Validate Acceptance Criteria

Check whether all acceptance criteria from the issue have been addressed before creating a commit or PR.

Task

IMPORTANT: This skill implements the ACCEPTANCE CRITERIA rule from work-items.md

Before committing or creating a PR, verify that all acceptance criteria have been met.

Workflow

1. Locate Criteria Find acceptance criteria from one of these sources (in priority order):

   • Session file: .claude/sessions/<branch>.md
   • Cached work item: use /onus:fetch if needed
   • GitHub issue directly: gh issue view <number>

2. Review Each Criterion For each acceptance criterion:

   • Check if implementation addresses it
   • Look at relevant code changes
   • Verify tests exist if applicable

3. Report Status Present findings with clear status for each criterion

Output Format

## Acceptance Criteria Validation

**Issue**: #[number] - [title]
**Branch**: [current branch]

### Criteria Status

| Status | Criterion | Evidence |
|--------|-----------|----------|
| ✅ | [criterion text] | [file:line or description] |
| ⚠️ | [criterion text] | [partial implementation note] |
| ❌ | [criterion text] | [not found or missing] |

### Summary
- Completed: X of Y
- [proceed/address issues before commit]

### Next Steps
[what needs to be done for incomplete items]

Example

User: /onus:validate-criteria

Claude: ## Acceptance Criteria Validation

**Issue**: #42 - Add user authentication
**Branch**: issue/feature-42/auth

### Criteria Status

| Status | Criterion | Evidence |
|--------|-----------|----------|
| ✅ | Login form with email/password | src/components/LoginForm.tsx:15-80 |
| ✅ | JWT token handling | src/lib/auth.ts:20-45 |
| ✅ | Error messages for invalid credentials | src/components/LoginForm.tsx:35-50 |
| ⚠️ | Remember me checkbox | Implemented but not tested |
| ❌ | Password reset flow | Not started |

### Summary
- Completed: 3 of 5 (1 partial, 1 missing)
- Address issues before commit

### Next Steps
1. Add tests for "Remember me" functionality
2. Implement password reset flow or remove from scope
3. Update issue if scope changed

When to Use

Invoke this skill:

• Before running /onus:commit
• Before running /onus:pr
• When unsure if work is complete
• During code review

Notes

• Incomplete criteria doesn't always mean "don't commit"
• Partial implementations might be intentional (phased delivery)
• If scope changed, update the issue first
• Session file criteria and issue criteria should match
