/install windows-screenshot
功能描述
Pure PowerShell GDI+ screenshot tool for Windows. No external dependencies, captures to PNG with automatic scaling.
安全使用建议
This skill appears to do exactly what it claims: capture the primary Windows screen and save a PNG locally. Before running it: (1) review the included screenshot.txt yourself (it's short and plain PowerShell); (2) be aware screenshots can contain sensitive data—don't run it in contexts with secrets you wouldn't want saved; (3) the script creates/uses $USERPROFILE\.openclaw\media by default (or a folder you set via OPENCLAW_MEDIA_DIR); (4) the Telegram example in the docs is optional and would only transmit images if you explicitly configure and run that separately with your bot token. If any of those behaviors are unacceptable, do not run the script or edit the output path first.
功能分析
Type: OpenClaw Skill
Name: windows-screenshot
Version: 1.0.3
The skill provides a legitimate PowerShell script (screenshot.txt) to capture the primary screen using standard .NET GDI+ libraries and save it locally. The code is transparent, lacks network activity, obfuscation, or suspicious instructions, and functions exactly as described in the documentation (SKILL.md).
能力评估
Purpose & Capability
Name/description match the contents: the included PowerShell script captures the primary Windows screen using GDI+ and saves a PNG. No unrelated binaries, credentials, or installs are requested.
Instruction Scope
Runtime instructions simply run the provided PowerShell script which writes a PNG to $USERPROFILE\.openclaw\media (or OPENCLAW_MEDIA_DIR if set) and prints a MEDIA: path. The doc includes an optional example showing how a user could send the image via Telegram, but the script itself makes no network calls and does not read other system state. Users should note that screenshots may contain sensitive information.
Install Mechanism
No install spec and no code is downloaded or executed from remote hosts. This is an instruction-only skill with the PowerShell script included as screenshot.txt.
Credentials
The script optionally reads a single environment variable OPENCLAW_MEDIA_DIR to choose the output folder. No credentials or unrelated env vars are required. The Telegram example references TELEGRAM_BOT_TOKEN but that is not required by the script and is only part of an external manual workflow.
Persistence & Privilege
always is false and the skill does not request persistent privileges or modify other skills or system-wide settings; it only creates (if needed) and writes files in a per-user media directory.
