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~/.zshrcand a file namedreference_gemini_api_keys.mdto 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.,
concat) inSKILL.mdandscripts/render_master.py. - [COMMAND_EXECUTION]: The skill includes Python scripts that execute shell commands via the
subprocessmodule, which are used for video and audio processing. scripts/render_master.pyandscripts/scrub_beeps.pyboth utilizesubprocess.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.
