Full Analysis
  • [INDIRECT_PROMPT_INJECTION]: The skill implements a harness for retrieval-augmented generation (RAG) that ingests data from search backends to answer queries.
  • Ingestion points: Untrusted data enters the agent context via the search function implemented in scripts/search_loop.py and scripts/keyword_search.py.
  • Boundary markers: The skill uses explicit system instructions to guide the model, directing it to ground responses in retrieved evidence and acknowledge gaps in information.
  • Capability inventory: The skill is designed to call external search functions and communicate with the Mixedbread API for model completions.
  • Sanitization: The harness includes logic to clip, prune, and deduplicate evidence to manage context budget, though it does not perform semantic sanitization of retrieved content.
  • [EXTERNAL_DOWNLOADS]: The documentation and example scripts reference the openai Python library. This is a standard and trusted package used for API interaction.
  • [SAFE]: The skill uses environment variables for sensitive data (e.g., MXBAI_API_KEY) and directs all network traffic to official vendor endpoints (api.mixedbread.com). No malicious patterns such as obfuscation or persistence were detected.
