Usage Guidance
This skill appears to do exactly what it says: make HTTP(S) requests, time them, hash responses, and optionally check for text. Before installing or running it, review the included main.py (already provided) if you will point it at sensitive internal URLs; the script will perform outbound requests to whatever URLs you supply. It does not exfiltrate data to other endpoints or read local secrets, but run it in a restricted environment if you have strict network/data policies. If you need authenticated checks, note the script does not handle credentials or cookies by default.
Capability Analysis
Type: OpenClaw Skill
Name: skill-4
Version: 1.0.0
The skill bundle provides a lightweight website uptime monitor. The `SKILL.md` accurately describes the tool's functionality and usage, without any evidence of prompt injection attempts against the AI agent. The `main.py` script uses only Python's standard library (`urllib`, `hashlib`, etc.) to perform its stated purpose of checking URLs, measuring response times, and detecting content changes. There is no indication of malicious behavior such as data exfiltration, unauthorized command execution, persistence mechanisms, or obfuscation. Network requests are limited to user-provided URLs, which is inherent to its function.
Capability Assessment
Purpose & Capability
Name/description (uptime, response time, hashing, text checks) match the included code and CLI options. The tool uses only the Python standard library and requires no external services or credentials, which is proportionate to its stated purpose.
Instruction Scope
SKILL.md tells the agent to run the bundled Python script with URL arguments and flags. The runtime instructions and code only perform HTTP(S) requests to the target URLs, measure timing, compute hashes, and optionally check text — they do not read unrelated files, environment variables, or send data to third-party endpoints beyond the requested target URLs.
Install Mechanism
No install spec is provided and the skill is instruction-only with a single Python script that relies on the standard library. Nothing is downloaded or written to disk by an installer.
Credentials
The skill declares no required environment variables, credentials, or config paths. The code likewise does not access environment variables or secrets. This is proportionate to a basic website monitoring tool.
Persistence & Privilege
The skill does not request always:true and does not attempt to modify other skills or system settings. It can be invoked by the agent (disable-model-invocation is false), which is the platform default and appropriate for a user-invokable monitoring skill.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install skill-4 - After installation, invoke the skill by name or use
/skill-4 - Provide required inputs per the skill's parameter spec and get structured output
