What problem does it solve? A plan built perfectly is still wrong if the plan itself was wrong. This Skill catches expensive plan defects—missing failure modes, unverified symbol names, scope drift, and silent edge cases—on the page before any code is written, where fixing them is cheapest. ## Core Features & Use Cases - Five-pass audit: Runs risk coverage, scope match, existence verification, edge/safety analysis, and soundness checks against the target stack's own trap list rather than a generic checklist. - Existence verification: Confirms every symbol, file, config key, package version, and API the plan names actually exists, flagging anything unconfirmable as unverified. - Structured verdict output: Emits seven named fields (Oriented, Asked, Decisions, Scope, Existence, Findings, Gated) plus a severity-tagged punch-list, and stamps the verdict into the plan file. - Use Case: Before building a streamed data export feature, run the audit on the plan to discover it never names cancellation handling on the stream and adds an unrequested format option—fix the plan, then build. ## Quick Start Ask the AI to review this implementation plan with project-verify-plan before I start building it.
