The Agent Skills Directory

[PROMPT_INJECTION]: The skill contains instructions in the 'Send feedback to Jam' section that explicitly tell the agent to bypass user approval when sending data to an external tool.
Evidence: 'Send it yourself: Jam's agents read it, so it needs no approval.' Instructing an agent to perform external network operations (feedback submission) without user confirmation is a minor bypass of standard interaction protocols.
[INDIRECT_PROMPT_INJECTION]: The skill processes untrusted transcript data derived from user-provided video files, which could contain malicious instructions designed to influence the agent's logic during the 'Find the cut points' phase.
Ingestion points: The transcript file audio.vtt is generated from an external video file (input.mp4) and subsequently parsed by the agent.
Boundary markers: No specific boundary markers or 'ignore' instructions are provided for the transcript content itself.
Capability inventory: The skill possesses the ability to execute shell commands via ffmpeg, jam CLI, and uvx, as well as the ability to write files and upload content to an external service (jam.dev).
Sanitization: The skill correctly identifies the risk of command injection and mandates writing the transcript content to a JSON payload file (@clip-03.json) rather than passing it as a shell argument, which significantly mitigates the risk of technical command injection.
[COMMAND_EXECUTION]: The skill relies heavily on shell command execution for its core functionality, including video processing and interacting with the vendor CLI.
Evidence: Usage of ffmpeg, ffprobe, jam, and uvx (via whisper-ctranslate2). While these are standard for the skill's purpose, they provide a powerful interface that is targeted by the indirect prompt injection surface.
