). Lists what's worth flagging (identity, preferences, project context, decisions, URLs, inferences-about-the-user). Clarifies the goal: capture what the user gives that ISN'T already in BrainDB, not scrape every utterance. - Examples table rewritten into TWO tables (Recall, no confirmation; Save, three-column "what Claude says to the user" + "what Claude sends to the agent on yes") to make the ASK pattern visually obvious. Verification ------------ - grep submit_result in both → 0 hits (regression check; the rename to final_answer already shipped) - grep "NVIDIA NIM" in agent skill → 0 hits - grep LLM_PROFILE in agent skill → 1 hit - grep -i wiki → 24 hits in direct skill, 2 in agent skill - grep "RECALL .* ASK .* SAVE" → present in both The skill-sync block at the top of each in-repo SKILL.md (diff-against-cached-copy → SKILL_UPDATE_AVAILABLE) auto-detects the new versions on next /braindb or /braindb-agent invocation and prompts the user to refresh ~/.claude/skills//SKILL.md.

No new routes, no new agent tools, no server-side code. - CLAUDE.md (already has the wiki-via-pipeline framing in its TOOL PRIORITY block). - The agent prompts (system_prompt.md, wiki_maintainer_prompt.md, wiki_writer_prompt.md) — they govern in-agent behaviour, not what skill users tell the agent to do. - The .repo_path skill-sync mechanism (still works as-is). --- skills/braindb-agent/SKILL.md | 76 ++++++++++++++++++--- skills/braindb/SKILL.md | 122 ++++++++++++++++++++++++++++++++-- 2 files changed, 182 insertions(+), 16 deletions(-) diff --git a/skills/braindb-agent/SKILL.md b/skills/braindb-agent/SKILL.md index e7565b4..bf02c66 100644 --- a/skills/braindb-agent/SKILL.md +++ b/skills/braindb-agent/SKILL.md @@ -6,7 +6,7 @@ allowed-tools: Bash Read ## BrainDB Memory Agent -BrainDB has its own internal agent (LiteLLM + NVIDIA NIM) that handles all memory operations.

The SDK then hands that string to Pydantic via `AgentAnswer.model_validate("")`, which raises: Input should be a valid dictionary or instance of Verified twice live on Qwen: once on the general agent (`/agent/query` "Sawki's brother" → 500 after Layer 4 retry also failed); once on the wiki maintainer (parallel triage tick on a `_pytest_*` orphan, same Pydantic shape error). Both attempts were emitting structurally valid JSON inside the string — the LLM followed the schema; the SDK just doesn't unwrap twice. Fix ---- braindb/agent/schemas.py — new `_maybe_parse_json_string` helper + `@model_validator(mode="before")` on each of the four typed submit models (AgentAnswer, MaintainerDecision, WikiWriteResult, SubagentResult). The validator runs BEFORE field-level validation: - If input is a `str`, attempt `json.loads(v)`. If it parses to a dict, return that dict; field validators then run on each field's value exactly as if the LLM had sent a dict to begin with. - If it parses to anything else (list / int / null / bool), let Pydantic raise the usual "valid dictionary" error so the LLM gets a clear correction on Layer 4 retry. - If json.loads raises (non-JSON string), let Pydantic raise the usual error. No silent acceptance of garbage. - If input is a dict, pass through unchanged — well-behaved providers (deepinfra, OpenAI native via LiteLLM, Anthropic) see EXACTLY the same code path as before this commit. The LLM-visible JSON schema does NOT change. We don't advertise string-form acceptance to any model. This is purely a server-side safety net — same pattern, same justification, and same one-place edit as the nullable-field coercion in 6b20b9f. The existing field-level coercers (target_wiki_no="" -> None, consolidate_nos=None -> [], etc.) still run on the post-parse dict, so a Qwen submission like payload="{\"action\": \"skip\", \"target_wiki_no\": \"\", \"rationale\": \"...\"}" now goes: raw string -> _maybe_parse_json_string -> dict -> field validators (target_wiki_no="" -> None) -> typed MaintainerDecision(action="skip", target_wiki_no=None, ...) Tests ----- tests/test_final_answer_rename.py — 7 new tests: test_agent_answer_accepts_json_string_payload test_maintainer_decision_accepts_json_string_payload test_wiki_write_result_accepts_json_string_payload test_subagent_result_accepts_json_string_payload Each: model.model_validate() succeeds with the right typed instance. test_dict_payload_still_passes_through_unchanged All four models: dict input behaviour is byte-identical to pre-commit. Regression cover for deepinfra / Gemma / OpenAI. test_non_json_string_still_fails_clearly Plain text, JSON list, JSON string-literal, JSON number, JSON null all still raise