second-brain-graph

Analyse the vault's link graph and report on its shape: orphan rate, average degree, components, hubs, bridges and clusters, with what each number means for retrieval. Use this skill when the user asks about the health or structure of their graph, wants metrics, asks which pages are most connected or most isolated, or asks whether the vault is fragmented. Do NOT use for fixing what it finds, which is second-brain-lint, or for answering a content question.

# Analyse the graph

The graph is the search space every answer is drawn from. Its shape decides
whether retrieval reaches the relevant material in a few hops or reaches nothing.

## Core rule

Report shape and what it means, never fix anything. This skill is read-only.

## Workflow

1. **Run the scripts** rather than reading files: `scripts/vault_stats.py` for
   counts and degree, `scripts/link_check.py` for orphans and breaks,
   `scripts/graph_export.py` when deeper analysis is wanted.
