grill-with-docs
围绕这个计划的每个方面持续追问我,直到我们达成共同理解。沿着 design tree 的每个分支往下走,逐一解决决策之间的依赖。对每个问题,都提供你推荐的答案。
一次只问一个问题,并等待我对每个问题的反馈后再继续。
如果某个问题可以通过探索 codebase 来回答,就去探索 codebase,而不是问我。
Domain awareness
探索 codebase 时,也查找现有文档:
File structure
大多数 repos 只有一个 context:
/
├── CONTEXT.md
├── docs/
│ └── adr/
│ ├── 0001-event-sourced-orders.md
│ └── 0002-postgres-for-write-model.md
└── src/
如果根目录存在 CONTEXT-MAP.md,说明 repo 有多个 contexts。这个 map 指向每个 context 的位置:
/
├── CONTEXT-MAP.md
├── docs/
│ └── adr/ ← system-wide decisions
├── src/
│ ├── ordering/
│ │ ├── CONTEXT.md
│ │ └── docs/adr/ ← context-specific decisions
│ └── billing/
│ ├── CONTEXT.md
│ └── docs/adr/
懒创建文件:只有在有内容可写时才创建。如果没有 CONTEXT.md,在第一个 term 被解决时创建。如果没有 docs/adr/,在第一个 ADR 需要时创建。
During the session
Challenge against the glossary
当用户使用的 term 与 CONTEXT.md 中的现有语言冲突时,立即指出。“Your glossary defines 'cancellation' as X, but you seem to mean Y — which is it?”
Sharpen fuzzy language
当用户使用含糊或 overloaded terms 时,提出一个精确的 canonical term。“You're saying 'account' — do you mean the Customer or the User? Those are different things.”
Discuss concrete scenarios
讨论 domain relationships 时,用具体场景做 stress-test。发明能探测 edge cases 的场景,迫使用户精确说明概念之间的边界。
Cross-reference with code
当用户说明某件事如何工作时,检查代码是否一致。如果发现矛盾,指出来:“Your code cancels entire Orders, but you just said partial cancellation is possible — which is right?”
Update CONTEXT.md inline
当一个 term 被解决时,立即更新 CONTEXT.md。不要攒到最后;随着发生就捕获。使用 CONTEXT-FORMAT.md 中的格式。
不要把 CONTEXT.md 和实现细节耦合。只包含对 domain experts 有意义的 terms。
Offer ADRs sparingly
只有以下三点全部为真时,才提议创建 ADR:
- Hard to reverse — 之后改主意的成本有意义
- Surprising without context — 未来读者会疑惑“为什么这样做?”
- The result of a real trade-off — 确实有真实替代方案,并且你基于具体原因选择了一个
如果三者缺一,就跳过 ADR。使用 ADR-FORMAT.md 中的格式。

grill-me
围绕 plan 或 design 持续 interview user,直到达成 shared understanding,并逐一解决 decision tree 的每个分支。Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me".
17tdd
使用 red-green-refactor loop 做 test-driven development。Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.
16zoom-out
让 agent zoom out,并给出更广的 context 或更高层 perspective。Use when you're unfamiliar with a section of code or need to understand how it fits into the bigger picture.
16diagnose
面向棘手 bug 和性能回退的纪律化 diagnosis loop。Reproduce → minimise → hypothesise → instrument → fix → regression-test. Use when user says "diagnose this" / "debug this", reports a bug, says something is broken/throwing/failing, or describes a performance regression.
16to-issues
使用 tracer-bullet vertical slices,把 plan、spec 或 PRD 拆成项目 issue tracker 上可独立领取的 issues。Use when user wants to convert a plan into issues, create implementation tickets, or break down work into issues.
