Find gaps and needless work in implementation plans.
Checks an implementation plan against the original request and produces a separate report of gaps, unnecessary complexity, and risky assumptions.
When to use it
Use when reviewing a plan or design proposal and the user wants a standalone audit without changing the source.
Give it a plan file and the original user request; it writes a separate audit report, asking for clarification when the baseline or important assumptions are unresolved.
