Skills and prompts are sourced from a single configured folder on disk (`skills_folder`).

+# iii-directory
+
+This worker does three things:
+
+1. **Skills** (`directory::skills::*`) — read the markdown docs that workers ship, off local disk. A skill is the "what this worker is and how to use it" doc.
+2. **Prompts** (`directory::prompts::*`) — read slash-command templates a human runs (`/send-email`, `/triage`).
+3. **Registry** (`directory::registry::*`) — browse the public catalogue of workers at `api.workers.iii.dev`, even ones you have not installed.
+
+## How to call any function here
+
+Every function below is called the same way: pass its **callable id** to `agent_trigger`.
+
+```jsonc
+// agent_trigger { function: "directory::skills::list", payload: { } }
+```
+
+**Two kinds of id. Do not mix them up.**
+
+| Kind | Looks like | Where it goes |
+|------|-----------|---------------|
+| **Callable id** (a function) | `directory::skills::get` — uses `::` | the `function:` field of `agent_trigger` |
+| **Skill id** (a document) | `iii-sandbox` or `agent-memory/observe` — uses `/` | the `id:` argument you pass to `directory::skills::get` |
+
+The strings `directory::skills::list` returns under `id` are **skill ids** (documents). To READ one, pass it to `directory::skills::get`. Never put a skill id in the `function:` field, and never put a `::` function id into `get`.
+
+## The 3 calls you will use most
+
+**1. See which workers are installed (start here):**
+```jsonc
+// agent_trigger { function: "directory::skills::index", payload: { } }
+```
+Returns one short block per installed worker. Pick the worker you want.
+
+**2. Read a worker's overview:**
+```jsonc
+// agent_trigger { function: "directory::skills::get", payload: { "id": "iii-sandbox" } }
+```
+The `id` is the bare worker name exactly as `index` printed it.
+
+**3. Read a deeper doc the overview linked to:**
+```jsonc
+// agent_trigger { function: "directory::skills::get", payload: { "id": "iii-sandbox/exec" } }
+```
+Use the exact `id` the overview gave you. Do not invent ids.
+
+**Worker not showing up?** It is probably not installed. Install it, then go back to step 1:
+```jsonc
+// agent_trigger { function: "directory::skills::download_from_registry", payload: { "worker": "iii-sandbox" } }
+```
+
+## Which function for which question
+
+| You want to… | Call this |
+|--------------|-----------|
+| List installed workers (token-light) | `directory::skills::index` |
+| List every on-disk skill (with filters) | `directory::skills::list` |
+| Read one skill doc | `directory::skills::get` |
+| Install a published worker's skills | `directory::skills::download_from_registry` |
+| Pull a skill folder from a GitHub repo | `directory::skills::download_from_repo` |
+| List prompt templates | `directory::prompts::list` |
+| Read one prompt | `directory::prompts::get` |
+| Browse published workers in the registry | `directory::registry::workers::list` |
+| Full registry detail for one worker | `directory::registry::workers::info` |
+| Schemas + triggers for one engine function | `directory::engine::functions::info` |
+
+## Rules a dumb agent gets wrong (read these)
+
+### Rule 1 — Use the id you were given. Do not guess.
+The canonical id is whatever `list` or `index` printed. For a worker overview that is the **bare worker name** (`iii-sandbox`, `iii-database`, `agent-memory`). It is NOT `iii-sandbox/index`, and the `iii-` prefix is NOT removed. When in doubt, call `index` or `list` first and copy the id.
+
+### Rule 2 — `get` is forgiving, but a redirect means you guessed.
+If your `id` does not match exactly, `get` tries to help instead of failing:
+- A short/colloquial name resolves to the full worker: `sandbox` → `iii-sandbox`, `memory` → `agent-memory`.
+- A made-up sub-path built from a function id (e.g. `iii-sandbox/sandbox/create`) collapses to that worker's overview.
+- A trailing `.md`, an `iii://` prefix, or a `SKILL.md`/`SKILLS.md` filename are all accepted.
+
+When `get` redirects, the body starts with `> Note: no skill . Showing instead.` That note is telling you the id you asked for was wrong and you are now reading the worker overview. Read it, then follow its links with the correct ids.
+
+### Rule 3 — Only INSTALLED workers are visible.
+`list`, `index`, and `get` only show skills for workers that are currently installed (plus this `directory` worker and the `iii` engine, which are always visible). A skill you "know" exists will be invisible until its worker is downloaded. If a worker is missing, run `directory::skills::download_from_registry { worker: "" }`, then look again. (If the engine daemon is unreachable at boot, filtering is skipped and everything on disk is shown.)
