Agent Guidelines for everything-opencode

Project Overview

This repository contains the everything-opencode project. Agents should analyze the codebase structure before making changes to understand the technology stack and conventions.

Build System

Common Commands

• Build: npm run build or yarn build (check package.json)
• Development server: npm run dev or yarn dev
• Production build: npm run build:prod or yarn build:prod
• Clean: npm run clean or rm -rf dist/ build/

Linting & Formatting

• Lint: npm run lint or yarn lint
• Format: npm run format or yarn format
• Type checking: npm run typecheck or yarn typecheck
• Auto-fix: npm run lint:fix or yarn lint:fix

Testing

• All tests: npm test or yarn test
• Single test: npm test -- --testNamePattern="test name" or yarn test --testNamePattern="test name"
• Watch mode: npm run test:watch or yarn test:watch
• Coverage: npm run test:coverage or yarn test:coverage
• E2E tests: npm run test:e2e or yarn test:e2e

Code Style Guidelines

Import Organization

1. External dependencies first (React, libraries)
2. Internal modules (components, utilities, types)
3. Styles/CSS modules (if applicable)
4. Assets (images, fonts)

Example:

import React from 'react';
import { useState } from 'react';
import { Button } from '@/components/ui';
import { formatDate } from '@/lib/utils';
import styles from './Component.module.css';
import logo from './logo.png';

Formatting Rules

• Indentation: 2 spaces (check .editorconfig)
• Line length: 80-100 characters (check .prettierrc)
• Semicolons: Required (check TypeScript config)
• Quotes: Single quotes for JS, double for JSX (check .prettierrc)
• Trailing commas: ES5 style (check .prettierrc)

TypeScript Conventions

• Explicit types: Use explicit return types for functions
• Interfaces vs Types: Use interfaces for object shapes, types for unions/aliases
• Any avoidance: Avoid any type; use unknown or proper typing
• Optional chaining: Use ?. for optional properties
• Nullish coalescing: Use ?? for default values

Naming Conventions

• Files: kebab-case for components, PascalCase for React components
• Variables: camelCase
• Constants: UPPER_SNAKE_CASE
• Functions: camelCase, descriptive verbs
• Classes: PascalCase
• Interfaces/Types: PascalCase, often prefixed with 'I' (check existing code)
• Components: PascalCase, descriptive names

Error Handling

1. Try/catch: Use for async operations and expected failures
2. Error boundaries: Use React Error Boundaries for UI errors
3. Custom errors: Create specific error classes when needed
4. Logging: Use structured logging with context
5. User feedback: Provide clear error messages to users

Component Patterns

• Functional components: Prefer over class components
• Hooks: Use custom hooks for reusable logic
• Props destructuring: Destructure props at function signature
• Default props: Use default parameters or defaultProps
• Prop types: Use TypeScript interfaces for props

State Management

• Local state: useState for component-specific state
• Global state: Context API or Zustand/Redux (check existing patterns)
• Server state: React Query/SWR for API data
• Form state: React Hook Form or Formik (check existing usage)

File Structure

• Components: /src/components/ organized by feature
• Pages/Views: /src/pages/ or /src/views/
• Utils: /src/lib/ or /src/utils/
• Types: /src/types/ or type definitions with components
• Styles: CSS modules or styled-components (check existing)
• Tests: Co-located with components or in /__tests__/

Agent Workflow

Before Making Changes

1. Analyze codebase: Understand existing patterns and conventions
2. Check package.json: Identify dependencies and scripts
3. Review similar files: Look at existing implementations
4. Run tests: Ensure existing functionality works

During Implementation

1. Follow existing patterns: Match code style and architecture
2. Write tests: Add unit tests for new functionality
3. Update documentation: Update README or comments if needed
4. Keep commits focused: One logical change per commit

After Implementation

1. Run linting: npm run lint or equivalent
2. Run type checking: npm run typecheck or equivalent
3. Run tests: npm test or equivalent
4. Build verification: npm run build to ensure no errors

Special Instructions

Git Practices

• Commit messages: Use conventional commits format
• Branch naming: feature/, fix/, docs/, refactor/
• PR descriptions: Include context, changes, and testing steps

Security Considerations

• Never commit secrets: Check for .env, API keys, credentials
• Input validation: Validate all user inputs
• Dependency updates: Keep dependencies current
• Code scanning: Run security scans if available

Performance Guidelines

• Memoization: Use React.memo, useMemo, useCallback appropriately
• Code splitting: Implement lazy loading for large components
• Bundle analysis: Check bundle size impact of changes
• Optimize renders: Avoid unnecessary re-renders

Language Implementation Standardization (Completed)

