使用说明 (SKILL.md)

dead-link-scanner

Find broken links in websites, markdown files, and HTML documents.

Quick Start

# Scan a website for broken links
python3 scripts/dead_link_scanner.py scan https://example.com

# Scan with depth limit (default: 1)
python3 scripts/dead_link_scanner.py scan https://example.com --depth 3

# Scan a local markdown file
python3 scripts/dead_link_scanner.py file README.md

# Scan multiple files
python3 scripts/dead_link_scanner.py file docs/*.md

# JSON output
python3 scripts/dead_link_scanner.py scan https://example.com --json

# Only show broken links
python3 scripts/dead_link_scanner.py scan https://example.com --broken-only

Commands

`scan`

Crawl a website and check all links on each page.

python3 scripts/dead_link_scanner.py scan \x3Curl> [options]

Options:

--depth \x3Cn> — Max crawl depth (default: 1, 0 = single page only)
--timeout \x3Cseconds> — Request timeout (default: 10)
--json — Output results as JSON
--broken-only — Only show broken links
--internal-only — Only check links within the same domain
--max-urls \x3Cn> — Max URLs to check (default: 200)
--delay \x3Cseconds> — Delay between requests (default: 0.2)

`file`

Scan local markdown or HTML files for broken links.

python3 scripts/dead_link_scanner.py file \x3Cpath>... [options]

Options:

--timeout \x3Cseconds> — Request timeout (default: 10)
--json — Output as JSON
--broken-only — Only show broken links

Output

Default text output:

✓ 200  https://example.com/about
✓ 200  https://example.com/blog
✗ 404  https://example.com/old-page  (found on: https://example.com)
✗ ERR  https://dead-domain.xyz  (found on: https://example.com) — ConnectionError

Summary line:

Checked 42 links: 39 OK, 3 broken

安全使用建议

This skill is coherent and implements a dead-link scanner in Python. Before installing or running it, be aware that: (1) it will make outbound HTTP(S) requests to every discovered URL (including internal/intranet addresses you point it at), which can trigger server logs or expose your agent's IP; (2) it reads only files you pass on the command line — avoid scanning sensitive files you don't intend to expose; (3) it does not appear to obey robots.txt and will crawl pages according to the provided depth/max-urls/delay settings, so use polite settings (delay, max-urls) when crawling third-party sites; and (4) the User-Agent includes an identifying URL, so contacted servers will see that string. If you need autonomous scanning across private networks or sensitive repos, review the script and enforce access controls and network restrictions first.

功能分析

Type: OpenClaw Skill Name: dead-link-scanner Version: 1.0.0 The 'dead-link-scanner' skill is a legitimate utility for identifying broken links in websites and local files. The Python script (scripts/dead_link_scanner.py) uses standard libraries (urllib, html.parser) to crawl URLs and parse files, incorporating safety features such as request delays, depth limits, and a maximum URL count to prevent abuse. No evidence of data exfiltration, malicious execution, or prompt injection was found.

能力评估

✓ Purpose & Capability

Name/description match the included Python implementation: the code crawls HTML pages, extracts links from HTML and Markdown, and checks links' HTTP status. It does not request unrelated capabilities (no cloud creds, no extra binaries).

✓ Instruction Scope

SKILL.md instructs the agent to run the included script to scan a URL or local files. The script only reads files explicitly passed to the 'file' command and performs network requests for discovered links; it does not attempt to read arbitrary system state or extra environment variables.

✓ Install Mechanism

There is no install spec; this is instruction+code only. The Python script is bundled with the skill and nothing is downloaded or executed from external installers.

✓ Credentials

The skill requires no environment variables, credentials, or config paths. The single notable hard-coded value is a USER_AGENT string (dead-link-scanner/1.0 (+https://clawhub.com)), which is benign but reveals an identifying User-Agent to servers it contacts.

✓ Persistence & Privilege

Skill does not request persistent or elevated privileges. always is false and it does not modify other skills or system configurations. It can be invoked autonomously by the agent (default), which is expected behavior for a skill.