+
+### Rule 4 — Errors are plain sentences that tell you the fix. Never retry the same input.
+A failed call returns ONE sentence, not JSON:
+
+```
+D110 not_found: skill "iii-sanbox" does not exist. Did you mean: iii-sandbox. Next: call directory::skills::list to browse skill ids; or directory::skills::index to see the per-worker overview.
+```
+
+Do exactly what it says: use an id from `Did you mean:`, or call the function named after `Next:`. Codes you may see:
+
+| Code | Meaning | What to do |
+|------|---------|------------|
+| `D110` | skill id not found | pick one from `Did you mean:`, or call `list` / `index` |
+| `D111` | id was empty/invalid | pass a non-empty skill id |
+| `D112` | you passed a FUNCTION id (`a::b`) to `get` | `get` wants a skill id with `/`; to CALL `a::b`, pass it to `agent_trigger` instead |
+| `D210` | prompt name not found | call `directory::prompts::list` |
+| `D310` | registry worker not found | call `directory::registry::workers::list` |
+
+### Rule 5 — Downloading is the ONLY write. Everything else is read-only.
+Three ways in, same engine. Prefer the two explicit ones so the source is unambiguous:
+- **From the registry:** `download_from_registry { worker: "" }`. Optionally pin `version: "1.2.3"` (exact) OR `tag: "latest"` — one or the other, not both. Default is `tag: "latest"`.
+- **From GitHub:** `download_from_repo { repo: "https://github.com//", skill: "" }`. `branch` defaults to `"main"` (pass `"master"` for old repos).
+- `download` is a flexible alias accepting either set; the two above are clearer.
+
+Downloads overwrite file-by-file, so hand-edited extra files survive a re-pull. A write fires `directory::skills::on-change` / `directory::prompts::on-change` so subscribers (like the `mcp` worker) refresh without re-polling.
+
+### Rule 6 — Prompts need a `description` in frontmatter or they vanish.
+A prompt file at `//prompts/*.md` must have YAML frontmatter with at least `description:`. Files without it are silently skipped by `directory::prompts::list`. The body `get` returns is the markdown after the frontmatter.
+
+### Rule 7 — Registry answers are cached for 60s.
+`registry::workers::list` and `registry::workers::info` cache each unique input for ~60s. Repeating the same call returns the same cached answer. To refresh, wait it out or change a parameter.
+
+### Rule 8 — Before writing code against a worker you have NOT installed, read its registry info.
+`registry::workers::info { name: "" }` returns `api_reference` (functions + triggers with request/response schemas) and `skills_tree` (the docs the bundle ships). This is the same schema shape `engine::functions::info` gives after install, so you can build against it ahead of time.
+
+## `directory::skills::list` filters
+
+`list` returns every visible skill with `id` / `title` / `type` / `description` / `bytes` / `modified_at`. It reads disk live (no cache). Narrow it with optional args:
+- `search`: case-insensitive substring over id, title, and description.
+- `prefix`: exact id prefix — scope to one worker, e.g. `prefix: "iii-sandbox/"`.
+- `type`: exact frontmatter `type:` (`index`, `how-to`, `reference`, …).
+- `include_description`: set `false` for a token-light list of just `id` + `title` + `type`.
+
+`directory::skills::index` is the token-light cousin: one block per installed worker — each worker's root overview doc (`/index`), whether or not it declares `type: index`. Each block ends with a `directory::skills::get { id }` call to read the full reference. It truncates if the output gets large (it tells you to call `list` when it does).
+
+## Engine introspection
+
+To learn a single engine function's exact schema, this worker wraps ONE engine call:
+
+### `directory::engine::functions::info`
+A thin proxy to the engine's native `engine::functions::info`. Use it when you can only reach the `directory::` namespace.
+- **Input:** `{ "function_id": "sandbox::create" }` (fully-qualified id, required).
+- **Output:** `function_id`; `worker_name`; `description`; `request_schema` / `response_schema` (JSON Schema or null); `metadata`; `registered_triggers` (each with `id`, `trigger_type`, `config`).
+
+```json
+{
+ "function_id": "sandbox::create",
+ "worker_name": "sandbox",
+ "description": "Boot a sandbox to run untrusted code.",
+ "request_schema": { "type": "object" },
+ "response_schema": null,
+ "metadata": null,
+ "registered_triggers": []
+}
+```
+
+For "what is connected RIGHT NOW?" there is no `directory::` wrapper — call the engine directly:
+- `engine::functions::list` — registered functions.
+- `engine::workers::list` / `engine::workers::info` — workers with an open WebSocket.
