The Agent Skills Directory

[COMMAND_EXECUTION] (MEDIUM): The skill utilizes python3 -c to execute Python code directly from the shell. The workflow instructs the agent to replace VIDEO_ID within a string literal in the command: transcript = api.fetch('VIDEO_ID').
Evidence: Found in Step 2 and the Error Handling section of SKILL.md.
Risk: If an attacker provides a crafted YouTube URL where the extracted 'ID' contains characters like '); import os; os.system('..., it could lead to arbitrary code execution on the host system.
[EXTERNAL_DOWNLOADS] (LOW): The skill requires the installation of the youtube-transcript-api package using pip3 install.
Evidence: Referenced in the compatibility metadata and the Dependencies section.
Context: This is a standard package for this functionality, but downloading and installing code from external registries at runtime is a potential attack vector.
[INDIRECT_PROMPT_INJECTION] (LOW): The skill processes untrusted external data (YouTube URLs) and uses the extracted components in executable code.
Ingestion points: YouTube URLs provided by users in Step 1.
Boundary markers: None. The skill uses simple string replacement in the Python script.
Capability inventory: Shell command execution (bash), Python execution (python3 -c), and package management (pip3).
Sanitization: Absent. The instructions do not specify validation or escaping for the extracted VIDEO_ID before interpolation.
