File contents

GitHub Grep

Base directory for this skill: /home/hazeruno/.config/opencode/skills/gh-grep

Search for real-world code examples across over a million public GitHub repositories via grep.app.

When to Use

Finding implementation patterns for unfamiliar APIs or libraries
Looking for correct syntax, parameters, or configuration examples
Discovering production-ready code examples and best practices
Understanding how different libraries/frameworks work together

Quick Start

Run the CLI script with bun (use absolute path):

bun /home/hazeruno/.config/opencode/skills/gh-grep/scripts/grep.ts searchGitHub --query "<code-pattern>" [options]

Core Options

Option	Description
`--query`	Literal code pattern (required)
`--match-case`	Case-sensitive search
`--match-whole-words`	Match whole words only
`--use-regexp`	Interpret query as regex
`--repo`	Filter by repository (e.g., `facebook/react`)
`--path`	Filter by file path (e.g., `src/components/`)
`--language`	Filter by language (comma-separated, e.g., `TypeScript,TSX`)

Global Options

-t, --timeout <ms>: Call timeout (default: 30000)
-o, --output <format>: Output format: text | markdown | json | raw

Search Patterns

Important: This tool searches for literal code patterns, not keywords.

Good searches:

useState( - Find React useState usage
import React from - Find React import statements
async function - Find async function declarations

Bad searches:

react tutorial - Keywords, not code
best practices - Concepts, not patterns
how to use - Questions, not code

For detailed pattern examples and regex usage, see references/api_reference.md.

Common Examples

# Find Authentication Patterns
bun /home/hazeruno/.config/opencode/skills/gh-grep/scripts/grep.ts searchGitHub \
  --query "getServerSession" --language "TypeScript,TSX"

# Find Error Boundary Implementations
bun /home/hazeruno/.config/opencode/skills/gh-grep/scripts/grep.ts searchGitHub \
  --query "ErrorBoundary" --language "TSX"

# Find useEffect Cleanup with Regex
bun /home/hazeruno/.config/opencode/skills/gh-grep/scripts/grep.ts searchGitHub \
  --query "(?s)useEffect\(\(\) => {.*removeEventListener" --use-regexp true

# Find CORS Handling in Flask
bun /home/hazeruno/.config/opencode/skills/gh-grep/scripts/grep.ts searchGitHub \
  --query "CORS(" --match-case true --language "Python"

# Search Within Specific Repository
bun /home/hazeruno/.config/opencode/skills/gh-grep/scripts/grep.ts searchGitHub \
  --query "createContext" --repo "facebook/react"

Requirements

Bun runtime
mcporter package (embedded in script)
