MOC Curator

This skill uses semantic embeddings to suggest MOC (Map of Content) updates and discover new MOC opportunities.

Capabilities

•Find MOC Gaps: Notes that should be in existing MOCs but aren't linked
•Discover Clusters: Groups of orphan notes that could form new MOCs
•Detect Hub Notes: Notes with many outgoing links that could become MOCs
•Per-Note Suggestions: Which MOCs a specific note should join

Embeddings include title, summary, and first 500 characters of body content for improved semantic accuracy.

Workflow

Phase 1: Gather Context

Run the clustering script to analyze the knowledge base:

bash

python3 .claude/skills/moc-curator/scripts/cluster-notes.py --mode=full

Parse the JSON output:

•moc_updates: Existing MOCs with missing notes
•new_clusters: Orphan note clusters that could be MOCs

Phase 2: Present MOC Update Suggestions

For each MOC with gaps, show:

markdown

### [[moc-slug]] - MOC Title

Currently has X members. Suggested additions:

1. **[[note-slug]]** (score: 0.82)
   - Type: article | Tags: tag1, tag2
   - Shares tags: shared-tag

2. **[[another-note]]** (score: 0.75)
   - Type: youtube | Tags: tag3
   - High semantic similarity to existing members

Phase 3: Present New MOC Opportunities

For each orphan cluster:

markdown

### Potential New MOC: "Inferred Theme"

Common tags: tag1, tag2, tag3

Notes in this cluster:
- [[note-a]] - Note A Title
- [[note-b]] - Note B Title
- [[note-c]] - Note C Title

**Suggested MOC name**: `theme-name-guide.md`

Phase 4: User Selection (Blocking Gate)

Use the AskUserQuestion tool to ask which suggestions to apply:

yaml

question: "Which MOC suggestions would you like me to apply?"
header: "MOC Updates"
multiSelect: false
options:
  - label: "Apply all MOC updates"
    description: "Add suggested notes to existing MOCs"
  - label: "Apply all new MOC creations"
    description: "Create new MOCs from discovered clusters"
  - label: "Select specific suggestions"
    description: "Choose individual suggestions to apply"
  - label: "Skip all"
    description: "Don't make any changes"

Wait for explicit approval before making any changes.

Phase 5: Apply Changes

For MOC Updates:

•Read the existing MOC file
•Append new links to a ## Suggested section at the end

markdown

## Suggested

- [[new-note-1]] - Brief description of why it belongs
- [[new-note-2]] - Brief description of why it belongs

For New MOCs:

•
Read the writing-style skill for prose guidelines:
- •Use the Read tool on .claude/skills/writing-style/SKILL.md
- •Apply its 10 rules when writing MOC descriptions
•Create a new map note following the pattern:

yaml

---
title: "Theme Name Guide"
type: map
tags:
  - common-tag-1
  - common-tag-2
---

Description of what this map covers.

## Section Name

- [[note-a]] - What this note contributes
- [[note-b]] - What this note contributes

Phase 6: Quality Check

Run linter and type check to catch any issues:

bash

pnpm lint:fix && pnpm typecheck

If errors are found, fix them before completing the task.

Script Usage

bash

# Full analysis (MOC gaps + new clusters + hub notes)
python3 .claude/skills/moc-curator/scripts/cluster-notes.py --mode=full

# Only MOC gaps
python3 .claude/skills/moc-curator/scripts/cluster-notes.py --mode=moc-gaps

# Only orphan clusters
python3 .claude/skills/moc-curator/scripts/cluster-notes.py --mode=new-clusters

# Only hub notes (potential MOCs)
python3 .claude/skills/moc-curator/scripts/cluster-notes.py --mode=hub-notes

# Suggestions for a specific note (used by adding-notes hook)
python3 .claude/skills/moc-curator/scripts/cluster-notes.py --mode=for-note --note=slug-name

# Adjust threshold (default: 0.7 - strict)
python3 .claude/skills/moc-curator/scripts/cluster-notes.py --threshold=0.6

# Adjust minimum links for hub detection (default: 5)
python3 .claude/skills/moc-curator/scripts/cluster-notes.py --mode=hub-notes --min-links=3

Error Recovery

Issue	Resolution
No embeddings cache	Script will auto-generate embeddings
sklearn not installed	`pip install scikit-learn`
Empty results	Try lower threshold: `--threshold=0.6`
sentence-transformers missing	`pip install sentence-transformers`

Quality Guidelines

•Only suggest notes with similarity >= 0.7 (strict threshold)
•New MOCs require at least 3 notes in a cluster
•Always show the reasoning (shared tags, similarity score)
•Let the user decide what to apply - never auto-modify MOCs
