Errors
| Code | Name | Cause | Remediation |
|---|
-32600 | Invalid request | Malformed JSON-RPC envelope | Check method, jsonrpc, and id fields |
-32602 | Invalid params | Missing required field or enum value out of range | Validate against the input schema before calling |
-32001 | Unauthorized | Missing or expired grant token | Refresh via agent.grant.refresh |
-32002 | Policy denied | Grant missing agent:budget:create scope | Issue a new grant with the required scope |
-32004 | Rate limited | Too many saga starts in a short window | Back off by retry_after_seconds in the error data |
-32005 | Vault contention | Parent vault already involved in another saga | Retry with exponential backoff |
-32603 | Internal error | Saga step failed; partial state will be reaped within 10 min | Retry with the same idempotency_key |
