Gopher AI

Cross-platform AI coding assistant toolkit for Go developers - by Gopher Guides.

Overview

Gopher AI provides skills and commands for the three major AI coding assistants:

Platform	Status	Install Method
Claude Code	Full support	Plugin marketplace
OpenAI Codex CLI	Full plugin support	Repo-local, installer script, or manual
Google Gemini CLI	Extensions	Manual install

What's included:

• 7 modules (go-workflow, go-dev, productivity, gopher-guides, llm-tools, go-web, tailwind)
• 6 auto-invoked reference skills for Go best practices, second opinions, and more
• 8 workflow skills for issue-to-PR automation (via Codex plugins and Claude Code commands)
• 20+ slash commands for development workflows

Quick Start

Install Everything (Recommended)

One command to build and install for every platform you have:

git clone https://github.com/gopherguides/gopher-ai
cd gopher-ai
./scripts/install-all.sh

This auto-detects which platforms are available (Claude Code, Codex CLI, Gemini CLI) and installs for all of them. Run it again anytime to update.

Or install from GitHub without cloning (downloads to tmp, installs, cleans up):

bash -c "$(curl -fsSL https://raw.githubusercontent.com/gopherguides/gopher-ai/main/scripts/install-all.sh)"

Updating: Just re-run ./scripts/install-all.sh from the repo (or the one-liner). It rebuilds and reinstalls everything.

Platform-Specific Install

If you only want one platform, or need first-time setup for Claude Code:

Claude Code

# 1. Add marketplace (in Claude Code)
/plugin marketplace add gopherguides/gopher-ai

# 2. Install all plugins at once (from your terminal)
~/.claude/plugins/marketplaces/gopher-ai/scripts/refresh-plugins.sh

# 3. Restart Claude Code — all 7 plugins are loaded

To install plugins individually: /plugin install go-workflow@gopher-ai, etc.

Updating: Run /productivity:gopher-ai-refresh inside Claude Code, or ./scripts/install-all.sh from the repo.

OpenAI Codex CLI

# Global install — plugins available in every Codex session, regardless of cwd.
# Easiest path (no clone needed):
bash -c "$(curl -fsSL https://raw.githubusercontent.com/gopherguides/gopher-ai/main/scripts/install-all.sh)"

# Or, if you've already cloned the repo:
git clone https://github.com/gopherguides/gopher-ai
cd gopher-ai
./scripts/install-codex.sh --user

# Repo-local install — plugins available only when running Codex inside this repo:
codex   # Plugins load automatically from .agents/plugins/marketplace.json

# Add the marketplace to another repo (project-scoped, like the gopher-ai repo itself):
./scripts/install-codex.sh --repo /path/to/your-repo

Pick one mode. --user and --repo-when-cwd'd-into-our-repo will both load the plugins, so having both active doubles the skill metadata Codex loads. The SessionStart hook on the Claude Code side auto-removes stale unmarked installs from earlier README versions and clears any stale gopher-ai marketplace cache when a marked global install is present.

Google Gemini CLI

git clone https://github.com/gopherguides/gopher-ai
cd gopher-ai
./scripts/build-universal.sh

# Install specific extensions
gemini extensions install ./dist/gemini/gopher-ai-go-dev
gemini extensions install ./dist/gemini/gopher-ai-go-workflow
# ... or any other module