ValidationError. We don't accept garbage. test_json_string_with_missing_required_field_still_fails A JSON-string of a dict missing required fields raises with the right field name in the error. We parse the JSON but do NOT silence structural problems — the LLM still sees a correctable error. Full pytest suite: 84 passed (was 77, +7). Live verification ----------------- Pre-fix Qwen recall query: HTTP 500, Layer 4 retry ALSO failed, `payload Input should be a valid dictionary` on both attempts. Post-fix Qwen recall (same query "what is the main characteristic of the brother of Sawki?"): HTTP 200 in 18 seconds, two-tool clean run (`recall_memory` -> `final_answer`), grounded answer ("exceptionally clever, despite not speaking Greek well"). No Layer 4 retry needed — first attempt succeeded once the SDK validator could unwrap the JSON-string. What this does NOT do --------------------- - Does NOT change the @function_tool schema seen by the LLM. - Does NOT silence Layer 4 retries — they still fire when the LLM truly fails to call final_answer; just no longer triggered by the unwrap-once SDK quirk. - Does NOT change deepinfra / OpenAI / Anthropic behaviour. Dict inputs flow through the validator untouched. - Does NOT widen the typed-final contract. The final return is still a validated Pydantic instance, exactly as before. Combined with the prior commits this closes the Qwen-side limitation: the typed-final + retry-correction architecture now survives weak / quantised models reliably on both deepinfra/Gemma and Qwen via vLLM, without weakening the strict-final contract. --- braindb/agent/schemas.py | 66 ++++++++++++++++++- tests/test_final_answer_rename.py | 105 ++++++++++++++++++++++++++++++ 2 files changed, 170 insertions(+), 1 deletion(-) diff --git a/braindb/agent/schemas.py b/braindb/agent/schemas.py index e0d1281..483dc31 100644 --- a/braindb/agent/schemas.py +++ b/braindb/agent/schemas.py @@ -10,9 +10,10 @@ These mirror the style of `braindb/schemas/` (the REST layer); they reuse the existing pydantic dependency — no new dependency, no new machinery.

With max_turns=15 the SDK forced termination and Layer 4 retry had to recover. With the old threshold=5 the nudge fired only at turn 10 and its wording was aggressive ("Finalise NOW... Do not start any new research") — right tone for the last few turns, but too sharp when 8 turns were still on the table. This tune addresses three things asked for by the user: 1. Increase the default turn budget *slightly* (15 -> 20). Gives deep-research models breathing room; finishes-fast providers (deepinfra/Gemma) are unaffected because they never get close. Lower than ~15 will regress Qwen behaviour and is documented as such on the setting and in .env.example. 2. Start the countdown earlier (threshold 5 -> 8). With the new max_turns=20 the nudge fires at turn 12 instead of 15 — the model gets ~8 turns of "wrap up" runway instead of 5. 3. Soften the wording from "submit NOW" to "start wrapping up". But ONLY when the budget is generous. The same hook is reused by the Layer 4 retry path with max_turns=3, where soft framing would be the wrong message. Solution: pick tone from `self.max_turns` alone, no new constructor flag: max_turns > 5 -> SOFT: "Heads up: you have N tool calls left in this run. Start wrapping up — synthesise what you have already gathered and prepare to call `final_answer`. Focused gap-filling is fine; avoid opening brand-new lines of investigation." max_turns <= 5 -> HARD: "You have N tool calls left. Call `final_answer` with your answer now. Do not start new research." The retry path (max_turns=3, settings.agent_retry_max_turns) naturally lands in the hard branch — no special-casing. Files ----- braindb/config.py — two defaults bumped, docstrings expanded to explain why and what lower values cost. braindb/agent/hooks.py — `_format_nudge` rewritten as a tone-aware formatter. Constructor signature, `on_llm_start` plumbing, the `_fired` flag, the defensive try/except all unchanged. ~25 line diff inside the helper plus a docstring explaining the tone heuristic. .env.example — added two commented-out reference lines (AGENT_MAX_TURNS / AGENT_COUNTDOWN_THRESHOLD) so future operators who copy the example see the knobs and the warning about lowering below ~15. The lines are commented so the code defaults rule; they're documentation, not configuration. tests/test_runhooks_countdown.py — three new tests: - test_soft_tone_when_max_turns_above_threshold max_turns=20, threshold=8: nudge fires at remaining=8 with "wrapping up" + "gap-filling" wording; does NOT contain the