Checking that the SKILL.md file is still in the repository.

Clone and explore GitHub repositories locally for analysis. Use when the user wants to: (1) Analyze a GitHub repo's architecture or code structure (2) Search for patterns, functions, or code in a remote repo (3) Understand dependencies and entry points of a project (4) Find code hotspots, TODOs, or frequently changed files (5) Map the public API/exports of a library Triggers: "explore repo", "analyze this github repo", "search in repo", "clone and analyze", "what's in this repo", "show me the structure of", "find in github repo"

SKILL.md

Repo Explorer

Clone GitHub repositories locally and explore them with powerful search and analysis tools.

Quick Start

bash

# 1. Clone/cache the repo
./scripts/repo-clone.sh owner/repo
 
# 2. Explore structure
./scripts/repo-structure.sh owner/repo
 
# 3. Search code
./scripts/repo-search.sh owner/repo "pattern"

All repos are cached at ~/.pi-repos/ for fast subsequent access.

Available Commands

Command	Purpose
`repo-clone.sh`	Clone or update a GitHub repo
`repo-structure.sh`	Show directory tree
`repo-search.sh`	Search with ripgrep
`repo-file.sh`	Read file contents
`repo-find.sh`	Find files by pattern
`repo-deps.sh`	Analyze dependencies
`repo-hotspots.sh`	Find code hotspots
`repo-exports.sh`	Map public API exports
`repo-ast.sh`	AST structural search

Command Reference

repo-clone.sh

Clone or update a repository.

bash

repo-clone.sh <owner/repo or URL> [--refresh]
 
# Examples
repo-clone.sh vercel/next.js
repo-clone.sh https://github.com/facebook/react
repo-clone.sh git@github.com:owner/repo.git
repo-clone.sh owner/repo --refresh  # Force update

repo-structure.sh

Show directory structure.

bash

repo-structure.sh <owner/repo> [--path <subpath>] [--depth <n>]
 
# Examples
repo-structure.sh vercel/next.js
repo-structure.sh vercel/next.js --path packages/next/src --depth 3

repo-search.sh

Search code with ripgrep.

bash

repo-search.sh <owner/repo> <pattern> [--glob <glob>] [--context <n>]
 
# Examples
repo-search.sh vercel/next.js "useRouter" --glob "*.ts"
repo-search.sh facebook/react "useState" --context 5
repo-search.sh owner/repo "TODO|FIXME"

repo-file.sh

Read file contents with line numbers.

bash

repo-file.sh <owner/repo> <path> [--start <line>] [--end <line>]
 
# Examples
repo-file.sh vercel/next.js package.json
repo-file.sh owner/repo src/index.ts --start 1 --end 50

repo-find.sh

Find files by pattern.

bash

repo-find.sh <owner/repo> <pattern> [--type <f|d>] [--ext <ext>]
 
# Examples
repo-find.sh vercel/next.js "config" --type f
repo-find.sh owner/repo "test" --ext ts

repo-deps.sh

Analyze project dependencies.

bash

repo-deps.sh <owner/repo>
 
# Supports: package.json, requirements.txt, pyproject.toml,
#           go.mod, Cargo.toml, Gemfile, build.gradle, pom.xml

repo-hotspots.sh

Find code hotspots (churn, large files, TODOs).

bash

repo-hotspots.sh <owner/repo>
 
# Shows:
# - Most frequently changed files (git churn)
# - Largest files by line count
# - Files with most TODOs/FIXMEs
# - Recent commits

repo-exports.sh

Map public API and exports.

bash

repo-exports.sh <owner/repo> [--entry <path>]
 
# Examples
repo-exports.sh vercel/next.js
repo-exports.sh owner/repo --entry src/lib/index.ts

repo-ast.sh

AST-grep structural code search. See ast-patterns.md for pattern examples.

bash

repo-ast.sh <owner/repo> <pattern> [--lang <language>]
 
# Examples
repo-ast.sh owner/repo 'function $NAME($$ARGS) { $$BODY }'
repo-ast.sh owner/repo 'console.log($$_)' --lang ts
repo-ast.sh owner/repo 'useState($INIT)' --lang tsx

repo-cleanup.sh

Remove cached repositories.

bash

repo-cleanup.sh <owner/repo>  # Remove specific repo
repo-cleanup.sh --all         # Clear entire cache
repo-cleanup.sh               # List cached repos

Common Workflows

Understand a new codebase

bash

repo-clone.sh owner/repo
repo-structure.sh owner/repo --depth 3
repo-deps.sh owner/repo
repo-exports.sh owner/repo

Find specific functionality

bash

repo-clone.sh owner/repo
repo-search.sh owner/repo "authentication" --glob "*.ts"
repo-ast.sh owner/repo 'async function $NAME($$_) { $$_ }' --lang ts

Assess code quality

bash

repo-clone.sh owner/repo
repo-hotspots.sh owner/repo
repo-search.sh owner/repo "TODO|FIXME|HACK|XXX"

Analyze library API

bash

repo-clone.sh owner/repo
repo-exports.sh owner/repo
repo-file.sh owner/repo src/index.ts

Requirements

Required:

git - For cloning repositories
rg (ripgrep) - For fast code search

Optional (enhanced features):

fd - Better file finding (falls back to find)
tree - Better directory structure (falls back to find)
ast-grep / sg - Structural code search
jq - Better JSON parsing for dependencies

Install on macOS:

bash

brew install ripgrep fd tree ast-grep jq

Install on Linux:

bash

# Debian/Ubuntu
apt install ripgrep fd-find tree jq
cargo install ast-grep  # or npm i -g @ast-grep/cli
