CTX Link Check — Documentation Link Auditor

What it does

CTX Link Check scans a repository's documentation (markdown files) to find broken internal links, missing images, and external URLs that return errors or time out. It runs a two-pass internal/external check plus image verification and outputs a human-readable report with locations and suggested fixes.

When to use it

Use before documentation releases, after renaming or moving pages, during audits (/_ctx-audit), or when users report 404s. It's intended for projects with docs/, doc/, documentation/, or similar directories, and falls back to scanning root .md files if needed.

What's included

• Scripts: none bundled, but the skill explicitly describes commands and network checks (HEAD then GET fallbacks) and rules for skipping localhost/example domains.
• References: none listed, but quality checklist and integrations with audit flows are provided.
• Instructions: scope discovery rules, two-pass execution (internal file resolution + external HTTP checks), image verification, output format, and remediation suggestions (rename suggestions, removal, or pointing to alternatives).

Compatible agents

Best for agents that can read repository files and perform HTTP requests (bash/curl-capable assistants, CI bots, or documentation tooling agents).
