Accept

Final validation that a feature meets all specification requirements and success criteria.

What It Does

The accept phase:

1. Verifies all work packages completed — every WP is in done state
2. Validates against spec — every requirement from spec has implementation
3. Checks success criteria — success metrics are measurably met
4. Confirms no ambiguities — no [NEEDS CLARIFICATION] markers remain
5. Produces acceptance report — detailed validation results
6. Marks feature accepted — ready for merge to main

Quick Usage

Manual Acceptance Process

Step 1: Verify All WPs Done

agileplus show 001 --all-wps

Output:

WP01: Database      [████████] done
WP02: Models        [████████] done
WP03: SendGrid      [████████] done
WP04: Queue         [████████] done
WP05: Handlers      [████████] done
WP06: API           [████████] done
WP07: Tests         [████████] done

All should show done. If any are planned, doing, or for_review, they're not ready yet.

Step 2: Compare Requirements to Implementation

# View spec requirements
grep -A 50 "## Functional Requirements" \
  kitty-specs/001-feature/spec.md

# View test coverage
grep "fn test_" tests/email_integration_tests.rs

# Verify mapping:
# - REQ-1 → test_welcome_email
# - REQ-2 → test_mention_notification
# etc.

Step 3: Test Success Criteria

For each success criterion:

# Example: "95% of emails sent within 5 minutes"

# Run integration test
cargo test email_delivery_time

# Check results
# Expected: Emails arrive within 300 seconds, >95% success rate

Step 4: Run Quality Gates

# All tests
cargo test --all

# No warnings
cargo clippy

# Format OK
cargo fmt --check

# Security
cargo audit

# Doc coverage
cargo doc --no-deps

All should pass.

Step 5: Prepare Acceptance Report

Document your findings:

# Acceptance Report: 001-Email Notifications

System marks feature as accepted and creates timestamped acceptance record.

Scenarios

Scenario 1: All Criteria Met

agileplus accept 001

# Output:
# ✅ Feature 001 ACCEPTED
# Status: Accepted
# Date: 2026-03-05 14:30:00 UTC
# Ready to merge: agileplus merge 001

Scenario 2: WP Still in Progress

agileplus accept 001

# Output:
# ❌ Cannot accept: WP07 still in for_review state
#
# Pending work:
# - WP07: Tests (move to done when review complete)
#
# After WP07 is done:
#   agileplus accept 001

Scenario 3: Success Criteria Not Met

# If manual testing shows success criterion not met:

# Option 1: Fix and retest
# Go back to WP that affects the criterion, fix it, retest

# Option 2: Update criterion if requirement changed
agileplus spec edit 001
# Update the success criterion if business requirements changed
# Then retest

# When all pass:
agileplus accept 001

Post-Acceptance

After acceptance:

# Ready for merge
agileplus merge 001

# This:
# - Merges all WP branches to main
# - Removes worktrees
# - Closes tracker issues
# - Creates release tag (if configured)

Best Practices

1. Don't Skip Acceptance

Always run accept before merge, even if you're confident:

# Good: Verify before merging
agileplus accept 001
agileplus merge 001

# Risky: Skipping acceptance
agileplus merge 001  # What if a WP is still for_review?

2. Test Success Criteria Thoroughly

Don't just trust unit tests. Validate in realistic scenarios:

# Unit test passes, but...
cargo test test_email_delivery

# Manual verification with real SendGrid account
# Test with various email clients
# Check spam folder, delivery logs, etc.

3. Document Edge Cases

If you discover edge cases, document them:

## Known Limitations
- SendGrid sandbox mode has 1/second rate limit (production: 100/sec)
- Very large emails (>5MB) may timeout
- Unsubscribe links expire after 30 days of inactivity

4. Get Stakeholder Sign-Off

For important features, have PM or stakeholder accept:

# Share acceptance report with team
# Get written approval

# Mark with approver
agileplus accept 001 --approved-by "alice@example.com"

Next Steps

After acceptance:

# Merge to main
agileplus merge 001

# This completes the feature
