  6. Taskmaster Integration: Complete workflow management integration

🎯 Areas for Enhancement

  1. Automation: Manual rule creation can be automated
  2. Pattern Recognition: Systematic analysis of codebase patterns
  3. Rule Quality Metrics: Track effectiveness and usage
  4. Template System: Standardized templates for new rules
  5. Maintenance Workflow: Systematic rule updates and deprecation

Implementation Roadmap

Phase 1: Foundation (Week 1)

1.1 Set Up Automation Tools

# Make scripts executable
chmod +x scripts/generate_rules.sh
chmod +x scripts/generate_cursor_rules.py

# Test the rule generator
./scripts/generate_rules.sh --analyze

1.2 Create Rule Templates Directory

# Create templates directory
mkdir -p .cursor/rules/templates

# Copy template file
cp .cursor/rules/templates/rule-templates.mdc .cursor/rules/templates/

1.3 Update Existing Rules

Review and update your existing rules to ensure they follow the enhanced structure:

# Analyze current rules
./scripts/generate_rules.sh --analyze

# Generate missing rules for specific directories
./scripts/generate_rules.sh --generate src --type python
./scripts/generate_rules.sh --generate tests --type testing

Phase 2: Automation (Week 2)

2.1 Implement Pattern Recognition

The generate_cursor_rules.py script analyzes your codebase to identify:

  • Import patterns across files
  • Function definition conventions
  • Error handling approaches
  • Testing patterns and structures
  • Naming conventions used consistently

2.2 Create Rule Generation Workflow

# Generate rules for a new feature
./scripts/generate_rules.sh --generate src/services --type python

# Generate rules for a new framework
./scripts/generate_rules.sh --generate src/web --type javascript

# Force update existing rules
./scripts/generate_rules.sh --generate --force src

2.3 Integrate with Development Workflow

Add rule generation to your development process:

# Add to your pre-commit hooks
echo "./scripts/generate_rules.sh --analyze" >> .git/hooks/pre-commit

# Add to your CI/CD pipeline
# scripts/generate_rules.sh --generate --type python src

Phase 3: Quality Assurance (Week 3)

3.1 Implement Rule Quality Metrics

Track rule effectiveness:

  • Application frequency: How often rules are applied
  • Error reduction: Impact on preventing common mistakes
  • Developer feedback: Satisfaction scores
  • Code review mentions: References in PR reviews

3.2 Create Rule Maintenance Schedule

# Weekly rule analysis
./scripts/generate_rules.sh --analyze

# Monthly rule updates
./scripts/generate_rules.sh --generate --force src tests

# Quarterly rule audit
# Review and deprecate outdated rules

3.3 Establish Rule Review Process

  1. New Rule Creation:

    • Use templates from .cursor/rules/templates/
    • Generate initial content with automation
    • Review and customize for project specifics
    • Test with actual code examples

  2. Rule Updates:

    • Monitor usage patterns
    • Gather developer feedback
    • Update based on new patterns
    • Maintain backward compatibility

  3. Rule Deprecation:

    • Identify unused or outdated rules
    • Document migration paths
    • Remove deprecated rules
    • Update references

Phase 4: Advanced Features (Week 4)

4.1 Implement Rule Dependencies

Create rule hierarchies and dependencies:

# In rule files, reference other rules
Follow [python-patterns.mdc](mdc:.cursor/rules/python-patterns.mdc) for basic Python conventions.
See [testing-patterns.mdc](mdc:.cursor/rules/testing-patterns.mdc) for test structure.

4.2 Create Domain-Specific Rule Sets

Organize rules by domain:

.cursor/rules/
├── foundational/
│   ├── cursor_rules.mdc
│   ├── self_improve.mdc
│   └── project-structure.mdc
├── language/
│   ├── python-patterns.mdc
│   ├── typescript-patterns.mdc
│   └── javascript-patterns.mdc
├── domain/
│   ├── audio-processing.mdc
│   ├── database-registry.mdc
│   └── real-file-testing.mdc
├── workflow/
│   ├── taskmaster/
│   ├── tdd.mdc
│   └── backend-first.mdc
└── templates/
    └── rule-templates.mdc

4.3 Implement Rule Versioning

Track rule changes and versions:

---
description: Python development patterns and conventions
globs: **/*.py
alwaysApply: false
version: 1.2.0
lastUpdated: 2024-01-15
---

# Python Development Rules v1.2.0

## Changelog
- v1.2.0: Added async/await patterns
- v1.1.0: Updated import organization
- v1.0.0: Initial version

Best Practices Implementation

1. Rule Content Guidelines

  • Be Specific: Rules should be actionable and specific
  • Use Real Examples: Include actual code from your codebase
  • Provide Context: Explain when and why to apply rules
  • Include Anti-Patterns: Show what NOT to do
  • Cross-Reference: Link to related rules and documentation

2. Rule Organization

  • Group by Domain: Organize rules by functionality
  • Use Consistent Naming: Follow kebab-case for filenames
  • Maintain Hierarchy: Create rule dependencies and relationships
  • Version Control: Track rule changes and updates

3. Rule Maintenance

  • Regular Reviews: Schedule periodic rule audits
  • Feedback Collection: Gather developer input on rule effectiveness
  • Pattern Monitoring: Watch for new patterns that need rules
  • Deprecation Process: Systematically remove outdated rules

4. Integration with Workflows

  • Development Process: Integrate rule generation into your workflow
  • Code Reviews: Reference rules in PR reviews
  • Onboarding: Use rules for new team member training
  • Documentation: Keep rules synchronized with project docs

./scripts/generate_rules.sh --audit

Troubleshooting

Common Issues

  1. Rule Not Applying:

    • Check globs pattern in frontmatter
    • Verify alwaysApply setting
    • Ensure rule file is in correct location

  2. Generated Rules Too Generic:

    • Customize templates with project-specific examples
    • Add domain-specific patterns
    • Include real code examples from your codebase

  3. Rule Conflicts:

    • Review rule priorities
    • Check for overlapping globs patterns
    • Resolve conflicts through rule hierarchy

  4. Performance Issues:

    • Limit rule complexity
    • Use specific globs patterns
    • Avoid overly broad alwaysApply rules
