Ontology Building
Build a structured ontology for a research domain. Extracts concepts from sources, types their relationships, constructs taxonomies, validates consistency, and iteratively refines until the ontology is coherent and complete.

Strategy Sequence (Reference, Not Prescription)
- domain-scoping — define boundaries, identify seed concepts, classify topic size
- concept-extraction — mine sources for concepts, create pages, resolve aliases
- relation-typing — identify and type relationships between concepts
- taxonomy-validation — check hierarchy consistency, detect gaps and conflicts
- ontology-refinement — merge near-duplicates, fill gaps, update confidence scores
CC may reorder, skip, or repeat strategies based on the domain's needs.
MCP Tools Used
vault_search — find existing concepts, detect duplicatesvault_add_edge — create typed relationshipsvault_query_graph — explore concept neighborhoodsvault_graph_stats — assess ontology coverage and connectivityvault_lint — validate structural integrityvault_index — maintain search index
Context-Management
- Call `context-init` at campaign start
- Call `context-checkpoint` after each strategy completes
- Call `knowledge-compilation` (wiki-vault tactic) after each strategy
Guiding Principles
- Breadth before depth. Map the concept landscape broadly before drilling into any sub-area.
- Edges over pages. A concept without relationships is useless. Prioritize connecting over creating.
- Aliases are enemies. The same concept with different names fragments the ontology. Resolve aggressively.
- Confidence is honest. Mark uncertain classifications explicitly. Low confidence is better than false certainty.
- The ontology is never finished. Each research session may reveal new concepts or invalidate old ones.
