What it is
Yossi Eliaz lists Incredibuild and Islo as affiliations. The page describes a prototype inspired by Yoonho Lee's meta-harness work.
What it says
- A meta-harness is a loop where a proposer reads logs and writes a better harness.
- A simulator and hint table took five toy tasks from 0 to 5 passing.
- Step one passed 2 tasks because one hint shares a keyword with another fix.
- No model API calls were made, and the Islo sandbox integration is an unvalidated stub.
- The author says the result shows orchestration, not real-agent accuracy or generalization.
What evidence it gives
The page shows a pass-rate table, a heatmap and a dashboard sketch from the simulation. Code and a PDF writeup are linked. The fixes are written into the simulator and proposer.
Interests and limits
The author works for companies tied to the proposed runtime. The results cannot show that an LLM proposer would work. The Islo path was not validated, and the linked code and PDF were not read.
