链接与资讯真实性核验工具，检查链接是否可访问、交叉验证资讯真实性。

The skill's documentation promises cross-source fact-checking but the code only checks whether a URL responds and extracts its <title>. Before installing or using it for verification: 1) don't trust it to perform cross-checks — ask the author or inspect/modify the code to actually call web_search and aggregate sources; 2) be aware the skill will fetch any URL you provide (so don't submit private links or links containing secrets); 3) the fetch timeout and HEAD behavior may not behave as expected in some runtimes — test with known URLs; 4) if you need real fact-checking, request/require an implementation that performs authenticated searches (if needed), documents which search endpoints are used, and shows how results are aggregated/weighted. If the mismatch was accidental, ask the publisher to update SKILL.md or the code to align functionality and provide provenance for its searches.

Type: OpenClaw Skill Name: link-fact-checker Version: 1.0.0 The skill provides legitimate functionality for checking URL accessibility and retrieving page titles as described in SKILL.md. The implementation in index.js uses standard fetch requests to perform HEAD and GET operations on user-provided URLs without any evidence of data exfiltration, unauthorized access, or malicious intent.
