Agno v3.1.4
Agno v3.1.4 introduces isolated sandboxed execution for ClaudeAgent and CodexAgent via Docker or Amazon Bedrock AgentCore, featuring persistent checkpoints, warm turns, and AgentOS API support.
Why this signal matters
Agno release v3.1.4 adds sandboxed harness execution for ClaudeAgent and CodexAgent, running processes in isolated per-session environments backed by Postgres lease-binding and checkpoints rather than on the host. Two sandbox providers are introduced: DockerSandbox (customer-operated, hardened containers with dropped capabilities, bounded tmpfs, and kernel freezer pause/resume) and AgentCoreSandbox (Amazon Bedrock AgentCore Runtime inside Firecracker microVMs). Warm sandbox turns allow session reuse within a configurable window (default 300 seconds), significantly reducing turn latency (e.g., 4.6s vs 8.2s on Docker, 3.3s vs 8.2s on AgentCore). Turn recovery fails explicitly if native conversation state cannot be verified. Additionally, AgentOS integrates sandboxed runs through standard durable queue endpoints with idempotency keys, background/streaming execution, cancellation across replicas, and support for up to 16 attachments (max 512 KiB total) staged into checkpoints.
Actionable summary
Agno v3.1.4 adds isolated sandbox harnesses for ClaudeAgent and CodexAgent using DockerSandbox or AgentCoreSandbox. State persistence relies on per-turn checkpoints stored and leased via Postgres. Features include warm computer reuse, attachment validation, and integration with AgentOS run endpoints.

What builders should check
- Install harness SDK extras using 'agno claude' or 'agno codex' if using sandboxed ClaudeAgent or CodexAgent.
- Update provider imports: use 'agno.sandbox.docker' (including DockerCheckpointTransfer) and 'agno.sandbox.agentcore'.
- Provision a Postgres database when deploying sandboxed agents with AgentOS to handle coordinator lease bindings and avoid startup failure.
- Ensure runtime environment builds are generated using the provided cookbook scripts ('build image.py' or 'agentcore setup.py') before deploying sandboxes.
