Use when about to refactor or refine a user-level or project-level CLAUDE.md or AGENTS.md, from a full restructure down to a one-line wording fix; a change that looks too small to need this skill is not an exemption.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Overview

Refactor an instruction file (`CLAUDE.md` or `AGENTS.md`). Every retained instruction competes for attention in the sessions that load it.

The file serves every agent and model that reads it, not only this session's. The filename does not say who reads it, since Claude Code reads `AGENTS.md` too. Each reader assembles its own system prompt, so a line that restates one reader's prompt can be the only copy for another. Audit each line against every reader.

## Instructions

Use `AskUserQuestion` in Claude Code or `request_user_input` in Codex when available.

1. **Pick the target and its readers.** If the invocation names a file, use it. Otherwise discover candidate files using the reader platforms' loading rules in the references below, and ask only if the target remains ambiguous. Resolve the readers from the invocation and context; ask only when uncertain. Read one reference per reader platform, both when both read the file:
   - **Claude models:** [references/claude-code.md](references/claude-code.md) for which files load and when, its guides, its system-prompt probe, and its demote destinations.
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add vinta/hal-9000/refactor-agents-md@sha256:e31c02fbb6821506

The line at the top of this page pins the label git:20261105.4b89302, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
