LangSmith
An observability and debugging platform (from the LangChain team) for tracing, testing, and monitoring LLM applications in production — logging exactly what prompts, tool calls, and outputs happened at each step.
Think of it like
Like a black-box flight recorder for an LLM app — when something goes wrong in production, you can replay exactly what the model saw and did at every step.
Junior or senior?
Junior sounds like
Has no way to trace a bad LLM output after the fact.
Senior sounds like
Can describe actually tracing back what happened when an LLM app gave a bad answer in production.
Ask them
“When an LLM app gave a bad answer in production, how did you actually trace back what happened?”
