安全使用建议
This skill appears to do what it says (web scraping and export) but has a few small mismatches you should verify before installing. Ask the author for source code or a homepage so you can confirm what the helper tools (web_fetch, read, write) actually do. Specifically: 1) Confirm why config.json lists an 'exec' capability and whether the skill will run shell commands. 2) Confirm the scope of the 'read' tool (which directories/files it can access). 3) If you proceed, run it in a sandboxed environment and do not supply any credentials. 4) Ensure its crawling respects robots.txt and target terms of service. If the author cannot provide a clear explanation or source, treat the skill as higher risk and avoid granting broad read/exec access.
功能分析
Type: OpenClaw Skill
Name: web-data-extractor
Version: 1.0.0
The skill bundle requests the 'exec' capability in config.json, which allows for arbitrary command execution, yet this high-risk permission is not listed in the SKILL.md requirements nor is it justified by the stated purpose of web scraping. While the provided documentation (SKILL.md) describes benign data extraction tasks, the discrepancy in requested permissions represents a potential security risk or over-privileging without a clear functional necessity.
能力评估
Purpose & Capability
The name/description (web scraping and export) align with requiring a fetch tool and write capability to save CSV/JSON. However config.json lists an additional 'exec' capability that is not declared in the SKILL.md's required bins and is not explained — running arbitrary commands via exec is more powerful than the described feature set and creates a mismatch.
Instruction Scope
SKILL.md uses high-level helper calls (web_fetch, extractData, exportToCSV) and expects 'read'/'write' tooling. The doc is vague about what files the 'read' tool can access or whether the skill will read arbitrary user files or agent state. The examples do not define these helpers (this is an instruction-only skill), giving the agent broad discretion to call local read/write/exec primitives in ways that aren't explicitly limited by the instructions.
Install Mechanism
No install spec and no code files — instruction-only — so nothing is being downloaded or written to disk by the skill itself. This is the lowest install risk.
Credentials
The skill requests no environment variables or external credentials (good). But it does require 'read' and 'write' binaries which, depending on the platform, can allow access to any file the agent can read/write. Exporting data justifies write access, but read access is not clearly justified beyond potentially reading input URL lists; that could be overbroad.
Persistence & Privilege
always is false and there's no indication the skill requests persistent global privileges or modifies other skills. Autonomous invocation is allowed (platform default) but not combined with other strong red flags here.
