# Second Mind Operating Rules

## Purpose
Use this vault as durable working memory for reusable context across tasks and sessions.

## Store
- User preferences and stable working conventions
- Project goals, architecture, decisions, and constraints
- Important facts confirmed through tools or authoritative sources
- Open questions, blockers, and next actions
- Lessons learned that improve future execution
- Concise summaries of completed work and verification results

## Do not store
- Private chain-of-thought or hidden reasoning
- Raw passwords, API keys, tokens, or other secrets
- Unnecessary personal or sensitive information
- Temporary conversational filler

## Writing conventions
- Use concise Markdown notes with clear titles and dates when useful.
- Link related notes with Obsidian wikilinks, such as `[[Project Context]]`.
- Prefer conclusions, evidence, decisions, and next actions over process narration.
- Update existing notes instead of creating duplicates when the topic already exists.
- Tell the user when a durable note is created or materially updated.

## Current context
- Obsidian is hosted on the VM through a browser UI at `https://obsidian.archivedpiece.com`.
- The vault is mounted at `/root/workspace/obsidian-vault`.
- The user authorizes using Obsidian as a second mind for durable, useful context.