Overview

All 6 programming languages now follow the same JavaScript/TypeScript pattern for consistency and maintainability:

1. JavaScript/TypeScript (Reference implementation)
2. Go (9 commands)
3. Elixir (10 commands)
4. Python (10 commands)
5. C# (10 commands)
6. Rust (10 commands)

Standardized Architecture Pattern

Each language follows this exact structure:

1. Configuration Wizard (languages/[lang]/config-wizard.js)

class LangConfigWizard {
  constructor(projectPath = process.cwd()) {
    this.projectPath = projectPath;
    this.toolDetector = new LangToolDetector();
    this.detectedTools = null;
  }

  async runWizard(options = {}) {
    // 1. Detect tools
    // 2. Show environment report
    // 3. Detect project type
    // 4. Configure project
    // 5. Save configuration
    // 6. Show next steps
  }
}

2. Tool Detector (languages/[lang]/tool-detector.js)

class LangToolDetector {
  constructor() {
    this.tools = ['tool1', 'tool2', 'tool3'];
  }

  async detectTools() {
    // Detect each tool
    // Return detected tools object
  }

  generateEnvironmentReport(detectedTools) {
    // Generate comprehensive environment report
  }
}

3. Command Runner (scripts/[lang]/command-runner.js)

class LangCommandRunner {
  constructor(projectPath = process.cwd()) {
    this.projectPath = projectPath;
    this.configManager = new ConfigManager(projectPath);
    this.toolDetector = new LangToolDetector();
    this.config = null;
    this.langConfig = null;
    this.detectedTools = null;
  }

  async initialize() {
    // 1. Validate project type
    // 2. Load configuration
    // 3. Detect tools
  }

  async runSecurityScan(options = {}) {
    // Run security scanning tools
  }

  // Other methods: runTests, runLint, runFormat, etc.
}

4. Command Files (scripts/commands/[lang]-*.js)

• [lang]-setup.js - Configuration wizard
• [lang]-test.js - Testing
• [lang]-lint.js - Linting
• [lang]-format.js - Formatting
• [lang]-deps.js - Dependency management
• [lang]-security.js - Security scanning
• [lang]-run.js - Running applications
• [lang]-clean.js - Cleaning artifacts
• [lang]-build.js - Building (if applicable)
• [lang]-typecheck.js - Type checking (if applicable)

Security Implementation Pattern

All languages implement security scanning with this pattern:

// In command runner
async runSecurityScan(options = {}) {
  const securityTools = this.langConfig.securityTools || ['default-tool'];
  const results = [];

  for (const tool of securityTools) {
    try {
      const command = this.buildSecurityCommand(tool, options);
      await this.executeCommand(command, options);
      results.push({ tool, success: true });
    } catch (error) {
      results.push({ tool, success: false, error: error.message });
    }
  }

  return results;
}

// Security command file
async function main() {
  const runner = new LangCommandRunner();
  const results = await runner.runSecurityScan(options);
  // Show results and exit with appropriate code
}

Command Count by Language

Language	Commands	Security Tools	Status
JavaScript	9+	Reference	✅ Complete
Go	9	gosec, govulncheck	✅ Complete
Elixir	10	hex.audit, mix_audit, sobelow	✅ Complete
Python	10	bandit, safety, pip-audit	✅ Complete
C#	10	dotnet list package, SecurityCodeScan	✅ Complete
Rust	10	cargo-audit, cargo-deny, cargo-geiger	✅ Complete

Documentation

Each security command has comprehensive documentation:

• commands/[lang]-security.md - Security scanning documentation
• Includes installation, usage, examples, CI/CD integration

Testing

All implementations pass integration tests:

• Command runners load successfully
• Error handlers integrated
• Security scanning implemented
• File structure validated

Benefits of Standardization

1. Consistency: Same patterns across all languages
2. Maintainability: Easy to add new languages
3. Developer Experience: Familiar patterns for users
4. Testing: Consistent test patterns
5. Documentation: Standardized documentation structure

Adding New Languages

To add a new language, follow this pattern:

1. Create languages/[newlang]/config-wizard.js
2. Create languages/[newlang]/tool-detector.js
3. Create scripts/[newlang]/command-runner.js
4. Create command files in scripts/commands/[newlang]-*.js
5. Create documentation in commands/[newlang]-security.md
6. Update test integration

Next Steps for Language Development

1. Additional Languages: PHP, Ruby, Java, etc.
2. Enhanced Security: More security tools per language
3. Performance Optimization: Benchmark and optimize
4. UI/UX Improvements: Better user interfaces
5. Integration Testing: More comprehensive test suites

Status: 100% Complete - All 6 languages have full feature parity following JavaScript/TypeScript pattern.
