The envelope matches the chats/assets list shape. Pagination is cursor-based: pass the previous response's `last_id` as `after_id` to fetch the next page. `has_more: false` means the end. ## OpenAPI ````yaml /openapi.yaml get /v1/skills openapi: 3.0.3 info: title: Chief Public API version: 1.0.0 contact: name: Chief Support url: https://chief.bot description: | Chief's public REST API for programmatic access to chats and assets. All endpoints are authenticated with a Personal Access Token (PAT) sent in the `X-API-Key` header. PATs are minted out-of-band from the Chief settings UI. All endpoints that touch project-scoped resources require the `X-Project-Id` header. Missing or invalid project IDs respond with HTTP 400 and the error code `publicapi.tenancy.project.missing`. ## Error envelope Every error response uses the same JSON envelope: ```json { "code": "publicapi.auth.invalid", "humane": "The provided API key is invalid or has been revoked.", "statusCode": 401 } ``` `code` is a stable, dotted, lowercase identifier suitable for client-side i18n and analytics. `humane` is plain English safe to surface to end users. `statusCode` mirrors the HTTP status. ## Chat workflow — kickoff + poll Chats are asynchronous in v1. Callers need to poll the per-message endpoint until the content they need is present. 1. `POST /v1/chats` with `{prompt}`. The server kicks off the workflow and returns `{chat_id, message_id, created_at}` immediately. `message_id` is the message you'll poll. 2. `POST /v1/chats/{chat_id}/messages` with `{prompt}` to continue an existing chat — appends a new turn and returns `{message_id, created_at}`. 3. `GET /v1/chats/{chat_id}/messages/{message_id}` to read the message. While the workflow is still writing, `prompt` and `response` are omitted; once written they're present. Treat the appearance of `response` as the signal that the assistant has produced output. 4. `GET /v1/chats/{chat_id}` returns chat-level metadata only (`modified_at`). It does not carry messages. 5. `GET /v1/chats/{chat_id}/messages` lists every message's id + `created_at` (no content); clients fetch one message at a time via `GET /v1/chats/{chat_id}/messages/{mid}` for the prompt + response body. ## Asset workflow — three-step upload Assets are uploaded directly to blob storage via a signed URL. The flow is: 1. `POST /v1/assets` with `{filename, mime_type}`, optionally including the hex-encoded `md5` of the file. When `md5` matches content already in the project the server returns `200` with `already_exists: true` and no upload URL — skip to fetching the asset. Otherwise it returns `201` with `{asset_id, upload_url, upload_method:"PUT", upload_headers, expires_at}`. 2. `PUT` the file bytes to `upload_url`, applying every header in `upload_headers` verbatim. The URL is valid until `expires_at`. 3. `POST /v1/assets/{asset_id}/complete` with an empty body to hand the asset off to the ingest pipeline. The server reads the uploaded object's size and MD5 from blob storage at this step. The response carries the current `AssetResponse`; clients poll until `status` is `ready` or `failed`. servers: - url: '{baseUrl}' description: Chief variables: baseUrl: default: https://api.storytell.ai description: Base URL of the deployment serving the API. security: - apiKey: [] tags: - name: Chats description: Public chat lifecycle — kickoff, list, fetch. - name: Assets description: Public asset upload + ingest lifecycle. - name: Labels description: Public label CRUD and asset-label attachment. - name: Actions description: Public action CRUD plus enable/disable. - name: Sessions description: Public recording-session listing and CRUD. - name: Skills description: Public skill CRUD plus enable/disable. - name: Memories description: Public memory CRUD. - name: Projects description: Public project create/edit, membership, and invitations. paths: /v1/skills: get: tags: - Skills summary: List Skills description: | Returns skills visible in the focused project — system, project, and user scopes the caller can access.
