# GitHub Workflows Documentation

This directory contains automated workflows for CI/CD, code quality, and comprehensive AI-assisted development throughout the entire SDLC.

## 🚦 Enterprise Gated Tree Workflow

MetaBuilder uses a **Unified Enterprise Gated Pipeline** that consolidates all CI/CD, deployment, and development assistance into a single workflow with clear gate visualization.

**📖 Complete Guide:** [Enterprise Gated Workflow Documentation](../../docs/ENTERPRISE_GATED_WORKFLOW.md)

### Quick Overview

All PRs and deployments flow through 6 sequential gates in a single workflow:

1. **Gate 1: Code Quality** - Prisma, TypeScript, Lint, Security (7 atomic steps)
2. **Gate 2: Testing** - Unit, E2E, DBAL Daemon tests (3 atomic steps)
3. **Gate 3: Build & Package** - Application build, quality metrics (2 atomic steps)
4. **Gate 4: Development Assistance** - Architectural feedback, Copilot interaction (PR only)
5. **Gate 5: Staging Deployment** - Automatic deployment to staging (main branch push)
6. **Gate 6: Production Deployment** - Manual approval required (release/workflow_dispatch)

**Key Benefits:**
- ✅ **Single unified workflow** - No confusion about which pipeline runs what
- ✅ Sequential gates prevent wasted resources
- ✅ Tree structure for clear visualization of all validation steps
- ✅ Automatic merge after approval
- ✅ Conditional execution based on trigger (PR vs push vs release)
- ✅ Complete audit trail for all deployments

### Pipeline Consolidation (Jan 2026)

**Consolidated into `gated-pipeline.yml`:**
- ✅ `gated-ci.yml` (1048 lines) - CI with gates 1-5
- ✅ `gated-deployment.yml` (617 lines) - Deployment workflows
- ✅ `development.yml` (360 lines) - Development assistance

**Result:** Single 1287-line workflow with all functionality preserved and no duplication.

**Previous Deprecated and Removed (Dec 2025):**
- ❌ `ci/ci.yml` - Replaced by gated workflows
- ❌ `quality/deployment.yml` - Replaced by gated workflows

See [Legacy Pipeline Cruft Report](../../docs/LEGACY_PIPELINE_CRUFT_REPORT.md) for analysis.

## 🤖 GitHub Copilot Integration

All workflows are designed to work seamlessly with **GitHub Copilot** to assist throughout the Software Development Lifecycle:

- **Planning Phase**: Architecture review, PRD alignment, implementation guidance
- **Development Phase**: Continuous quality feedback, code suggestions, refactoring opportunities
- **Testing Phase**: Automated code review, security checks, quality validation
- **Deployment Phase**: Pre-deployment validation, health checks, monitoring
- **Maintenance Phase**: Issue triage, automated fixes, dependency management

**📖 Copilot Instructions:** [.github/copilot-instructions.md](../copilot-instructions.md)

### 🔄 Supporting Workflows

#### Issue and PR Triage (`triage.yml`)
**Triggered on:** Issues (opened/edited/reopened) and Pull Requests (opened/reopened/synchronize/edited)

**Purpose:** Quickly categorize inbound work so reviewers know what to look at first.

- Auto-applies labels for type (bug/enhancement/docs/security/testing/performance) and area (frontend/backend/database/workflows/documentation)
- Sets a default priority and highlights beginner-friendly issues
- Flags missing information (repro steps, expected/actual results, versions) with a checklist comment
- For PRs, labels areas touched, estimates risk based on change size and critical paths, and prompts for test plans/screenshots/linked issues
- Mentions **@copilot** to sanity-check the triage with GitHub-native AI

This workflow runs alongside the gated pipeline to provide quick triage feedback.

### 🗑️ Legacy Workflows (Removed)

### Testing Workflows Locally with Act

Before pushing to GitHub, test workflows locally using [act](https://github.com/nektos/act):

```bash
# Quick diagnostics (no act required)
./scripts/diagnose-workflows.sh

# Interactive workflow testing
./scripts/test-workflows.sh

# Or use act directly
act -l                    # List all workflows
act push                  # Run CI pipeline
act -j lint              # Test linting job
act -j build             # Test build job
```

**📖 See [ACT_TESTING.md](../../docs/ACT_TESTING.md) for comprehensive act testing guide**

### Running Locally

```bash
# Run linter
bun run lint

# Fix linting issues automatically
bun run lint:fix

# Run e2e tests
bun run test:e2e

# Run e2e tests with UI
bun run test:e2e:ui

## Best Practices

### For Development
1. **Follow declarative-first principles** - Prefer JSON + Lua over TypeScript
2. **Keep components under 150 LOC** - Break large files into smaller ones
3. **Use generic renderers** - Avoid hardcoded component TSX files
4. **Store config in database** - Use Prisma, not hardcoded values
5. **Organize as packages** - Self-contained features with seed data

### For Pull Requests

### For Pull Requests
1. **Write descriptive PR titles** - Used for automatic labeling
2. **Link issues in PR descriptions** - Enables automatic issue closing
3. **Keep PRs focused and small** - Easier to review and merge
4. **Address all review comments** - Even warnings should be considered
5. **Test locally before pushing** - Run lint and tests
6. **Don't commit console.log statements** - Will be flagged in review
7. **Remove debugger statements** - Treated as blocking issues
8. **Review refactoring suggestions** - Continuous improvement opportunities

### For Issues
1. **Use clear, descriptive titles** - Helps with automatic categorization
2. **Provide context** - Link to docs/getting-started/PRD.md sections, mention permission levels
3. **Consider architecture** - Is this declarative? Package-worthy? Multi-tenant?
4. **Use labels appropriately** - Triggers relevant workflow automation
5. **Engage with @copilot** - Get AI assistance throughout implementation

## Troubleshooting

### Running Act to Find Workflow Issues

Use act to test workflows locally and identify issues before pushing:

```bash
# Run full diagnostics
./scripts/diagnose-workflows.sh

# Test specific failing job
act -j <job-name> -v

# Test entire CI pipeline
./scripts/test-workflows.sh
```

**📖 Complete guide:** [ACT_TESTING.md](../../docs/ACT_TESTING.md)

### PR Not Auto-Merging
- Check that all CI checks passed
- Verify PR has approval
- Ensure no merge conflicts
- Confirm PR is not in draft mode

### Tests Failing
- Run tests locally: `bun run test:e2e`
- Check test report artifacts in GitHub Actions
- Ensure dev server starts correctly
- Test with act: `act -j test-e2e`

### Linting Errors
- Run `bun run lint:fix` to auto-fix
- Review errors: `bun run lint`
- Check `eslint.config.js` for rule configuration
- Test with act: `act -j lint`

### Build Failures
- Test locally: `bun run build`
- Check for TypeScript errors
- Verify all dependencies are installed
- Test with act: `act -j build`

### Prisma Issues
- Ensure schema exists: `prisma/schema.prisma`
- Generate client: `bunx prisma generate`
- Run migrations: `bunx prisma migrate dev`
- Test with act: `act -j prisma-check`

## Contributing

When adding new workflows:
1. Document the workflow in this README
2. Add appropriate error handling
3. Test the workflow on a test branch
4. Ensure proper permissions are set
5. Add labels if needed (they'll be created automatically)

## Security

Workflows use `GITHUB_TOKEN` with minimal required permissions:
- `contents: read/write` - For reading code and merging PRs
- `pull-requests: write` - For commenting and managing PRs
- `issues: write` - For managing issues
- `checks: read` - For reading CI status

No secrets are required for basic functionality.
