openshell-sdk
openshell-sdk is the shared async Rust client for OpenShell gateways. It owns
gRPC channel setup, TLS, OIDC refresh, and the Cloudflare Access tunnel so the
CLI, the TUI, and language bindings share one client implementation. Callers
pass an explicit bearer token; the SDK does no filesystem access and no
gateway-name resolution.
Two layers
OpenShellClient— the curated, sandbox-focused surface: health, sandbox CRUD, readiness/deletion waits, and non-streaming exec.raw— direct access to the generated tonic clients for RPCs the curated surface doesn't yet cover (inference, providers, policy, logs, settings, SSH, forwarding).
Auth and refresh
The curated surface drives OIDC refresh automatically: proactively before a
request and reactively on Unauthenticated. Refreshes are single-flight, so
only one is in flight at a time.
The plain raw_grpc/raw_inference accessors do not refresh; they return a
client bound to the current token. When a refresher is wired, use
raw_grpc_fresh/raw_inference_fresh to refresh before the call, and
force_refresh to recover after a raw RPC returns Unauthenticated.
The SDK consumes a Refresh trait that the caller implements; it does not run
the OIDC browser flow itself. Its non-interactive refresh-token exchange also
accepts scopes that identity providers may require to select the API resource
for the refreshed access token.
Transport modes
- Plaintext (local development)
- Server-authenticated TLS (system roots, or a pinned private CA via
ca_cert) - OIDC bearer over HTTPS (gateways behind an OAuth2/OIDC IdP)
- Cloudflare Access tunnel (hosted gateways)
- Insecure TLS (development/debug; certificate verification disabled)
mTLS (client certificates) is not supported.
Public surface
OpenShellClient::connect(ClientConfig) returns a connected client exposing
health, create_sandbox, get_sandbox, list_sandboxes, delete_sandbox,
wait_ready, wait_deleted, and exec. Curated types (SandboxSpec,
SandboxRef, Health, ListOptions, ExecOptions, SandboxPhase) use
SDK-shaped enums rather than raw proto integers. Failures map to a typed
SdkError with a discriminable kind.

Notes
- Async-only. Tonic is async-native; callers needing a blocking call can wrap with their own runtime.
- The curated surface will grow as more RPCs graduate from
raw.