hard-tone "with your answer now" phrase. - test_hard_tone_when_max_turns_at_retry_budget max_turns=3 (Layer 4 retry value), threshold=8: fires on turn 1 with "with your answer now" wording; does NOT contain the soft-tone "wrapping up" phrase. - test_remaining_plural_grammar Both tones produce "1 tool call" (singular) and "N tool calls" (plural) correctly. Existing tests stay green — they asserted structural behaviour (fired-once, threshold-respected, exception-swallowing) and the tool name appearing in the message, none of which the tone rewrite changes. Verification ------------ - Full pytest: 87 passed (was 84, +3 tone/grammar tests). - In-container check after restart: docker exec braindb_api python -c "from braindb.config import settings; print(settings.agent_max_turns, settings.agent_countdown_threshold)" -> 20 8 - .env has no AGENT_MAX_TURNS or AGENT_COUNTDOWN_THRESHOLD override (verified by grep) — the bumped defaults take effect. What stays untouched -------------------- - agent_subagent_max_turns (30) — subagents do focused tasks. - agent_retry_max_turns (3) — retry budget is still tight; the hard tone above is the right wording at that scale. - wiki maintainer/writer per-call max_turns (30/30) and ingest watcher per-call max_turns (40/30) — these callers opted into their numbers; the bumped default only changes the fallback used when no max_turns is passed (currently only the general /agent/query path). - The typed-final contract, Layer 4 retry-with-correction, the schemas, the prompts, the wiki pipeline — none of these change. The plan only loosens *pressure*, not the *exit condition*. --- .env.example | 17 ++++++ braindb/agent/hooks.py | 42 ++++++++++++--- braindb/config.py | 27 +++++++--- tests/test_runhooks_countdown.py | 93 ++++++++++++++++++++++++++++++++ 4 files changed, 166 insertions(+), 13 deletions(-) diff --git a/.env.example b/.env.example index c26571d..3c54857 100644 --- a/.env.example +++ b/.env.example @@ -35,6 +35,23 @@ AGENT_MODEL= # (visible via `docker logs braindb_api -f`).

One line, clear and actionable. - The negative instruction: do NOT paste file contents into an /agent/query "Save this file..." prompt. It bypasses extraction, bloats LLM context, and skips the derived_from relations the watcher produces. - The verbose-watch command (docker logs braindb_watcher -f) and the success log lines to look for. - Edge cases: chunked extraction timing on local Qwen vs deepinfra, where errors land, and the content-hash dedup behaviour.

The 600s default deadline caused the scheduler's HTTP client to give up while the api kept working in the background — the write still committed (observed: 89 wikis revised in one hour despite repeated `Read timed out (read timeout=600)` lines in the scheduler log), but the scheduler couldn't see the completion and was less efficient at draining the queue. This is the scheduler's HTTP-client patience knob. The api itself is NOT bounded by it — the agent run finishes on its own clock. Raising this only means the scheduler waits longer before declaring "I gave up" for a single in-flight job. 1200s (20 min) is generous enough that nearly every Qwen body generation completes within the window, while still surfacing genuinely-stuck jobs (e.g. vLLM hung, GPU starved) as failures rather than blocking indefinitely. Files ----- braindb/wiki_scheduler.py — change the os.getenv default from "600" to "1200" on the AGENT_TIMEOUT line; add a docstring above the line explaining why and what the knob actually controls (scheduler's patience, not api processing time). .env.example — add a commented-out WIKI_AGENT_TIMEOUT=1200 reference block, with the same warning about lowering below ~600 regressing Qwen behaviour. The line is commented so the code default rules. Verification ------------ - grep "WIKI_AGENT_TIMEOUT" .env -> empty (no override; default rules). - After `docker compose up -d --no-deps --force-recreate wiki_scheduler`: docker exec braindb_wiki_scheduler env | grep WIKI_AGENT_TIMEOUT -> (empty; running with the code default 1200) OR (when set) WIKI_AGENT_TIMEOUT=1200 - Watch scheduler log for the next ~30 min — "Read timed out" lines should drop sharply now that the client waits long enough for Qwen to finish. What this does NOT do --------------------- - Does NOT change the api's processing time or per-agent max_turns. - Does NOT change the writer / maintainer / agent prompts or schemas. - Does NOT address the underlying "writer rewrites the same wiki repeatedly" pattern (observed in this hour: Dimitrios Koutsoumpos rewritten 8x, Smart Sand 6x).

