Entry point for new users — guides through initialization, architecture review, and cleanup. Use when the user first opens this project or says "开始" / "初始化" / "怎么用".
Garbage Collection Agent — 定期扫描项目健康状态，检测文档/代码一致性漂移，自动发起修复提案。
Independently verifies whether a completed task meets its defined goal conditions. Implements maker/checker separation — the agent that wrote the code does not grade its own work. Use after task execution to validate completion before marking done.
Reviews technical decisions before implementation. Detects outdated or suboptimal approaches by searching current best practices. Use when the user asks to implement something using a specific tool, library, or methodology.
Initialize this project with the Harness Engineering starter template. Detects project language, installs dependencies, and updates CLAUDE.md placeholders. Use when the user wants to set up or reset the Harness configuration.
Switch Harness workflow mode (full/hotfix/tweak) and development phase (design/build/fix). Use when the user wants to change the current working mode or phase.
