安全使用建议
Review this skill before installing, especially on Windows. Its core screenshot function is understandable, but avoid untrusted output filenames and be aware that screenshots can capture sensitive information visible on your screen.
功能分析
Type: OpenClaw Skill
Name: dinghaibin-screenshot-tool
Version: 1.0.0
The skill provides legitimate screenshot and recording functionality but contains a command injection vulnerability in the Windows-specific logic within `scripts/screenshot.py`. The `--output` parameter is interpolated directly into a PowerShell script string without sanitization, potentially allowing arbitrary code execution via a crafted filename. While the tool's behavior aligns with its stated purpose and shows no evidence of intentional malice or exfiltration, this security flaw warrants a suspicious classification.
能力评估
Purpose & Capability
Capturing screenshots and recordings is the stated purpose and is implemented directly, but users should remember that screen captures can include private visible information.
Instruction Scope
The SKILL.md examples are user-directed CLI commands and do not instruct the agent to run automatically or ignore user intent.
Install Mechanism
There is no install spec and no required binaries declared, while the script relies on local platform screenshot tools. This is disclosed in the code and appears purpose-aligned, but users may need to verify local dependencies.
Credentials
On Windows, the script invokes PowerShell with a dynamically formatted script that embeds the user-controlled output path without escaping.
Persistence & Privilege
No credentials, network access, background persistence, or long-running autonomous behavior are shown; the tool writes screenshot files to the requested output path.
