property-graph plugins

Graph-engineering team — agents (graph-data-modeler, graph-query-engineer) for property-graph and RDF craft: when a graph beats relational, LPG vs RDF, labeled/typed modeling, supernodes, Cypher/ISO GQL/openCypher/Gremlin/SPARQL traversals, and GraphRAG construction (skill + command, not a dedicated agent). skills, commands, knowledge files (graph-vs-relational tree, LPG catalog, dated 2026 language/engine map, GraphRAG construction), best-practices, templates, scenarios, an advisory hook, a stdlib shape linter. Advisory only — snippets the user runs; no live graph runtime. Seams: when NOT a graph → database-engineering; vector/hybrid RAG → ai-rag-engineering; whether a memory graph beats BM25 → memory-engineering; GraphQL → graphql-engineering; Microsoft Graph API → microsoft-graph; Fabric Graph SKU → microsoft-fabric. Requires ravenclaude-core@>=0.7.0.

Rust MCP server that indexes ANY codebase into a LadybugDB property graph — source in 11 languages with full AST, plus docs/config/binaries as File nodes (.js→Imports, Markdown→References). Resolves imports and call chains, detects communities via Leiden, traces execution flows from entry points, and exposes 26 MCP tools to agents — index_codebase, query_graph, get_symbol, get_impact, get_context, semantic_diff, and more.
