Plugin Overview & Capabilities

AI-assisted organization based on the public repository snapshot. The content must be grounded in source evidence and does not replace compatibility or security verification.

source-grounded
The Blaxel Sandbox plugin integrates ephemeral Blaxel microVM execution into DeepSeek Harness. It allows DSH sessions to route filesystem, bash, terminal, and LSP operations to isolated cloud microVMs while keeping UI state, conversation history, and credentials securely on the host machine.

Key Capabilities

  • Seamlessly switch native DSH sessions between local workspace and remote Blaxel microVM sandboxes
  • Automated Git worktree snapshot packaging with credential filtering and upload to /workspace in the sandbox
  • Remote subprocess and filesystem routing without falling back to host execution on failure
  • Settings UI for OAuth authentication, CLI profile switching, image selection, resource quotas, and active sandbox lifecycle management
  • Host-isolated model routing verification preventing credential leakage into sandbox environments

Useful For

  • Running untrusted code, scripts, or LLM agent actions inside isolated microVM sandboxes
  • Offloading resource-intensive builds and subprocess tasks from local workstations to cloud compute
  • Executing development workflows across Git worktrees without risking host filesystem modifications

Who It Fits

  • Developers needing secure cloud execution environments in DeepSeek Harness
  • Security-focused teams running AI coding agents against remote sandboxes
  • Engineers using Blaxel cloud infrastructure within DSH Web

Documented Limitations

  • Moving a session from local workspace to sandbox is currently one-way without automated reverse-sync
  • A running turn cannot be migrated into a sandbox mid-execution
  • Requires a Blaxel account, workspace authentication, and compatible Node/DSH runtime helpers (e.g., node-pty, dsh-subprocess-local)

DSH Compatibility

Version-specific runtime evidence collected by DSH Plugin. A missing result means we have not tested that combination yet.

Not tested yetNo runtime compatibility tests have been published yet.

Security Signals

Objective signals discovered from package metadata and source inspection. These are not a guarantee that a plugin is safe.

No automated security signals have been published yet.
