- 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

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
