What it is
tweakcc is a CLI tool that upgrades your Claude Code experience by patching the minified cli.js and applying user customizations stored in ~/.tweakcc/config.json. It supports native and npm-based installations, remote config, ad-hoc patches, and an API for creating patches.
How it works
It patches Claude Code's minified cli.js for npm-based installations. For native installations, it extracts the minified code from the binary using node-lief, patches it, and repacks the binary. Customizations are stored in ~/.tweakcc/config.json and can be reapplied with npx tweakcc --apply.
Getting started
Run without installation:
$ npx tweakcc
# Or use pnpm:
$ pnpm dlx tweakcc

Caveats
Supports both native/binary installations and npm/yarn/pnpm/bun etc. Patch applicability may be affected by Claude Code version; remote config and adhoc patches are available. The README notes that updates to Claude Code may overwrite customizations unless reapplied via config.
