Package map for the loop-hygiene guard family: the advisory repeat-tool reminder and the per-call tool-call timeout policy, for users and maintainers choosing or composing the guards.	package-group

guard/ — loop-hygiene guard family

English | 中文

Summary

The guard/ group keeps the agent loop productive by watching for two common failure patterns. repeat-tool-reminder notices when the model repeats the exact same tool call and reminds it to change approach or finish, so a stuck loop stops burning time and tokens. timeout-policy puts a time limit on tool calls that declare one, so a hung call returns a clear timed-out error to the model instead of stalling the session. Both ship enabled in the dsh base bundle; a composition can tune or remove them.
