    fix(agent): collect CodeExec artifacts from ReAct tool responses (#16609)

    frostbyte_neo 发布于 2026-07-05 12:53:43 +00:00

    Summary

    The Go backend Agent component was not returning artifacts produced by
    the CodeExec tool. While the Python agent collects the "_ARTIFACTS"
    envelope from tool responses and appends artifact markdown to the final
    content, the Go agent only returned the assistant text, so generated
    images were missing from the chat output.

    Changes

    • Wire react.WithMessageFuture() in runEinoReActAgent and store the
      resulting MessageFuture in the invocation context.
    • After the ReAct loop finishes, drain the future and extract
      _ARTIFACTS entries from every tool response message.
    • Support reading the tool payload from both msg.Content and
      msg.UserInputMultiContent to match eino's tool contract.
    • De-duplicate artifacts by URL and render images as ! and other files
      as download links.
    • Add agent_artifact_test.go with a regression test that simulates a
      CodeExec-style tool response carrying an image artifact and verifies it
      is collected and formatted.

    Verification

    • go test ./internal/agent/component/... -run TestAgent_ReActAgent_CollectsArtifactsFromCodeExecTool passes.
    • go test ./internal/agent/component/... -count=1 compiles; the only
      failure is an unrelated DNS-pinning timeout test
      (TestInvoke_ProxyDNSPin).
    • gofmt clean for modified files.

    the CodeExec-generated PNG artifact.
