使用说明 (SKILL.md)

Broken Link Checker

Verify external URLs for availability. Useful for checking documentation links or external references.

Usage

node skills/broken-link-checker/index.js \x3Curl1> [url2...]

Output

JSON array of results:

[
  {
    "url": "https://example.com",
    "valid": true,
    "status": 200
  },
  {
    "url": "https://example.com/broken",
    "valid": false,
    "status": 404
  }
]

安全使用建议

This skill appears to be what it claims: a small Node script that issues HTTP HEAD requests to the URLs you provide, returns a JSON array of results, and exits non‑zero if any URL is considered broken. Before installing: ensure you have Node available; be aware HEAD requests can be rejected by some servers (causing false negatives) and the script will exit with code 1 on any invalid link which may affect CI pipelines. Also note the SKILL.md usage path may need to be adjusted to where index.js is located, and the test script contacts google.com — run tests in an environment where outbound HTTP(S) is allowed and acceptable.

功能分析

Type: OpenClaw Skill Name: broken-link-checker Version: 1.0.0 The 'broken-link-checker' skill is benign. The `index.js` code correctly implements its stated purpose of checking URL availability using standard Node.js `http`/`https` modules with `HEAD` requests. It filters command-line arguments to ensure they start with 'http', and there are no signs of data exfiltration, malicious execution, persistence mechanisms, or prompt injection attempts in `SKILL.md`. All observed behavior aligns with a safe and functional link checker.

能力评估

✓ Purpose & Capability

Name/description match the included code: index.js performs HTTP(S) HEAD requests and returns JSON results. There are no unrelated env vars, binaries, or services requested.

ℹ Instruction Scope

Runtime instructions are limited to running the included Node script. Minor inconsistencies: SKILL.md shows usage 'node skills/broken-link-checker/index.js' while the bundle places index.js at the package root (user/runtime may need to adjust the path). The implementation uses HEAD requests (some servers reject HEAD with 405), and the script exits with code 1 if any URL is invalid — behavior worth knowing but not malicious.

✓ Install Mechanism

No install spec, no external downloads, and package.json has no dependencies. Nothing is written to disk beyond the included files.

✓ Credentials

No environment variables, credentials, or config paths are requested. The code does not access process.env or other system secrets.

✓ Persistence & Privilege

Skill does not request persistent/always-on presence and does not modify other skills or system configuration.
