The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill mentions an instruction to install additional skills using npx skills add layerai/skills. This reference points to the vendor's own ecosystem and is a standard part of the platform's workflow for discovering and adding capabilities.
[COMMAND_EXECUTION]: The skill describes the use of specific tools: render_video_timeline, estimate_video_timeline_price, and get_generation_run. These are identified as first-party tools provided by the vendor ('layerai') for video composition tasks like sequencing, transitions, and overlays.
[DATA_EXPOSURE]: The skill uses file_id references for assets (video, image, audio) already present in the workspace. This is a secure method of referencing assets within the vendor's environment without exposing raw file paths or credentials.
[INDIRECT_PROMPT_INJECTION]: The skill handles user-provided text for overlays and captions. While this represents a data ingestion surface, the skill is focused on rendering these elements into a video file rather than re-interpreting them as instructions, and it includes a check step ('Watch the result end to end') for human/agent verification.
