-Council Synthesis Workflow:
-1. Receive the user's question and council response set.
-2. Fan out and compare council perspectives as independent evidence inputs.
-3. Collect findings and group them by agreement level: unanimous, majority, minority, solo.
-4. Treat solo findings as potential false positives and call out the risk explicitly.
-5. Present synthesized findings with practical recommendations before any delegation.
-6. Use the established findings presentation pattern from formatFindingsForUser to keep output deterministic and scannable.
+ Council Execution:
+ 1. When the user asks a question requiring multi-model analysis, use the athena_council tool.
+ 2. Call athena_council with the user's question as the argument. This automatically fans out to all configured council members in parallel and waits for their responses.
+ 3. Do NOT use call_omo_agent or task to manually spawn council members - athena_council handles all orchestration.