+- `engine::triggers::list` / `engine::trigger-types::list` — registered trigger instances and types.
+
+Note: `engine::workers::list` only sees workers with an open WebSocket. Daemon-managed providers (`iii-http`, `iii-cron`, `iii-state`) do NOT open one — list them with `worker::list` from the supervisor daemon and merge by `name`. See [`iii://iii/index`](iii://iii/index).
+
+## Recipe: a worker says a function/trigger is "unknown"
+
+If `engine::functions::info` (or `trigger-types::info`, `workers::info`) says "not found" but you believe the capability exists, the worker's skill bundle is almost certainly not on disk yet. Recover in order:
+
+1. `directory::registry::workers::list { search: "" }` — confirm it exists in the public registry.
+2. `directory::skills::download_from_registry { worker: "" }` — install its bundle. Re-run `directory::skills::index`; the worker now appears.
+3. `directory::skills::get { id: "" }` — read the full reference, including any custom trigger types it ships.
+4. Still missing from `engine::workers::list` but `worker::list` shows it `running: true`? That is the WebSocket-view vs daemon-view split (Rule above) — merge by `name`.
+
+This is the single most common failure when wiring a new worker into an engine.
+
+## Recipe (advanced): calling an HTTP route you registered
+
+> Skip unless you registered an `http` trigger and need to hit the route. This is about the `iii-http` and `sandbox` workers, not the directory.
+
+After `iii.registerTrigger({ type: 'http', http_method, api_path, ... })` returns OK, the route is served by the `iii-http` worker on ITS host/port — not the engine WebSocket port.
+
+**Find the base URL:**
+1. `iii-http` won't show in `engine::workers::list` (no WebSocket). Confirm it is alive with `worker::list` (`running: true`).
+2. Get its port from your engine config's `iii-http: { config: { host, port } }` block (harness default `127.0.0.1:3111`), or from `directory::registry::workers::info { name: "iii-http" }`.
+3. URL = `://:` → default config + `api_path: "/todos"` = `http://127.0.0.1:3111/todos`.
+
+**Make the request — use `web::fetch`, not shell `curl`.** `web::fetch` returns a parsed `{ ok, status, headers, body }` envelope with size/timeout caps and SSRF protection a shell `curl` lacks:
+
+```jsonc
+// agent_trigger { function: "web::fetch", payload: { "url": "http://127.0.0.1:3111/todos" } }
+```
+
+**From INSIDE a sandbox:** `127.0.0.1` is the guest's own loopback, not the host. The sandbox daemon rewrites any env value containing `://localhost:` or `://127.0.0.1:`, but **only at `sandbox::create` time** — so pass the iii-http base in as env when you create the sandbox:
+
+```jsonc
+// sandbox::create
+{
+ "image": "node",
+ "network": true,
+ "env": [
+ "III_ENGINE_URL=ws://127.0.0.1:49134",
+ "III_HTTP_BASE=http://127.0.0.1:3111"
+ ]
+}
+// then read $III_HTTP_BASE inside the guest (it resolves to e.g. http://100.96.0.1:3111)
+```
+
+**Pitfalls:**
+- Guessing a port and calling `127.0.0.1:` from inside a sandbox fails twice — wrong port AND it skips the rewrite.
+- `sandbox::exec` timeouts are capped (~30s) by the agent gateway; use the detached-launch pattern for long probes.
+
+## Registry details
+
+- `registry::workers::list`: pages through published workers. With no `search`, rows order by `total_downloads DESC`; with `search`, by fuzzy similarity. Pass `pagination.next_cursor` back verbatim as `cursor:` for the next page; it is `null` on the last page.
+- Registry rows share `name` / `description` / `version` with `engine::workers::list`, so a parser reading only those keys works against either. The registry view adds publication metadata (`type`, `config`, `supported_targets`, `total_downloads`, `dependencies`, optional `image`); the engine view adds live connection state.
+
+## Skill / prompt id grammar (the precise rules)
+
+- A skill `id` is the file's path under `skills_folder` with `.md` removed (`agent-memory/observe.md` → `agent-memory/observe`).
+- Each `/`-separated segment must match `[a-z0-9_-]{1,64}`; depth is unbounded. Prompt `name` follows the same rule.
+- Title shown for a skill: frontmatter `title:` → first `# H1` in the body → the bare id. Description: the first non-heading paragraph (empty if the file is headings only).
+
+## Related
+
+- [`iii://iii/index`](iii://iii/index) — the engine itself: WebSocket model, functions/triggers, "trust runtime probes over introspection".
+- [`iii://sandbox/index`](iii://sandbox/index) — sandbox deployment, `network: true`, and the loopback rewrite the HTTP recipe relies on.
+- [`iii://web/index`](iii://web/index) — `web::fetch`: the full request/response envelope and the `ok`-vs-`status` rule.

