Harnesses

Most harnesses create git worktrees to run tasks in parallel. These worktrees may live inside your project or outside it entirely. Coast's worktree_dir array tells it where to look -- including external paths like ~/.codex/worktrees that require additional bind mounts.

Each page below covers the Coastfile configuration and any caveats specific to that harness.
