FieldTrace is a tool designed to handle common issues in agent pipelines where fields arrive under incorrect names or numbers are passed as text. It accepts declared renames and safe conversions while validating against the target schema to refuse changes that could result in information loss.

  • The system allows explicit field renaming, such as converting "user_name" to "name".
  • It performs safe type conversions, for example turning the string "36" into the integer 36.
  • Unsafe operations, such as handling large integers that might lose precision, are automatically refused.

The author recommends using FieldTrace alongside SharedNet for teams experimenting with agent collaboration and service handoffs to ensure data contracts are maintained.