-
-`how_guide` is the **primary** how-to. It's `null` (or omitted) when no

-functions: [directory::prompts::list, directory::prompts::get]
-title: List and read filesystem-backed prompts
----
-
-# When to use
-
-Use `directory::prompts::*` to surface the static, parametric prompt
-templates a worker ships alongside its code. Prompts are the
-slash-command counterpart to the function surface — the *user*
-invokes them (`/send-email`, `/triage`), and the agent renders them
-into a real call.
-
-| Question | Use this |
-|-----------------------------------------------------------|--------------------------------|
-| What prompt templates are available right now? | `directory::prompts::list` |
-| What does this one prompt actually contain? | `directory::prompts::get` |
-
-Prompts are sourced from the same `skills_folder` as skills. Files at
-`//prompts/*.md` with YAML frontmatter declaring
-at least `description` are exposed; everything else is treated as a
-skill body. Re-reads happen on every call — file edits are visible
-immediately, no caching.
-
-The two responses are plain JSON shapes — no MCP envelope, no
-role/messages wrapper — so this worker stays agnostic to MCP and any
-other adapter. Adapters can shape the response on their own side.
-
-# `directory::prompts::list`
-
-## Inputs
-
-```json
-{}
-```
-
-No parameters.
-
-## Outputs
-
-```json
-{
- "prompts": [
- {
- "name": "send-email",
- "description": "Compose and send a transactional email.",
- "modified_at": "2026-05-01T12:34:56+00:00"
- }
- ]
-}
-```
-
-- `name` is the prompt's frontmatter `name`, falling back to the
- file stem (e.g. `send-email.md` → `send-email`). Each name must
- satisfy `[a-z0-9_-]{1,64}`.
-- `description` is the frontmatter `description` (required at scan
- time — files without it are silently skipped).
-- `modified_at` is the file's mtime as RFC 3339.
-
-Rows are sorted lexicographically by `name`.
-
-# `directory::prompts::get`
-
-## Inputs
-
-```json
-{ "name": "send-email" }
-```
-
-`name` is required and must match the same `[a-z0-9_-]{1,64}` shape
-returned by `directory::prompts::list`.
-
-## Outputs
-
-```json
-{
- "name": "send-email",
- "description": "Compose and send a transactional email.",
- "body": "# /send-email\n\nCompose an email…",
- "modified_at": "2026-05-01T12:34:56+00:00"
-}
-```
-
-- `name`, `description`, and `modified_at` mirror the listing row.
-- `body` is the raw markdown body **after** the YAML frontmatter is
- stripped — what the user-facing slash command should render.
-
-The shape mirrors `directory::skills::get` exactly (with `name`
-standing in for that surface's `id`) so a single client struct can
-target either reader.
-
-# Worked example
-
-After `directory::skills::download {worker: "resend"}` (which writes
-both the `index.md` skill body and any `prompts/*.md` prompt files
-under `/resend/`):
-
-```json
-{}
-```
-
-→ `directory::prompts::list` returns one row per prompt the worker
-shipped (e.g. `[{"name": "send-email", "description": "...",
-"modified_at": "..."}]`).
-
-```json
-{ "name": "send-email" }
-```
-
-→ `directory::prompts::get` returns that prompt's body alongside
-the same `name` / `description` / `modified_at` fields.
-
-# Side effects
-
-After every successful `directory::skills::download` that wrote at
-least one prompt markdown, the worker fires
-`directory::prompts::on-change` with payload
-`{ "op": "download", "namespace": "", "source": "repo" | "registry" }`.
-Subscribers (e.g. the `mcp` worker) use this to forward MCP
-`notifications/prompts/list_changed` to their clients without
-re-polling.

