knowledge_graph_skill SKILL.md skillA
knowledge_graph_skill from npc-worldwide/npcpy is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add npc-worldwide/npcpy/knowledge_graph_skill@git:20260620.da69752Pins git:20260620.da69752 in mdr.lock. Pin the fingerprint instead.

"Skill for searching and evolving the SQLite-backed Knowledge Graph.\.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# knowledge_graph_skill
Skill for searching and evolving the SQLite-backed Knowledge Graph. Use this when you need structured fact/concept/link search across one or more teams, NPCs, or directory scopes.
The Knowledge Graph (KG) is stored in the application's database (not YAML). It is scoped by (team_name, npc_name, directory_path). Facts and concepts carry generation numbers and origin tags.
Search methods (choose the right one):
1. Keyword search — fast substring match over fact statements.
`kg_search_facts(engine_or_kg, "keyword")` → List[str]
2. Embedding search — semantic cosine similarity via vector embeddings.
`kg_embedding_search(engine_or_kg, query="...", embedding_model="nomic-embed-text",
embedding_provider="ollama", similarity_threshold=0.6, max_results=20)`
→ List[dict] with 'content', 'type', 'score'
3. Link search — graph traversal (BFS/DFS) starting from keyword-matched seeds.
`kg_link_search(engine_or_kg, query="...", max_depth=2, breadth_per_step=5,
strategy="bfs", max_results=20)`
→ List[dict] with 'content', 'type', 'depth', 'path', 'score'
4. Hybrid search — combines keyword + embedding + link, boosting results

How to install
mdr add npc-worldwide/npcpy/knowledge_graph_skill@sha256:c7e4d0a292f7fa41The line at the top of this page pins the label git:20260620.da69752, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
