Jia-Ethan/claude-keysmith

Managed Claude Code instruction deployment with safe CLI recovery and an unsigned macOS/Windows desktop beta.

What it solves

Claude Code is an AI programming tool. claude-keysmith provides a way to inject custom, revocable instructions into Claude Code to change how it behaves in new conversations. It allows users to set specific guidelines for the AI's output and behavior without modifying the software itself or requiring account/API key access.

How it works

The tool operates as an installer for instructions. It follows a "preview-then-write" workflow: users can preview the plan of what will be changed before confirming the installation. Once installed, the instructions are applied to any new conversations started in Claude Code. These instructions can be later uninstalled (revoked) to restore the original state.

Who it’s for

Developers using Claude Code who want to customize the AI's behavior and behavior guidelines for their projects or globally, with a safety mechanism to preview changes before they are applied.

Highlights

  • Revocable Instructions: Easily install and uninstall custom instructions to switch between different AI behaviors.
  • Preview-First Workflow: Prevents accidental changes by requiring confirmation after showing a plan of the action.
  • No Software Modification: Works without altering the Claude Code binary or accessing sensitive account credentials.
  • Cross-Platform: Supports macOS, Windows, and Linux via Python 3.8+.
