description	Review an implementation plan for simplicity, existing patterns, current best practices, and realistic verification before execution.

Plan Validate

Use this skill to validate an implementation plan before coding starts.

Goal

Make the plan simpler, more accurate, and easier to verify without changing product code.

Required outcome

Keep the full implementation plan intact and append a Plan validation (review) section to the same document.

Process

1. Find existing patterns
   • search the codebase for similar functionality
   • prefer reuse over invention
2. Verify framework and platform behavior
   • use Context7 for relevant frameworks and libraries when available
   • use current docs or search for browser APIs, CSS, syntax, and integration details when relevant
3. Review simplicity
   • is this the simplest solution?
   • does it solve only the requested problem?
   • can we ship a smaller working version first?
4. Review plan-to-codebase fit
   • locate the likely code paths
   • challenge unsupported assumptions
   • note where the plan is missing connected areas
5. Validate dependency order
   • foundations before higher-level logic
   • explicit blockers before dependent work
6. Validate verification
   • confirm the proposed checks actually prove completion
   • tighten vague success criteria
7. Update the plan
   • remove scope creep, duplication, and avoidable abstraction
   • keep each chunk explicit about why / what / how / verification

Output

Update the same plan file with an additive Plan validation (review) section. Do not replace the plan; refine it.
