“It can dispatch sub-coders, so the small model that could not finish the task alone now cannot finish it in parallel.”

“Formerly HexAgent, now UniHarness: two names, one repository, and zero downloads in the week anyone last checked.”

Which one would each critic pick
| Critic | little-coder | UniHarness | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.3 | no preference |
| El Crítico | 6.0 | 5.8 | little-coder — Correctness rests on a stack of compensations, write and read guards, output repair, thinking-budget caps and per-model profiles, each one covering for the model underneath. |
| El Profesor | 6.8 | 7.3 | UniHarness — A protocol separates the runtime from the machine it drives, and the runtime's keys, configuration and source are kept outside what the agent can read. |
| La Inversora | 5.0 | 5.3 | UniHarness — A hundred and thirty-nine stars and a corporate author, with no hosted product, no pricing and no visible commercial reason for the work to continue. |
| La Jefa | 4.8 | 5.3 | UniHarness — Free across sixty engineers and able to run unattended, but the confined remote target is a third-party service, which is a supplier my security review has to process. |
| El Hacker | 8.0 | 6.8 | little-coder — Apache-2.0, and models.json takes llama.cpp, Ollama, LM Studio, MLX or a base URL on my LAN, with a llama.cpp-served Qwen as the default. |
