Parallel Agents & Worktrees

Degree of freedom: MIXED. What to split and which model [HIGH freedom]; isolated worktrees and no shared-file writes [LOW freedom — run exactly].

How to reason

1. Observe — independent tasks vs one shared file
2. Interpret — worktree / cloud / best-of-N
3. Classify — parallel-safe / must-serialize
4. Severity — two agents editing one path is a conflict, not speed

Worked example

Observe: "fix tests" and "write the README" touch different trees. Interpret: two worktrees, two agents. Classify: parallel-safe; do not also give both package.json. Merge: integrate one result at a time; compare best-of-N on the same prompt.