The scheduler logged `Connection refused`, retried, and the in-flight write itself wasn't killed mid-token (uvicorn waits for "background tasks to complete") — but everything else got bounced: the scheduler's poll, the watcher's health-check, fresh /agent/query calls.

The writer (full-body regeneration) is ~98% of LLM cost; each rewrite paid 5-10 min of recall+subagent overhead to splice in a single new member, even when the existing body already covered 95% of what's needed. Within-tick batching already exists in `next_write_bucket()` — when the bucket claims, it groups ALL pending attach jobs for the same `target_wiki_id` into a single writer call. What was missing is ACROSS-tick batching: a new attach arriving 30 s after the prior write fires triggers a fresh writer call instead of accumulating with the next batch. Fix --- `braindb/services/wiki_jobs.py::next_write_bucket()` — add a cooldown filter to the seed query so an attach bucket becomes claimable ONLY when the OLDEST pending attach for that wiki is at least `ATTACH_COOLDOWN_SEC` (default 300 s = 5 min) old. Once eligible, the existing per-wiki batching scoops up EVERY pending attach for that wiki (including ones inserted during the cooldown window) into one writer call. Self-limiting — no force-claim valve needed, the bucket drains the whole queue for that wiki on each fire. `consolidate` and `create` paths are untouched; the cooldown is gated `job_type <> 'attach' OR ...` in the WHERE clause. The existing `consolidate > attach > create` priority order is preserved. Net effect on the observed hot-subject pattern: ~5 attach jobs per 5-min window land in ONE writer call instead of 5 separate calls. For Dimitrios K's 8/hr → expected ~1-2 writes/hr on the same load, ~80% LLM cost reduction for that subject. Files ----- `braindb/services/wiki_jobs.py`: - new module-level constant `ATTACH_COOLDOWN_SEC` (env-driven, matches the existing `ASSIGNED_LEASE_MIN` / `FRESHNESS_MINUTES` pattern in this file — no config.py touch). - `next_write_bucket()` SELECT gets an extra WHERE branch + a correlated subquery that computes the per-wiki cooldown eligibility. ~12 lines added. - Docstring on `next_write_bucket()` extended to describe the new cooldown semantics. `tests/test_wiki_jobs_grouping.py` (NEW): Eight tests against the live Postgres (port 5433, the docker- compose mapping) covering core cooldown semantics, batching semantics, priority preservation, and edge cases. Each test seeds its own wiki entity + jobs, cleans up in `try/finally`. Test rows use very old timestamps (10 days) so they win FIFO against any pending production rows that may already exist in the running DB. Verification ------------ - `pytest tests/test_wiki_jobs_grouping.py` → 8/8 pass against live Postgres. - Full suite: 95/95 pass (was 87, +8). - `docker exec braindb_api python -c "from braindb.services import wiki_jobs; print(wiki_jobs.ATTACH_COOLDOWN_SEC)"` → 300 (default loaded). - `.env` has no `WIKI_ATTACH_COOLDOWN_SECONDS` override → default rules. What this does NOT change ------------------------- - Routers, agent prompts, schemas, hooks — none of it. - The within-tick batching at wiki_jobs.py:367-377 — unchanged; cooldown gates WHEN the bucket becomes claimable, not WHAT it contains. - The wiki maintainer — still inserts attach jobs the same way; scheduler just claims them with a delay. - The typed-final contract, Layer 4 retry, the JSON-shape coercion — all unchanged. Rollback -------- `WIKI_ATTACH_COOLDOWN_SECONDS=0` in `.env` reverts to today's "fire on every attach" behaviour.

Adds an attach-mode recall-budget block (the user-approved Draft B) directing the writer to focus recall on new members, inconsistencies, and gaps — not on re-fetching settled claims. Why now ------- Observed today on Qwen: each per-attach write spent 5-10 min on recall+subagent overhead even when the prior body already covered 95% of the subject. The combined cooldown (e3ee7c9) plus this hint targets both axes of the same waste pattern: fewer writes overall AND each write does less redundant research. Compatibility ------------- The two rules now coexist without contradiction. The prior 'NOT evidence' framing is rephrased as 'conservatively' caution (prose is still not evidence; uncited or contradicted claims still don't anchor the new body). The new Draft B block sits underneath as recall-budget guidance, not as 'trust everything the body says'. ~13 lines added to the prompt; the existing Steps 1-3 protocol is byte-identical. Tests ----- tests/test_final_answer_rename.py — new `test_writer_prompt_has_attach_mode_efficiency_hint` asserting the Draft B header, all three bullet keys, the 'conservatively' rephrasing, and the closing balance phrase are all present in the prompt.

