ggcode

ggcode is an AI coding agent for the terminal. It can understand a codebase, edit files, run commands, manage checkpoints, connect to MCP tools, and keep working inside a polished TUI instead of bouncing between scripts and browser tabs.

If you want a terminal-native coding workflow that feels like a product, not a demo, this is what ggcode is for.

Why people use ggcode

• Stay in the terminal — chat, inspect code, edit files, review diffs, and manage sessions in one place
• Work with real coding plans and endpoints — OpenAI-compatible, Anthropic-compatible, Gemini, and multiple coding-oriented vendor presets
• Keep control when it matters — supervised, plan, auto, bypass, and autopilot modes let you choose how much the agent can do
• Recover quickly — undo file changes with checkpoints instead of manually repairing bad edits
• Scale up when needed — use MCP tools, plugins, skills, memory, background commands, and sub-agents
• Fit daily usage — bilingual UI, resumable sessions, queueing while the agent is busy, and shell-friendly install flows

Installation

Go installer

go install github.com/topcheer/ggcode/cmd/ggcode-installer@latest
ggcode-installer

The installer downloads the matching GitHub Release binary into GOBIN, the first GOPATH/bin, or ~/go/bin.

npm

npm install -g @ggcode-cli/ggcode

The npm wrapper downloads the latest ggcode GitHub Release by default. Set GGCODE_INSTALL_VERSION if you need to pin a specific release.

pip

pip install ggcode

The Python wrapper also downloads the latest ggcode GitHub Release by default and respects GGCODE_INSTALL_VERSION for explicit pinning.

Native package files from GitHub Releases

Each tagged release now also publishes native installer/package files across desktop and Linux:

Platform	Release asset	Install example
macOS	.pkg	sudo installer -pkg ./ggcode_<version>_darwin_universal.pkg -target /
Windows	.msi	msiexec /i .\ggcode_<version>_windows_x64.msi
Debian / Ubuntu	.deb	sudo dpkg -i ./ggcode_<version>_linux_<arch>.deb
Fedora / RHEL / openSUSE	.rpm	sudo rpm -i ./ggcode-<version>-1.<arch>.rpm
Alpine	.apk	sudo apk add --allow-untrusted ./ggcode-<version>-r1.<arch>.apk
OpenWrt / opkg	.ipk	opkg install ./ggcode_<version>_<arch>.ipk
Arch Linux	.pkg.tar.zst	sudo pacman -U ./ggcode-<version>-1-<arch>.pkg.tar.zst

If you prefer not to install from a package manager, the existing release archives, Go installer, npm wrapper, and Python wrapper remain available.

Build from source

git clone https://github.com/topcheer/ggcode.git
cd ggcode
go build -o ggcode ./cmd/ggcode
./ggcode

Platform notes

• macOS / Linux command execution uses sh
• Windows command execution prefers Git Bash and falls back to PowerShell
• Shell completions are available for bash, zsh, fish, and PowerShell

Quick start

1. Set up a model endpoint

The simplest path is still setting a normal vendor API key:

export ZAI_API_KEY="your-key"
# or OPENAI_API_KEY / ANTHROPIC_API_KEY / GEMINI_API_KEY / OPENROUTER_API_KEY / ...

If you use an Anthropic-compatible endpoint, ggcode can also bootstrap it on first launch from:

export ANTHROPIC_BASE_URL="https://your-endpoint"
export ANTHROPIC_AUTH_TOKEN="your-token"

2. Start ggcode

ggcode

On first launch, ggcode asks you to choose your preferred UI language.

