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.
