Walkthrough

The do_rag_query method in tasks/hivemind/agent.py was refactored to remove a previously commented-out multi-agent Crew orchestration. The method now directly instantiates a single RAG tool and agent, updates the system instructions, executes the agent, and manages the result, simplifying the control flow.

Changes

File(s) Change Summary
tasks/hivemind/agent.py Removed commented-out multi-agent Crew setup; simplified do_rag_query to use a single agent and tool with updated prompt instructions.

Poem

A bunny hopped through tangled code,
Multi-agent plans it once bestowed.
Now, with a single agent's might,
Queries pass through, clear and bright.
Simpler paths, the answer found—
One hop, one tool, all streamlined down! 🐇✨

182-184: Fix type inconsistency in state management.

The last_answer field is defined as CrewOutput | None (line 21) but is now being assigned a string value from result["output"]. This creates a type mismatch that could cause runtime errors in other parts of the code.

The do_history_query method still assigns a CrewOutput object to last_answer, creating inconsistent behavior. Apply this fix:

-        result = agent_executor.invoke({"input": self.state.user_query})
-        self.state.last_answer = result["output"]
+        result = agent_executor.invoke({"input": self.state.user_query})
+        # Create a CrewOutput-compatible object or update the state type definition
+        from crewai.crews.crew_output import CrewOutput
+        self.state.last_answer = CrewOutput(
+            raw=result["output"],
+            pydantic=None,
+            json_dict=None,
+            tasks_output=[],
+            token_usage={}
+        )

Alternatively, update the state type definition to accept string values:

-    last_answer: CrewOutput | None = None
+    last_answer: CrewOutput | str | None = None

158-186: Add error handling for agent execution.

The agent execution lacks error handling, which could cause the workflow to fail unexpectedly if the RAG tool or LLM encounters issues.

Add proper error handling:

-        result = agent_executor.invoke({"input": self.state.user_query})
-        self.state.last_answer = result["output"]
-        self.state.retry_count += 1
+        try:
+            result = agent_executor.invoke({"input": self.state.user_query})
+            self.state.last_answer = result["output"]
+            self.state.retry_count += 1
+        except Exception as e:
+            logging.error(f"RAG query execution failed: {str(e)}")
+            self.state.last_answer = f"Error processing query: {str(e)}"
+            self.state.retry_count += 1
+            # Consider whether to retry or stop based on error type

Learning: The RAGPipelineTool class in tasks/hivemind/query_data_sources.py has a design with class-level attributes (community_id and enable_answer_skipping) set in the setup_tools classmethod, which could cause concurrency issues if multiple instances run in parallel with different parameters. This has been acknowledged as a future improvement point to be addressed later.

Learning: In the agents-workflow project, "HivemindWorkflow" and "AgenticHivemindTemporalWorkflow" are two distinct workflows. The QueryDataSources class in tasks/hivemind/query_data_sources.py is designed to interact with "HivemindWorkflow", which is separate from "AgenticHivemindTemporalWorkflow" defined in tasks/agent.py.
