Orca: Organizing Coding Agents with Git Worktrees
Purpose, mechanisms, getting started and boundaries
Source: stablyai/orca · stablyai
User Problem
Positioning and task fitWith several coding agents running, coordination shifts to working directories, terminals, browser checks and code review. Orca combines agents, separate Git worktrees, editing and review in a desktop workbench. It does not decide which model writes the best code; it makes separate results easier to inspect, compare and merge.
- Work on independent development tasks in parallel
- Compare alternative implementations
- Follow long tasks from desktop and mobile
Product Mechanism
Capabilities and execution- A worktree for each workstreamAgents can edit in separate worktrees, reducing direct interference in one directory. Separate directories do not resolve semantic conflicts automatically; merged behavior still needs review. Source
- From UI selection to prompt contextDesign Mode selects an element in Chromium and passes its HTML, CSS and cropped screenshot to the agent, connecting visual feedback to a specific component. Source
- Send review feedback to the agentDiff-line comments can return to the agent, with GitHub and Linear entry points in the workbench. Tasks, implementation and review feedback stay connected with less manual copying of paths and context. Source
- Remote execution and mobile follow-upSSH worktrees support remote execution, while the mobile companion provides notifications, monitoring and follow-ups. These change where work runs and is observed, not its environment dependencies, connectivity or model limits. Source
Workflow
Start with a small task- Install the desktop appChoose the official release for your platform. On macOS, keep the full Homebrew cask name to avoid an unrelated package with the same short name.
- Connect an existing agentFirst verify that the chosen CLI agent can authenticate and complete a small task, then open the repository in Orca. The workbench does not itself supply provider accounts.
- Separate comparable workCreate worktrees with a file scope, expected behavior and completion criteria. Keep requirements constant for comparisons and identify dependencies before parallel feature work.
- Review and mergeInspect diffs, return reproducible feedback and run repository checks. After merging, verify interfaces between tasks before cleaning up worktrees whose changes are safely integrated.
The trial sequence and checks are editorial guidance. Entry commands follow official documentation; this project was not executed for the article. Source

Limits and Boundaries
Constraints and selection| Boundary | Meaning | Suggested action |
|---|---|---|
| Terminal compatibility versus deeper integration | Running in a terminal does not imply identical UI integration for every agent. Source | Check output, input and session recovery for your chosen agent. |
| Telemetry and remote pairing | The README links telemetry documentation and separate mobile relay setup. Source | Read data-flow and opt-out settings before enabling cross-device features. |

Orca fits developers who regularly use several coding agents. For one short task at a time, its value comes mainly from review and browser integration rather than concurrency.
How to Evaluate Adoption
Trial scenario and verificationEvaluate a form-validation change with two agents in separate worktrees using the same requirements and test data. Compare correctness before change size and maintenance cost, rather than timing alone. Include new dependencies in the review. Orca supplies a place to compare work; the project still defines the criteria.
A minimal check creates a worktree, starts a configured agent, displays changes and returns one review comment to the conversation. Validate remote and mobile features separately.
