Coordinator Mode
Coordinator Mode is for work too big for a single prompt. It takes a high-level task, breaks it into parallel subtasks that each run in their own git worktree, and then carefully merges the results back — with two human gates and a verification pass along the way so the parallelism never costs you control.
Decompose
Section titled “Decompose”You hand Coordinator a high-level goal and it decomposes it into parallel subtasks, each isolated in its own worktree. If decomposition fails, a banner offers a Retry rather than leaving you stuck.
Two gates
Section titled “Two gates”- Gate 1 — approve the plan. Before any work starts, you review the proposed breakdown and a cost estimate and approve the plan.
- Gate 2 — review the merged diff. Before anything reaches your main branch, you review the combined diff of all subtasks. Nothing merges silently.
Apollo verification at Gate 2
Section titled “Apollo verification at Gate 2”Gate 2 is backed by a verification step. Before merge, Apollo mechanically checks each subtask’s claims against the actual diff — a deterministic git and grep layer plus a single interpretive model call — and surfaces any divergence between what a subtask said it did and what the diff shows. Each divergence expands with Investigate, Accept, or Send-back actions, so you resolve mismatches deliberately instead of trusting a summary.
