The Agent Skills Directory

[COMMAND_EXECUTION]: The skill provides specific command-line instructions for the agent to execute agg, ffmpeg, ffprobe, and gifsicle within the terminal environment to perform media conversion and optimization.
[EXTERNAL_DOWNLOADS]: The skill references and directs the agent to documentation and repositories from trusted or well-known services, including GitHub (github.com/asciinema/agg), the official ffmpeg.org site, and lcdf.org for gifsicle. These references do not escalate the security verdict.
[INDIRECT_PROMPT_INJECTION]: The skill is designed to process external .cast files which represent untrusted input; however, the skill explicitly recommends using cast-redact to scan for secrets before rendering, which demonstrates a security-conscious design. The risk remains low as the output is typically visual media.
