Agent worktrees

Chat: RESPONSE.md. Full method: METHODOLOGY.md.

Operating order

1. Should we isolate? (§1)

≥2 agents on this repo → yes. User/product says share → obey. Overlapping structural files → serialize even with worktrees.

2. Already isolated?

If you're already in a worktree (common dir ≠ toplevel of a single checkout) and a branch exists for this task → skip create; run setup if share links missing.

3. Create branch + worktree (§2.1)

Off main. Prefer Linear branch name when tracked. Don't double-create Claude Code's claude/<name> trees.

4. Share env (§2.2)
