What problem does it solve? Flawed implementation plans waste hours of development time when contradictions, missing phases, or unverified assumptions surface mid-build. This Skill catches substance problems in a plan before any code is written, through structured analysis and codebase verification. ## Core Features & Use Cases - Internal consistency scanning: Detects contradictions between current-state analysis and phases, promise gaps between success criteria and planned work, and contract breaks across API endpoints. - Grounding and codebase verification: Checks that referenced file paths and symbols actually exist, and launches a sub-agent to verify the riskiest claims against real code with file:line evidence. - Five-dimension analysis with triage: Scores plans on End-State Alignment, Lean Execution, Architectural Fitness, Blind Spots, and Plan Completeness, then walks each finding through an interactive fix/skip/accept decision loop. - Use Case: After drafting a plan with /10x-plan, run this Skill to get a SOUND/REVISE/RETHINK verdict with severity-ranked findings and concrete fix options before starting implementation. ## Quick Start Ask the assistant to review the plan at context/changes/my-change/plan.md and triage the findings.
