Recheck due
MetaHarness is an MIT-licensed harness generator from ruvnet. It scaffolds a team-owned CLI, MCP tools, memory scope and governance configuration from a repository or template. Experimental development loops compare harness variants. Generated policies and signed provenance do not prove safe execution or better model performance; model and infrastructure costs remain separate.
- Availability
- Available. Available source and a browser Studio. The October 28 press release is not evidence of its first-ever availability.
- How to use it
- Web app; Library / CLI. Inspect source and generated configuration before installing or executing anything.
- Processing and data
- Local and cloud options. The Studio and generated runtime have different data paths; inspect generated connectors and provider configuration.
- Costs and limits
- MIT source; selected models, services and execution infrastructure cost separately.
- Outputs
- Editable harness source, CLI and policy/provenance artifacts; inspect outputs before execution or publication.
No generated harness, security control or evolution experiment was executed by ASE. Leaderboard and combined ecosystem adoption figures are omitted.
