Vault argues back. Pulls your own history to challenge current thinking. Use when making decisions, proposing architecture, or before committing to a direction. The vault is not a yes-man -- it remembers what you've learned the hard way.
Bridge unrelated vault domains. Find structural analogues between different areas. The vault's link graph knows connections you haven't seen.
Surface unnamed patterns from recent vault activity. Reads N days of notes and finds recurring themes you haven't explicitly named. The vault notices what you don't.
Promote scattered vault mentions into dedicated notes. When an idea, pattern, or concept reaches critical mass (3+ mentions across contexts), it deserves its own page. Graduate it from scattered references to first-class citizen.
Ingest external content and REWRITE existing vault pages with new context. Not just "add a note" -- one source touches 5-15 existing pages. Resolves contradictions, updates claims, creates synthesis pages. The vault grows by integration, not accumulation.
Save everything worth keeping from the current conversation to the Obsidian vault. Use when conversation produces decisions, research, tasks, project updates, or insights. Also triggers on session wrap-up ("done", "that's it", "thanks").
Load vault context progressively -- identity, navigation, current state. Use at session start or when context about the vault is needed. Token-budgeted: start light, go deeper only as needed.
Obsidian vault as compiled knowledge base. Use when user says ingest, compile, query, lint, evolve, or asks questions that should come from a knowledge base. Also triggers on 'init kb', 'new topic', 'health check', 'what's missing'.
