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 <x>. Showing <y> 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: "<name>" }`, 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: "<name>" }`. 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/<org>/<repo>", skill: "<folder>" }`. `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 `<skills_folder>/<ns>/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: "<worker>" }` 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 (`<ns>/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: "<worker-name>" }` — confirm it exists in the public registry. +2. `directory::skills::download_from_registry { worker: "<worker-name>" }` — install its bundle. Re-run `directory::skills::index`; the worker now appears. +3. `directory::skills::get { id: "<worker-name>" }` — 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 = `<scheme>://<host>:<port><api_path>` → 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:<port>` or `://127.0.0.1:<port>`, 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:<port>` 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.