-```
-
-You may pass either `version` or `tag`, not both. With neither, the

-
-`worker` / `readme` / `api_reference` come from `GET /w/{slug}?version=…`.
-`skills_tree` comes from a parallel `GET /w/{slug}/skills?version=…`
-call — the worker fans both out concurrently and merges them, dropping
-the markdown `content` and prompt `args_schema` from the skills payload
-(call `directory::skills::download` to materialise bodies on disk).
-
-# Caching
-
-Each unique `(name, version|tag)` pair is cached for
-`registry_cache_ttl_ms` (default 60s). Repeat calls within the TTL
-window don't hit the registry — they return the same merged response
-from in-process memory. To bust the cache, wait out the TTL or call
-with a different version/tag.

-The first three fields (`name`, `description`, `version`) are shared

-registry-only metadata.
-
-`pagination.next_cursor` is opaque — pass it back as `cursor:` to fetch
-the next page. `null` on the last page (with `has_more: false`).
-`page_size` is the server's choice; clients can't override it.
-
-# Caching
-
-Each unique `(search, cursor)` pair is cached for `registry_cache_ttl_ms`
-(default 60s). Repeat calls within the TTL window don't hit the
-registry — they return the same response from in-process memory.
-
-# Worked example
-
-Browse the most-downloaded workers (no search):
-
-```json
-{}
-```
-
-Find every published worker mentioning "memory":
-
-```json
-{ "search": "memory" }
-```
-
-Fetch the next page (using a cursor from a previous call):
-
-```json
-{ "search": "memory", "cursor": "eyJzIjo0Mi4wLCJpZCI6IjBkNTRhMWZmLTJjMjMtNGY4MC05ZTRkLTRmNmVkM2EwYTgxMiJ9" }

-> **Function id:** `directory::skills::download` — pass this to `agent_trigger { function: "directory::skills::download" }` (NOT the skill path you saw in `directory::skills::list`; that's a documentation id, not a callable function id).
-
-# When to use
-
-Call `directory::skills::download` when you want to populate

-(`api.workers.iii.dev`) or from a GitHub repo. This is the **only**

-`directory::prompts::*`) reads from whatever ends up on disk.
-
-Reach for it when:
-
-- You're provisioning a fresh machine and need a worker's bundle pulled
- locally so `directory::skills::get` can serve it.
-- You want to pin a worker's skills to a known semver instead of always
- tracking `tag: "latest"`.
-- You want to vendor an out-of-registry skill bundle from a GitHub repo
- for prototyping.
-
-Re-pulling the same source overwrites files **file-by-file** — siblings
-outside the response set survive, so hand-edited additions stick around
-across re-pulls.
-
-# Inputs
-
-Exactly one source must be specified.
-
-**Source A — GitHub repo:**
-
-```json
-{
- "repo": "https://github.com//",
- "skill": "",
- "branch": "main"
-}
-```
-
-Clones with `git clone --depth 1 --branch ` and copies
-`skills//...` into `//`.
-
-`branch` is optional and defaults to `"main"`. Pass `"master"` (or any
-other branch name) for repos whose default branch is not `main`.
-
-**Source B — workers registry:**
-
-```json
-{
- "worker": "agent-memory",
- "version": "1.2.3"
-}
-```
-
-or
-
-```json
-{
- "worker": "agent-memory",
- "tag": "latest"
-}
-```
-
-or simply:
-
-```json
-{ "worker": "agent-memory" }
-```
-
-`version` and `tag` are mutually exclusive. With neither, the call
-defaults to `tag: "latest"` (matching
-`directory::registry::workers::info`).
-
-# Outputs
-
-```json
-{
- "namespace": "agent-memory",
- "skills_written": ["index.md", "observe.md", "recall.md"],
- "prompts_written": ["summarize.md"],
- "source": { "kind": "registry", "worker": "agent-memory", "tag": "latest" }
-}
-```
-
-For the GitHub source, `source` includes the resolved `branch`:
-
-```json
-{ "kind": "repo", "repo": "...", "skill": "frontend-design", "branch": "main" }
-```
-
-`namespace` is the destination folder under `skills_folder`.
-`skills_written` / `prompts_written` are paths relative to that
-namespace (excluding the `prompts/` segment for prompts).
-
-# Side effects
-
-After every successful download the worker fires:
-
-- `directory::skills::on-change` if at least one skill markdown was
- written, with payload
- `{ "op": "download", "namespace": "", "source": "repo" | "registry" }`.
-- `directory::prompts::on-change` if at least one prompt markdown was
- written (same payload shape).
-
-Subscribers (e.g. the `mcp` worker) use these to forward MCP
-`notifications/list_changed` to their clients without re-polling.
-
-# Worked example
-
-Pin `agent-memory` to a known semver:
-
-```json
-{ "worker": "agent-memory", "version": "1.2.3" }
-```
-
-Pull whatever's tagged `latest` (the default when no version/tag is
-given):
-
-```json
-{ "worker": "agent-memory" }
-```
-

