Helping you build agents that demonstrably work. A growing ecosystem of projects — usable together or individually — for composing, evaluating, and understanding agent behavior. Experiments that prove the approach works, with published data and reproducible results.

## Highlights

What's genuinely new and cool across the lab right now.

<CardGroup cols={2}>
  <Card title="Run a workflow step in Anthropic's cloud" icon="cloud" href="/projects/agent-workflow">
    `ManagedAgentStep` hands one step of your workflow to Claude Managed Agents — a full hosted sandbox with bash, files, and web. Same graph; swap a single step between local JVM, Temporal, or Anthropic's cloud.
  </Card>

  <Card title="Speak the latest Agent Client Protocol" icon="plug" href="/projects/acp-java-sdk">
    Tracks ACP 0.14.0 — elicitation (agents ask *you* for structured input), session fork & resume, and provider config — dropping a Java agent straight into Zed, JetBrains, and VS Code.
  </Card>

  <Card title="Evaluate any agent, any framework" icon="gavel" href="https://blog.pollack.ai/here-comes-the-judge/">
    Agent Judge scores output from Spring AI, LangChain4j, Koog, or any CLI agent through one judge / jury layer — LLM and RAG judges (faithfulness, hallucination), plus tooling to evaluate the evaluators. **Read the deep dive →**
  </Card>

  <Card title="Provably CVE-clean dependencies" icon="shield-check" href="/projects/agentworks-bom">
    The AgentWorks BOM ships only behind a 9/9 convergence gate (plain / Boot 3.5 / Boot 4) — every consumer gets one coherent, vulnerability-free dependency set, verified in CI, not by hand.
  </Card>

  <Card title="Trace Claude and Gemini in one format" icon="binoculars" href="/projects/agent-journal">
    Agent Journal captures Claude *and* Gemini CLI runs into one portable trace + cost schema — one analysis layer across runtimes, no per-vendor lock-in. New in 1.5.0.
  </Card>

## Active release train

The whole suite ships as one coordinated train, pinned by the [AgentWorks BOM](/projects/agentworks-bom) — currently **1.15.0**, spanning a dozen libraries all shipped within the last month.
