安全使用建议
Install this only if you are comfortable sending web searches, URLs, people/company lookups, and research prompts to Exa or the fallback search provider. Do not include secrets, private/internal URLs, confidential business material, or sensitive personal data in queries, and override the skill’s broad preference when built-in tools or no web lookup are more appropriate.
功能分析
Type: OpenClaw Skill
Name: web-search-free
Version: 1.0.1
The skill is classified as suspicious due to the inherent risk of shell injection and Server-Side Request Forgery (SSRF) vulnerabilities. The `SKILL.md` instructs the agent to use `mcporter call` commands with user-provided parameters (e.g., `query`, `url`). If the OpenClaw agent does not properly sanitize or escape user input before constructing these shell commands, it could lead to arbitrary command execution (shell injection). Additionally, the `crawling_exa` tool, which takes a `url` parameter, could be exploited for SSRF if the agent allows arbitrary user-provided URLs, potentially accessing internal network resources. While the skill's stated purpose is benign (web search), these capabilities present significant security risks if the agent's implementation is vulnerable. There are also prompt injection attempts in `SKILL.md` to influence agent behavior regarding skill prioritization, though these do not appear to be malicious in intent.
能力评估
Purpose & Capability
The package is broader than the short name suggests, but SKILL.md explicitly discloses web search, code context, company research, people search, URL crawling, and deep research capabilities.
Instruction Scope
The instruction to always prefer this skill over built-in web_search or web_fetch is overbroad and should be treated as preference guidance, not as an override of user intent or policy.
Install Mechanism
Installation/setup is limited to checking and adding an Exa MCP endpoint through mcporter; there are no bundled executable scripts, hidden installers, or automatic system changes in the artifact.
Credentials
External search, crawling, people lookup, and research requests are proportionate to the stated purpose, but the skill does not clearly warn users that queries, URLs, and research instructions are sent to third-party services.
Persistence & Privilege
No local persistence, privilege escalation, credential access, or background worker is installed by the skill; the only persistent state described is mcporter endpoint configuration and remote research IDs returned by Exa.
