+
+## Tech Stack
+- Next.js 15 + TypeScript + Tailwind CSS
+- SQLite + sqlite-vec (vector search)
+- Anthropic (Claude) + OpenAI (GPT) models via Vercel AI SDK
+- 3-panel UI: Nodes | Focus | Helpers
+
+## Quick Start
+```bash
+git clone https://github.com/bradwmorris/ra-h_os.git
+cd ra-h_os
+npm install
+npm rebuild better-sqlite3
+scripts/dev/bootstrap-local.sh

+```
+
+Open http://localhost:3000 and enter your API keys (OpenAI + Anthropic).
+
+## Agent System
+**Orchestrator (Easy Mode):** GPT-5 Mini - DEFAULT - fast, cheap orchestration
+**Orchestrator (Hard Mode):** Claude Sonnet 4.5 - deep reasoning (toggle via UI)
+**Oracle (Wise ra-h):** GPT-5 - complex workflows, multi-step planning
+**Delegates:** GPT-4o mini - spawned for write operations, extraction, batch tasks
+
+Tools available: queryNodes, queryEdge, searchContentEmbeddings, webSearch, think, executeWorkflow, createNode, updateNode, createEdge, updateEdge, youtubeExtract, websiteExtract, paperExtract
+
+## Workflows System
+- **Code-first registry:** Defined in `src/services/workflows/registry.ts`
+- **Integrate workflow:** Database-wide connection discovery for focused nodes
+  - 5-step process: plan → ground → search → contextualize → append
+  - Finds 3-8 strong connections across your database
+
+## Database
+- SQLite at `~/Library/Application Support/RA-H/db/rah.sqlite`
