Guides

Common MCP Server Failure Modes and How to Fix Them · guide
A runtime playbook for the two MCP server failure modes with no dedicated deep-dive elsewhere: unrecoverable state after a mid-call crash, and malformed or hallucinated tool calls that reach the handler despite upstream validation.
How to Make AI Agent Retries Idempotent · guide
A deep-dive on retrying agent tool calls safely: the transient-vs-terminal decision, why an agent side effect can fire before a failure signal reaches the caller, idempotency-key mechanics (run ID + step index), the unknown-outcome edge case, and where idempotency keys do not reach.
