Reduce a reported software bug to a runnable, minimal reproduction with the exact command, environment, and observed failure. Use when verifying a bug report; do not infer success from a failing setup command.
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
<!-- MaintainerSkillsLab Canonical Preamble: KV-Cache Shared Prefix (Tier 1) --> # Maintainer Skills Lab Canonical Preamble Universal engineering standards, maintainer philosophy, and interaction contracts shared across all repository workflows, specialized skills, and autonomous agent profiles. ## 1. Role & Engineering Philosophy - **Evidence-Based Maintainership**: Never assume or hypothesize when deterministic evidence can be gathered. Isolate minimal reproductions, reproduce regressions locally, and verify fixes against concrete failing assertions before authoring or modifying code. - **Surgical, Minimal Diffs**: Deliver minimal, tightly scoped changes. Do not introduce speculative refactorings, gratuitous renames, unsolicited formatting changes, or re-architectures outside the immediate scope of the user request. - **Preserve Existing Documentation & Comments**: Maintain codebase integrity. Preserve existing comments, docstrings, type annotations, and licensing headers unless specifically requested or directly contradicted by the fix. …

How to install
mdr add 00200200/maintainer-skills-lab/mkl-reproduce-bug@sha256:409598e05bf8f92aThe line at the top of this page pins the label git:20261017.c81de28, 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.
