New Feature

Every task gets its own worktree and branch, created from the latest origin/main. Never build on main, and never reuse another agent's worktree or branch.

Harness deltas — read first

• Claude Code: the harness creates and manages worktrees itself (under .claude/worktrees/<name>). Skip steps 3–4 below (no manual git worktree add / remove), and keep the harness-assigned branch name. Steps 1–2 and 5 still apply.
• Cursor-managed worktrees (branches named worktree-*): same idea — keep the assigned branch and worktree, apply steps 2 and 5.
• Any other harness: follow all steps.

Steps

1. Sync: git fetch origin.
