Validate and fix GFM links in PR descriptions. TRIGGERS - PR links, gh pr create, GFM validation, broken PR 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
# PR GFM Link Validator
Validate and auto-convert GFM links in pull request descriptions to prevent 404 errors.
> **Self-Evolving Skill**: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
## When to Use This Skill
This skill triggers when:
- Creating a pull request from a feature branch
- Discussing PR descriptions or body content
- Mentioning GFM links, PR links, or link validation
- Using `gh pr create` or `gh pr edit`
## The Problem
Repository-relative links in PR descriptions resolve to the **base branch** (main), not the feature branch:
| Link in PR Body | GitHub Resolves To | Result |
| -------------------------- | ----------------------------- | --------------------------------- |
| `[ADR](/docs/adr/file.md)` | `/blob/main/docs/adr/file.md` | 404 (file only on feature branch) |
## The Solution
Convert repo-relative links to absolute blob URLs with the correct branch:
```
/docs/adr/file.md
↓
https://github.com/{owner}/{repo}/blob/{branch}/docs/adr/file.md
```
---
…Read the whole file at its exact version.
How to install
mdr add terrylica/cc-skills/pr-gfm-validator@sha256:d7154d04904faa96The line at the top of this page pins the label git:20261008.a4154ac, 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.
