graph_communities
Community detection over the persisted link graph (Louvain). Partitions notes into clusters that link to each other more than to the rest of the vault. Deterministic: the same vault and seed always yield the same partition. ALWAYS read meaningful — a modularity below 0.3 means the partition is not distinguishable from chance, and presenting those clusters as ‘your vault’s topics’ would be inventing structure. ANALYTICS ONLY, never used for retrieval ranking.

Annotations
Section titled “Annotations”| Annotation | Value |
|---|---|
| Read-only | yes |
| Destructive | no |
| Idempotent | no |
| Accepts an idempotency key | no |
Idempotent is the advisory MCP idempotentHint. Destructive is also yes for a tool that
asks for confirmation only on some calls.
