What problem does it solve? Flawed implementation plans cause wasted hours of rework when gaps, contradictions, or unverifiable assumptions surface mid-build. This Skill catches substance problems in a plan before any code is written, through structured analysis and interactive triage. ## Core Features & Use Cases - Multi-dimensional plan analysis: Scores plans across End-State Alignment, Lean Execution, Architectural Fitness, Blind Spots, and Plan Completeness with severity- and impact-rated findings. - Grounding and codebase verification: Checks that referenced file paths and symbols actually exist, and uses a sub-agent to verify the riskiest claims against real code with file:line evidence. - Interactive triage with resume: Presents findings with fix options, applies chosen edits directly to the plan, and supports resuming from a saved report via the PLAN-REVIEW-REPORT marker. - Use Case: After drafting an implementation plan with /10x-plan, run this Skill to validate the plan's phases, success criteria, and contract surfaces, then triage each finding before starting /10x-implement. ## Quick Start Ask the assistant to review the implementation plan at context/changes/my-change/plan.md and triage the findings.
