Limits and quotas

Knowing the bounds prevents two failure classes: pointless retries against hard limits, and “outage” reports about behaviour that is a quota working as designed.

Tokens and grants

Limit	Value	Notes
Agent token lifetime	1–365 days (default 90)	Set at mint; the token cannot extend itself
Tokens per agent identity	Effectively one	Minting with revoke_prior (default) kills all prior tokens immediately
Write scope	Granted contract pool only	Default-deny; publish capability withheld unless explicitly granted
Task/defect tools	Global manage_task grant	Separate axis from contract grants

Request limits (read surfaces)

Surface	Limit
GET /api/v1/errors	limit 1–500 (default 100), newest first
Chat archive search	limit 1–500, since_days 1–365
Board list tools (MCP)	limit default 50

Requests beyond a range are rejected with a validation error — lower the parameter instead of retrying.

Publish and pipeline execution

• Synchronous publish calls have a hard timeout (on the order of minutes, not seconds — site builds are slow). Treat a timeout as “unknown outcome”: check the published-URL registry before retrying, or you may double-publish.
• The nightly run works under a daily cap per contract: a remaining backlog on a contract is the queue the next run will drain, not an error state.
• Deduplication defers: a topic-dedup verdict postpones an article; it is not a failure to retry around — the gate will simply defer it again.

MCP session limits

• Sessions do not survive a platform deploy; reconnect with a fresh handshake (details).
• Plain GET /mcp/ returns 406 by design — the endpoint speaks JSON-RPC, not HTML.

Idempotency

Write endpoints accept an Idempotency-Key header (UUID). Send one on every write; a retried request with the same key is safe. This is the sanctioned retry mechanism — not resubmission loops.
