- Supports custom Docker images (`-p`)
- User-friendly help and error messages
- Exit codes indicate success/failure

**Example Usage:**
```bash
# Run specific workflow
./scripts/run-act.sh -w ci.yml

# Run specific job
./scripts/run-act.sh -w ci.yml -j lint

# List available workflows
./scripts/run-act.sh -l
```

#### [`scripts/diagnose-workflows.sh`](scripts/diagnose-workflows.sh) (9.4 KB)
- Pre-flight diagnostic tool (runs without Docker)
- Validates package.json structure and scripts
- Checks for required dependencies
- Verifies Prisma setup and schema
- Validates Playwright configuration
- Inspects node_modules installation
- Checks workflow file syntax
- Provides detailed report with actionable fixes
- Color-coded output (Green ✓, Yellow ⚠, Red ✗)

**Usage:**
```bash
chmod +x scripts/diagnose-workflows.sh
./scripts/diagnose-workflows.sh
```

#### [`scripts/test-workflows.sh`](scripts/test-workflows.sh) (8.1 KB)
- Interactive menu-driven testing tool
- Lists all workflows and jobs
- Performs dry runs (preview mode)
- Tests individual components
- Runs full CI pipeline
- Verbose output mode
- Built-in diagnostics
- Saves logs to `/tmp/` for analysis
- Color-coded output with summary report

**Menu Options:**
1. List all workflows
2. Dry run preview
3. Test Prisma setup
4. Test linting
5. Test build
6. Test E2E tests
7. Run full CI pipeline
8. Run with verbose output
9. Diagnose issues

**Usage:**
```bash
chmod +x scripts/test-workflows.sh
./scripts/test-workflows.sh
```

### 4. **GitHub Workflows** (16 Workflow Files)

All workflows are properly configured for act testing:

- `ci.yml` - Main CI/CD pipeline (lint, build, e2e tests)
- `code-review.yml` - Automated code review
- `auto-merge.yml` - Automatic PR merging
- `issue-triage.yml` - Issue categorization
- `pr-management.yml` - PR labeling and management
- `merge-conflict-check.yml` - Conflict detection
- `planning.yml` - Architecture and PRD review
- `quality-metrics.yml` - Code quality metrics
- `size-limits.yml` - Bundle size checks
- `deployment.yml` - Production deployment
- `development.yml` - Development environment setup
- `cpp-build.yml` - C++ DBAL daemon build
- Plus 4 others

All workflows use `runs-on: ubuntu-latest` and are compatible with act.

## Getting Started with Act

### 1. **Install Act**

**macOS:**
```bash
brew install act
```

**Linux:**
```bash
curl -s https://raw.githubusercontent.com/nektos/act/master/install.sh | sudo bash
```

**Windows:**
```powershell
choco install act-cli
```

### 2. **Verify Installation**

```bash
act --version
docker info
```

### 3. **Run Diagnostics** (No Docker Required)

```bash
chmod +x scripts/diagnose-workflows.sh
./scripts/diagnose-workflows.sh
```

### 4. **Test a Single Workflow**

```bash
npm run act:lint        # Test linting only
```

### 5. **Run Full CI Pipeline**

```bash
npm run act             # Run all CI jobs
```

---

## Recommendations for Improvement

### 1. ✅ **`.actrc` Configuration File**

`.actrc` is included in the repository root for consistent configuration:

```env
-P ubuntu-latest=catthehacker/ubuntu:act-latest
--env ACT=true
-v
```

**Benefit:** Users get consistent behavior without manual `-P` flags.

### 2. ⭐ **Add Act to GitHub Wiki/Docs**

Create a quickstart guide in `.github/` or link from main README:

```markdown
## Local Testing with Act

To run GitHub Actions workflows locally before pushing:

1. Install: `brew install act` (macOS) or see [installation guide](docs/guides/ACT_TESTING.md)
2. Run: `npm run act:lint` or `npm run act`
3. Troubleshoot: `./scripts/diagnose-workflows.sh`

See [comprehensive guide](docs/guides/ACT_TESTING.md) for details.
```

### 3. ✅ **`.secrets` Template**

`.secrets.example` is included for local secrets management:

```env
GITHUB_TOKEN=ghp_your_token_here
```

Copy to `.secrets` and keep it gitignored.

### 4. **GHA → NPM Script Mapping**

Document all GitHub Actions as npm scripts for quick access:

Currently available:
- ✅ `npm run act` → Full CI pipeline
- ✅ `npm run act:lint` → ESLint
- ✅ `npm run act:e2e` → Playwright tests

Consider adding:
- `npm run act:build` → Production build
- `npm run act:typecheck` → TypeScript checks
- `npm run act:prisma` → Database setup
- `npm run act:all` → All checks (lint + build + tests)

### 5. ✅ **Pre-commit Hook** (Optional)

Install the provided hook:

```bash
cp scripts/pre-commit.hook .git/hooks/pre-commit
chmod +x .git/hooks/pre-commit
```

### 6. ✅ **Pre-push Hook** (Optional)

Install the provided hook:

```bash
cp scripts/pre-push.hook .git/hooks/pre-push
chmod +x .git/hooks/pre-push
```

Skip with `git push --no-verify` or `SKIP_ACT_PRE_PUSH=1` when needed.

### 7. **CI Documentation Update**

In `.github/workflows/README.md`, add section:

```markdown
## Testing Locally with Act

Before pushing, test workflows locally:

```bash
npm run act              # Full CI pipeline
npm run act:lint        # Lint only
npm run act:e2e         # E2E tests only
```

See [Act Testing Guide](../../docs/guides/ACT_TESTING.md) for details.
```

## Known Limitations & Workarounds

### 1. **Docker Image Size**
- **Issue:** First run downloads ~5GB Docker image
- **Workaround:** Use smaller image: `act -P ubuntu-latest=catthehacker/ubuntu:act-latest`
- **Status:** Documented in guides

### 2. **GitHub Secrets**
- **Issue:** GitHub Secrets not available locally
- **Workaround:** Use `.secrets` file with `--secret-file`
- **Status:** Documented with examples

### 3. **Workflow_run Events**
- **Issue:** Some workflows triggered by other workflows need simulation
- **Workaround:** Use custom event payloads or manual triggering
- **Status:** Documented in technical guide

### 4. **Large Workflows**
- **Issue:** Some workflows may timeout on slower systems
- **Workaround:** Test individual jobs with `-j` flag
- **Status:** Workaround provided in scripts
