codemap — a project brain for your AI. Give LLMs instant architectural context without burning tokens.

# macOS/Linux
brew tap JordanCoin/tap && brew install codemap
# Windows
scoop bucket add codemap https://github.com/JordanCoin/scoop-codemap
scoop install codemap

Other options: Releases | go install | Build from source

codemap .                    # Project tree
codemap --only swift .       # Just Swift files
codemap --exclude .xcassets,Fonts,.png .  # Hide assets
codemap --depth 2 .          # Limit depth
codemap --diff               # What changed vs main
codemap --deps .             # Dependency flow

Smart pattern matching — no quotes needed:

• .png → any .png file
• Fonts → any /Fonts/ directory
• *Test* → glob pattern

See what you're working on:

codemap --diff
codemap --diff --ref develop

Powered by ast-grep. Install via brew install ast-grep for --deps mode.

Hooks (Recommended) — Automatic context at session start, before/after edits, and more. → See docs/HOOKS.md

MCP Server — Deep integration with 7 tools for codebase analysis. → See docs/MCP.md

CLAUDE.md — Add to your project root to teach Claude when to run codemap:

cp /path/to/codemap/CLAUDE.md your-project/

• Diff mode, Skyline mode, Dependency flow
• Tree depth limiting (--depth)
• File filtering (--only, --exclude)
• Claude Code hooks & MCP server
• Enhanced analysis (entry points, key types)
