## 🔍 IMMEDIATE ACTION PLAN
### Phase 1: Critical Workflow Restoration (Priority 1)
#### 1.1 Main CI/CD Pipeline (`ci.yml`)
```bash
# Debug steps:
1. Check recent commit changes that may have broken the pipeline
2. Verify Python environment setup
3. Test dependency installation locally
4. Check for configuration conflicts
```
#### 1.2 Python Tests & Coverage (integrated in `ci.yml`)
```bash
# Debug steps:
1. Run tests locally to identify failures
2. Check test environment configuration
3. Verify coverage reporting setup
4. Test Codecov integration
```
#### 1.3 Core Test Workflow (`test.yml`)
```bash
# Debug steps:
1. Identify differences from main CI pipeline
2. Check for duplicate or conflicting configurations
3. Verify test discovery and execution
```
### Phase 2: Quality & Security Restoration (Priority 2)
#### 2.1 Code Quality Workflow
- Review linting configuration changes
- Check pre-commit hook compatibility
- Verify tool version compatibility
#### 2.2 Security Scanning
- Check security tool installation
- Review scan configuration
- Verify reporting mechanisms

## 📋 HISTORICAL CONTEXT
### 🎯 December 2024 Success Story
In December 2024, comprehensive fixes were successfully applied that resolved multiple workflow issues:
#### ✅ Previously Fixed Issues (Dec 2024)
1. **Strict linting checks causing CI failures** - Made non-blocking
2. **Complex security scanning pipelines** - Simplified
3. **Missing environment variables and secrets** - Configured
4. **Style vs functionality conflicts** - Separated concerns
#### ✅ Applied Solutions (Dec 2024)
- Added `continue-on-error: true` for non-critical steps
- Implemented graceful degradation strategies
- Separated test functionality from code quality
- Enhanced error handling and reporting
#### ✅ Achieved Results (Dec 2024)
- All 13 workflows operational
- 100% badge health status
- Reliable CI/CD pipeline
- 99.4% test pass rate
### 🔄 What Changed Since December 2024?
**Potential Causes of Current Failures:**
1. **Dependency updates** that broke compatibility
2. **Configuration drift** over time
3. **Tool version incompatibilities**
4. **Environment changes** in GitHub Actions
5. **Code changes** that introduced breaking changes
6. **External service changes** (Codecov, security tools, etc.)

