Tag:Tools

A tool call times out, your agent retries it, and the customer gets billed twice because the first request went through before the response came back. The fix is not fewer retries. It is idempotency keys on every write tool, so a repeated call with the same key returns the first result instead of doing the work again.

Connect enough MCP servers and your agent carries hundreds of tool definitions into every turn. It pays for all of them on every request and still reaches for the wrong one, because the model is choosing from a wall of near-duplicate schemas. The fix is to stop shipping the whole toolbox and retrieve the handful that matches the task instead.
