The Agent Skills Directory

[COMMAND_EXECUTION]: The skill executes multiple shell commands including curl for network requests, jq for JSON processing, and image processing tools like magick or sips to handle book cover creation and resizing.
[EXTERNAL_DOWNLOADS]: The skill downloads content from user-provided URLs specified in the REF_IMAGE parameter in SKILL.md to use as reference material for image generation.
[INDIRECT_PROMPT_INJECTION]:
- Ingestion points: The skill accepts user-supplied book titles, author names, and stylistic preferences in SKILL.md.
- Boundary markers: Absent; user input is interpolated directly into English prompt templates.
- Capability inventory: The skill has network access (curl), file system access (mkdir, cp), and image processing capabilities (magick, sips) across its scripts in SKILL.md.
- Sanitization: The skill uses jq to properly escape user input when constructing API payloads, mitigating traditional command injection, though the generated prompt remains an injection surface for the image model.
