Cognitum Metaharness

Cognitum Metaharness is a factory that mints custom AI agent packages and repo-aware toolkits from any codebase.

MetaHarness is a factory for creating custom agent setups from any GitHub repository or a blank slate. It generates project-scoped memory namespaces, governance policies, MCP tools, and skills tailored to actual file layouts. The output packages as an npm-publishable zip with an npx command line interface. Users can deploy the generated toolkits to various hosts or integrate them into workflows. The system includes model routing to optimize costs, self-improving evolution modes, and evaluation tools to score repositories before building.
