Phase 3 (Implementation) Validation Skill

Purpose: Automate validation of Implementation Phase before advancing to Testing Phase.

When to Use: When orchestrator needs to verify implementation is ready for comprehensive testing.

How to Use This Skill

Executable Script: execute.sh

# Basic usage
bash .claude/skills/phase-3-validator/execute.sh <feature-name> [work-type] [required-percentage]

# Examples:
bash .claude/skills/phase-3-validator/execute.sh events
bash .claude/skills/phase-3-validator/execute.sh vetting Bug 75
bash .claude/skills/phase-3-validator/execute.sh payment-processing Hotfix 70

Parameters:

• feature-name: Name of feature being validated (required)
• work-type: Feature|Bug|Hotfix|Docs|Refactor (optional, default: Feature)
• required-percentage: Override quality gate threshold (optional)

Script validates:

• API and Web build successfully
• Implementation completeness (endpoints, components, migrations, services)
• Code quality (TypeScript, C#, ESLint, error handling)
• Testing infrastructure (unit, integration, E2E tests, fixtures)
• Documentation (implementation notes, API docs, examples, limitations)

Exit codes:

• 0: Implementation Phase complete, ready for Testing Phase
• 1: Implementation incomplete or quality gates not met

Quality Gate Checklist (85% Required for Features)

Code Compilation (10 points)

• API builds without errors (5 points)
• Web builds without errors (5 points)

Implementation Completeness (15 points)

• Service layer implemented (2 points)
• Type definitions match API (2 points)

Code Quality (10 points)

• No TypeScript errors (2 points)
• No C# warnings (2 points)
• ESLint passes (2 points)
• Proper error handling (2 points)
• Code follows project patterns (2 points)

Testing Infrastructure (10 points)

• Unit tests created (3 points)
• Integration test stubs created (3 points)
• E2E test files created (2 points)
• Test data/fixtures prepared (2 points)

Documentation (5 points)

• Implementation notes documented (2 points)
• API endpoints documented (1 point)
• Component usage examples (1 point)
• Known limitations noted (1 point)

Usage Examples

From Orchestrator

Use the phase-3-validator skill to check if implementation is ready for testing

Manual Validation

# Run validation for specific feature
bash .claude/skills/phase-3-validator.md "event-management"

Common Issues

Issue: Build Failures

Critical - Must fix before testing:

• Compilation errors in API
• TypeScript errors in Web
• Missing dependencies

Solution: Loop back to react-developer or backend-developer agents.

Issue: Missing Test Files

Solution: Test files should exist even if not fully implemented:

• Unit tests for services and components
• Integration test stubs for API endpoints
• E2E test files for user workflows

Issue: Architectural Violations

Critical violations:

• Direct database access from Web service
• Using Blazor patterns in React code
• Missing error handling in API endpoints

Issue: No Type Definitions

Solution: After creating API endpoints:

cd packages/shared-types
npm run generate

First Vertical Slice Checkpoint

MANDATORY: After implementing the first vertical slice (one complete feature from UI → API → Database):

1. Run phase-3-validator
2. If score ≥ 85%, PAUSE for human review
3. Wait for explicit approval before continuing with remaining features

Why: This catches architectural issues early before they propagate to all features.

Integration with Quality Gates

This skill enforces the quality gate thresholds by work type:

• Feature: 85% required (43/50 points)
• Bug Fix: 75% required (38/50 points)
• Hotfix: 70% required (35/50 points)
• Refactoring: 90% required (45/50 points)

Progressive Disclosure

Initial Context: Show compilation and critical checks only On Request: Show full validation with all scoring On Failure: Show specific failing items with fix suggestions On First Vertical Slice: Show full report + human review prompt

Remember: This skill validates implementation quality but doesn't test functionality. That's Phase 4's job. This ensures code is test-ready.
