This project was inspired by the library @tupe12334/claude.

@hammer/gpt

Install and manage Codex CLI slash command prompts for Hammer. The library copies bundled prompt markdowns into the location expected by Codex on Windows: %USERPROFILE%\\.codex\\prompts.

Installation

npm install @hammer/gpt --save-dev

You can also install the CLI globally if you prefer to run it outside a project context:

npm install -g @hammer/gpt

Usage

CLI

Run the sync command to install the prompts Codex expects on Windows. On other platforms the command is a no-op.

npx gpt sync

# or, if installed globally
gpt sync

# hammer-gpt is available as an alias
hammer-gpt sync

Programmatic

import { loadAllCommands } from "@hammer/gpt";

// Generates the command markdown in %USERPROFILE%\.codex\prompts when running on Windows.
const commands = loadAllCommands();

Adding a new command

1. Create a new file in src/commands/ exporting a CodexCommand.
2. Add the command export to allCommands in src/commands/index.ts.
3. Rebuild and run gpt sync to update the prompts directory.
