功能描述
Scan websites and files for broken links with HTTP status details. Use when auditing links, finding broken URLs, validating references.
使用说明 (SKILL.md)
DeadLink — Dead Link Checker
Check URLs for broken links. Scan individual URLs, files containing links, or crawl websites. Generates reports with HTTP status codes.
Commands
| Command | Description |
|---|---|
check \x3Curl> |
Check a single URL — shows HTTP status, redirect target if applicable |
scan \x3Cfile> |
Extract and check all URLs found in a text file |
site \x3Curl> [depth] |
Crawl a webpage, extract all href/src links, and check each one |
report \x3Cfile> |
Generate a timestamped report file from all URLs in a text file |
Examples
# Check a single URL
deadlink check https://example.com/page
# → 200 OK
# Scan a markdown file for broken links
deadlink scan README.md
# → Extracts all http/https URLs and checks each one
# Crawl a website
deadlink site https://example.com 1
# → Fetches the page, extracts all links, checks each
# Generate a report file
deadlink report bookmarks.html
# → Creates deadlink-report-20240101-120000.txt
Status Codes
- 2xx — OK (alive)
- 3xx — Redirect (alive, shows final URL)
- 4xx — Client error (dead — 404 Not Found, 403 Forbidden, etc.)
- 5xx — Server error (dead)
- 000 — Connection failed (DNS error, timeout, unreachable)
Requirements
curl— must be installed and in PATH- Network access to check URLs
Notes
- Timeout: 10 seconds per URL (5s connect timeout)
- URLs are extracted using regex pattern matching for
http://andhttps://links - The
sitecommand does basic HTML link extraction (href and src attributes) - Reports are saved as plain text files in the current directory
安全使用建议
This skill appears to do exactly what it says: check URLs and produce local reports. Before installing, ensure curl is available on the host (SKILL.md requires it despite registry metadata not listing binaries). Be aware that running scans or site crawls will generate outgoing HTTP(S) requests to every target URL (respect robots/terms of service and avoid aggressive scans against sites you don't own). The User-Agent string includes bytesagain.com but that is only an identifier — the script does not contact that domain. If you plan to scan large sites, consider rate-limiting and the legal/ethical implications; run it in an environment where outgoing network traffic is acceptable.
功能分析
Type: OpenClaw Skill
Name: deadlink
Version: 3.0.0
The DeadLink skill is a legitimate utility for auditing URLs and identifying broken links. The bash script (scripts/script.sh) uses curl to verify HTTP status codes and grep/sed for basic URL extraction from files and HTML content, which aligns perfectly with its stated purpose in SKILL.md. There are no signs of data exfiltration, persistence mechanisms, or malicious prompt injection.
能力评估
Purpose & Capability
The name/description, SKILL.md, and the included bash script are consistent: they implement URL checking, file scanning, crawling, and report generation. Minor metadata mismatch: the registry metadata lists no required binaries, but SKILL.md and the script require curl (and use common shell tools like grep/sed/sort). Asking for curl is reasonable for this purpose.
Instruction Scope
Runtime instructions and the script only fetch URLs (using curl), extract links from provided files or fetched pages, and write plain-text reports to the current directory. The script follows redirects, applies a 10s timeout, and uses a recognizable User-Agent string; it does not read unrelated files, environment variables, or send data to third-party endpoints beyond the URLs being checked.
Install Mechanism
No install spec — instruction-only plus an included bash script. No downloads or package installs are performed by the skill itself, so there is no high-risk install mechanism.
Credentials
The skill declares no environment variables or credentials and the code does not access secrets or config paths. Network access is required and justified by the stated functionality.
Persistence & Privilege
The skill is not marked always:true and does not attempt to modify other skills or system-wide settings. It writes report files only to the current working directory, which is proportional to its purpose.