Big wikis no longer have to fit twice in the model context window (once in, once out) on a single attach pass. The section anchors are the `` HTML-comment markers the writer prompt already mandates (pre-flight on prod data: 88/88 active wikis have markers; the one un-markered wiki was a corrupted leftover and was retired). Strict-markers contract enforced: tools error if a target body has no markers, no H2 fallback. Optimistic concurrency via the existing `wikis_ext.revision` column — every read returns the current revision; every write requires it as `expect_revision`. Mismatch returns a "stale revision, re-read first" error string so the LLM corrects itself instead of stomping a concurrent or self-stale edit. Persistence interaction: `WikiWriteResult.body` is now optional (default empty string). In attach mode the router captures pre-run revision; if the agent submits `body=""` AND the revision moved during the run, the router treats the section edits as authoritative content and uses the in-DB body for the finalize path (extract_summary_disambig + reconcile summarises). create/consolidate still require non-empty body. Anti-bloat: - Tools added to existing tools.py, not a new file. - Wired into the writer agent only via a new `extra_tools` arg to _build; zero leakage to query/maintainer agents (verified). - Parser/splice live in a new `services/wiki_sections.py` (kept separate from tool wiring so they unit-test without DB). - Tool docstrings 1-2 lines; section grammar taught once in the writer prompt's new "Section-edit path" block. Verified: - 22 unit tests over the pure parsing/splice/grammar layer (parse identity, append-new, delete, stale-rev class, grouped-refs tolerance, malformed-ref detection). All pass. - Real-wiki parse + roundtrip on three of the largest wikis (Dimitrios Koutsoumpos 22.5K, Dimitris 15.9K, BrainDB 13.6K): zero byte drift. - End-to-end DB roundtrip on the smallest active wiki: revision bump on edit, stale-revision rejection on retry with old token, byte- identical revert. - Tool registration: writer = 26 tools (was 21, +5); query agent and maintainer agent tool sets unchanged. --- braindb/agent/agent.py | 39 ++- braindb/agent/prompts/wiki_writer_prompt.md | 49 +++- braindb/agent/schemas.py | 11 +- braindb/agent/tools.py | 210 ++++++++++++++++ braindb/routers/wiki.py | 62 ++++- braindb/services/wiki_sections.py | 218 ++++++++++++++++ tests/test_wiki_sections.py | 264 ++++++++++++++++++++ 7 files changed, 838 insertions(+), 15 deletions(-) create mode 100644 braindb/services/wiki_sections.py create mode 100644 tests/test_wiki_sections.py diff --git a/braindb/agent/agent.py b/braindb/agent/agent.py index a05a887..acb326d 100644 --- a/braindb/agent/agent.py +++ b/braindb/agent/agent.py @@ -42,12 +42,16 @@ delegate_to_subagent, delete_entity, delete_relation, + delete_wiki_section, + edit_wiki_section, generate_embeddings, get_entity, get_stats, ingest_file, list_entities, quick_search, + read_wiki_outline, + read_wiki_section, recall_memory, save_fact, save_rule, @@ -59,6 +63,7 @@ submit_subagent, submit_wiki, update_entity, + validate_wiki, view_entity_relations, view_log, view_tree, @@ -157,17 +162,22 @@ def _model() -> LitellmModel: ) -def _build(name: str, submit_tool) -> Agent: +def _build(name: str, submit_tool, extra_tools: tuple = ()) -> Agent: """Build an agent.

