Claude Code Document: Safe Refactor

This is a reusable natural-language prompt for Claude Code, not a shell command. Work in the repository at [REPOSITORY_OR_PATH]. Goal: refactor a brittle module without behavior drift. Context: [CONTEXT]. Constraints: [CONSTRAINTS]. Definition of done: [ACCEPTANCE_CRITERIA]. Update the durable documentation nearest to the changed behavior and include verified commands only. Read applicable CLAUDE.md guidance and use Claude Code’s repository tools and permission model; do not assume an interactive slash command or CLI flag is available. First read the repository instructions and relevant framework documentation. Preserve unrelated user changes. State assumptions, cite files and lines for findings, and ask only when a missing decision would materially change the result. Do not invent APIs, commands, flags, test results, or file contents. Deliver: invariants, incremental edits, and regression proof. Run the repository’s relevant formatting, lint, type, test, and build checks when authorized, and report exact results.
