Code Style
Language: JavaScript
Naming Conventions
| Element | Convention |
|---|
| Files | camelCase |
| Functions | camelCase |
| Classes | PascalCase |
| Constants | SCREAMING_SNAKE_CASE |
Import Style: Relative Imports
Export Style: Mixed Style
Preferred import style
typescript
// Use relative imports
import { Button } from '../components/Button'
import { useAuth } from './hooks/useAuth'
Testing
Test Framework
No specific test framework detected — use the repository's existing test patterns.
File Pattern:
Test Types
- Unit tests: Test individual functions and components in isolation
- Integration tests: Test interactions between multiple components/services
Coverage
This project has coverage reporting configured. Aim for 80%+ coverage.
Error Handling
Error Handling Style: Try-Catch Blocks
Standard error handling pattern
typescript
try {
const result = await riskyOperation()
return result
} catch (error) {
console.error('Operation failed:', error)
throw new Error('User-friendly message')
}
Common Workflows
These workflows were detected from analyzing commit patterns.
Database Migration
Database schema changes with migration files
Frequency: ~2 times per month
Steps:
- Create migration file
- Update schema definitions
- Generate/update types
Files typically involved:
Example commit sequence:
feat: implement --with/--without selective install flags (#679)
fix: sync catalog counts with filesystem (27 agents, 113 skills, 58 commands) (#693)
feat(rules): add Rust language rules (rebased #660) (#686)
Feature Development
Standard feature implementation workflow
Frequency: ~22 times per month
Steps:
- Add feature implementation
- Add tests for feature
- Update documentation
Files typically involved:
Example commit sequence:
feat(skills): add documentation-lookup, bun-runtime, nextjs-turbopack; feat(agents): add rust-reviewer
docs(skills): align documentation-lookup with CONTRIBUTING template; add cross-harness (Codex/Cursor) skill copies
fix: address PR review — skill template (When to use, How it works, Examples), bun.lock, next build note, rust-reviewer CI note, doc-lookup privacy/uncertainty
Add Language Rules
Adds a new programming language to the rules system, including coding style, hooks, patterns, security, and testing guidelines.
Frequency: ~2 times per month
Steps:
- Create a new directory under rules/{language}/
- Add coding-style.md, hooks.md, patterns.md, security.md, and testing.md files with language-specific content
- Optionally reference or link to related skills
Files typically involved:
Example commit sequence:
Create a new directory under rules/{language}/
Add coding-style.md, hooks.md, patterns.md, security.md, and testing.md files with language-specific content
Optionally reference or link to related skills
Add New Skill
Adds a new skill to the system, documenting its workflow, triggers, and usage, often with supporting scripts.
Frequency: ~4 times per month
Steps:
- Create a new directory under skills/{skill-name}/
- Add SKILL.md with documentation (When to Use, How It Works, Examples, etc.)
- Optionally add scripts or supporting files under skills/{skill-name}/scripts/

Frequency: ~4 times per month
Steps:
- Edit SKILL.md, agent, or command files to address reviewer comments
- Update examples, headings, or configuration as requested
- Iterate until all review feedback is resolved

Best Practices
Based on analysis of the codebase, follow these practices:
Do
- Use conventional commit format (feat:, fix:, etc.)
- Follow *.test.js naming pattern
- Use camelCase for file names
- Prefer mixed exports
Don't
- Don't write vague commit messages
- Don't skip tests for new features
- Don't deviate from established patterns without discussion
