One of 14 test cases the skill fixed. Same model, same prompt, with and without the skill.
Which tool call retrieves high-level summary metrics, document status counts, and metadata for a specific collection named HR_POLICIES?
| Checked | Without skill | With skill |
|---|---|---|
| Calls manage_rag_content with action get_collection and name set to HR_POLICIES. | Missed | Passed |
The instructions your model reads when the skill loads.
Two tools cover the entire RAG surface:
manage_rag_content — collections, document ingestion, status polling, deletionrag_query — semantic search, optional LLM synthesisDocuments are ingested asynchronously: text or files become embeddings stored in pgvector, and queries do a similarity search at runtime.
Collection Documents Chunks
────────── ────────── ──────
"product-faq" ──────────────► doc_1 (PDF) ───────────► chunk 1, 2, 3...
doc_2 (text) ──────────► chunk 4, 5...
doc_3 (markdown) ──────► chunk 6...
A collection holds documents; a document is split into chunks and embedded; rag_query searches by cosine similarity across chunks within a collection.
chunk_size and chunk_overlap are set once at collection creation and immutable — to change them, delete and recreate the collection.
