Full Analysis
  • [COMMAND_EXECUTION]: The PostgreSQL hybrid search template in resources/implementation-playbook.md dynamically constructs SQL WHERE clauses using f-strings for dictionary keys in the filter_metadata parameter. This pattern allows for potential SQL injection if the keys are sourced from untrusted user input.
  • [EXTERNAL_DOWNLOADS]: The PostgresHybridSearch.search_with_rerank method in resources/implementation-playbook.md fetches a pre-trained model from Hugging Face's public repository (cross-encoder/ms-marco-MiniLM-L-6-v2) for reranking search results.
  • [PROMPT_INJECTION]: The skill architecture is designed to process untrusted data (search queries and document content) within a RAG pipeline, presenting a surface for indirect prompt injection.
  • Ingestion points: User-provided search queries and document content retrieved from databases or Elasticsearch as seen in resources/implementation-playbook.md.
  • Boundary markers: None identified in the provided implementation templates.
  • Capability inventory: Database querying via asyncpg, search operations via elasticsearch, and local model inference via sentence_transformers.
  • Sanitization: No input sanitization or instruction filtering is implemented in the provided code templates.
