lgtm @monoppa let's submit a pr upstream |
Add @voltagent/sandbox-tenki, a WorkspaceSandbox provider that runs each execute_command inside a disposable Tenki Linux microVM via @tenkicloud/sandbox, mirroring the existing E2B / Blaxel / Daytona providers. TenkiSandbox is built on the SDK's session run() API, which returns a process handle and is the only primitive that can enforce a per-command timeout and AbortSignal. It forwards cwd/env/stdin natively, keeps stdout and stderr separate, truncates each stream at maxOutputBytes on a UTF-8 character boundary, and serializes start/stop/destroy so concurrent lifecycle calls observe one transition at a time. createTenkiToolkit adds optional expose_preview_url and authorize_ssh_key tools, kept in tools.ts so consumers can omit them.

Summary
Adds
@voltagent/sandbox-tenki, a first-partyWorkspaceSandboxprovider that runs eachexecute_commandinside a disposable Tenki Linux microVM via@tenkicloud/sandbox. Mirrors the existing E2B / Blaxel / Daytona providers.What's included
TenkiSandboximplementsWorkspaceSandboxon top of the SDK sessionrunAPI: nativecwd/env/stdin, per-command timeout + abort viakill(), separate stdout/stderr streams, andmaxOutputBytestruncation. Lazy cached session (clear-on-failure), plusstart/stop/destroy/getInfo/getInstructions/getSession.createTenkiToolkit— optional preview-URL (expose_preview_url) and SSH-key (authorize_ssh_key) tools, isolated intools.tsso they can be dropped without touching the core adapter.website/docs/workspaces/sandbox.md), and a changeset (minor).SDK note / design deviation
The Tenki SDK's
session.exec()ignorestimeoutMs/signal; the real handle-based primitive issession.run(argv, { cwd, env, stdin })(returns aProcessRunHandlewithstdout/stderrstreams,stdin,kill(), and asignalin the result). The adapter is built onrun()— it's the closest mirror to E2B'scommands.run().wait()/kill()and the only way to actually enforce timeout/abort. Output bytes are decoded withTextDecoder;CommandTimeoutErroris caught →timedOut.Testing
pnpm --filter @voltagent/sandbox-tenki typecheck— cleanpnpm --filter @voltagent/sandbox-tenki build— CJS + ESM + d.ts (SDK externalized)pnpm --filter @voltagent/sandbox-tenki test— 57 tests passing, 100% coverage (SDK fully mocked, no network)Live end-to-end check against a real microVM was not run (no
