What problem does it solve? Flawed implementation plans cause wasted engineering hours when problems surface mid-build. This Skill catches substance problems in a plan — contradictions, missing phases, ungrounded file paths, architectural mismatches — before any code is written. ## Core Features & Use Cases - Multi-dimensional analysis: Scores plans across End-State Alignment, Lean Execution, Architectural Fitness, Blind Spots, and Plan Completeness with PASS/WARNING/FAIL verdicts. - 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. - Interactive triage workflow: Presents findings with severity and impact ratings, offers fix options with tradeoffs, applies accepted fixes directly to the plan, and supports saving/resuming review reports. - Use Case: After drafting an implementation plan with /10x-plan, run this Skill to validate the plan against the actual codebase, get a SOUND/REVISE/RETHINK verdict, and triage each finding before starting implementation. ## Quick Start Ask the assistant to review the plan at context/changes/my-change/plan.md and triage the findings.
