SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? When answering questions about a specific repository, you often need grounded context instead of guessing. This Skill retrieves the most relevant knowledge base snippets from a specified CNB repository, along with their sources, so answers are backed by actual repository knowledge. ## Core Features & Use Cases - Knowledge Base Retrieval: Query a specified repository's knowledge base with natural language questions or keywords. - Source Attribution: Returns relevant text fragments together with their origins for traceable answers. - Configurable Result Count: Control how many snippets are returned via the top-k parameter. - Use Case: A user asks how a feature works in the cnb/feedback repository. Run the query command with the repo path and question to get the top matching knowledge snippets, then answer the user based on the retrieved content. ## Quick Start Ask the assistant to query the knowledge base of a specific CNB repository, for example: search the cnb/feedback repository knowledge base for how issue notifications work and return the top 5 snippets.
