Drop-in agents, commands, and skills for:

• OpenCode
• Augment CLI
• Codex CLI

This repo delivers a versioned, installable payload under opencode/, augment/, and codex/, plus cross-platform install/uninstall scripts.

Installation

Prerequisites

Install at least one of:

• OpenCode
• Augment CLI
• Codex CLI

macOS / Linux

git clone git@github.com:shanepadgett/agent-extensions.git && cd agent-extensions
./install.sh

You must run the script from the agent-extensions directory because the installer is not on your PATH. If you need to install into a different repo from its directory, reference the install script with a relative path (for example ../agent-extensions/install.sh).

Windows

git clone git@github.com:shanepadgett/agent-extensions.git; cd agent-extensions
.\install.ps1

The installer lives in the cloned repo, so run it from agent-extensions or reference it via a relative path such as ..\agent-extensions\install.ps1 when invoking from another directory.

Install Locations

Tool	Global	Local
OpenCode	~/.config/opencode/	.opencode/
Augment	~/.augment/	.augment/
Codex	~/.codex/	.codex/

Uninstall

cd agent-extensions
./uninstall.sh

cd agent-extensions
.\uninstall.ps1

If you are running the uninstall from another repo, point to the script with a relative path (for example ../agent-extensions/uninstall.sh or ..\agent-extensions\uninstall.ps1).
