生成一份可审查的、带有文件引用的实施计划，作为执行前的合同。用于风险操作、架构变更、迁移、多文件编辑等情况。

Activation gate

Use if:

Multi-file changes, migrations, security/perf sensitive work, or irreversible ops.

If requirements are unclear or acceptance criteria are missing: ask 2–5 clarifying questions (scope, constraints, verify commands) before drafting the plan. Do not assume.
Define objective + acceptance criteria (testable).
Enumerate touched areas: BE/FE/DB/config/CI/CD/infra (or explicitly “NOT touched”).
Identify dependencies (APIs, flags, secrets, external services).
Provide ordered steps with file paths and validation commands.
Stop: wait for user approval (unless user asked “just do it”).
