Agent roles catalog

This directory is data, not application code. It holds the content of an "agent roles catalog": reusable agent role definitions (system prompts plus a little metadata), grouped into bundles and translated into one or more languages. A separate server reads these files and serves them; nothing here is executable application logic except the validation script.

File layout

agent-roles-catalog/
  index.yaml                  # the catalog manifest: bundles, languages, role versions
  bundles/
    <bundle-id>/
      <lang>.yaml             # one file per declared language (e.g. ru.yaml, en.yaml)
  scripts/
    check.mjs                 # validates the catalog (uses the `yaml` parser)
    content-hashes.json       # check artifact: per-role content-hash lock (NOT served)
  package.json                # defines the `check` script
  README.md

The content files are YAML so the long instructions system prompt can be stored as a literal block scalar (|-): edits show up as line-by-line diffs and the prompt is editable as plain multi-line text instead of a single escaped JSON string. The content-hashes.json lockfile under scripts/ stays JSON — it is a check artifact, never served.

Currently shipped bundles:

• editorial — the editorial suite (structural-editor, line-editor, fact-checker, proofreader, narrator), languages ru, en.
• research — a single researcher role, languages ru, en.

How it's served

The server does not bundle this data; it reads it at request time from a single configured location, the AI_AGENT_ROLES_CATALOG_URL env var (EnvironmentService.getAiAgentRolesCatalogSource()), an http(s):// base URL to the catalog's raw files. The server fetches <base>/index.yaml for the manifest and <base>/bundles/<bundle-id>/<lang>.yaml for each opened bundle file (REMOTE only).

That base URL is provided as a per-branch default in the Docker image (set in CI: a develop build points at the develop raw URL, a release build at the main raw URL) and can be overridden at runtime via the AI_AGENT_ROLES_CATALOG_URL env var. Local-filesystem sources are no longer supported; if the value is unset the catalog is unavailable.

The fetched YAML is parsed with a safe, JSON-compatible schema and re-validated server-side (the catalog is treated as untrusted input). See .env.example for the variable and the CHANGELOG for the rollout.

index.yaml schema

schemaVersion: 1
bundles:
  - id: editorial # unique bundle id; matches bundles/<id>/
    name: # localized display name
      ru: "..."
      en: "..."
    description:
      ru: "..."
      en: "..."
    languages: # which <lang>.yaml files must exist
      - ru
      - en
    roles:
      - slug: structural-editor
        version: 1
      # ...

version lives here, in index.yaml, per role. Bump it whenever a role's content (instructions, name, description, etc.) changes, so consumers can detect updates.

Bundle (<lang>.yaml) schema

schemaVersion: 1
language: ru
roles:
  - slug: structural-editor # REQUIRED, unique across the whole catalog
    emoji: "🧱"
    name: "..." # REQUIRED, localized
    description: "..." # localized
    instructions: |- # REQUIRED, the system prompt, localized (literal block scalar)
      First line of the prompt.
      Second line.
    autoStart: true # whether the role starts working immediately
    launchMessage: "..." # first message sent on launch (or null)

Keep instructions as a literal block scalar (|-, chomp — no trailing newline) so the resolved prompt is byte-for-byte what you typed and diffs stay line-by-line.

Notes:

• modelConfig is intentionally absent; the server treats an absent modelConfig as null.
• A role's slug, emoji, and autoStart are identical across all language files of the same bundle. Only name, description, instructions, and launchMessage are translated.

Slug uniqueness

Every slug must be UNIQUE ACROSS THE WHOLE CATALOG, not just within a bundle. A slug appears once per language file of its bundle (same slug in ru.yaml and en.yaml), but no two different bundles may share a slug. scripts/check.mjs enforces this.

How to add things

Add a role to an existing bundle

1. Add an entry to that bundle's roles[] in index.yaml with a new unique slug and version: 1.
2. Add a role object with the same slug to every <lang>.yaml of the bundle, translating name, description, instructions, and launchMessage.
3. Run the check (see below).

Add a bundle

1. Add a bundle object to index.yaml (id, name, description, languages, roles).
2. Create bundles/<id>/<lang>.yaml for each declared language, with one role object per roles[] entry.
3. Run the check.

Add a language to a bundle

1. Add the language code to that bundle's languages[] in index.yaml.
2. Create bundles/<id>/<lang>.yaml containing every role of the bundle, translated.
3. Run the check.

Change a role's content

Edit the role in the relevant <lang>.yaml file(s) and bump that role's version in index.yaml. Then run node scripts/check.mjs --update-hashes to refresh the content-hash lock (scripts/content-hashes.json). check.mjs now fails if a role's content changed but its version was not bumped, so this step is mandatory — the lock can only be refreshed after the bump.

Validating

From this directory:

node scripts/check.mjs   # or: npm run check

It fails (exit code 1) if any slug is duplicated across the catalog, if a bundle's index roles[] don't match the slugs present in each language file, if a declared language file is missing, or if any role is missing a required field (slug, name, instructions). It prints OK on success.

Content-hash guard

check.mjs also guards against changing a role's content without bumping its version. It keeps a lockfile, scripts/content-hashes.json, mapping each role slug to { version, hash }, where hash is a SHA-256 over the role's content fields (emoji, autoStart, name, description, instructions, launchMessage) across all of its language files, in a deterministic canonical form. This lockfile is a check artifact only — the server fetches only index.yaml and the bundle <lang>.yaml files, never this file, so it has no effect on the served catalog or its schema.

On a normal run, for every role the check recomputes the hash and compares it against the lock:

• content unchanged and versions agree → OK;
• content changed but version not bumped above the lock → error asking you to bump and refresh;
• content changed and version bumped → error asking you to record it by refreshing the lock;
• role missing from the lock, or a lock entry for a role that no longer exists → error asking you to refresh.

Refresh the lock with:

node scripts/check.mjs --update-hashes   # alias: --fix

This recomputes the lock from the current catalog, prunes entries for removed roles, and prints what changed — but it refuses to write (exit 1) if any role's content changed while its index.yaml version was not bumped, so the version bump is always enforced first. The check also requires every index.yaml role to carry a finite numeric version (the server requires the same).

Known, accepted limitation: a deliberate prune-then-readd of a slug (remove the role and run --update-hashes, then re-add it with changed content at the same version) is not caught, because a brand-new slug has no lock baseline to enforce a bump against.
