The Agent Skills Directory

[COMMAND_EXECUTION]: The skill makes extensive use of system CLI tools including exiftool, cwebp, convert (ImageMagick), and ffmpeg to read/write image metadata and perform format conversions.
[PRIVILEGE_ESCALATION]: The documentation instructs the user to execute sudo apt install commands to install the necessary image processing libraries on their system.
[INDIRECT_PROMPT_INJECTION]: The skill is designed to ingest and process data from external URLs and image files, which presents a surface for indirect prompt injection.
Ingestion points: External web pages via the [url] argument and existing image file metadata during optimization routines.
Boundary markers: None identified in the skill instructions to separate untrusted data from processing logic.
Capability inventory: Subprocess calls to exiftool, cwebp, and ImageMagick are used to manipulate files based on extracted metadata.
Sanitization: No explicit sanitization or validation of the extracted alt text or metadata is documented before being passed to shell commands.
