Modernized devcontainer setup with Claude, Codex, Antigravity, and opencode that's ready to run in YOLO mode. Pre-configured with obra/superpowers and sane defaults that persists logins, configs, and conversation history across container rebuilds. Just drop the .devcontainer/ folder into any repo and you're good to go.

Why

I found myself fighting with a swamp of configuration and long-build times every time I wanted to spin up a devcontainer for agentic coding: installing CLIs, configuring shell, setting up volumes for persistent state (like logins, conversation history, ...), and so on. It was inertia I didn't like.

What's in the box

• Coding CLIs — Claude Code, Google Antigravity (agy, gemini-cli's successor), OpenAI Codex, opencode — pre-installed with yolo-mode aliases
• Superpowers — obra/superpowers skills auto-installed for Claude, Codex, and opencode (Antigravity has no superpowers plugin yet)
• skills CLI — vercel-labs/skills package manager for agent skills — skills add <pkg> works across Claude, Codex, opencode, and more
• DeepWiki MCP — pre-wired for Claude and Codex for instant Q&A on any public GitHub repo
• Persistent state — named docker volume keeps your logins, configs, and conversation history across container rebuilds
• Shell — zsh + starship + (fd, ripgrep, fzf, eza, zoxide) + lazygit (lzg) + lazydocker (lzd)

YOLO Aliases

Alias	What it runs
cy	claude --dangerously-skip-permissions
csy	claude --dangerously-skip-permissions --model sonnet
ay	agy --dangerously-skip-permissions
xy	codex --yolo

Quickstart

1. Copy .devcontainer/ into your repo root (also works to update an existing FAFO scaffold to the latest — re-running replaces .devcontainer/, so back up any local edits first):

   rm -rf _fafo-tmp .devcontainer && \
   git clone --depth 1 https://github.com/epicwhale/fafo-devcontainer.git _fafo-tmp && \
   mv _fafo-tmp/.devcontainer . && rm -rf _fafo-tmp

2. Open in VS Code → Dev Containers: Reopen in Container

3. Start coding freely: type cy, xy, ay, or opencode

Using devcontainer cli? devcontainer up then devcontainer exec zsh.
