Acceptance Criteria Verification Skill

Acceptance Criteria Verification

Overview

Systematically verify each acceptance criterion and post structured reports.

Core principle: Every criterion verified. Every verification documented.

Announce at start: "I'm using acceptance-criteria-verification to verify the implementation."

The Verification Process

Step 1: Extract Criteria

Read the issue and extract all acceptance criteria:

# Get issue body
gh issue view [ISSUE_NUMBER] --json body -q '.body'

Parse out criteria (look for - [ ] or - [x] patterns in acceptance criteria section).

Step 2: Plan Verification

For each criterion, determine:

| Criterion | Test Type | How to Verify | |-----------|-----------|---------------| | [Criterion 1] | Unit test | Run specific test | | [Criterion 2] | Integration | API call + response check | | [Criterion 3] | E2E | Browser automation | | [Criterion 4] | Manual | Visual inspection |

Step 3: Execute Verification

For each criterion, run the appropriate verification:

Unit/Integration Tests

# Run specific tests
pnpm test --grep "[test pattern]"

# Or run test file
pnpm test path/to/specific.test.ts

E2E Tests

# If using Playwright
npx playwright test [test file]

# If using browser automation MCP
# Use mcp__playwright or mcp__puppeteer

Manual Verification

For criteria requiring visual or interactive verification:

Start the application
Navigate to relevant area
Perform the action
Capture screenshot if relevant
Document result

Step 4: Record Results

For each criterion, record:

Criterion: [Text from issue]
Status: PASS | FAIL | PARTIAL | SKIP
Evidence: [Test output, screenshot, observation]
Notes: [Any relevant details]

Step 5: Post Verification Report

Post a structured comment to the issue:

gh issue comment [ISSUE_NUMBER] --body "## Verification Report

**Run**: $(date -u +%Y-%m-%dT%H:%M:%SZ)
**By**: agent
**Commit**: $(git rev-parse --short HEAD)
**Branch**: $(git branch --show-current)

### Results

| # | Criterion | Status | Notes |
|---|-----------|--------|-------|
| 1 | [Criterion text] | PASS | [Notes] |
| 2 | [Criterion text] | FAIL | [What failed] |
| 3 | [Criterion text] | PARTIAL | [What works, what doesn't] |

### Summary

| Status | Count |
|--------|-------|
| PASS | X |
| FAIL | X |
| PARTIAL | X |
| SKIP | X |
| **Total** | **X** |

### Test Output

<details>
<summary>Test Results</summary>

\`\`\`
[test output here]
\`\`\`

</details>

Step 6: Update Issue Checkboxes

For each passing criterion, check it off in the issue body:

# Get current body
BODY=$(gh issue view [ISSUE_NUMBER] --json body -q '.body')

# Update checkboxes for passing criteria
# (Implementation depends on body format)

# Update issue
gh issue edit [ISSUE_NUMBER] --body "$NEW_BODY"

Step 7: Update Project Fields

# Update project fields using project-status-sync skill

# Verification status
# - All PASS → Passing
# - Any FAIL → Failing
# - Mix of PASS/PARTIAL → Partial

# Criteria Met count
# - Count of PASS criteria

# Last Verified
# - Current date

# Verified By
# - "agent"

Status Definitions

| Status | Meaning | Action | |--------|---------|--------| | PASS | Criterion fully met, verified working | Check off in issue | | FAIL | Criterion not met, requires fix | Document what failed, return to development | | PARTIAL | Works with issues, needs improvement | Document issues, may need fix | | SKIP | Could not verify (blocked, N/A, etc.) | Document reason |

E2E Verification Best Practices

When using browser automation:

Start fresh - New browser session for each verification
Capture evidence - Screenshots at key points
Check visible state - Not just DOM, but visible rendering
Test error cases - Not just happy path
Clean up - Close sessions after verification

// Example verification flow (pseudo-code)
await page.goto(appUrl);
await page.click('[data-testid="new-chat"]');
await page.waitForSelector('[data-testid="chat-input"]');
await page.screenshot({ path: 'new-chat-verification.png' });
// Verify expected state
const title = await page.title();
expect(title).toContain('New Chat');

Handling Failures

When criteria fail:

Document specifically what failed
Include reproduction steps if not obvious
Capture error messages or screenshots
Return to development to fix
Re-run verification after fix

Do NOT:

Mark as PASS when it failed
Skip verification because "it should work"
Ignore intermittent failures

Verification Checklist

Before completing verification:

[ ] All acceptance criteria evaluated
[ ] Each criterion has clear PASS/FAIL/PARTIAL/SKIP status
[ ] Evidence captured for each (test output, screenshots)
[ ] Verification report posted to issue
[ ] Issue checkboxes updated for passing criteria
[ ] Project fields updated
[ ] If any failures, next steps documented

After Verification

Based on results:

| Overall Result | Next Action | |----------------|-------------| | All PASS | Proceed to code review | | Any FAIL | Return to development, fix, re-verify | | Partial only | Discuss with user - acceptable or needs fix? |
