directory::registry::workers::info

Function

Fetch full registry metadata for one worker: worker envelope (same shape as directory::registry::workers::list rows and directory::engine::workers::info), readme, full API reference (functions + triggers schemas), and tree of skill/prompt file paths. Pass either `version` or `tag` (defaults to tag="latest"). Results are cached for `registry_cache_ttl_ms`.

Request
  • namestringrequired

    Worker name in the registry (e.g. `"resend"`).

  • tagstring
  • versionstring

    Mutually exclusive with `tag`. If neither is provided we fall back to `tag: "latest"`.

Request
  • uristring

    A single skill resource to read. Either a full `iii://` URI or a bare skill path (the id returned by `directory::skills::list`, e.g. `"directory/skills/list"`) which is auto-prefixed with `iii://`.

    One or more skill resources to read in order. Same shape rules as `uri`. When both `uri` and `uris` are provided, `uris` wins (matches the TS reference implementation).

Response
valuestring

directory::engine::workers::info

Function

Worker envelope plus the lists of functions, trigger types, and registered triggers it owns. The `worker` field has the same shape as directory::registry::workers::info so callers can switch between local + registry surfaces with the same parser.

Function

Download skills + prompts into skills_folder. Pass {repo, skill, branch?} to clone a single skill folder from a GitHub repo (git clone --depth 1 --branch <branch>; branch defaults to "main"), or {worker, version?|tag?} to pull from the workers registry (defaults to tag="latest" when neither version nor tag is given). Files in the destination namespace are overwritten file-by-file.

directory::registry::workers::list

Function

Request
  • limitinteger· uint32min 0

    Max results to return. Defaults to 20; capped at 100.

  • searchstring

    Free-text query forwarded to the registry as `?q=…`. Required — the public registry doesn't support an unscoped browse endpoint.

Request
  • prefixstring

    Exact prefix match on `function_id` (e.g. `"mem::"`).

    Case-insensitive substring match against `function_id` and `description`.

    Exact worker-name match (the worker that registered the function).

Response
  • functionsobject[]required
    • descriptionstring
    • function_idstringrequired
    • worker_namestring

      Worker that registered it (resolved via `WorkerInfo.functions[]`), or the first `::` segment of `function_id` as fallback.

Function

Full detail for one trigger type: configuration schema, return schema, owning worker, and current instance count.

Request
  • idstringrequired
Response
  • configuration_schemaunknown

    SDK 0.11.3 surfaces a single `trigger_request_format` that doubles as the per-instance configuration shape; expose it explicitly so callers don't have to know the alias.
