# Safe by default: never overwrites an existing file. If a file already exists at
# the destination, it's kept and the new one is written as <file>.new for manual review.

Next steps:

  1. Open SOUL.md and fill in your agent's identity.
  2. Open USER.md and fill in who you are.
  3. (Optional) Open TOOLS.md for your local aliases and shortcuts.
  4. Read MANUAL.md at least once — it's the operating philosophy.
  5. Tell your agent: "Read AGENTS.md and MANUAL.md and follow them."

Files saved as *.new indicate you already had your own. Diff them at your leisure.
