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-p
