Implement work described in a specification or set of tickets, using test-first development where agreed. Run type checks and tests throughout, review the completed changes, and commit the work to the current branch.
基于 spec 或 ticket 集合实现一段工作。
Review the instructions the agent will receive before you install.
实现用户在 spec 或 tickets 中描述的工作。
尽可能在预先约定好的 seams 上使用 /tdd。
定期运行 typechecking，定期运行单个测试文件，并在最后运行完整测试套件。
完成后，使用 /code-review 审查这次工作。
把工作提交到当前 branch。

Find the right skill and sequence for your current development task, from shaping an idea to implementation, debugging, and review. The guide also explains when to prototype, prepare specifications, or move work into a fresh session.
Summarize the current conversation and launch a fresh background agent to continue the work. The handoff includes references to existing artifacts and suggested skills, removes sensitive information, and can emphasize the next session’s intended focus.
Review changes from a chosen Git reference against both project coding standards and issue or specification requirements. Separate parallel reviews report rule violations, possible design problems, missing requirements, and changes beyond the intended scope.
Design modules that expose simple interfaces while hiding substantial behavior. Use shared terms and principles to assess interface complexity, decide where behavior can be swapped, and organize code so callers and tests use the same interface.
Diagnose difficult bugs and performance regressions by first building a repeatable check for the exact symptom. Minimize the reproduction, test ranked hypotheses, apply a fix, and verify the original scenario with regression tests where suitable.
Clarify project terminology and the relationships between business concepts. Check definitions against concrete scenarios and code, update GLOSSARY.md as terms are agreed, and record significant design decisions with their trade-offs when the stated criteria are met.