-
-# When to use
-
-Call `directory::skills::get` whenever you need the **body** of one
-skill — the markdown a worker publishes to teach the agent when and
-why to use its functions. It returns the body alongside the same
-`title`, `type`, `description`, and `modified_at` fields each
-`directory::skills::list` row already carries, so the API mirrors
-`directory::prompts::get` (plus `type` lifted from the file's YAML
-frontmatter).
-
-Reach for it when:
-
-- You hit an `iii://...` link inside another skill and need its
- contents inlined.
-- You're building a picker UI that resolved an id from
- `directory::skills::list` and the user selected one row.
-- You want a deeper sub-skill (`iii://resend/email/send`) that wasn't
- inlined into the system-prompt bootstrap (which loads root skills
- only).
-
-There is no batching. Call once per id; consumers that need several
-bodies issue one `get` per id.
-
-# Inputs
-
-```json
-{ "id": "agent-memory/observe" }
-```
-
-`id` is required. It must be the same string `directory::skills::list`
-returned (a path under `skills_folder` with `.md` stripped). Each
-segment must satisfy `[a-z0-9_-]{1,64}` and the depth is unbounded.
-
-For ergonomics the legacy `iii://{id}` link form is also accepted —
-the prefix is stripped before validation:
-
-```json
-{ "id": "iii://agent-memory/observe" }
-```
-
-Any other URI scheme (`https://`, `ftp://`, ...) is rejected.
-
-# Outputs

- "body": "# How to observe\n\n...",
- "modified_at": "2026-05-01T12:34:56+00:00"
-}
-```
-
-- `id` echoes the resolved id (the same string accepted as input,
- with any `iii://` prefix stripped).
-- `title` resolves in this order: YAML frontmatter `title:` (when
- present and non-empty after trim), then the first `# H1` line in
- the body, with the bare `id` as a final fallback.
-- `type` is the YAML frontmatter `type:` field (free-form classifier;
- common values are `index`, `how-to`, `reference`). `null` when the
- file has no frontmatter or omits the key.
-- `description` is the first non-heading paragraph, empty when the
- file has only headings.
-- `body` is the raw markdown post-frontmatter from disk.
-- `modified_at` is the file mtime as RFC 3339 (empty if the FS
- doesn't expose it).
-
-The shape is intentionally close to `directory::prompts::get` (with
-`id` standing in for that surface's `name`); the `type` field is
-unique to skills and reflects the frontmatter classifier authors use
-to tag their files.
-
-# Worked example
-
-The agent loaded a worker skill that links to a deeper sub-skill at
-`iii://resend/email/send`. To inline the linked body:
-

-# When to use
-
-Call `directory::skills::index` when an agent harness needs to know

-pointer the agent can follow with `directory::skills::get` when it
-actually needs the details.
-
-Reach for it when:
-

