A devcontainer that bundles four AI coding agents — Claude Code, GitHub Copilot CLI, OpenCode, and Codex — with Pulumi, Kubernetes tooling, and 29 agent skills, 12 agents, 5 hooks, and 4 MCP servers powered by yaah. Open it in VS Code (or any devcontainer-compatible editor) and you get a ready-to-go environment for building cloud infrastructure with AI assistance.

Coding agents: Claude Code, GitHub Copilot (VS Code extension + CLI), OpenCode, Codex

Languages: Node.js, Python, Go (all latest)

Infrastructure tools: kubectl, Helm, GitHub CLI

Linters and language servers: Ruff, golangci-lint, gopls, Prettier, Pyright, TypeScript language server

Agent harness: yaah v0.2.2 — generates skills, agents, hooks, and MCP server config for all four agents via yaah generate. See docs/tools-and-skills.md for the full list.

• Docker (or a compatible container runtime)
• VS Code with the Dev Containers extension, or another devcontainer-compatible tool (GitHub Codespaces, DevPod, etc.)

1. Clone the repo:

git clone https://github.com/dirien/devcontainer-coding-agents.git
cd devcontainer-coding-agents

2. Open in VS Code and reopen in container when prompted (or run Dev Containers: Reopen in Container from the command palette).

3. Authenticate whichever agents you want to use:

# Claude Code — OAuth (port 19999 is pre-forwarded)
claude auth login --callback-port 19999

# GitHub Copilot CLI
copilot /login

# OpenCode
opencode auth login

# Codex — set OPENAI_API_KEY env var

4. Start building.

Set these on your host machine before opening the container, or pass them through your devcontainer tooling. They get forwarded into the container automatically.

Claude Code configuration is stored in a Docker volume (claude-config) mounted at /home/vscode/.claude, so your settings survive container rebuilds.

Edit .devcontainer/devcontainer.json to add or remove features, skills, tools, or port forwards. The postCreateCommand section runs once when the container is first built; postStartCommand runs on every start.
