What we find when agents run again
Dated notes on how AI agents behave across repeated runs and model changes. Each one names its data and can be rebuilt from public code.
- Note three. What changes in your agent when its model is upgraded? Claude Code, Opus 5 to Opus 5.5.
- Note two. One coding agent across five models, and one model in five harnesses, and what moved.
- Note one. What repeated runs of a customer-service agent show that a single pass rate hides.
