# Semantica

This Skill helps Claude apply Semantica knowledge graph capabilities to context graph analysis, decision intelligence, explainability, semantic extraction, graph analytics, reasoning, provenance, ontology, policy, ingestion, deduplication, and export.

## When to use this Skill

- The user asks about knowledge graphs, entities, relations, triplets, or semantic extraction.
- A task requires context graph analysis, graph topology, centrality, communities, paths, or embeddings.
- The request involves decision intelligence, causal influence, decision graphs, or outcome analysis.
- The user asks for explainability, decision rationale, or transparency for graph results.
- The request involves reasoning: deductive, abductive, SPARQL, Datalog, or Rete rules.
- The user needs provenance, audit history, lineage tracking, or change tracing.
- The request is about ontology modeling, schema validation, or policy enforcement.
- Data must be ingested from files, databases, APIs, repositories, or MCP servers.
- There is a need to deduplicate entities, normalize graph data, or merge duplicate graph objects.
- The user wants to export graphs to JSON, RDF, Parquet, CSV, GraphML, or similar.