Composes naturally with the section-edit tools from the prior commit: the dying agent's section edits are already persisted; the successor picks up the work. Mechanism (writer-only, opt-in via token_budget > 0): 1. Token-budget watch in CountdownHooks. Extends the existing Layer 3 hook with an OPTIONAL second nudge driven by a cheap chars/4 estimate of input_items. Original turn-budget behaviour is unchanged when the new knob is left at 0 (default for query/maintainer agents). Two independent fired-once flags so the nudges never suppress each other. 2. handoff_to_successor tool in tools.py. Takes a structured brief (progress_summary + remaining_work). The body records the brief in a per-run handoff slot AND parks a placeholder WikiWriteResult via record_submit so run_typed's typed-final contract is satisfied without it needing to know about handoffs. The writer's StopAtTools list includes the tool name, so the loop halts cleanly. 3. Per-run handoff slot in run_state.py. Mirrors the existing final-answer slot exactly: ContextVar holding a mutable container so cross-Task writes are visible to the wrapper. 4. Respawn loop in routers/wiki.py. After run_typed returns, if the handoff slot was captured, build a successor seed from the brief and re-invoke run_typed. Recur up to agent_writer_handoff_max_depth (default 3); cap-exhaustion is a job failure. Slot is reset between iterations so each successor can also hand off. 5. Writer prompt: new "Context handoff" block explains when to use the handoff tool vs finishing inline, and the brief shape the successor needs to pick up cleanly. Anti-bloat: - No new hook file (extended CountdownHooks). - No new tool module (handoff in existing tools.py). - No new endpoint, no schema change beyond Phase 1. - No forced tool_choice plumbing — strong nudge text + the existing Layer 4 retry-with-correction is the safety net. - Single absolute-token knob (9000 default) instead of per-profile pct math — fires conservatively on bigger windows, safely on Gemma's 13K. One config line. Verified: - 15 new unit tests in tests/test_handoff_hooks.py cover the token estimator (dict / list-of-parts / object shapes), the token nudge (fires on threshold, idempotent, disabled at 0), the independence of turn nudge and token nudge, the handoff slot lifecycle (install, capture, isolated across nested installs, no-op outside scope), and the handoff tool body's dual-slot fill. - Existing 10 CountdownHooks tests still pass — the new fired-flag rename to _fired_turns is back-compat shimmed via a property. - Full suite: 125 pass, 8 pre-existing environmental errors in test_wiki_jobs_grouping.py (those hardcode localhost:5433 and only run from the host). - Wiring smoke: writer has 27 tools (was 21, +5 section + 1 handoff), StopAtTools includes both final_answer and handoff_to_successor, zero leakage to the query or maintainer agents. - Adjusted tests/test_final_answer_rename.py: WikiWriteResult.body became optional in Phase 1, so its required-keys list is now just ["mode"]; the shape-hint test is updated to match. What this does NOT cover (deferred): - Live LLM-driven smoke (force threshold low, run the writer end- to-end, observe one handoff + successor reaches final_answer). That's the Phase 3 task once the scheduler is re-enabled. --- braindb/agent/agent.py | 63 ++++- braindb/agent/hooks.py | 160 ++++++++--- braindb/agent/prompts/wiki_writer_prompt.md | 34 +++ braindb/agent/run_state.py | 52 ++++ braindb/agent/tools.py | 45 ++- braindb/config.py | 17 ++ braindb/routers/wiki.py | 78 +++++- tests/test_final_answer_rename.py | 12 +- tests/test_handoff_hooks.py | 287 ++++++++++++++++++++ 9 files changed, 692 insertions(+), 56 deletions(-) create mode 100644 tests/test_handoff_hooks.py diff --git a/braindb/agent/agent.py b/braindb/agent/agent.py index acb326d..1fe7fbf 100644 --- a/braindb/agent/agent.py +++ b/braindb/agent/agent.py @@ -47,6 +47,7 @@ generate_embeddings, get_entity, get_stats, + handoff_to_successor, ingest_file, list_entities, quick_search, @@ -162,14 +163,23 @@ def _model() -> LitellmModel: ) -def _build(name: str, submit_tool, extra_tools: tuple = ()) -> Agent: +def _build( + name: str, + submit_tool, + extra_tools: tuple = (), + extra_stop_tools: tuple[str, ...] = (), +) -> Agent: """Build an agent.

Writer prompt — clarify `body=""` is ATTACH MODE ONLY in both places the section-edit / handoff blocks mention it. Observed failure mode on a live consolidate: the successor agent inherited the section-edit framing from its handoff brief and submitted final_answer(mode='consolidate', body=""), which the router correctly rejected. The mechanism worked end-to-end; the contract wasn't unambiguous enough for a fresh-context successor that doesn't see the full conditioning of the parent run. Added one explicit "ATTACH MODE ONLY" line in the section-edit block plus one mode-aware qualifier in the context-handoff block. No new sections, no restructuring. 2. agent_writer_handoff_token_budget 9000 → 20000. The 9000 default from the original plan was tuned for Gemma's 13K window (~70%). On Qwen 40K it fires at ~25% which is too eager — routine consolidates that fit fine inline got fragmented across successors. 20000 is ~50% of Qwen's window and ~63% of hosted- Gemma 32K, both safe. On local Gemma 13K it sits above the window so handoff never fires, which is fine — small-context path already fails at initial prompt construction (the section tools can't reach it from there; that's a different fix).

