history

Project history and usage

tweakcc is a Piebald-AI CLI for customizing and patching Claude Code installations.

Project history

The official GitHub repository was created in July 2025. The README describes a tool that patches Claude Code's packaged JavaScript to customize system prompts, themes, toolsets, spinners, input styling, and other behavior.

The 4.x documentation adds an API, sandboxed custom patch scripts, remote config application, AGENTS.md support, and native-binary unpacking and repacking across macOS, Windows, and Linux.

Adoption history

The README emphasizes package-manager-first use through `npx tweakcc` and `pnpm dlx tweakcc`, and supports Claude Code installations made with npm, yarn, pnpm, bun, Homebrew, Nix, and multiple runtime managers. source_facts.package-manager also records a Homebrew formula.

How it is used

Typical use is `npx tweakcc` for the interactive interface or `npx tweakcc --apply` to reapply stored customizations. Advanced users can use `unpack`, `repack`, and `adhoc-patch` to inspect or modify packaged Claude Code JavaScript.

Why package nerds care

tweakcc applies package tooling to customization of another packaged developer tool: npx is the entry point, a home-directory JSON file stores state, and patch scripts can be distributed and automated.
