Their lines "A meta-harness is the loop that improves the harness automatically" and "the bottleneck is diagnostic context: most optimizers compress prior runs into summary statistics, while meta-harness gives the proposer up to 10M tokens of raw execution traces to grep through," seem good, no?

Have to dig into the code, but it looks like they have sound engineering around a "self-improving" agentic coding harness. Will be fun to take the code for a spin.

I find it fascinating, all these attempts are goldmining LLMs with a harness and it's clear they're generating all the docs for AI to read and use, even the docs say "we made a MCP for this!" like some how within 2 years people no longer make choices and it's just like AIs roaming the internet trying on harnesses, etc; certainly that'd be a fascinating reality but the verbosity really is a eye-glazing experience. Who do they expect to read all of that ad copy? It's not me.