3. Start with a real task

Examples:

Explain how this project is structured
Refactor the auth middleware to use JWT
Add tests for the session store
Find why startup feels slow in the TUI

4. Use the built-in workflow features

• Ctrl+C cancels the active run
• If the agent is busy, you can keep typing — new prompts are queued
• /undo reverts the last file edit
• /provider switches vendor / endpoint / model
• /mode changes how much autonomy the agent gets
• /mcp shows connected MCP servers and their tools

What ggcode can do

From the product point of view, ggcode is more than “chat with a model”:

• Code understanding — read files, search the repo, inspect git status and diffs
• Code changes — create files, edit targeted regions, and checkpoint edits for undo
• Command execution — run foreground commands or long-running background jobs
• Parallel help — spawn sub-agents and inspect their progress
• Memory and context — load project memory files like GGCODE.md, AGENTS.md, CLAUDE.md, and COPILOT.md
• Extensibility — connect MCP servers, custom plugins, and skills
• Session continuity — save, resume, export, and compact conversations

Modes: how much freedom the agent gets

Mode	Best for	What it means
supervised	Most users	Ask when a tool is not explicitly allowed or denied
plan	Safe exploration	Read-only style investigation; blocks writes and command execution
auto	Faster routine work	Automatically proceed on safer actions, stay cautious on risky ones
bypass	High-trust workflows	Allow almost everything, only stopping on critical operations
autopilot	Power users	Like bypass, but also keeps going when the model would normally stop to ask

Slash commands you will actually use

Core workflow

Command	What it does
/help or /?	Show the in-app help
/provider [vendor]	Open the provider manager and switch vendor / endpoint / model
/model <name>	Switch model directly
/mode <mode>	Change permission mode
/status	Show current status
/config	View or update configuration
`/lang <en	zh-CN>`

Session and recovery

Command	What it does
/sessions	List saved sessions
/resume <id>	Resume a previous session
/export <id>	Export a session to Markdown
/clear	Clear the current conversation
/compact	Compress conversation history
/undo	Revert the last file edit
/checkpoints	List available edit checkpoints

Extended capabilities

Command	What it does
/mcp	Inspect MCP servers and MCP tools
/plugins	List loaded plugins
/skills	Browse available skills
/memory	Inspect stored memory
/agents	List active sub-agents
/agent <id>	Inspect a sub-agent
/todo	View or manage todo state
/image	Attach an image
/bug	Report a bug
/init	Generate GGCODE.md for the current project
/fullscreen	Toggle fullscreen mode
/exit, /quit	Exit ggcode

Non-interactive and scripted usage

ggcode also supports a simple pipe-mode workflow when you do not want to open the TUI:

ggcode \
  --prompt "Summarize the changes in this repository" \
  --allowedTools read_file \
  --output summary.md

Useful flags:

• --prompt / -p — run a non-interactive prompt
• --allowedTools — restrict which tools are allowed in pipe mode
• --output — write the answer to a file instead of stdout
• --bypass — start in bypass mode
• --resume <id> — resume a previous session immediately
• --config <path> — use a specific config file

Configuration

Most users only need a small config file:

vendor: zai
endpoint: cn-coding-openai
model: glm-5-turbo
language: en
default_mode: supervised

allowed_dirs:
  - .

tool_permissions:
  read_file: allow
  search_files: allow
  run_command: ask
  write_file: ask

ggcode ships with built-in presets for mainstream vendors and several coding-oriented endpoints, so you usually start by choosing a vendor or setting API keys rather than writing the full provider catalog yourself.

For the complete reference, examples, vendor catalog, hooks, MCP servers, plugins, and sub-agent settings, see:

• ggcode.example.yaml

MCP, plugins, hooks, and memory

MCP servers

Use MCP when you want ggcode to access external tool ecosystems.

mcp_servers:
  - name: filesystem
    command: npx
    args:
      - -y
      - "@anthropic/mcp-filesystem"
      - /path/to/allowed/dir

ggcode discovers MCP tools automatically and makes them available in the agent loop.

Plugins and skills

• Plugins add custom tools from config
• Skills add higher-level capabilities and workflows
• /skills is the easiest place to see what is currently available

Project memory

ggcode can load project guidance from files such as:

• GGCODE.md
• AGENTS.md
• CLAUDE.md
• COPILOT.md

Use these files to tell ggcode how your project works, what conventions to follow, and what to avoid.

Shell completions

# Bash
ggcode completion bash > /etc/bash_completion.d/ggcode

# Zsh
ggcode completion zsh > "${fpath[1]}/_ggcode"

# Fish
ggcode completion fish > ~/.config/fish/completions/ggcode.fish

# PowerShell
ggcode completion powershell | Out-String | Invoke-Expression
