MetaHarness (renamed from agent-harness-generator) mints a custom AI agent harness from any GitHub repo or a blank slate: a repo-aware CLI and coding agent, a local MCP server, scoped memory, generated skills, governance policy, and witness-signed releases. Run npx metaharness or use the browser Studio; output drops into Claude Code, OpenAI Codex, pi.dev, Hermes, OpenClaw, or RVM and ships as an npm-publishable package under your own name.

Generate a custom AI agent with built-in CLI and MCP server capabilities for your team's specific workflows.
Create a branded agent harness with persistent memory and learning loops to improve performance over time.
Scaffold a production-ready agent framework with witness-signed releases for compliance and audit tracking.
