SDK​

New Features​

TypeScript SDK​

  • NEW: Brand-new TypeScript SDK, published to npm (rl-rock). Supports sandbox management, filesystem operations, sync/async shell command execution, Python/Node.js runtime environments, built-in Agent support, EnvHub integration, and ESM/CommonJS dual builds (#492)

Agent Run (Harbor Style)​

  • NEW: Support Agent Run, allowing users to submit and manage agent run tasks (harbor style) via the SDK (#681)

Job OSS Artifact Mirror​

  • NEW: Add OssMirrorConfig and JobConfig.enable_oss_mirror() to support Job OSS artifact mirroring, automatically populating namespace/experiment_id from sandbox config (#708)

Sandbox Client​

  • NEW: Add auto_delete_seconds field to specify the retention time after a sandbox is stopped. Currently supports the following behaviors:

    • auto_delete_seconds = None (default): whether the sandbox is cleaned up after stop is determined by the cluster configuration

    • auto_delete_seconds = 0: the sandbox is deleted immediately after stop

    • auto_delete_seconds > 0: the sandbox is not deleted after stop
