Field note
Orca is a desktop and remote control plane for running multiple coding agents, each in an isolated Git worktree. It supports several CLI agents, keeps terminal and file state per workspace, and connects worktrees to pull requests, issues, CI checks, and review surfaces.
Isolation solves a real but narrow problem: two agents no longer write into the same checkout. It does not prove that their branches compose. Separate diffs can change adjacent contracts, duplicate migrations, reorder dependencies, or pass their own tests while failing together.
The integration layer is therefore the product. A useful fleet workflow needs task ownership, base-commit tracking, cross-branch diff review, CI on each candidate and the combined result, explicit dependency order, and a human merge gate. Orca is most interesting as the place where those artifacts become visible, not as a promise that parallelism is automatically productive.
