What problem does it solve? Flawed implementation plans cause wasted engineering hours 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: Evaluates plans across End-State Alignment, Lean Execution, Architectural Fitness, Blind Spots, and Plan Completeness, producing severity-ranked findings (CRITICAL / WARNING / OBSERVATION). - Grounding and codebase verification: Checks that referenced file paths and symbols actually exist, and optionally launches a deep verification pass on the riskiest claims with file:line evidence. - Interactive triage workflow: Presents findings one at a time with fix options, applies approved edits directly to the plan file, and supports resuming from a saved report. - Use Case: After drafting an implementation plan with /10x-plan, run this Skill to validate the plan against the actual codebase, receive a verdict (SOUND / REVISE / RETHINK), and triage each finding before starting implementation. ## Quick Start Ask the assistant to review the implementation plan at context/changes/my-change/plan.md and triage the findings.
