  note: >-
    Non-destructive additions only. Nothing in the provider's served spec is altered or removed;
    every action below adds information this catalog established by probing (the MCP binding, the
    error envelope, the agent-facing descriptors) or that the provider publishes elsewhere but did
    not put in the contract (external docs, contact, licence URL, explicit no-auth security).
actions:
- target: $.info
  description: Add the provider's own agent reference as externalDocs and record the licence identifier's home.
  update:
    contact:
      name: FluentEDI
      url: https://fluentedi.com/
    x-agent-reference: https://fluentedi.com/llms-full.txt
    x-privacy: https://fluentedi.com/privacy
- target: $
  description: The served spec has no externalDocs; point agents at the llms.txt the api-catalog declares as service-doc.
  update:
    externalDocs:
      description: FluentEDI agent reference - every tool, parameter and worked example
      url: https://fluentedi.com/llms.txt
- target: $
  description: Make the absence of authentication explicit in the contract rather than implicit in the absence of securitySchemes.
  update:
    security: []
    x-authentication:
      required: false
      type: none
      declared_at:
      - https://fluentedi.com/.well-known/ai
      - https://fluentedi.com/.well-known/ai-plugin.json
      - https://fluentedi.com/.well-known/mcp.json
- target: $
  description: Record the companion agent surfaces the contract does not mention.
  update:
    x-surfaces:
      mcp:
        endpoint: https://fluentedi.com/mcp
        transport: streamable-http
        server_card: https://fluentedi.com/.well-known/mcp/server-card.json
        registry: com.fluentedi/tools
        tools_listed: 19

      recipes: https://fluentedi.com/recipes.json
- target: $
  description: Document the response and error envelope shared by all 99 operations, which the spec describes only per-operation.
  update:
    x-response-envelope:
      success: '{ "ok": true, "tool": "<name>", "result": { ... } }'
      failure: '{ "ok": false, "tool": "<name>", "error": { "code", "message", "details" }, "parameters": <JSON Schema>, "working_examples": [...], "documentation": "..." }'
      error_codes: [invalid_input, unknown_tool, too_many_calls, method_not_allowed]
      note: A failed call returns the tool's full parameter schema and working example URLs, so recovery needs no documentation fetch.
    x-idempotency:
      idempotent: true
      mechanism: intrinsic - every operation is read-only and stateless
    x-reversibility:
      applicable: false
      reason: no write surface
