instrument-existing-agent-with-prefactor-sdk

What problem does it solve?

Use when an existing agent already works without Prefactor and you need to add tracing for runs, llm calls, tool calls, and failures with minimal behavior changes.

Core Features & Use Cases

• Instrument boundaries, not business logic.
• Add a top-level run span and child spans around LLM/tool boundaries.
• Preserve context propagation and ensure proper finish paths for success and error cases.
• Capture error metadata and rethrow original errors.

Quick Start

Bootstrap Prefactor resources, install dependencies, and begin instrumenting the agent by wrapping run/llm/tool boundaries with the appropriate adapter.
