- Draft comment:
Removal of the early return (if not should_send_prompts()) ensures token counts are always recorded. Confirm this is intentional and that no sensitive prompt data is recorded when prompts should be suppressed. - Reason this comment was not posted:
Comment looked like it was already resolved.
2. packages/opentelemetry-instrumentation-langchain/opentelemetry/instrumentation/langchain/callback_handler.py:208
- Draft comment:
Consider using isinstance(generation.message.content, str) instead of 'is str' to accurately detect string content. - Reason this comment was not posted:
Comment was on unchanged code.
3. packages/opentelemetry-instrumentation-langchain/opentelemetry/instrumentation/langchain/callback_handler.py:163
- Draft comment:
Removing the early return now always processes token counts even when prompts are disabled. Confirm this is the intended behavior. - Reason this comment was not posted:

- Draft comment:
Consider replacing 'if generation.message.content is str:' with isinstance(generation.message.content, str) for correct type checking. - Reason this comment was not posted:
Comment was on unchanged code.
