Smart Graph — Vault Relationship Analyzer

Query the Smart Connections pre-computed graph without reading markdown files.

Overview

Smart Connections (Obsidian plugin) pre-extracts outlinks, heading structure, and tasks from every vault note into .smart-env/multi/*.ajson files. This skill exposes that data via a Python extraction script that builds a full vault graph in seconds.

When to Use

• "What links to [[Transition-Hub]]?" — backlink discovery
• "Find orphaned notes" — notes with zero connections
• "Show me the graph around this note" — neighborhood mapping
• "What's the heading structure of X?" — block/outline view
• "Most connected notes in the vault" — hub identification
• Vault-wide relationship analysis without grepping markdown

Procedure

Step 1: Run the extraction script

# Vault summary (orphans, hubs, stats)
python3 scripts/extract-graph.py

# Backlinks to a note
python3 scripts/extract-graph.py --backlinks "efforts/current/Transition-Hub"

# Heading structure
python3 scripts/extract-graph.py --blocks "calendar/day/2026-02/20260210.md"

# 1-hop neighborhood
python3 scripts/extract-graph.py --neighborhood "000-dashboard.md"

Notes:

• Targets use vault-relative paths (no leading /, .md extension optional)
• Script reads from $VAULT_ROOT/.smart-env/multi/ (default: ~/vault/.smart-env/multi/)
• Output is JSON to stdout
• First run scans all .ajson files (~5-10 seconds for 12,000+ notes)

Step 2: Interpret results

Summary mode returns:

• stats: total_notes, total_internal_links, orphan_count
• orphans: notes with no inbound or outbound links (capped at 100)
• most_linked: top 20 notes by backlink count (target, backlink_count)
• most_outlinks: top 20 notes by outgoing link count (source, outlink_count)

Backlinks mode returns:

• target: the note queried
• backlink_count: number of linking notes
• backlinks: sorted list of all notes linking to it

Blocks mode returns:

• blocks: heading hierarchy with start_line/end_line ranges
• block_count: number of named headings
• task_lines, tasks: task locations and completion status

Neighborhood mode returns:

• outgoing: list of {target, title, line} objects for notes this note links to
• outgoing_count: number of outgoing links
• incoming: sorted list of notes linking to this note
• incoming_count: number of incoming links

Step 3: Present findings

Format results as markdown for the user. For backlinks and neighborhoods, use wikilink format [[path|display]] so results are vault-navigable.

Environment

Error Handling

Smart Connections not indexed

Cause: .smart-env/multi/ directory is empty or missing Solution: Open Obsidian and let Smart Connections finish indexing.

Note not found in index

Cause: Note was recently created or Smart Connections hasn't re-indexed Solution: Force re-index in Obsidian, or fall back to Grep for the specific file.

Stale data

Cause: Smart Connections updates incrementally; some .ajson files may lag Solution: Check file modification times in .smart-env/multi/.

Limitations

• No semantic search — embeddings require vector math; use Khoj MCP for semantic queries
• Read-only — this skill reads Smart Connections data, never writes to it
• Stale if Obsidian closed — Smart Connections only updates while Obsidian is running
• External links excluded — only vault-internal wikilinks are in the graph
• Orphan count inflated — includes node_modules/, backup/, archive directories that legitimately have no wikilinks
