安全使用建议
This skill appears to do what it says (ffmpeg-based keyframe extraction) but the metadata failed to declare that ffmpeg is a required binary and the SKILL.md references a LICENSE.txt that isn't in the package. Before installing, confirm you have ffmpeg on PATH and that you trust any local video files you process. If you maintain the skill, update the registry metadata to list ffmpeg under required binaries and include the LICENSE.txt or remove the reference. Because metadata and files disagree, treat this as a mild red flag rather than a showstopper.
功能分析
Type: OpenClaw Skill
Name: mario-coin-counting-ffmpeg
Version: 0.1.0
The skill bundle consists of standard documentation and command-line templates for using FFmpeg to extract keyframes from video files. The instructions in SKILL.md are well-documented, align perfectly with the stated purpose, and contain no malicious commands, network calls, or prompt-injection attempts.
能力评估
Purpose & Capability
The SKILL.md clearly describes extracting keyframes with FFmpeg and provides appropriate commands. However, the registry metadata lists no required binaries while the instructions explicitly require 'ffmpeg' to be installed and on PATH. That mismatch is unexpected and should be corrected (requires.binaries should list ffmpeg).
Instruction Scope
The runtime instructions only describe running local ffmpeg commands on an input video and writing output image files. They do not ask the agent to read unrelated files, access secrets, or contact external endpoints.
Install Mechanism
This is an instruction-only skill with no install spec or code to download or execute — lowest install risk.
Credentials
No environment variables, credentials, or config paths are requested. The skill's functionality needs only local ffmpeg and file access, which is proportional to its purpose.
Persistence & Privilege
The skill is not always-enabled and has normal autonomous invocation settings. It does not request elevated or persistent privileges.
