What changed upstream

harbor-framework/harbor merged #1559 and #1578, which add docker-compose support to the ISLO environment provider and officially document Islo alongside Daytona as a cloud sandbox that supports multi-container tasks.

The upstream docs now explicitly state: "Daytona and Islo support multi-container deployments. Modal, E2B, Runloop and Tensorlake do not currently support multi-container environments."

Skills updated

harbor-task-creator

  • Multi-Container Tasks section: added a "Cloud provider support" note naming Daytona and Islo as the only cloud providers that support compose mode, and calling out Modal/E2B/Runloop/Tensorlake as unsupported
  • Common Pitfalls table: new row for "Using docker-compose with unsupported cloud provider"
  • GPU Notes in task-toml-reference: added IsloEnvironment to the list of non-GPU backends
  • Environment Backends table: added islo row and a Multi-Container column

harbor-cli

  • Environment Backends table: added Islo row with multi-container note; added multi-container annotation to Daytona row

Not updated

  • harbor-adapter-creator: no upstream changes touched adapter interfaces
  • The Modal Sandbox.mkdir deprecation fix (#1630) is an internal implementation detail with no user-facing impact on task authoring or CLI usage

Generated by Claude Code

ISLO now supports docker-compose multi-service tasks (harbor-framework/harbor#1559).
The upstream docs also officially list Islo alongside Daytona as the only cloud
providers that support multi-container mode.

- harbor-task-creator: note Daytona + Islo as compose-capable providers in the
  Multi-Container Tasks section; add pitfall row for compose + unsupported provider
- task-toml-reference: add islo row and Multi-Container column to backends table
- harbor-cli: add Islo to the Environment Backends table
