Audit Markdown links, images, and local anchors for broken relative references. Use when reviewing documentation changes, moving or renaming assets, updating indexes, or investigating broken links.
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
# Markdown Link Auditor Verify that documentation references resolve without changing content unless the user explicitly requests fixes. ## Use this skill when - Markdown files, folders, or assets were added, moved, or renamed. - An index, README, guide, prompt, skill, workflow, or agent was changed. - A review needs evidence that local documentation references still work. ## Audit workflow 1. **Define scope.** Use the files and folders named by the user. If none are named, inspect the changed Markdown files and the nearest relevant index files. State the scope before reporting results. 2. **Reuse repository tooling.** Prefer an existing Markdown link checker or parser. Otherwise, tokenise Markdown carefully and ignore fenced code blocks and inline code unless the user asks to audit examples. 3. **Collect references.** Check inline links, reference-style links and definitions, images, and intentionally navigable autolinks. Preserve the displayed label and source location. 4. **Resolve local targets.** - Resolve relative paths from the source file's directory. - Split query or fragment identifiers from the path before checking the file. …

How to install
mdr add marielynneblock/arcanum-artifex/markdown-link-auditor@sha256:4ef2f74d24874965The line at the top of this page pins the label v1.1.0, 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.
