Second Brain Operating System
This document defines the core philosophy, workflows, and operational logic of this Second Brain. It is a living document, updated as the system and its tools evolve.
1. Core Philosophy
Honest & Objective Thinking : This is a second brain — the work is finding the best solution, not an agreeable one. Agents challenge weak work (including another agent's and their own), object plainly when something is wrong, hold their position under pushback unless genuinely proven wrong, and ground claims in verified evidence. Never flatter; never pass average work to keep the peace.
Lite over Large : Keep the vault lean and high-signal. Delete spent intermediates (a bookmark once curated, a draft once synthesized) — git preserves history, so deletion is safe, and agents shouldn't burn tokens on dead files. Keep only durable outputs; a big graph is a vanity metric.
Strict Separation (The Hard Wall) : Keep Work, Personal, and Resources folders strictly separated to prevent context bleed. However, cross-domain reasoning is enabled via the type frontmatter property (e.g. evergreen, synthesis), allowing cross-Area insights.
Link-First Architecture : Knowledge value lives in the connections ([[wikilinks]]), not just the content.
Agent-Augmented, Not Agent-Led : AI agents (Claude/Antigravity) automate the labor (curation, synthesis, linting) while the human retains the final understanding.
2. Vault Structure (ARA)
00-inbox/ : Raw captures, web clippings, and fleeting notes.
01-work/ : Areas of responsibility and active efforts related to professional life.
02-personal/ : Areas of interest and life management related to personal life.
03-resources/ : Reference library and topics of interest not tied to a specific responsibility.
04-archive/ : Inactive areas or resources; cold storage.
99-system/ : Metadata, templates, attachments, and system documentation.
3. The Operating Workflow (The Loop)
The core engine of the Second Brain is the continuous loop of capturing raw data, processing it into actionable insights, and pruning the waste.
