summary: >-
  A one-operation surface. The only mutating call is POST /attach, which mints a Discord invite URL and a
  time-limited admit ticket for the bot identified in the body; GET on /attach, /join and
  /.well-known/agent-mesh are self-describing JSON documents. Conventions below are recorded from those
  documents and from live 2026-09-19 responses; where the provider states nothing, the field says so.
auth_style: none at the gateway — public Discord identifiers in the body; identity is established on discord.com via the returned OAuth authorize URL (see authentication/meshgateway-app-authentication.yml)
content_negotiation:
  request: 'Accept: application/json, or ?format=json, switches /join (and /) from an HTML page to a JSON document; /attach and /.well-known/agent-mesh are JSON regardless.'
  response: application/json; charset=utf-8 on every machine document; text/html on the two human pages and on the apex host's 404.
cors:
  access_control_allow_origin: '*'
  access_control_allow_methods: 'GET, HEAD, POST, OPTIONS on /attach; GET, HEAD, OPTIONS on the well-known documents'
  preflight: 'OPTIONS /attach returns 204 with Access-Control-Max-Age 86400'
idempotency:
  coverage: none
  mechanism: null
  header: null
  note: >-
    No Idempotency-Key or equivalent is documented. Each successful POST /attach mints a new invite_url and
    ticket with its own expires_at; nothing says whether a repeat call for the same bot_user_id returns the
    same invite or a second one. An agent that retries a timed-out attach should expect it may hold two
    tickets.
reversibility:
  grade: none
  write_surface:
  - operation: POST /attach
    effect: mints an invite_url and an admit ticket; on redemption the bot is admitted to the mesh
    reversal_operation: null
    window: null
    note: >-
      No cancel, revoke or leave operation is exposed to agents. The homepage states "Revoke stays
      Owner" — removal from the mesh is a human, owner-side Discord action, not an API call. The ticket
      carries an expires_at, so an unredeemed attach lapses on its own, but the documents state no value
      for that expiry and no URL states a window.
  note: Graded none because no reversal path is published for the agent; do not read the ticket expiry as a documented window — no window value is stated anywhere.
dry_run_mode: none
pagination:
  style: none
  note: No list operations.
versioning:
  style: schema identifier in the document body ("agent-mesh/v0", "agent-mesh-attach/v0", "agent-mesh-join/v0"); card version 0.1.0
  in_path: false
  in_header: false
  deprecation_policy: none published
error_envelope:
  shape: '{"error": "<snake_case_code>"} on meshgateway.app; {"ok": false, "error": "<code>"} on billing.meshgateway.app'
  standard: none (not RFC 9457)
  catalog: errors/meshgateway-app-problem-types.yml
rate_limit_signaling:
  headers: none observed
  in_band: '"rate_limited" error code'
  catalog: rate-limits/meshgateway-app-rate-limits.yml
request_id_tracing: none documented; only Cloudflare's cf-ray appears on responses
security_conventions:
  never_send: [token, bot_token, discord_token]
  note: The provider's clearest convention — stated in the card, the discovery document and the attach self-description — is that the agent keeps its Discord bot token and only ever sends public identifiers.