For attach mode on a big wiki the stub points the writer at the section tools it already has (Phase 1) instead of forcing the entire body into the initial prompt. Saves ~7K tokens up-front on a 30K-char wiki; the writer can navigate via read_wiki_outline + read_wiki_section without ever bumping into the model window. Other modes (create/consolidate) and small bodies inline as before — regression-safe. Direct cause of one Phase-3 failure: 30K-char Dimitrios body inlined verbatim brought the writer's first LLM call to 14K tokens. Subsequent tool results pushed accumulated context past Qwen's 40K window before the writer could finish, surfacing as ContextWindowExceededError. The section tools were the exact prescription, but the inlining blocked them from being used. 2. agent/agent.py::run_typed: catch litellm.BadRequestError and retry once with a fresh run; re-raise ContextWindowExceededError immediately (unrecoverable without input truncation, which the prompt-stub fix handles upstream). Direct cause of another Phase-3 failure: Qwen 27B AWQ-INT4 occasionally emits malformed JSON in tool-call args; the OpenAI client raises BadRequestError before the tool body runs. The existing Layer 4 retry only fires when Runner.run returns without final_answer — it never gets a chance when Runner.run itself raises. One bounded retry via the run_typed recursion (gated by `_bad_request_retried` flag) is the cheapest path to recover the transient case without inventing a new retry layer. Anti-bloat properties: - ~27 lines total across two existing files. No new files, no new abstractions, no new dependencies. - Reuses the Phase-1 writer prompt's section-tool block (the stub just points the agent at tools already documented). - Reuses run_typed itself as the retry vehicle (one keyword flag, bounded to depth 1) — no separate helper, no exception-policy module. - ContextWindowExceededError is explicitly NOT retried: pointless without input truncation, and would mask the upstream signal. Verified: - 87 existing tests pass (wiki_sections + handoff_hooks + countdown + final_answer_rename). - Direct sanity-test of _body_block_or_stub across modes/sizes: small body inlines, big attach stubs (~30K → ~470 chars), big consolidate stays inlined, empty body stays as create marker. - Imports clean (litellm.BadRequestError + ContextWindowExceededError). - Live re-test: the writer DID follow the stub's direction to use section tools (read_wiki_outline + read_wiki_section), confirming Fix A's intent works end-to-end. What this does NOT do: - Does not address the writer's discretionary no-op behavior on wikis whose new member feels already-covered. The agent reads sections, decides nothing needs to change, submits body="" with no section edits, and the existing Phase-1 guard correctly fails it. That's a writer-prompt-conservatism question (separate from Qwen-output robustness) — to be tightened in a follow-up if re-triage loops persist in observation. - Does not change the handoff threshold (20K stays; Fix A leaves more headroom under it). - Does not lower recall_memory result caps (already 8K chars). --- braindb/agent/agent.py | 29 +++++++++++++++++++++++++++++ braindb/routers/wiki.py | 29 ++++++++++++++++++++++++++++- 2 files changed, 57 insertions(+), 1 deletion(-) diff --git a/braindb/agent/agent.py b/braindb/agent/agent.py index 1fe7fbf..34d7769 100644 --- a/braindb/agent/agent.py +++ b/braindb/agent/agent.py @@ -27,6 +27,7 @@ from agents import Agent, ModelSettings, Runner, StopAtTools, set_tracing_disabled from agents.extensions.models.litellm_model import LitellmModel +from litellm import BadRequestError, ContextWindowExceededError from pydantic import BaseModel from braindb.agent.hooks import CountdownHooks @@ -270,6 +271,7 @@ async def run_typed( max_turns: int | None = None, *, token_budget: int = 0, + _bad_request_retried: bool = False, ) -> T: """Run a typed agent and return the validated Pydantic instance it submitted.

