Obsidian Second Brain Vault for AI Agents

Purpose: This vault implements Julian Goldie's "Obsidian as 2nd Brain for AI" / Infinite Context Engine concept. It serves as the single source of truth shared memory for all your AI agents (Hermes, Leonard, Charlie, Athena, Claude, local LLMs via LM Studio, etc.).

Instead of each agent having siloed, disposable context, every agent reads from and writes back to this local Markdown vault. It becomes your portable, future-proof, vendor-independent long-term memory.

Core Architecture (Goldie + Your Stack)

Capture — Agent activity logs, conversation summaries, cron jobs, manual dumps from other AIs. (Optional: add OMI wearable later for passive screen/mic capture)
Organize — Agents (primarily Hermes or Claude Desktop) clean, structure, link, and summarize daily/weekly.
Store — This Obsidian vault (local-first, plain Markdown + YAML frontmatter). Git-optional for versioning.
Deploy — Every agent session starts by loading relevant notes from the vault (via the obsidian-second-brain skill or direct folder access in Claude Desktop / custom pipelines).

The Loop: After any meaningful agent work, the agent writes structured updates back into the vault. Tomorrow's agents wake up smarter.

Your Advantage: You already have the obsidian-second-brain cross-CLI skill installed locally. It handles self-rewriting notes, hybrid search, scheduled maintenance agents, and multi-agent access (Claude Code, Codex, Gemini, OpenCode, Hermes, Pi). This vault is the data layer that skill operates on.

PARA Organization (Projects / Areas / Resources / Archives)

Projects/ — Time-bound initiatives with clear goals and end dates (e.g. AI Research Oracle v1 launch).
Areas/ — Ongoing spheres of responsibility (e.g. AI Agent Development, Content Creation, Business Operations).
Resources/ — Evergreen knowledge, references, tools, prompts, model evals.
Archives/ — Completed or hibernated items. Move here instead of deleting.

Every note uses YAML frontmatter for agent visibility:

---
title: "Note Title"
tags: [project/ai-research-oracle, hermes-managed, priority/high]
updated: 2026-07-15
updated_by: "Hermes"
status: active
related: ["[[AI-Talk-Show-Leonard-Charlie]]"]
---

Tags + wikilinks ([[Note Name]]) are the connective tissue agents use for retrieval.

Quick Start (for your machine)

Copy this entire folder to your local machine (e.g. ~/Obsidian-Vaults/Second-Brain-for-AI/ or ~/second-brain).
Open it in Obsidian (free from obsidian.md). Install community plugins if desired: Dataview, Periodic Notes, Git (optional), Advanced URI, etc. Keep plugins minimal.
Point your agents at it:
- Claude Desktop: Open the folder as a project or use Artifacts / file access.
- Hermes / local agents: Use the installed obsidian-second-brain skill — it exposes the vault to your agents.
- LM Studio / local LLMs: Use system prompt that includes "You have access to the Obsidian vault at [path]. Use the provided tools or read relevant .md files before answering."
Run the Initialization Prompt (see Meta/Agent-Prompts.md) with Hermes or Claude to seed initial memories from what you already know about your projects.
Set up daily maintenance (cron or scheduled agent task):
- Once per day (or on demand): "Run daily Obsidian vault maintenance: summarize yesterday's activity, update project notes, prune old context, create daily log if needed."
Backup: rsync or git push to a private repo / cloud (Obsidian Sync optional). Do a full backup quarterly.

Token Discipline (Important for local RTX 3060)

Do not dump entire chat history every turn.
Use daily batch summaries only.
The obsidian-second-brain skill + scheduled agents already implement this.
When context grows, ask agent: "Reconsider and compress the last 7 days of activity into concise project updates in the vault."

Why This Unlocks Your Workflow

Leonard & Charlie (AI Talk Show): Persistent character memories, show history, episode ideas, audience feedback all live here. They "remember" across sessions without prompt stuffing.
Hermes + Athena (AI Research Oracle): Daily news pipeline outputs, source credibility notes, article drafts, performance metrics stored and queryable.
OmniRoute: Routing logic, API key rotation history, failover test results, model benchmarks in one place.
Phoenix Salon + Spa: Client photos, branding guidelines, social content calendar, A/B test results — all agent-accessible for content gen.
Future-proof: When you add a new agent or switch models (Qwen → newer), just point it at this vault. It instantly knows your entire context, goals, and history.
Self-awareness: Use Obsidian Graph or Memory Galaxy-style views to see which projects/notes are "brightest" (most updated).

Next Actions for You

Copy vault to your machine and open in Obsidian.
Run initialization with your main agent (Hermes or Claude).
Create first daily maintenance cron/scheduled task.
Add OMI later if you want passive capture (optional — your agent logs already provide strong signal).
Version the vault lightly with Git (track only the note folders, ignore .obsidian/ cache).

This vault + your existing skill + local models = a truly sovereign, compounding AI memory system.

"The vault doesn't just store what you tell it, it stores what your agents actually worked on." — Goldie

Now go build the infinite context engine. Your agents will thank you (and perform better every day).
