architecture-investigation

Run an architecture investigation end-to-end through the eight harness skills. Enforces two hard stops with explicit user approval via AskUserQuestion. Never skips grilling.

Relentlessly interview the user about an architecture investigation until scope, drivers, methodology, and deliverables are 100% concrete. MUST use AskUserQuestion for every question, multiple-choice only, with a recommended answer. Minimum six questions. Ends with explicit user confirmation. Use when the user starts an architecture investigation, audit, migration scoping, or feature deep-dive.

Final senior-architect review of a completed investigation. Reads the brief, the plan, the synthesis, a sample of per-item outputs, and the trace log; returns a written review that an engineering leader would sign — or send back. Use as the closing skill of an investigation, after `synthesize-investigation`.

Audit a freshly-written Investigation Brief for gaps, ambiguity, and weak definitions, then close every gap — by re-reading the grilling, re-reading the codebase, or grilling the user again via AskUserQuestion. Iterates until the brief is solid. Invoked by the `/architecture-investigation:investigate` orchestrator after `write-investigation-brief` and before the user reviews. Sets `status: reviewed` when done.

Audit a freshly-written investigation plan for gaps — vague verifications, missing schema rows, underweight phases, single-option strategies — then close every gap by re-reading the brief, re-reading the codebase, or grilling the user again via AskUserQuestion. Iterates until the plan is solid. Invoked by the `/architecture-investigation:investigate` orchestrator after `write-investigation-plan` and before the user reviews. Sets `status: reviewed` when done.

Peer-review a verified plan-step output from an engineering-judgment perspective. Reads the step's output, considers what an experienced architect would push back on, and returns improvement suggestions. Use after `verify-step` passes, before moving to the next step.
