Keep one 502 writer per path and restore the base token-cache handling. - Check the token endpoint after the cache lookup, still before any credential acquisition. - Document 429 and 5xx classification as implemented, and drop tests that repeat retained assertions through the same code path. Signed-off-by: Shiju <shiju@nvidia.com> * refactor(providers): trim token-grant failure tests and supervisor API Cut the token-grant failure tests to one test per distinct behavior across core, gateway, supervisor, CLI and Go, and replace the 794-line closure E2E with status assertions in the existing route-recovery E2E: the refused grant appears in sandbox status with the response's request ID, code, stage and upstream status, and the matching grant's later success clears it. - Pin the live provider snapshot with one helper used by inspected and fallback forwarding, and inject selector-matched grants through inject_for_selectors, which borrows the pinned context. Move the test-only wrapper into test_support. - Drop the 35-second wrappers around the gateway grant RPC. The shared channel bounds the connection attempt and the gateway bounds its token-service calls. - Log the token service's OAuth error and error_description, without control characters and limited to 256 characters each, with the request ID in the gateway or supervisor log. Status and the workload response still carry only the bounded cause. - Keep one check that an untrusted token-service certificate cannot assert a cause. Signed-off-by: Shiju <shiju@nvidia.com> * fix(providers): restore test import and features lockfile The injection tests named EndpointObservationSender through the parent module, which no longer imports it. The features suite lockfile kept the tonic TLS dependency that the removed E2E fixture added. Signed-off-by: Shiju <shiju@nvidia.com> * test(providers): fix body-bound fixture width and table type Pass the response-size width as a named argument; an implicitly captured constant panics at runtime. Name the mutation type in the validation table for Clippy. Signed-off-by: Shiju <shiju@nvidia.com> * test(providers): pad exact-bound body without a format width MAX_TOKEN_RESPONSE_BYTES exceeds u16::MAX, the largest format width, so the padded fixture panicked. Pad with repeat_n as before. Signed-off-by: Shiju <shiju@nvidia.com> * test(server): update public RPC schema hash after rebase Main added the ListProvidersRequest label selector. The merged public schema hash comes from the Branch Checks storage_proto test output.

Important
New in OpenShell 0.1.x: a stable release cadence, new isolation primitives, an expanded extension surface, and new APIs. Read the 0.1.0 upgrade guide.
OpenShell is the safe, private runtime for fleets of autonomous AI agents. Agents are most useful when they can read files, install packages, call APIs, and use credentials. OpenShell gives them that capability without giving them unrestricted access to your data, secrets, or network. You declare what each agent can touch in a policy, and OpenShell enforces it.
How It Works
OpenShell governs what agents can do in two ways: it instruments the kernel to enforce policy on every file access, system call, and network connection at runtime, and it uses formal verification to check what a policy change would allow before it is applied.
- Kernel-level enforcement. Each agent runs in an isolated sandbox. Kernel controls confine which files it can access and which system calls it can make, and every network connection passes through a policy check before it leaves the sandbox. Agents never see real credentials; OpenShell adds them only to requests bound for approved endpoints.
- Formally verified policy changes. Before a policy change is approved, OpenShell uses formal verification to flag risky new access it would grant, such as reaching a new host with credentials or calling a new API method, so those changes wait for human review.
See Architecture for how the gateway, supervisor, and sandbox fit together.
Quickstart
You need Linux, macOS on Apple Silicon, or Windows with WSL 2 (experimental), plus Docker, Podman, or host virtualization. See the Support Matrix for details.
curl -LsSf https://raw.githubusercontent.com/NVIDIA/OpenShell/main/install.sh | sh
openshell sandbox create --name demo
The installer sets up the CLI and a local gateway. The default sandbox image is minimal Ubuntu with no agent installed. To run a real agent, follow Run Your First Agent: it runs OpenCode against a free OpenRouter model and shows how to approve new access as the agent needs it.

Agent Skills
Install the public OpenShell skills for your coding agent:
npx skills add NVIDIA/OpenShell
The skills teach your agent to drive the OpenShell CLI, write sandbox policies, and debug gateways and inference routing. They live in skills/ and work without an OpenShell source checkout.
SDKs
SDKs connect applications to an OpenShell gateway. They do not install the CLI. Use the same OpenShell release for the SDK and the gateway when possible.

OpenShell is built agent-first: it is developed with the same agent-driven workflows it enables. See CONTRIBUTING.md for development setup and the contribution workflow, and AGENTS.md for repository coding conventions.
Telemetry
OpenShell collects anonymous telemetry, limited to operational categories and counts, to help improve the project. It does not collect sandbox names, hostnames, file paths, prompts, credentials, provider or model names, or user content. To disable it, set OPENSHELL_TELEMETRY_ENABLED=false on the gateway, or server.telemetryEnabled=false for Helm installs. You can also compile telemetry out entirely. See Telemetry for details and the community telemetry reports for published usage trends.
