About
Java runtime for deploying agents and running them inside a tool sandbox — the JVM port of the AgentScope framework.
What it does
It turns a Java agent handler into a network service with managed state, session history, memory, and isolated tool execution. A reactive pipeline converts framework messages and streaming events into a common format, assigns sequence numbers, tracks status, and exposes the agent through configurable protocols.
Why it's ranked here
The design covers more than serving model output. It joins framework adapters, lifecycle handling, persistent-service abstractions, sandbox connections, and deployment tooling in one Maven project. The strongest evidence is the concrete AgentScope integration and reactive event pipeline. Broader framework support and observability remain incomplete.
What's good
Framework-specific message and event conversion sit behind explicit adapter interfaces, keeping the runtime core separate from agent libraries. Streams carry created, active, failed, and completed states with ordered events. Local deployment supports protocol selection, custom endpoints, middleware, CORS configuration, lifecycle hooks, and replaceable state, memory, session, and sandbox services.
Tradeoffs
The quick start requires Java 17, Maven, service wiring, and a custom handler, so adoption is not configuration-only. The documented working integration centers on AgentScope Java, while Spring AI Alibaba and Langchain4j are described as forthcoming. Comprehensive tracing and visualization are explicitly under development.
How to use it well
Use it when a Java team needs to wrap an agent as a streaming service while retaining control over framework adapters, state services, and sandbox infrastructure. Start with the in-memory services locally, then select Kubernetes or AgentRun for sandbox execution where appropriate. Do not count on it for complete operational tracing yet.
Technical notes+
The root pom.xml defines a Maven reactor spanning engine-core, sandbox-core, agents, web, Spring Boot starter, four sandbox extensions, and maven_plugin. engine-core/src/main/java/io/agentscope/runtime/engine/Runner.java converts requests through MessageAdapter and StreamAdapter, emits Reactor Flux<Event> sequences, supplies missing session and user IDs, collects completed messages, and maps stream failures into failed responses. web/src/main/java/io/agentscope/runtime/LocalDeployManager.java starts a servlet Spring Boot context, scans protocol packages, and registers CORS, custom routes, and filters. web/src/main/java/io/agentscope/runtime/app/AgentApp.java loads environment, system, and optional file properties, defaults to in-memory services plus a Docker-backed SandboxService, and uses reflection for provider substitution. engine-core/src/main/java/io/agentscope/runtime/engine/Runner.java also contains an empty init() implementation, while shutdown() only changes health and logs completion.
