Teach Claude your style without fine-tuning
Most "train it on my code" is one good CLAUDE.md and one example.
CLAUDE.md starter
# Project
- TypeScript strict, no `any`
- Tests next to the code: foo.ts / foo.test.ts
- No default exports
- Errors: throw AppError(code, message)
- Follow src/users/repo.ts as the example repository
# Before saying done
- pnpm typecheck && pnpm testWhen fine-tuning is right
A huge volume of the same narrow task, with thousands of labelled examples. Not "know my repo".
A new disaster and its fix every day. Comment the word under a reel to get its guide.
