I made tilth much for the same reasons. Its MIT licence, open source and saves you 30% token use (benchmarked)

Interesting - I've been digging into Claude Code's behavior patterns too, but from the cost side. The variance in how many API calls a task takes is wild. A simple refactoring can be 3 calls or 30 depending on codebase state. Curious what tools it suggested — did any of them relate to reducing unnecessary loops?

I'm never sure whether to believe llms about themselves.

Anthropic create developer containers with a selection of tools installed. Is that a better guide? Some of the config seems aimed at human developers but if claude likes the tools why aren't they in this list?

Interesting about the `semgrep` tool; I've never heard of it before.

The strange thing (or not) is that I have got completely different set of recommendations coming from claude.

Also; funny thing is I use mise a lot more than brew and claude could pick up on that.
