From fd46cbd30d7bfb1648300ea83fae65b9a0b475d4 Mon Sep 17 00:00:00 2001 From: Jason Lee Date: Fri, 20 Feb 2026 03:54:02 +0800 Subject: [PATCH] fix(rig): prevent OpenAI Responses API panic on tool call IDs (#182) * fix(rig): prevent responses API panic on missing tool call IDs * style: format rig adapter * test(rig): add coverage for empty/whitespace tool call IDs Add tests for assistant tool calls with empty and whitespace-only IDs, and an end-to-end test documenting the seed mismatch limitation when both assistant call and tool result are missing IDs. * Apply suggestions from code review Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: Illia Polosukhin Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --- src/llm/rig_adapter.rs | 187 +++++++++++++++++++++++++++++++++++++++-- 1 file changed, 178 insertions(+), 9 deletions(-) diff --git a/src/llm/rig_adapter.rs b/src/llm/rig_adapter.rs index 20e82eeb..7a520989 100644 --- a/src/llm/rig_adapter.rs +++ b/src/llm/rig_adapter.rs @@ -237,11 +237,16 @@ fn convert_messages(messages: &[ChatMessage]) -> (Option, Vec (Option, Vec { // Tool result message: wrap as User { ToolResult } - let tool_id = msg.tool_call_id.clone().unwrap_or_default();
