Research direction

Compare the SDK's TaskType.java with the server's TaskType.java at Conductor 3.32.0-rc.9, starting with the SDK enum entry that currently ends at CALL_MCP_TOOL. Verify that TaskType.of("AGENT") and the other three names resolve to their corresponding enum values, with no builder work required until the agent task API is stable.

Description

bug

Summary

Four task types added to the Conductor server in 3.32.0-rc.9 (PR conductor-oss/conductor#1288)
are absent from the SDK's TaskType enum. Calling TaskType.of("AGENT") silently returns
USER_DEFINED instead of the correct value.

Server baseline

Conductor 3.32.0-rc.9

Missing values

The server's TaskType.java has:

PULL_WORKFLOW_MESSAGES,
AGENT,
GET_AGENT_CARD,
CANCEL_AGENT;

The SDK's TaskType.java stops at CALL_MCP_TOOL — all four values are absent.

Impact

  • TaskType.of("AGENT") returns USER_DEFINED — silently wrong
  • No builder classes can be typed to these task types
  • SDK users writing AGENT workflows must hard-code raw strings

Evidence

Static: Compared server TaskType.java against SDK TaskType.java.

Live (2026-07-16): A raw WorkflowTask with "type": "AGENT" was registered
against Conductor OSS 3.32.0-rc.9. Server accepted the definition, confirming the type is
valid server-side — the gap is SDK-only.

Proposed fix

Add to the SDK TaskType enum:

PULL_WORKFLOW_MESSAGES,
AGENT,
GET_AGENT_CARD,
CANCEL_AGENT;

Builder classes for AGENT, GET_AGENT_CARD, and CANCEL_AGENT should follow once the
agent task API is stable.
