Add LangWatch Tracing to Your Code

Determine Scope

If the user's request is general ("instrument my code", "add tracing", "set up observability"):

• Read the full codebase to understand the agent's architecture
• Study git history to understand what changed and why: focus on agent behavior changes, prompt tweaks, bug fixes. Read commit messages for context.
• Add comprehensive tracing across all LLM call sites

If the user's request is specific ("add tracing to the payment function", "trace this endpoint"):

• Focus on the specific function or module
• Add tracing only where requested
• Verify the instrumentation works in context

This skill is code-only: there is no platform path for tracing. If the user has no codebase, explain that tracing requires code instrumentation.

In Langy, do not print the change for the user to apply by hand: call code_access and follow the code-changes skill to make it on their machine or through GitHub.
