feat: add Tenki Cloud compute provider - #3242
Conversation
Add Tenki Cloud (https://tenki.cloud) as a compute provider for managed agents, alongside E2B, Daytona, Modal, Fly.io, Docker and local. - TenkiCompute implements ComputeProviderProtocol (provision / execute / shutdown / get_status / upload_file / download_file / list_instances), running tools in disposable Tenki microVMs. Sync SDK wrapped via run_in_executor, matching the existing providers. - Registered as "tenki" in the compute barrel, the _resolve_compute factory, and the compute-provider hint sets. - Uses only stable Tenki features (exec + file I/O). Default stock image installs pip packages on demand; set metadata["tenki_image"] for a custom image. Auto-resolves workspace/project from the API key. - Enabled via TENKI_API_KEY; optional `tenki` extra (tenki-sandbox). - Unit + live (skipped-by-default) tests mirroring the E2B/Daytona suites.

In `@src/praisonai/praisonai/integrations/compute/tenki.py`:
- Around line 33-40: Update the TenkiCompute docstring example to configure the
image through the metadata key consumed by _provision_sync, replacing the
ineffective ComputeConfig image argument while preserving the existing
provisioning and execution flow.
- Around line 67-84: Update _resolve_ids to validate explicitly configured
workspace and project IDs instead of silently falling back. If _workspace_id is
set but absent from identity.workspaces, raise an error; if _project_id is set
but absent from the selected workspaceβs projects, raise an error. Preserve
first-entry fallback only when the corresponding ID is unset.
- Around line 158-165: Update _shutdown_sync so self._sandboxes retains the
instance until sandbox.terminate() succeeds; only remove instance_id after
confirmed termination. If termination raises, keep the sandbox tracked and
preserve the warning log so status/listing and a later retry can reconcile the
running resource.
- Around line 60-62: Update the ImportError handling around the Tenki SDK import
to capture the original exception and chain it when raising the installation
guidance error. Preserve the existing message while using the caught exception
as the explicit cause.
- Around line 281-312: Secure package installation in _install_packages_sync by
applying the same pip specifier validation and per-token shlex.quote handling
used by managed_local.pyβs _install_packages_in_compute; apply equivalent safe
quoting and validation to npm_pkgs before constructing the bash commands,
rejecting malformed entries rather than interpolating them. Preserve the
existing installation and warning behavior for valid packages.

β¦eanup) The maintainer's review bot flagged these but couldn't push to a fork, so applying directly: - Raise on a configured-but-unknown TENKI_WORKSPACE_ID/PROJECT_ID instead of silently using the first workspace/project (wrong-workspace billing). - shlex.quote every pip/npm spec (command-injection hardening). - Honour a non-default ComputeConfig.image, not just metadata["tenki_image"]. - Respect ComputeConfig.networking (restricted -> allow_outbound=False). - Fail provisioning and tear down the sandbox when package install fails (no false RUNNING / leaked sandbox). - Terminate before dropping the handle in shutdown, so a failed terminate keeps the sandbox tracked for retry instead of silently leaking it.

- get_status/list_instances now refresh remote Tenki state (sandbox.refresh + .state) instead of trusting the local map, so a server-side idle timeout no longer surfaces as RUNNING while execute() hits a dead sandbox.

Reads the 'unchanged default = use stock image' sentinel off ComputeConfig's dataclass field default instead of hardcoding "python:3.12-slim", so the image-selection logic can't silently drift if that default changes (CodeRabbit out-of-diff nit).

Thanks @coderabbitai β the out-of-diff findings, addressed in Fixed β magic-string default ( Skipped, with reasoning:
|
- networking: allow_outbound now keys off the real enum β only 'unrestricted' gets outbound; 'limited' (also used for --no-networking) disables it. The old check compared against a nonexistent 'restricted' value, so outbound was never actually disabled. - get_status/list_instances: a refresh() *exception* is now treated as unknown (assume running) rather than STOPPED, so a transient outage no longer hides a live, still-billing sandbox. A successful refresh with a non-RUNNING state still reports stopped. - failed-install teardown: terminate() before dropping the local handle, so a failed terminate keeps the sandbox tracked instead of leaking it (matches the shutdown path). - don't log raw pip/npm specs (can carry private-index URLs/tokens); log counts.

The skipped items are also reasonable calls β the Tip: You can customize Greptile's behavior for this repo with |
β¦KI_AUTH_TOKEN - managed_local.provision_compute() now forwards `networking` and `metadata` into ComputeConfig. Without this they were dropped, so Tenki's allow_outbound / tenki_image (the first provider to read them) always saw defaults regardless of the caller's request. (Greptile: 'networking policy is dropped') - TenkiCompute credential resolution now matches the SDK's precedence (auth_token -> TENKI_AUTH_TOKEN -> TENKI_API_KEY), so is_available agrees with what Client() resolves; docstring + is_available test updated.