The job hit attempts=3 → permanently failed → maintainer re-flagged the same orphan member → endless re-triage loop. Root cause: - `reconcile_summarises_additive` only runs after `finalize_wiki_write`. - finalize doesn't run on the empty-body / no-edits path (guard fails). - So even though the body contains `[[ref:UUID]]` for the member, the graph never records the `summarises` relation that would have closed the orphan check on the maintainer side. Two surgical changes (no new abstractions, reuses existing helpers): 1. routers/wiki.py — split the empty-body guard: - if any assigned MEMBER is missing from the current body → still fail (the writer genuinely skipped real work). - else (all members already cited) → call `wiki_jobs.reconcile_summarises_additive` against the in-DB body, finish the jobs as `done`, log a `wiki_write` activity with `no_op=true`. The body is untouched; only the graph catches up. This uses existing `wiki_jobs.parse_refs` for citation detection and the existing reconcile function. ~30 added lines, replaces the prior 7-line failure block. 2. wiki_writer_prompt.md — two clarifications so the agent understands the contract from the inside: - Extends the "be thorough where evidence is fresh; be efficient where the body has it right" line with "but every assigned MEMBER still needs to be cited at least once — the citation is what records the `summarises` relation". - New short "Citation is mechanical, not editorial" block right after "Preserve prior work" explaining the consequence + the remedy (add to the references section if your section edits don't naturally cite a member). ~10 lines of prompt. Verified live on Qwen 27B: - Reset the previously-permanently-failed `attach` on a 30K-char wiki with a member that WAS already cited inline but missing from the references bullet list. The writer worked through identity resolution, recognised "member 67949c16 is cited inline BUT missing from references" (the new prompt rule landed), and submitted final_answer(body=""). Router accepted the no-op, ran reconcile, added 2 missing `summarises` relations (one for this wiki + one for a sibling that also cited the same member but had a stale graph). Job done. Wiki body unchanged. Orphan closed. - 125 tests pass (skipping env-bound test_wiki_jobs_grouping). What this commit does NOT do: - Does not allow body="" + missing-citation no-ops (correctly fails those — the writer skipped real work). - Does not change the writer's section-edit path, the handoff path, or the section-tool prompt block. - Does not touch reconcile semantics — it's still additive, idempotent, and uses inline `[[ref:UUID]]` tokens as the sole signal. --- braindb/agent/prompts/wiki_writer_prompt.md | 17 +++++++- braindb/routers/wiki.py | 43 +++++++++++++++++++-- 2 files changed, 56 insertions(+), 4 deletions(-) diff --git a/braindb/agent/prompts/wiki_writer_prompt.md b/braindb/agent/prompts/wiki_writer_prompt.md index 9b969c3..31ea663 100644 --- a/braindb/agent/prompts/wiki_writer_prompt.md +++ b/braindb/agent/prompts/wiki_writer_prompt.md @@ -43,7 +43,10 @@ focus your `recall_memory` budget on: - gaps the new members open up but the body doesn't yet cover.

Handles the Qwen-class quantised-model quirk where the tool-call args occasionally come over the wire double-escaped. Safety properties (each verifiable by reading the 9-line diff): - Only activates when `isinstance(v, str)` AND first parse yields a string. Compliant providers (deepinfra, hosted-Gemma, well-behaved local models) send dicts directly and never enter the string branch at all — dead code for them. - Only returns a value if the final parse yields a dict. JSON of list/int/null still falls through to Pydantic's normal rejection. - Second parse failure returns the original input unchanged so Pydantic raises the same "Input should be a valid dictionary" error today. - No new file, no new function, no new import, no schema change, no prompt change. Pure extension of one existing helper. Background: live-observed during the Phase 3 follow-up session. Maintainer, subagent, and query agent all hit `payload: Input should be a valid dictionary` failures on Qwen 27B AWQ-INT4. The current validator handled single-escape (Qwen quirk captured in a84c182); this commit extends to the double-escape variant. We don't have direct log evidence of the exact shape Qwen sent in the most recent failure (the SDK validator runs before our `@_verbose` decorator can log the args), so this is a defensive preemption that handles a known quirk without breaking any current acceptance behaviour. Tests: - New: tests/test_final_answer_rename.py::test_double_escaped_json_payload_unwraps - Unchanged: existing single-escape, dict-passthrough, non-JSON rejection, and missing-field rejection tests all still pass (126/126 on full suite). --- braindb/agent/schemas.py | 9 +++++++++ tests/test_final_answer_rename.py | 12 ++++++++++++ 2 files changed, 21 insertions(+) diff --git a/braindb/agent/schemas.py b/braindb/agent/schemas.py index f0b829a..062e309 100644 --- a/braindb/agent/schemas.py +++ b/braindb/agent/schemas.py @@ -55,6 +55,15 @@ def _maybe_parse_json_string(v): parsed = json.loads(v) except (json.JSONDecodeError, ValueError): return v # let Pydantic raise its normal error + # Defensive: occasionally Qwen-class quantised models emit the dict + # double-escaped (the first parse yields a string of JSON, not a + # dict).
