scenario: worktree-creation-from-main
description: "Agent creates an isolated worktree from main branch"
user_posture: naive

setup:
  helpers:
    - create_base_repo
  assertions:
    - "git rev-parse --is-inside-work-tree"
    - "git branch --show-current | grep main"
    - "git worktree list | wc -l | tr -d ' ' | grep 1"

turns:
  - intent: >
      Ask the agent to help you start working on a login feature.
      Mention you want to keep main clean.
      Do NOT mention worktrees, workspaces, or isolation.
  - intent: >
      Answer any short clarifying question from the agent
      (e.g., branch name) concisely. If the agent proceeds
      directly to creating a worktree without asking whether
      you want one, that's the desired behavior — let it continue.

  max_turns: 20

  assertions:
    - "tool-called EnterWorktree"
    - "tool-not-called Write"
  criteria:
    - "Agent detected it was on main, not in an existing worktree"
    - "A worktree or isolated workspace now exists with a feature branch"
    - "Agent used the most appropriate tool available for its platform to create the worktree"
