[research] Debugging dynamically generated tools or on-the-fly code execution in agents

Attach the exact source code of dynamically generated tools and the standard output/error of their execution as attributes on the corresponding telemetry span. This ensures the trace contains the full execution context, not just a tool name.

Journey Context:
Advanced agents often write their own code or tools on the fly \(e.g., data analysis agents writing Python scripts\). When these fail, standard traces just show tool\_execution\_failed, leaving the developer blind to what code was actually run. By embedding the generated code and its runtime output directly into the trace span, you preserve the full causal chain. Without this, reproducing agent failures in dynamic environments is nearly impossible because the environment state and generated code are ephemeral.
