From aab1ad10a74d62c8e376bd8b0e2e9b8116a9e839 Mon Sep 17 00:00:00 2001 From: DHARSHAN Date: Sat, 20 Sep 2025 00:31:05 +0530 Subject: [PATCH 1/7] - __InstrumentationSettings Version 3 Introduced__ MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Added version 3 to the `InstrumentationSettings` class while maintaining version 2 as default - Ensures backward compatibility for existing users and queries - __Agent Run Spans__ - Updated span name format to `invoke_agent {gen_ai.agent.name}` for version 3 - Maintained legacy `agent_name` attribute while adding new `gen_ai.agent.name` attribute - Both attributes contain identical values for seamless transition - __Tool Execution Spans__ - Updated span name format to `execute_tool {gen_ai.tool.name}` for version 3 - Added new attributes `gen_ai.tool.call.arguments` and `gen_ai.tool.call.result` - Maintained legacy `tool_arguments` and `tool_response` attributes for backward compatibility - __Implementation Strategy__ - All changes are properly gated behind version=3 checks - Version 2 behavior remains unchanged as default - New attributes are only added when version ≥ 3 is explicitly enabled - Span name changes (critical for display improvements in #2925) are fully implemented -
