Usage
free-tool [options]

free-tool -h -t
安全使用建议
This skill appears to do what it says: a tiny Python script that reads /proc/meminfo and prints memory fields. It requests no secrets and has no installer, so risk is low. Two caveats: (1) the README/ SKILL.md advertises CLI options and an executable name that are not implemented — expect to run the script directly (python3 scripts/free.py) or provide your own wrapper if you need those options; (2) because it reads /proc, it reveals system memory info (non-sensitive in most contexts) — consider whether exposing that to the agent is acceptable in your environment. If you want the documented CLI behavior, ask the author for a proper wrapper or update before installing.
功能分析
Type: OpenClaw Skill
Name: free-tool
Version: 1.0.0
The skill provides a simple utility to report system memory usage by reading /proc/meminfo in scripts/free.py. Although SKILL.md describes command-line options that are not actually implemented in the Python script, the code is functional for its basic purpose and contains no malicious logic, network activity, or security vulnerabilities.
能力评估
Purpose & Capability
Name/description (report system memory usage) match the included script, which reads /proc/meminfo and prints relevant memory lines. No unrelated credentials, binaries, or install steps are requested.
Instruction Scope
SKILL.md documents a CLI with options (-h, -m, -g, -t) and examples, but the included scripts/free.py does not parse arguments or implement those options. Also SKILL.md implies an executable named `free-tool` though no install mechanism or wrapper is provided. This is a usability/incoherence issue rather than a security risk.
Install Mechanism
No install spec — instruction-only plus a tiny script. Nothing is downloaded or written to disk beyond the provided file, so install risk is minimal.
Credentials
No environment variables, credentials, or external config paths are requested. The script reads /proc/meminfo, which is appropriate and proportionate for reporting memory usage.
Persistence & Privilege
Skill is not always-on and does not request elevated persistence or modify other skills or system-wide settings. It can be invoked by the agent but has no broad privileges.
