Everything Gemini Code

A comprehensive configuration suite for Gemini CLI / Antigravity.

This extension provides production-ready agents, skills, hooks, commands, rules, and MCP configurations designed to supercharge your development workflow with Gemini.

---

🚀 Quick Start

npm install -g @google/gemini-cli@latest

### Authentication (Required)

The Gemini CLI requires an API key to function.

1.  Get your API key from [Google AI Studio](https://aistudio.google.com/).
2.  Set it as an environment variable:

```bash
export GEMINI_API_KEY="your_api_key_here"

Or configure it using the CLI (if supported by your version):

gemini config set apiKey "your_api_key_here"

Option 1: Install via Gemini CLI (Recommended)

The easiest way to install. This will automatically set up the extension for Gemini CLI.

gemini extensions install https://github.com/Jamkris/everything-gemini-code

Option 2: Install via Script (For Antigravity & Advanced Users)

Recommended if you use Antigravity (VS Code / Cursor) or need to customize the installation. Existing configurations will be updated.

# Install for Antigravity (Recommended)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Jamkris/everything-gemini-code/main/scripts/install.sh)" -- --antigravity

# Install All (CLI + Antigravity)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Jamkris/everything-gemini-code/main/scripts/install.sh)" -- --all

Option 1: Uninstallation (Recommended)

gemini extensions uninstall https://github.com/Jamkris/everything-gemini-code

Option 2: Uninstallation (Manual Script)

# Selective Uninstall (Recommended): Removes only files installed by this extension.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Jamkris/everything-gemini-code/main/scripts/uninstall.sh)" -- --antigravity

# Full Uninstall (Caution): Deletes ALL files in the target directories.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Jamkris/everything-gemini-code/main/scripts/uninstall.sh)" -- --antigravity --purge

Option 2: Manual Installation (Advanced)

If you prefer manual control or need to customize specific components:

# Clone the repository
git clone https://github.com/Jamkris/everything-gemini-code.git

# Copy agents
cp everything-gemini-code/agents/*.md ~/.gemini/agents/

# Copy commands (Gemini CLI)
cp everything-gemini-code/commands/*.toml ~/.gemini/commands/

# Copy workflows (Antigravity)
# Note: For Antigravity, use ~/.gemini/antigravity/global_workflows/
cp everything-gemini-code/workflows/*.md ~/.gemini/antigravity/global_workflows/

# Copy skills
cp -r everything-gemini-code/skills/* ~/.gemini/skills/

For Antigravity Users: If you are manually installing for Antigravity, copying to ~/.gemini/antigravity/ subdirectories (global_agents, global_skills) is recommended for full compatibility. The install.sh script handles this automatically.

Note: Rules are bundled into ~/.gemini/GEMINI.md via install.sh. For manual installs, copy a template: cp everything-gemini-code/templates/GEMINI_GLOBAL.md ~/.gemini/GEMINI.md

### Option 3: Install as Gemini CLI Extension (Developer Mode)

You can link this repository directly to Gemini CLI as an extension. This allows you to develop and test changes in real-time.

```bash
# Clone the repository
git clone https://github.com/Jamkris/everything-gemini-code.git
cd everything-gemini-code

# Link the extension
gemini extensions link .

⚠️ Note: Rules are generated into ~/.gemini/GEMINI.md by the install script. For extension-only installs, copy a template manually: cp templates/GEMINI_GLOBAL.md ~/.gemini/GEMINI.md

---

💻 Usage

Once installed, you can access the new capabilities directly in Gemini CLI.

Slash Commands

Use custom commands to automate workflows (see Full Command List):

# Plan a feature implementation
/egc-plan "Add user authentication with JWT"

# Start Test-Driven Development workflow
/egc-tdd "Create a user service"

# Run a code review
/egc-code-review

Antigravity users: workflows are installed under bare names (e.g. /tdd, /code-review, /build-fix) — the egc- prefix is only applied to /egc-plan, which would otherwise conflict with Antigravity's built-in /plan. In Gemini CLI every command uses the egc- prefix to avoid collisions with its built-in command set.

Agents

Delegate complex tasks to specialized agents:

# Use the architect agent for system design
@architect "Design a microservices architecture for..."

# Use the security reviewer for vulnerability checks
@security-reviewer "Audit this file for injection flaws"

Skills

Gemini will automatically utilize installed skills when relevant to your request, such as "TDD Workflow" or "Backend Patterns".

MCP Servers

Configure and manage Model Context Protocol (MCP) servers to extend Gemini's capabilities. (see MCP Configuration Guide)

⚠️ Troubleshooting

If you see "Skill conflict detected" warnings, it means you have previously installed skills manually. You can safely remove the local versions to use the extension's managed skills:

# Remove manually installed skills and commands to avoid conflicts
rm -rf ~/.gemini/skills/* ~/.gemini/commands/*
