      "_comment": "frontend-tools 'Sunset' pill — 1st leg: emit change_background tool call. The Strands SDK mints its OWN UUID tool_call_ids for client-tool results (confirmed via the aimock journal: follow-up requests carry lastToolCallId=<uuid>, never the canonical call_d5_* id), so the post-tool follow-up cannot pin on toolCallId like langgraph-python does. AND the 3-pill probe runs all pills in ONE thread, so hasToolResult is permanently true after the first pill — gating on it makes pills 2/3 match their content leg on the first turn and never call the tool. We use sequenceIndex:0 (proven on built-in-agent, same Responses-API id situation): gate the 1st-leg to the FIRST match of this pill's userMessage; once exhausted the bare-userMessage post-tool fixture below catches the 2nd-leg request. Per-pill userMessage keeps the sequence counters independent.",
