Agent Skills: Gate Check

Gate Check

Validate all gate criteria are met before advancing the PRD lifecycle version.

Workflow Overview

1. Load Gate Criteria → Read target gate requirements from PRD.md
2. Verify Evidence → Check required artifacts exist with valid IDs
3. Assess Readiness → Evaluate handoff requirements
4. Report → Pass/Block with specific gaps

Core Output Template

| Element | Definition | Evidence | |---------|------------|----------| | Target Gate | Version being validated | v0.3 → v0.4 | | Status | Pass or Block | Clear determination | | Missing Artifacts | What's not complete | Specific list with IDs | | Recommendation | Action to take | Proceed / Address gaps |

Gate Reference

| Gate | Focus | Key Artifacts | |------|-------|---------------| | v0.1 → v0.2 | Problem validated | CFD-XXX evidence | | v0.2 → v0.3 | Market defined | Segment definitions | | v0.3 → v0.4 | Commercial viable | BR-XXX, pricing | | v0.4 → v0.5 | Journeys mapped | UJ-XXX complete | | v0.5 → v0.6 | Risks addressed | Risk register | | v0.6 → v0.7 | Architecture set | API-XXX, schemas | | v0.7 → v0.8 | Build complete | Tests passing | | v0.8 → v0.9 | Deployed | Live environment | | v0.9 → v1.0 | Launched | Metrics tracking |

Step 1: Load Gate Criteria

1. Read PRD.md gate section for target version
2. Extract all required criteria
3. Identify artifact types needed (BR, UJ, API, CFD)

Checklist

• [ ] Target gate identified
• [ ] All criteria extracted
• [ ] Required artifact types listed

Step 2: Verify Evidence

For each required criterion:

1. Check artifact exists in SoT/
2. Verify artifact status is not "Draft"
3. Confirm cross-references are valid
4. Check for required CFD-XXX evidence

Evidence Matrix

| Criterion Type | Verification | |----------------|--------------| | Business Rule | BR-XXX exists, status Active | | User Journey | UJ-XXX exists, all steps defined | | API Contract | API-XXX exists, endpoints specified | | Customer Evidence | CFD-XXX linked to BR-XXX |

Checklist

• [ ] All required BR-XXX verified
• [ ] All required UJ-XXX verified
• [ ] All required API-XXX verified
• [ ] Evidence chain (CFD → BR) validated

Step 3: Assess Handoff Readiness

Check downstream requirements:

1. Next agent has context needed
2. No open blockers in current EPIC
3. Documentation is current

Checklist

• [ ] EPIC Session State section has no blockers
• [ ] README.md is synchronized
• [ ] Handoff documentation exists

Step 4: Generate Report

## Gate Check Report: v0.X → v0.Y

**Status**: [PASS / BLOCK]
**Date**: YYYY-MM-DD

### Criteria Assessment

| Criterion | Status | Evidence |
|-----------|--------|----------|
| [Criterion 1] | ✅/❌ | [ID or gap] |
| [Criterion 2] | ✅/❌ | [ID or gap] |

### Missing Artifacts
- [ ] [Specific gap with required action]

### Recommendation
[Proceed to v0.Y / Address [N] gaps before advancing]

Quality Gates

Pass Checklist

• [ ] All criteria evaluated (none skipped)
• [ ] Evidence is traceable to IDs
• [ ] Recommendation is actionable

Testability Check

• [ ] Report can be validated against PRD.md criteria
• [ ] Missing artifacts are specific and findable

Anti-Patterns

| Pattern | Example | Fix | |---------|---------|-----| | Skipping criteria | "Probably fine" | → Verify each explicitly | | Vague gaps | "Needs more work" | → Cite specific missing ID | | Override blocks | Advancing despite fails | → Address gaps first |

Boundaries

DO:

• Validate against documented criteria
• Identify specific gaps
• Provide actionable recommendations

DON'T:

• Create missing artifacts (just report)
• Override gate blocks
• Make subjective quality judgments

Handoff

After gate check:

• If PASS: Advance PRD version, trigger ghm-status-sync
• If BLOCK: Return to current stage, address gaps
