Claude Code Document: Safe Refactor

What this prompt does

Refactor a brittle module without behavior drift with repository-aware safeguards. It is designed for safe refactor and works best with Current Claude Code model configured for the repository.

Customize and copy

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.

How to use it

Replace the bracketed variables with real context for safe refactor. Attach or paste source material when available, and verify consequential facts before acting.

Example input

Provide a real safe refactor brief with the audience, goal, constraints, preferred format, and any available source material filled into the prompt’s placeholders.

Sample output

Refactor a brittle module without behavior drift with repository-aware safeguards. The finished response should apply that result to safe refactor, follow the requested structure, distinguish supplied facts from inference, and end with usable next actions.

Quality checklist

• The response directly addresses the safe refactor goal and intended audience.
• Every requested section or output format is present and materially complete.
• Unsupported facts are removed, sourced, or clearly marked for verification.
• The final result is specific enough to use without guessing what happens next.

Limitations and review notes

Run generated code in an isolated branch, review the diff, and execute the repository test suite before merging.

This page records an editorial structure and safety review, not a guarantee that every provider or model version will produce the same result. See the Promptle testing methodology.
