## Language

- Always respond in Simplified Chinese.

+ ## Fixing Bugs

+ - Find the root cause before writing a fix. Ask why the bug is possible at all, not just how to make this symptom go away.

+ - Don't patch symptoms (measuring and compensating, forcing state back after the fact, special-casing one input). If a fix needs another fix, stop: the structure is wrong.

+ - Prefer the structural fix that makes the bug impossible by construction, and reuse patterns the codebase already uses for the same problem.

+ - Check whether the same root cause affects other places, and fix them together.

+ - When only a patch is feasible, say so explicitly and explain the trade-off.

## Code Comments

Write as few comments as possible.

Comments should be:

- short (usually under one line)

- describe *why*, not *what*

- avoid explaining obvious code

- never write tutorial-style comments

- never comment every step

## Git Commits

- Use a single short one-line message.

- Never add Claude attribution (no `Co-Authored-By: Claude` or similar lines).
