What problem does it solve? A flawed build plan approved without review is the most expensive defect in a spec-driven development loop, because the builder faithfully implements whatever the plan says. This Skill catches plan defects — invented requirements, uncheckable criteria, wrong repo facts — before any code is written. ## Core Features & Use Cases - Adversarial plan review: Sends the build doc and scope doc verbatim to fresh inspector models (Claude, GPT, Gemini, DeepSeek, or Qwen) that hunt for reasons to reject the plan across three lenses: traceability, code-book compliance, and repo reality. - Verified findings: Every BLOCKER and MAJOR finding is verified against cited line numbers before reaching the user, with refuted findings counted and dropped. - Paper trail: Appends a punch-list block and a model-named inspection stamp to the build doc, keeping a full audit history without ever editing the plan itself. - Use Case: After drafting a build plan with /blueprint, run /inspect to have an independent GPT or Claude inspector grade the plan against the blueprint rules and the actual repository before /build executes it. ## Quick Start Type /inspect with the path to a build plan document to run an adversarial pre-construction review of that plan.
