Validate Plan

You are tasked with validating that an implementation plan was correctly executed, verifying all success criteria and identifying any deviations or issues.

Initial Setup

When invoked:

1. Determine context - Review what was implemented
2. Locate the plan - Find the implementation plan document
3. Gather implementation evidence through git and testing

Validation Process

Step 1: Context Discovery

1. Read the implementation plan completely

2. Identify what should have changed:

   • List all files that should be modified
   • Note all success criteria (automated and manual)
   • Identify key functionality to verify

3. Spawn parallel research tasks to discover implementation:

   • Verify code changes match plan specifications
   • Check if tests were added/modified as specified
   • Validate that success criteria are met

Step 2: Systematic Validation

For each phase in the plan:

1. Check completion status:

   • Look for checkmarks in the plan (- [x])
   • Verify actual code matches claimed completion

2. Run automated verification:

   • Execute each command from "Automated Verification"
   • Document pass/fail status
   • If failures, investigate root cause

3. Assess manual criteria:

   • List what needs manual testing
   • Provide clear steps for user verification

Step 3: Generate Validation Report

Create comprehensive validation summary:

## Validation Report: [Plan Name]

### Implementation Status
✓ Phase 1: [Name] - Fully implemented
✓ Phase 2: [Name] - Fully implemented
⚠️ Phase 3: [Name] - Partially implemented (see issues)

### Automated Verification Results
✓ Build passes
✓ Tests pass
✗ Linting issues (3 warnings)

### Code Review Findings

#### Matches Plan:
- [What was correctly implemented]
- [Another correct implementation]

#### Deviations from Plan:
- [Any differences from plan]
- [Explanation of deviation]

#### Potential Issues:
- [Any problems discovered]
- [Risk or concern]

### Manual Testing Required:
1. UI functionality:
   - [ ] Verify feature appears correctly
   - [ ] Test error states

2. Integration:
   - [ ] Confirm works with existing components
   - [ ] Check performance

### Recommendations:
- [Action items before merge]
- [Improvements to consider]

Important Guidelines

1. Be thorough but practical - Focus on what matters
2. Run all automated checks - Don't skip verification
3. Document everything - Both successes and issues
4. Think critically - Question if implementation solves the problem
5. Consider maintenance - Will this be maintainable?

Validation Checklist

Always verify:

• All phases marked complete are actually done
• Automated tests pass
• Code follows existing patterns
• No regressions introduced
• Error handling is robust
• Documentation updated if needed
