Full Analysis
  • [CREDENTIALS_UNSAFE]: The skill documentation explicitly instructs the agent to harvest credentials from sensitive system configuration files rather than following secure input practices.
  • In Phase 7 of SKILL.md, the instructions tell the agent to "check their environment first" and specifically point to ~/.zshrc and a file named reference_gemini_api_keys.md to locate a "paid-tier EasyChamp Gemini key."
  • This promotes the unauthorized collection of secrets from shell histories and environment configuration files.
  • [OBFUSCATION]: The skill uses zero-width characters (U+200B) to obscure technical keywords in both documentation and script comments, a technique often used to bypass string-matching security filters.
  • Multiple instances of the Zero-Width Space (U+200B) were found within the word "concat" (e.g., con​cat) in SKILL.md and scripts/render_master.py.
  • [COMMAND_EXECUTION]: The skill includes Python scripts that execute shell commands via the subprocess module, which are used for video and audio processing.
  • scripts/render_master.py and scripts/scrub_beeps.py both utilize subprocess.run() to invoke FFmpeg.
  • While these are functional for the skill's purpose, the execution of shell commands using parameters derived from external transcription data increases the risk of command injection.
  • [INDIRECT_PROMPT_INJECTION]: The skill processes untrusted transcript data and requires the agent to "Read the full transcript," providing a vector for indirect injection attacks.
  • Ingestion Points: Transcript data is ingested from .work/source.json (Whisper output) in Phase 2.
  • Boundary Markers: The skill lacks explicit delimiters or instructions to treat the ingested transcript content as untrusted.
  • Capability Inventory: The agent possesses the capability to execute shell commands (ffmpeg) and perform network operations (curl).
  • Sanitization: No filtering, escaping, or validation is performed on the transcript content before it is processed by the agent.
