• Use pnpm instead of npm when pnpm lock file exists
• Don't ask the user to run commands, just do it for yourself and analize output to continue
• No type annotations when inference works
• These principles are law: KISS, DRY and single responsibility.
• Fail fast. No fallbacks, no retry mechanisms, no silent error swallowing
• Explicit errors over defensive coding
• Strict typescript type inference only. No as assertions, no any, no ! non-null assertions
• Use satisfies over as when type typescript validation needed
• Always verify the changes work by adding an extra final task for it, dont make assumptions.
• Update your CLAUDE.md so you don't make that mistake again.
