Suggestion for Pi: capitalize tool names for the Sonnet/Opus models (edit -> Edit, bash -> Bash, ...).

The rationale: Anthropic's own harness (Claude Code) uses PascalCase tool names — Bash, Edit, Read, Write, Glob, Grep. Since the models are post-trained/aligned against that harness, those naming conventions are effectively baked into the model. Matching your harness's tool names to the same casing puts your inputs closer to the training distribution, which lines up with the more reliable tool use I've seen in evaling.

A related pattern that fits the same distribution: for long outputs, have the model reserve placeholders first and complete the work across multiple steps.

Pi is doing that.
