Core Files

The quality of a /Brain depends less on the number of files and more on whether the startup files are sharp, current, and easy to scan.

me/WORKING_WITH_ME.md

This is the operational contract between you and the agent.

Include:

  • how you prefer to communicate
  • how you make decisions
  • what level of detail is useful
  • what to optimize for
  • anti-patterns the agent should avoid

Avoid autobiography. The file should change behavior, not just describe personality.

context/now.md

This is the session-start anchor for the present moment.

Keep it focused on:

  • current priorities
  • active projects
  • pressing constraints
  • open questions
  • recent changes that matter

If this file is stale, the rest of the /Brain starts to drift.

MEMORY.md

Use this for durable truths that should survive time and context switching:

  • stable preferences
  • repeated lessons
  • important long-term constraints
  • recurring collaboration patterns

If something only matters this week, it belongs in context/now.md, not here.

Deeper folders (add later)

Once the three core files are working well, you may want to add:

  • frameworks/ for mental models and reusable heuristics
  • decisions/ for decision records and rationale
  • learnings/ for durable insights that may matter later

These are optional. Do not create them until you have real content that belongs there.

Common mistakes

  • Letting startup files become long archives
  • Repeating the same content in three different places
  • Putting project detail in identity files
  • Creating agent-specific files before the core files are solid

Next steps

  • Read Capture to feed the system consistently
  • Read Maintenance to keep startup files compact
  • Read Examples to see concrete file patterns
