What problem does it solve? Plans and research documents often contain unverified claims, stale file references, and gaps that only surface during implementation. This Skill validates those artifacts against the actual repository before any code is written, catching critical errors early. ## Core Features & Use Cases - Evidence-Based Validation: Verifies every claim in plan and research documents against real code, optionally delegating to codebase locator, analyzer, and pattern-finder agents. - Severity-Classified Findings: Classifies issues as critical, major, or minor, each with evidence (file:line references) and an exact fix recommendation. - Structured Review Output: Produces a consistent review report with status, findings, required changes, and split automated/manual verification checklists, plus an optional compounding handoff for plan-implement-review loops. - Use Case: Before implementing a multi-phase refactor described in _scratchpad/plans/, run this Skill to confirm the referenced files exist, phases are executable, and success criteria are verifiable. ## Quick Start Review the implementation plan at _scratchpad/plans/my-plan.md and validate its claims against the codebase.
