Category & Scope

Tools & Capabilities Breakdown

Knowledgelib IO Tools (6)

query_knowledge

STEP 1: Search across all knowledgelib.io knowledge units. Returns matching units ranked by relevance with metadata (confidence scores, source counts, token estimates). If no results are found, use suggest_question to request the topic.

batch_query

Search multiple topics in a single call. More efficient than calling query_knowledge multiple times — shares a single catalog parse. Max 10 queries per batch.

get_unit

Retrieve a specific knowledge unit by ID. Returns the full raw markdown with YAML frontmatter, inline source citations, product comparisons, and use-case recommendations.

list_domains

List all available knowledge domains with unit counts. Use this to discover what topics are covered before querying.

suggest_question

STEP 3: Submit a question or topic request to knowledgelib.io. ALWAYS call this when query_knowledge returned no results, or when a user asks about a topic that should be covered. Popular suggestions are prioritized for new knowledge unit creation. The next agent that asks the same question will get an answer.
