What this is
Every serious repo deserves its own agent. A repo-aware CLI, a repo-aware coding agent, a local MCP server, memory scoped to the project, skills generated from the actual file layout, governance policy, release verification, witness-signed provenance.
metaharness mints those, on demand, from a GitHub URL or a blank slate. It is not another agent framework. It is a factory for agent frameworks.
The model is replaceable. The harness is the product.
What it gives you
In under 60 seconds, in your browser, with nothing leaving your machine:
- A custom AI agent harness for your repo (or any repo)
- Recommended agents, skills, slash commands, MCP tools
- A scoped memory namespace + governance policy
- Witness-signed provenance + release gates
- Drops into Claude Code, OpenAI Codex, pi.dev, Hermes, OpenClaw, RVM, or Prime Agent — pick one or all
Output is an npm-publishable .zip with your name on it, your branding, your npx <your-name> CLI.
