Vault Daydream Skill

Multi-agent system that mines the Obsidian vault for non-obvious connections between notes, mimicking the brain's default mode network. Samples random note pairs, synthesizes connections via Sonnet, filters with Haiku critic.

Inspired by Gwern's LLM Daydreaming.

Usage

/daydream

What it does

1. •Auto-detects vault root from current directory (asks if not found)
2. •Scans vault for notes modified in last 120 days
3. •Generates 50 recency-weighted random pairs
4. •Synthesizes connections (Sonnet, parallel batches of 5)
5. •Critiques and scores insights (Haiku, parallel batches)
6. •Filters for quality (average score >= 7.0)
7. •Saves insight notes to Daydreams/ folder
8. •Generates daily digest in Daydreams/digests/
9. •Appends summary to today's daily note

Output

• •Individual insights: Daydreams/YYYYMMDD-slug.md -- full synthesis with scores and wikilinks
• •Daily digest: Daydreams/digests/YYYYMMDD-digest.md -- stats + ranked top insights
• •Daily note: Summary appended under ## Daydream
• •History log: ai-research/daydream/history.json -- tracks sampled pairs for dedup

Architecture

Skill (orchestrator)
  |-- Glob/Read: scan vault, extract excerpts
  |-- Generate 50 random pairs (recency-weighted)
  |-- Task(model: sonnet) x 10: synthesize connections  <-- parallel
  |-- Task(model: haiku) x 10: critique/score insights  <-- parallel
  |-- Filter (avg >= 7.0)
  +-- Write: save insight notes + daily digest

No external dependencies -- pure Claude Code tools (Glob, Read, Write, Bash, Task).

Cost

Per run (~50 pairs): approximately $0.40-0.50 via Claude Code usage.
