1k tokens, google says thats about 750 words. That's actually pretty short, any chance you could post a few samples of instructions or even link to a publicly available file CLAUDE.md you recommend?
This is the meat of it:
## Code Style (See JULIA_STYLE.md for details)
- Always use explicit `return` statements
- Use Float32 for all numeric computations
- Annotate function return types with `::`
- All `using` statements go in Main.jl only
- Use `error()` not empty returns on failure
- Functions >20 lines need docstrings
## Do's and Don'ts
- Check for existing implementations first
- Prefer editing existing files
- Don't add comments unless requested
- Don't add imports outside Main.jl
- Don't create documentation unless requested
Since Opus 4.0 this has been enough to get it to write code that generally follows our style, even in Julia, which is a fairly niche language.
