README.md

An agent-first Obsidian vault template based on a real multi-agent workflow.

Start simple. The full system is already in place for later.

New here? Start with START-HERE.md.

Want copy-paste AI prompts? Use ASK-AI.md.

Using an AI agent? Tell it to read README.md, START-HERE.md, VAULT.md, and AGENTS.md first. It should explain the workflow and ask for your first project before editing files.

What This Is

This vault gives humans and AI agents one shared source of truth:

  • VAULT.md is the map.
  • AGENTS.md is the operating manual.
  • NOW.md is the current state.
  • Projects/ /HANDOFF.md keeps agent continuity.
  • !1 Work Log/ records real sessions.
  • !2 Briefings/ stores bot output and daily reports.
  • Backlog.md holds planned work.
  • Knowledge/ becomes the long-term wiki.
  • Agents/Skills/your-vault/SKILL.md can be installed so capable agents load your vault rules automatically.

The template ships empty by design: no private data, no fake businesses, no client examples.
