[UlricQin]

Doc Review — 2026-07-22

Mode: focused user-facing sync
Findings: 3 user-facing changes

Changes

Finding	Type	Module	Doc	Action
F001	stale_content	Tool availability	zh/en target overview and configuration	Removed the retired Script Tool configuration and references
F002	missing_coverage	Shell approval	zh/en Agent installation and configuration	Added the root-only workflow for approving an occasionally blocked command, including the 10-second batch decision and session lifecycle
F003	config_drift	Configuration reload	zh/en configuration and verification	Explained that tool-switch changes take effect after SIGHUP without an Agent restart

Implementation-level whitelist rules, parser limits, output shapes, Catalog protocol details, and service runtime-directory behavior are intentionally omitted because they are not user workflows.

Review checklist

• Verify commands and configuration names match current behavior
• Keep content focused on user actions and observable outcomes
• Keep Chinese and English content aligned
• Run mint broken-links
• Run repository unit tests and git diff --check

Mapping warnings

None.

Skipped

Backend-only implementation details that do not change how users install, configure, approve, or reload the Agent.
