statamic-ai-gateway（静态 AI 网关）

AI Gateway — Agent Skill

Manage Statamic content through a safe, authenticated tool execution gateway. Supports managing multiple Statamic sites from a single agent installation.

Before first use, follow the setup in INSTALL.md. For the endpoint contract, see references/api.md.

Site Registry

Credentials are stored in ~/.config/ai-gateway/sites.json (override with AI_GATEWAY_SITES_CONFIG).

{
  "sites": {
    "marketing": { "base_url": "https://marketing.example.com", "token": "token-aaa..." },
    "docs": { "base_url": "https://docs.example.com", "token": "token-bbb..." }
  }
}

Look up base_url and token by site name before every request.

Endpoints

All requests require Authorization: Bearer {token}.

Discovery-First Workflow

Do not guess tool arguments. Always discover before executing:

1. GET /capabilities — see which tools are enabled on this site
2. GET /capabilities/{tool.name} — get the argument schema, validation rules, example request/response, allowed targets, denied fields, and behavioral notes for that tool
3. Use the returned information to construct your /execute request

This is the primary way to learn how to use any tool. The capabilities endpoints are the source of truth.

Request Envelope

{
    "tool": "tool.name",
    "arguments": { },
    "request_id": "optional-tracking-id",
    "idempotency_key": "optional-dedup-key",
    "confirmation_token": "optional-if-confirming"
}

Response Envelope

Success: { "ok": true, "tool": "...", "result": { ... }, "meta": { ... } }

Error: { "ok": false, "tool": "...", "error": { "code": "...", "message": "..." }, "meta": { ... } }

Rules

⛔ CRITICAL — Structured field values are READ-ONLY structures. Bard, Replicator, Grid, and similar fields store values as deeply nested ProseMirror/TipTap JSON. When reading these back from entry.get or global.get, you will see arrays of node objects with type, attrs, content, and marks keys. You MUST NOT alter the structure. Never add, remove, reorder, or rename nodes, attributes, or marks. You may only change the literal text strings inside leaf nodes — nothing else. To update a rich-text field: (1) fetch with entry.get/global.get, (2) change only text values, (3) send back structurally identical. Violating this corrupts content.

1. Look up base_url and token from sites.json before every request.
2. Discover before executing. Call /capabilities then /capabilities/{tool} before using any tool for the first time on a site.
3. Only call tools where enabled: true. Only target allowlisted resources. forbidden means off-limits.
4. data must be a JSON object, never an array or string. Don't send unknown argument keys.
5. Prefer entry.upsert over entry.create — safer and idempotent.
6. navigation.update is a full tree replacement. Always fetch with navigation.get first.
7. Confirmation-gated tools require user approval. If requires_confirmation: true in capabilities: (1) send the request, (2) receive confirmation_required with a token, (3) show the user the operation_summary and ask permission, (4) only if approved, resend with confirmation_token. Never auto-confirm.
8. If rate_limited, back off and retry.
9. Include the site name in request_id (e.g. marketing:upsert-about).
10. After bulk content changes, consider warming caches: stache.warm rebuilds content indexes, static.warm regenerates static pages.