- prompt to list the available workers so the model can plan which
- one to drill into.
-- You want a copy-paste-ready overview of *workers* (not every skill)
- for a README, changelog, or chat message.
-- You need a stable "what's installed?" snapshot keyed by worker
- rather than by skill id.
-
-Use [`directory::skills::list`](iii://directory/skills/list) instead
-when you need **per-skill rows** (`id`, `title`, `type`, `bytes`,
-`modified_at`) — e.g. for a picker UI, programmatic filtering, or
-anything that wants every skill, not just the worker overviews.
-Use [`directory::skills::get`](iii://directory/skills/get) to fetch
-the full body of any `iii:///index` link surfaced in the response.
-
-# Inputs
-
-```json
-{}
-```
-
-No parameters. The worker re-scans `skills_folder` on every call and
-re-reads each `type: index` overview to populate the description, so
-edits to a worker's `index.md` are visible immediately (same policy
-as `directory::skills::list`).
-
-# Outputs
-
-```json
-{
- "body": "# Skills index\n\n2 worker(s).\n\n## agent-memory\n\nPersistent memory tier for agents.\n\nRead [`iii://agent-memory/index`](iii://agent-memory/index) for the full worker reference.\n\n## iii-directory\n\nEngine introspection, workers registry proxy, and filesystem-backed skill + prompt reader for the iii engine. ...\n\nRead [`iii://iii-directory/index`](iii://iii-directory/index) for the full worker reference.\n",
- "workers_count": 2
-}
-```
-
-- `body` is the rendered markdown document. The harness usually
- pastes this verbatim into a system prompt or message.
-- `workers_count` is the number of worker entries rendered (i.e. the
- count of `type: index` skills surviving the filter). Cheap sanity
- check that doesn't require re-parsing the body.
-
-# Rendering rules
-
-Only skills with frontmatter `type: index` appear in the body — one
-entry per installed worker. Skills of any other type (`how-to`,
-`reference`, untyped, ...) are filtered out. This is important: a
-how-to skill that happens to live at `/index.md` (frontmatter
-`type: how-to`) will NOT be mistaken for a worker overview.
-
-The body always starts with:
-
-```markdown
-# Skills index
-
- worker(s).
-```
-
-Then, for every `type: index` skill (sorted lex by id, same order
-`directory::skills::list` returns):
-
-```markdown
-##
-
-
-
-Read [`iii://`](iii://) for the full worker reference.
-```
-
-- `` follows the same precedence as every other
- `directory::skills::*` response: frontmatter `title:` wins, then the
- first body `# H1`, then the bare `id` as a last resort.
-- The description paragraph is the first non-heading paragraph from
- the worker's `index.md` body (already extracted by the same helper
- `directory::skills::list` uses, so the text matches what a row in
- that listing would carry).
-- When the overview body has no paragraph (heading-only file), the
- description block — and its surrounding blank line — is skipped so
- the section stays compact: `\n## \n\nRead ...`.
-
-There is intentionally no `###`, no per-skill bullets, and no nested
-grouping. If you need that level of detail for one specific worker,
-follow its `iii:///index` link with `directory::skills::get`.
-
-# Worked example
-
-Given a `skills_folder` that contains two workers (`agent-memory`
-with an `index.md` whose frontmatter declares
-`title: agent-memory, type: index` and a one-paragraph overview, plus
-this `iii-directory` worker's own `index.md`), the response body
-looks like:
-
-```markdown
-# Skills index
-
-2 worker(s).
-
-## agent-memory
-
-Persistent memory tier for agents. Records observations and recalls
-them on demand via `agent-memory::observe` and `agent-memory::recall`.
-
-Read [`iii://agent-memory/index`](iii://agent-memory/index) for the full worker reference.
-
-## iii-directory
-
-Engine introspection, workers registry proxy, and filesystem-backed
-skill + prompt reader for the [iii engine](https://github.com/iii-hq/iii).

-split into four sub-namespaces (all MCP-agnostic):
-
-Read [`iii://iii-directory/index`](iii://iii-directory/index) for the full worker reference.
-```
-
-The harness pastes this into the system prompt; when the agent
-decides it needs to call a specific function, it follows the
-matching `iii://...` link with `directory::skills::get` to pull the
-full reference + how-tos.

