Code Style

Language: JavaScript

Naming Conventions

Import Style: Relative Imports

Export Style: Mixed Style

Preferred import style

// 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.js

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

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:

1. Create migration file
2. Update schema definitions
3. Generate/update types

Files typically involved:

• **/schema.*
• migrations/*

Example commit sequence:

feat: implement --with/--without selective install flags (#679)

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:

1. Create a new directory under rules/{language}/
2. Add coding-style.md, hooks.md, patterns.md, security.md, and testing.md files with language-specific content
3. Optionally reference or link to related skills

Files typically involved:

• rules/*/coding-style.md

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:

1. Create a new directory under skills/{skill-name}/
2. Add SKILL.md with documentation (When to Use, How It Works, Examples, etc.)
3. Optionally add scripts or supporting files under skills/{skill-name}/scripts/
4. Address review feedback and iterate on documentation

Files typically involved:

• skills/*/SKILL.md
• skills/*/scripts/*.sh
• skills/*/scripts/*.js

Example commit sequence:

Create a new directory under skills/{skill-name}/
Add SKILL.md with documentation (When to Use, How It Works, Examples, etc.)

Add New Agent

Adds a new agent to the system for code review, build resolution, or other automated tasks.

Frequency: ~2 times per month

Steps:

1. Create a new agent markdown file under agents/{agent-name}.md
2. Register the agent in AGENTS.md
3. Optionally update README.md and docs/COMMAND-AGENT-MAP.md

Add New Workflow Surface

Adds or updates a workflow entrypoint. Default to skills-first; only add a command shim when legacy slash compatibility is still required.

Frequency: ~1 times per month

Steps:

1. Create or update the canonical workflow under skills/{skill-name}/SKILL.md
2. Only if needed, add or update commands/{command-name}.md as a compatibility shim

Address Review Feedback

Addresses code review feedback by updating documentation, scripts, or configuration for clarity, correctness, or convention alignment.

Frequency: ~4 times per month

Steps:

1. Edit SKILL.md, agent, or command files to address reviewer comments
2. Update examples, headings, or configuration as requested
3. 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
