Add spec-review skill for automated verification

[chapel]

Summary

• Implements automated post-implementation verification workflow
• Uses two-subagent pattern for comprehensive review:
  • Verification subagent: Checks AC coverage (implementation + tests)
  • Gap analysis subagent: Identifies missing functionality and incomplete tests
• Consolidates results into actionable summary with specific fixes needed

Usage

/spec-review @spec-slug

Integration

• Works with /task-work - run before creating PR
• Complements /local-review - focuses on spec alignment rather than test quality
• Can be used during PR review for holistic verification

Test Plan

• Skill file created with proper frontmatter structure
• Follows established pattern from other skills (local-review, spec-plan)
• Documentation includes workflow steps, subagent prompts, and example output
• All tests passing (1567 tests)
• Manual validation: Use skill in real workflow to verify spec implementation

PR Review Summary

Task Context

Task: 01KGGPN0 - Create spec-review skill for automated verification + gap analysis

Review Results

Skill Structure:

• ✅ Proper frontmatter (name, description)
• ✅ Follows established pattern from other skills (local-review, spec-plan)
• ✅ Clear documentation with workflow steps, subagent prompts, and examples
• ✅ Integration points with existing skills documented

CI Status:

• ✅ All tests passing (1567 tests)
• ✅ No unresolved comments
• ✅ Claude review passed

Quality Assessment:

Since this is infrastructure work (creating a skill/documentation file) without a spec, the review focuses on:

1. Pattern Consistency: Matches structure of existing skills ✅
2. Documentation Quality: Clear, comprehensive, with examples ✅
3. Integration: Properly integrated with skill system ✅
4. Completeness: Covers all necessary aspects (usage, workflow, subagent config) ✅

Note: This task has no spec (infrastructure work), so traditional AC coverage verification doesn't apply. The skill itself documents how to perform AC verification for other implementations.

Verdict

✅ Ready to merge - All quality gates pass.

The skill is well-structured, follows established patterns, and provides clear guidance for automated spec verification workflows.