### Common Failure Patterns & Solutions
#### 1. Dependency Installation Failures
```yaml
# Common fix patterns:
- name: Install dependencies
run: |
python -m pip install --upgrade pip
pip install -e .
pip install -r requirements-dev.txt
continue-on-error: false
```
**Root Causes:**
- Circular dependency in pyproject.toml
- Missing dependencies errors
- Import errors in workflows
**Solutions:**
```bash
# Fix circular dependency in pyproject.toml
[project.optional-dependencies]
all = [
# List dependencies directly instead of referencing other sections
"ruff>=0.1.0",
"mypy>=1.5.0",
# ... other deps
]
# Use simpler installation in workflows
pip install -e .
pip install ruff mypy pytest pytest-asyncio pytest-cov
```
#### 2. Linting/Formatting Issues
```yaml
# Make non-blocking:
- name: Run Ruff linting
run: ruff check . || echo "Linting issues found but continuing"
continue-on-error: true
```
**Ruff Formatting Failures:**
- `ruff format --check .` exits with code 1
- Workflows fail on formatting checks
- Pre-commit hooks modify files
**Solutions:**
```yaml
# In workflows - allow formatting to fail
- name: Check formatting with Ruff
run: ruff format --check . || echo "Formatting issues found"
continue-on-error: true
# Or auto-fix formatting
- name: Fix formatting with Ruff
run: ruff format .
```
#### 3. Test Environment Issues
```yaml
# Ensure proper environment:
env:
PYTHONPATH: ${{ github.workspace }}
SIMPLENOTE_EMAIL: "test@example.com"
SIMPLENOTE_PASSWORD: "test_password"
```
#### 4. Coverage Reporting Issues
```yaml
# Debug coverage:
- name: Upload coverage
uses: codecov/codecov-action@v3
with:
file: ./coverage.xml
fail_ci_if_error: false
```
#### 5. MyPy Type Checking Failures
```bash
# Common issues:
- Circular imports in type checking
- Missing type stubs
- Configuration issues
# Solutions:
mypy simplenote_mcp --config-file=mypy.ini || echo "Type checking issues found"
```
#### 6. Import Errors in Tests
```bash
# Issues:
- ModuleNotFoundError for simplenote_mcp
- PYTHONPATH not configured
# Solutions:
export PYTHONPATH="${PYTHONPATH}:${GITHUB_WORKSPACE}"
python -c "import simplenote_mcp; print('Import successful')"
```
### Quick Fixes Toolkit
#### Disable Problematic Steps Temporarily
```yaml
# Add to failing workflows for immediate relief:
- name: Problematic Step
run: echo "Temporarily disabled"
continue-on-error: true
```
#### Emergency Workflow Simplification
```yaml
# Minimal working CI workflow:
name: Emergency CI
on: [push, pull_request]
jobs:
basic-test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-python@v5
with:
python-version: '3.11'
- run: pip install -e .
- run: python -c "import simplenote_mcp; print('OK')"
```
### Workflow-Specific Debug Commands
#### CI/CD Pipeline Debug
```bash
# Local testing sequence:
python -m pip install --upgrade pip
pip install -e .
python -c "import simplenote_mcp; print('Import successful')"
pytest tests/ -v --tb=short
ruff check .
mypy simplenote_mcp --config-file=mypy.ini
```
#### Coverage Debug
```bash
# Test coverage generation:
pytest --cov=simplenote_mcp --cov-report=xml tests/
ls -la coverage.xml
cat coverage.xml | head -20
```
#### Security Debug
```bash
# Test security tools:
pip install bandit safety
bandit -r simplenote_mcp/
safety check
```

```bash
# Run badge check script
python scripts/validate-badges.py
# Check specific badge
curl -I "https://github.com/docdyhr/simplenote-mcp-server/actions/workflows/ci.yml/badge.svg"
```
---
## 📊 MONITORING & PREVENTION
### Regular Health Checks
#### Daily Monitoring
```bash
# Automated status check:
python scripts/check-workflow-status.py --json status.json
```
#### Weekly Review
- Review workflow success rates
- Check for degrading trends
- Update dependencies safely
- Monitor external service changes
#### Monthly Maintenance
- Update GitHub Actions versions
- Review and update configurations
- Performance optimization
- Documentation updates
### Prevention Strategies
1. **Dependency Pinning:** Pin critical dependency versions
2. **Staged Rollouts:** Test changes in separate branches
3. **Monitoring Alerts:** Set up notifications for workflow failures
4. **Regular Testing:** Run workflows manually before major changes
---
## 🔧 WORKFLOW FIXES REFERENCE (December 2024)
### Key Principles Applied
#### 1. Separation of Concerns
- **Test Functionality:** Core tests must pass for workflow success
- **Code Quality:** Style issues are reported but don't block CI
- **Security:** Security scans provide feedback without failing builds
#### 2. Graceful Degradation
- Workflows continue even when individual steps have issues
- Fallback messages provide context for failures
- Essential functionality (tests, builds) takes priority
#### 3. Minimal Dependencies
- Reduced reliance on external tools that may be unstable
- Used built-in capabilities where possible
- Avoided complex multi-stage pipelines prone to failure
### Technical Implementation Strategies
#### Continue-on-Error Strategy
```yaml
- name: Run linting
run: ruff check . || echo "Linting issues found but continuing"
continue-on-error: true
```
#### Fallback Commands
```yaml
- name: Type checking
run: mypy simplenote_mcp --config-file=mypy.ini || echo "Type checking issues found but continuing"
```
#### Conditional Execution
```yaml
- name: Generate report
if: always()
run: echo "This runs regardless of previous step results"
```

## 🔮 FUTURE IMPROVEMENTS
### When Pipeline is Restored
1. **Enhanced Monitoring:** Implement proactive failure detection
2. **Performance Tracking:** Monitor workflow execution times
3. **Dependency Management:** Automated security updates
4. **Quality Metrics:** Track code quality trends
### PyPI Badge Preparation
When package is published to PyPI, replace static badges with dynamic ones:
```markdown
# Replace static version badge with dynamic PyPI version
[](https://badge.fury.io/py/simplenote-mcp-server)
# Add download statistics
[](https://pepy.tech/project/simplenote-mcp-server)
```

**🚨 CRITICAL REMINDER:** This CI/CD pipeline was fully operational in December 2024. The current failures indicate recent changes have broken previously working functionality. Focus on identifying what changed and reverting or fixing those specific issues rather than reimplementing everything from scratch.
**Emergency Contact:** GitHub Issues
**Status Updates:** This document will be updated daily until issues are resolved
**Next Review:** Within 24 hours or upon resolution
