80 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Validate markdown links and cross-references to ensure documentation integrity. Detects broken links, missing anchors, and invalid cross-reference paths in markdown files. Use proactively when auditing documentation, reviewing PRs that touch markdown files, or checking knowledge-copilot for broken links.

Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'link-validation' ~/.claude/skills/'link-validation' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
