AI Summary
This release introduces foundational TypeScript SDKs for sandbox resource management, enhances OpenHands agent integration with sub-second startup latency, improves SDK stability through lifecycle and pod resolution hardening, and refines testing benchmarks and documentation.
Key Highlights
- Introduced the foundational TypeScript client (`agentic-sandbox-client`) for managing `SandboxClaim` lifecycles and watching sandbox readiness.
- Added `AgentSandboxWorkspace` to enable OpenHands agents to bind to pre-warmed pods with sub-second startup latency and pool-level authentication.
- Fixed a Python SDK interpreter shutdown race condition by switching `AsyncSandboxClient` process exit cleanup to a synchronous client.
- Refactored runtime burst benchmarking to classify claim latency into Green (≤1s), Grey (>1s), and Cold zones for better observability.
- Expanded Gateway API documentation and examples to include Istio and other providers, moving beyond GKE.
New Features
- TypeScript SDK Resource Layer with OpenTelemetry tracing support.
- OpenHands Workspace Integration with direct pod IP access.
- Gateway API support for Istio and other providers.
- Command Governance Policy Example for client-side command filtering.
- Sandboxd Quickstart and deployment topology configurations.
- Interactive sandboxed-tools agent loop extraction into `pkg/agent` package.
Full Release Notes
# 🚀 Announcing Agent Sandbox v1.0.1! We're excited to announce the release of Agent Sandbox v1.0.1! This release introduces the foundational TypeScript SDK for sandbox resource management, adds a first-class OpenHands agent workspace integration, hardens SDK lifecycle teardown and pod resolution, refines testing benchmarks, and resolves key bugs across documentation, metrics, and examples. ### Key Highlights #### SDKs & Integrations * **TypeScript SDK Resource Layer (#976):** Introduced the initial TypeScript client (`agentic-sandbox-client`) under `clients/typescript/` for managing `SandboxClaim` lifecycles, watching sandbox readiness, and optional OpenTelemetry tracing. * **OpenHands Workspace Integration (#1488):** Added `AgentSandboxWorkspace`, enabling the OpenHands agent SDK to bind to pre-warmed Agent Sandbox pods with sub-second startup latency, supporting direct pod IP access, sandbox-router mode, and pool-level authentication. * **Python SDK `atexit` Cleanup Fix (#1512):** Switched `AsyncSandboxClient` process exit cleanup to a synchronous client to resolve an interpreter shutdown race condition that caused sandbox resource leaks. * **SDK Pod Name Fallback (#1467):** Ensured Go and Python SDKs correctly fall back to the Sandbox name when the legacy `agents.x-k8s.io/pod-name` annotation is present but empty. #### Testing & Reliability * **Runtime Burst Benchmarking Improvements (#1485):** Refactored `TestRuntimeClassBurstRecovery` to provision fresh warm pools per iteration, eliminating stale controller expectations and classifying claim latency into clear Green (≤1s), Grey (>1s), and Cold zones. * **Accurate Metric Documentation (#1443):** Corrected Prometheus metric `HELP` strings and label documentation across internal metrics collectors to match controller behavior. #### Examples & Documentation * **Sandboxd Quickstart & Topologies (#1416):** Added an end-to-end Go SDK quickstart for `sandboxd` along with dedicated runtime container and binary-injection deployment topology configurations. * **SandboxClaim Label-Domain Allowlist Docs (#1530):** Documented the `SandboxClaim.spec.additionalPodMetadata.labels` allowlist and improved controller rejection error messages to reference the `agent-sandbox-config` ConfigMap. * **Command Governance Policy Example (#1456):** Added an example demonstrating client-side command classification and pre-execution filtering before dispatching commands to a running sandbox. * **Sandboxed Tools Refactoring (#1482):** Extracted the interactive sandboxed-tools agent loop into an importable `pkg/agent` package with a dedicated CLI. * **Gateway API Examples(#1331, #1471):** Expanded Gateway API documentation beyond GKE to include Istio and other providers, and audited manifests, schemas, and instructions across the examples repository. ### Installation #### Standard Install (Core + Extensions) Recommended for most users and GitOps engines (Argo CD, Config Sync, kustomize): ```bash kubectl apply -f https://github.com/kubernetes-sigs/agent-sandbox/releases/download/v1.0.1/sandbox-with-extensions.yaml ``` #### Selective Install Install components separately: ```bash # Core only: kubectl apply -f https://github.com/kubernetes-sigs/agent-sandbox/releases/download/v1.0.1/sandbox.yaml # Extensions (opt-in): kubectl apply -f https://github.com/kubernetes-sigs/agent-sandbox/releases/download/v1.0.1/extensions.yaml ``` #### Python SDK ```bash pip install k8s-agent-sandbox==1.0.1 ``` -------- ### Contributors We extend our sincere thanks to all contributors to this release: @Oneimu, @adibmbrk, @aditya-shantanu, @app/dependabot, @briankhoi, @dongjiang1989, @esposem, @hchenxa, @janetkuo, @justinsb, @karimad, @khirotaka, @kincoy, @lunarwhite, @pujitha24, @sairajp-rewind, @tomergee, @vvoronko ### New Contributors * @adibmbrk made their first contribution in https://github.com/kubernetes-sigs/agent-sandbox/pull/1486 * @khirotaka made their first contribution in https://github.com/kubernetes-sigs/agent-sandbox/pull/976 **Full Changelog**: https://github.com/kubernetes-sigs/agent-sandbox/compare/v1.0.0...v1.0.1
