Architecture

Project Structure: Single Package

This project uses hybrid module organization.

Configuration Files

• .github/workflows/ci.yml
• .github/workflows/maintenance.yml
• .github/workflows/monthly-metrics.yml
• .github/workflows/release.yml
• .github/workflows/reusable-release.yml

• eslint.config.js
• package.json

Guidelines

• This project uses a hybrid organization
• Follow existing patterns when adding new code

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: 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:

1. Add feature implementation
2. Add tests for feature
3. Update documentation

Files typically involved:

• manifests/*
• schemas/*
• **/*.test.*
• **/api/**

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:

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
• rules/*/hooks.md
• rules/*/patterns.md
• rules/*/security.md
• rules/*/testing.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.)
Optionally add scripts or supporting files under skills/{skill-name}/scripts/
Address review feedback and iterate on documentation

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

Files typically involved:

• agents/*.md
• AGENTS.md
• README.md
• docs/COMMAND-AGENT-MAP.md

Example commit sequence:

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