Handoff is a specialized tool designed to facilitate the transfer of accepted artifacts to various downstream collaboration surfaces. In the context of an open design run, the process is not complete until the artifact is placed in a location where users can continue to work on it. This skill serves as the critical 'push it somewhere' stage, complementing the diff-review process by ensuring that artifacts are not just created but effectively integrated into the user's workflow.

The skill accepts an artifact set that has been approved through the diff-review process and allows users to specify an export target from a predefined list of surfaces. These surfaces include options such as CLI, desktop applications, web publishing, Docker containers, GitHub for pull requests, Figma for design files, and various code agents like Cursor, Claude Code, and Codex. This flexibility ensures that users can choose the most appropriate destination for their artifacts based on their next steps in the project.

Upon execution, Handoff updates the ArtifactManifest.exportTargets[] to reflect the history of where artifacts have been pushed, maintaining an append-only record. This feature is crucial for tracking the distribution and evolution of artifacts over time, which is particularly important in collaborative environments. The skill ensures that the user’s intent is respected, preventing any unintended pushes to surfaces not on the user's list, thereby maintaining control over the workflow.

Handoff is ideal for developers and designers who need to manage the lifecycle of their artifacts effectively. By providing a clear and structured method for pushing artifacts to various surfaces, it enhances collaboration and ensures that all team members can access the latest versions of their work. Whether you are working on code, design files, or documentation, Handoff simplifies the process of sharing and iterating on artifacts in a collaborative setting.
