A local-first AI agent harness. Just one file — no setup mess, no cloud account, nothing leaving your laptop. You describe what you want, AI fills it in, and the agent runs on your machine.
Files, web, search, knowledge, skills, sandbox — and more. All in the box.
Plug in tools for GitHub, files, databases, Slack, and dozens more — using the open MCP standard.
Risky scripts run in an isolated box — no network, locked to your folder.
Big tasks split into smaller ones. Each subagent works on its piece, then reports back.
Teach the agent new tricks. Drop a folder into ./skills/ and the agent picks it up automatically.
Pour in articles, papers, links. The agent compiles a wiki that gets richer every run.
Missing a tool? The agent writes one for itself — sandboxed, on the fly.
Free local AI (Ollama) or cloud (OpenAI, Anthropic, Google). Switch with one flag.
Run Claude Code through Ollama, then run the agents it builds on the same machine. No API keys required for local mode. No cloud account. Nothing leaving your network.

Any of these can build the agent file. Pick the assistant you like, then point it at the same local harness.
Anthropic's agentic coding tool. Use it from the CLI, IDE, desktop app, or browser. Can be launched through Ollama for local model workflows.
Fast, capable coding sessions for broad agent-building work. Use Codex in the app, CLI, IDE, or cloud, then point it at the same local harness.
Useful when you want a Google-account path into agent building. Same prompt loop, same files, same local Agent Builder target.
