Design a target architecture for a new system — module boundaries, dependency rules, seams, and build order — from its requirements. Reports a blueprint; changes nothing.
Analyze an existing codebase's architecture and produce a sequenced refactoring plan — assess module boundaries, dependency structure, and layering, then lay out ordered, risk-tagged steps. Language-agnostic. Reports a plan; changes nothing.
Turn a goal or another command's output into an ordered task roadmap.
Find the root cause of a failure with the scientific method — reproduce, isolate, fix, then prove it.
Interview the user relentlessly about a plan or design until reaching shared understanding.
Run an extremely strict maintainability + single-source-of-truth review of code changes — abstraction quality, file sprawl, spaghetti-condition growth, and duplicate/competing implementations. Reports findings by default; `--fix` applies the mechanical, unambiguous ones — structural/code-judo restructurings rest on judgment and stay reported.
Drive implementation with tests, one vertical slice at a time.
Activate pragmatic testing mode for this session.