-# When to use

-Call `directory::skills::list` when you need an enumeration of every

-`skills_folder`. One row per file (recursive `**/*.md`, `prompts/`
-segments excluded), sorted lex by `id`. Each row already carries
-`title` (frontmatter `title:` when present, else the body H1),
-`type` (frontmatter `type:` — e.g. `index`, `how-to`, `reference`),

-Every public function sits under a single `directory::*` namespace,
-split into four sub-namespaces (all MCP-agnostic):
-
-- **Skills** (`directory::skills::*`) — markdown documents under
- `iii://{id}` plus an `iii://directory/skills` index. Use for "when

-- **Engine** (`directory::engine::*`) — read-side enrichment over

- "What's connected to the engine right now?"
-- **Registry** (`directory::registry::*`) — HTTP proxy over
- `api.workers.iii.dev` with the same `workers::{list,info}` shape as

-## How-tos
-
-### `directory::skills::*` — filesystem-backed skill reader
-
-- [`directory::skills::list`](iii://directory/skills/list) — enriched listing of every skill on disk (id, title, type, description, bytes, modified_at). `title` prefers the YAML frontmatter `title:` over the body H1; `type` is lifted from frontmatter `type:` (`null` when absent).
-- [`directory::skills::get`](iii://directory/skills/get) — read one skill body by id (returns the same id/title/type/description/modified_at as `list` plus `body`).
-- [`directory::skills::index`](iii://directory/skills/index) — short markdown index of every installed worker (one `## ` + first paragraph + `read more` link per `type: index` skill); designed for token-light agent bootstrap.
-- [`directory::skills::download`](iii://directory/skills/download) — pull markdown into `skills_folder` from the workers registry or a GitHub repo.
-
-### `directory::prompts::*` — filesystem-backed prompt reader
-
-- [`directory::prompts::*`](iii://directory/prompts) — list and read parametric slash-command templates the *user* invokes; same flat `{ name, description, body, modified_at }` shape `directory::skills::get` uses for skills.
-
-### `directory::engine::*` — what's connected to the engine
-
-- [`directory::engine::functions::list`](iii://directory/engine/functions/list) — list functions registered with the engine; filter by search/prefix/worker.
-- [`directory::engine::functions::info`](iii://directory/engine/functions/info) — inspect one function's schemas, owner, and how-to skill.
-- [`directory::engine::triggers::list`](iii://directory/engine/triggers/list) — list trigger types registered with the engine.
-- [`directory::engine::triggers::info`](iii://directory/engine/triggers/info) — inspect one trigger type's schemas + live instance count.
-- [`directory::engine::registered-triggers::list`](iii://directory/engine/registered-triggers/list) — list registered trigger instances (subscriber rows).
-- [`directory::engine::registered-triggers::info`](iii://directory/engine/registered-triggers/info) — inspect one registered trigger (instance + type + function).
-- [`directory::engine::workers::list`](iii://directory/engine/workers/list) — list workers connected to the engine; shares the core `name` / `description` / `version` fields with `directory::registry::workers::list`.
-- [`directory::engine::workers::info`](iii://directory/engine/workers/info) — inspect one connected worker's full surface.
-
-### `directory::registry::*` — what's published in the public registry

-- [`directory::registry::workers::list`](iii://directory/registry/workers/list) — browse / search published workers in `api.workers.iii.dev`. Cursor-paginated; rows share the core `name` / `description` / `version` fields with `directory::engine::workers::list` and add publication metadata (`type`, `config`, `supported_targets`, `total_downloads`, `dependencies`, optional `image`).
-- [`directory::registry::workers::info`](iii://directory/registry/workers/info) — full registry detail for one worker (envelope + readme + api_reference + skills_tree).

-//! * `directory::engine::functions::info` — single function with schemas, registered triggers, how-to skill

-//! * `directory::engine::workers::list` — list connected workers, filterable
-//! * `directory::engine::workers::info` — worker envelope + its functions + trigger types + registered triggers
-//!
-//! All handlers are thin wrappers around `III::trigger` calls to the
-//! engine introspection endpoints (`engine::functions::list`,
-//! `engine::workers::list`, `engine::trigger-types::list`,
-//! `engine::triggers::list`) plus filesystem-backed how-to skill discovery

+//!
+//! ```text
+//! D110 not_found: skill "database/query" does not exist. \
+//! Did you mean: database/iii-database/query, database/index. \
+//! Next: call directory::skills::list to browse skill ids; \
+//! or directory::skills::index to see the per-worker overview.
+//! ```
