Description
Validates Markdown files for broken local links.
Usage 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.
Capability Analysis
Type: OpenClaw Skill
Name: markdown-validator
Version: 1.0.0
The skill 'markdown-validator' is designed to validate Markdown files for broken local links. The `index.js` script uses standard Node.js `fs` and `path` modules to read files and directories, parse Markdown links, and check their existence on the local file system. It explicitly avoids network calls for external links. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, obfuscation, or prompt injection attempts in `SKILL.md`. All file operations are directly related to the stated purpose of validating Markdown links, and there are no indicators of intentional harmful behavior.
Capability Assessment
Purpose & Capability
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.
Instruction Scope
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).
Install Mechanism
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.
Credentials
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.
Persistence & Privilege
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.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install markdown-validator - After installation, invoke the skill by name or use
/markdown-validator - Provide required inputs per the skill's parameter spec and get structured output
