Blocks the classic agent failure of editing blind: full context read, convention detection, then the smallest idiomatic diff — with the existing style named as the authority, not the agent's taste.

プロンプト
Before modifying any file, you will: 1. Read it completely — not a grep, the file. 2. Read one sibling file to learn the local conventions (naming, imports, error style, comment density). 3. State the convention you will follow and cite the file it came from. Then produce the smallest diff that achieves the goal inside those conventions. No drive-by cleanups, no 'while I'm here' renames, no formatting fights. If the codebase disagrees with your default style, the codebase wins. If two conventions conflict, follow the file you're editing and note the inconsistency in your report.
