Validates Markdown files for broken local links.
Security Analysis
high confidenceThe skill's code and runtime instructions match its stated purpose (scanning Markdown files for broken local links); it requires no credentials, no installs, and does not perform unexpected network access.
Name/description match the included code: index.js recursively scans directories for .md files, parses Markdown links, skips http/https and in-file anchors, resolves relative paths, and reports missing targets. No unrelated binaries or credentials are requested.
SKILL.md directs running the bundled Node script against a target path (default '.'), which will read all Markdown files under that path (excluding node_modules and .git). This is consistent with purpose, but be aware it will read any .md files under the target directory (so don't point it at a directory containing sensitive markdown if you are concerned about disclosure of link metadata).
There is no install spec — this is an instruction+code skill. The provided code is plain JS (no external downloads or archive extraction). Nothing is written to disk by the skill itself other than normal output.
The skill declares no environment variables or credentials and the code does not attempt to read env vars or external config. It also explicitly avoids network calls by skipping http/https links.
The skill does not request persistent presence (always is false) and does not modify other skills or global agent config. It operates solely on the filesystem paths the user targets when invoked.
Guidance
This skill appears to do exactly what it says: run the bundled Node script against the directory or file you want checked. Before running: (1) review the small index.js file (already provided) if you want to confirm behavior; (2) avoid pointing the skill at a home or system directory if you have sensitive Markdown files you don't want inspected; (3) note that the included test script creates and deletes two files only when you run tests (it does not run automatically on install); and (4) because the skill skips http/https links it will not perform network calls. If you want extra assurance, run the script locally in a controlled repo first.
