# Everything Gemini Code
[](https://github.com/Jamkris/everything-gemini-code/stargazers)
[](LICENSE)
**Battle-tested agents, skills, and workflows for Gemini CLI / Antigravity.**
Ports 183 skills and 48 agents from [Everything Claude Code](https://github.com/affaan-m/everything-claude-code), retuned for Gemini's tool model. Adds Gemini-native features like `/egc-grok` — a whole-repo audit that uses Gemini's 1M context window in a single pass (Claude Code's 200K can't).
---
## What you can do
- **Audit your whole repo in one pass** — `/egc-grok` uses Gemini's 1M context to map architecture, find dead files, detect circular deps. No file-by-file scrolling.
- **Plan-before-code workflow** — `@planner` returns a phased breakdown with risks and dependencies. WAITs for your confirm before writing anything.
- **Test-driven feature flow** — `/egc-tdd` + `@tdd-guide` enforce write-tests-first with 80%+ coverage.
- **Security review on demand** — `@security-reviewer` flags OWASP top 10, hardcoded secrets, injection risks before commit.
- **183 skills, on-demand** — Clean Architecture, MCP, Remotion, Django, x402 payments, and more. Loaded only when referenced.

## Quick Start
```bash
gemini extensions install https://github.com/Jamkris/everything-gemini-code
```
That's it. No clone, no symlinks. Requires `GEMINI_API_KEY` in your environment ([get one from Google AI Studio](https://aistudio.google.com/)):
```bash
export GEMINI_API_KEY="your_api_key_here"
```
<details>
<summary><strong>Other install methods (Antigravity, manual, dev mode, uninstall)</strong></summary>
### Install via Script (Antigravity / advanced)
Recommended if you use **Antigravity** (VS Code / Cursor) or need to customize the installation. Existing configurations will be updated.
```bash
# Antigravity only
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Jamkris/everything-gemini-code/refs/tags/v1.3.12/scripts/install.sh)" -- --antigravity
# CLI + Antigravity
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Jamkris/everything-gemini-code/refs/tags/v1.3.12/scripts/install.sh)" -- --all
```
### Manual installation
```bash
git clone https://github.com/Jamkris/everything-gemini-code.git
# Copy agents, commands, skills
cp everything-gemini-code/agents/*.md ~/.gemini/agents/
cp everything-gemini-code/commands/*.toml ~/.gemini/commands/
cp -r everything-gemini-code/skills/* ~/.gemini/skills/
# Antigravity workflows (optional)
cp everything-gemini-code/workflows/*.md ~/.gemini/antigravity/global_workflows/
```
> **For Antigravity users:** copying to `~/.gemini/antigravity/` subdirectories (`global_agents`, `global_skills`) is recommended for full compatibility. `install.sh` handles this automatically.
>
> **Rules:** Bundled into `~/.gemini/GEMINI.md` by `install.sh`. For manual installs, copy a template: `cp everything-gemini-code/templates/GEMINI_GLOBAL.md ~/.gemini/GEMINI.md`
### Developer mode (link instead of copy)
For developing or contributing to this extension:
```bash
git clone https://github.com/Jamkris/everything-gemini-code.git
cd everything-gemini-code
gemini extensions link .
```
### Uninstall
```bash
# Extension install
gemini extensions uninstall https://github.com/Jamkris/everything-gemini-code
# Script-based install (Antigravity only — selective)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Jamkris/everything-gemini-code/refs/tags/v1.3.12/scripts/uninstall.sh)" -- --antigravity
# Script-based install (CLI + Antigravity — selective)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Jamkris/everything-gemini-code/refs/tags/v1.3.12/scripts/uninstall.sh)" -- --all
# Script-based install (Antigravity, full — deletes everything in target dirs)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Jamkris/everything-gemini-code/refs/tags/v1.3.12/scripts/uninstall.sh)" -- --antigravity --purge
```
> **Why the pinned tag?** `curl | bash` from a moving branch is reproducibility- and supply-chain-unsafe. The URLs above point at the `v1.3.12` release tag. To check what's running, view the script at <https://github.com/Jamkris/everything-gemini-code/blob/v1.3.12/scripts/install.sh> before executing.

## 💻 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](docs/en/commands/README.md)):
```bash
# 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:
```bash
# 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](docs/en/mcp-configs/README.md))

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