A timeout does not prove the server failed. The agent added an automatic retry to a POST on timeout, and the first request had already committed, so the second created a duplicate. Retry logic belongs on idempotent calls, or it needs an idempotency key.

Read articleYou run the failing command by hand, watch it pass, declare done, and merge. Three months later the same path breaks because nobody turned that manual repro into a test that stays in the suite.

Read articleQuick answer: An MCP tool with a loose input schema — everything typed as a string, required fields left unmarked, or a catch-all object — pushes validation to runtime and invites the
