SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps you enter deep thinking mode to reflect on vault content, discover patterns, connect ideas, and surface insights. It acts as a thinking partner, guiding questions and challenging assumptions to improve clarity and direction within your vault.

Core Features & Use Cases

  • Supports angles such as digest, challenge, emerge, drift, trace, connect, ideas, and ghost to structure reflective work.
  • Writes outputs to the vault in {vault}/thinking/agent-output/YYYY-MM-DD-<angle>-<topic>.md and maintains a thinking history for review.
  • Improves decision quality by surfacing contradictions, gaps, and new perspectives during vault exploration.

Quick Start

Start deep thinking on a topic with /think digest to review agent outputs and surface vault insights.

FAQPage Schema
How do I surface insights and discover patterns in my markdown vault?

Deep thinking analyzes vault content using angles like digest, trace, and connect to surface insights and discover patterns. It identifies contradictions, gaps, and new perspectives within your thinking zones.

How do I generate new ideas from my existing notes and reflections?

Generating ideas from existing notes uses angles like emerge, drift, and ideas to move thinking into vault context. This structures reflective work to surface new directions and organize outputs from your content.

Can I use deep thinking to challenge assumptions in my vault content?

Yes, you can challenge assumptions in your vault content using the challenge angle. It acts as a thinking partner, guiding questions to improve clarity and direction by surfacing contradictions and gaps in your notes.

Where are deep thinking outputs and reflections stored in the vault?

Deep thinking outputs are written to vault/thinking/agent-output/YYYY-MM-DD-<angle>-<topic>.md. This maintains a thinking history with appropriate metadata and logs for review within your vault structure.

Do I need a configuration file to analyze vault content for insights?

Yes, you need a brain-os.config.md file in your vault. The system reads the vault location from this configuration file to properly analyze content and write results to the correct agent-output directory.

What is the best way to review and connect past reflections in a vault?

The best way to review and connect past reflections is using the trace and connect angles. These approaches structure reflective work by moving thinking into vault context to organize outputs and maintain a thinking history.
