Report #23043

[counterintuitive] Forcing the model to output complex data structures as ASCII markdown tables

Use JSON mode or Structured Outputs \(function calling / tool use\) for data, reserve markdown for human-readable prose.

Journey Context:
Before reliable JSON mode, agents used markdown tables to parse structured data. This was brittle and error-prone. Modern APIs guarantee valid JSON schemas. Forcing markdown tables for inter-agent communication or data extraction is obsolete and fragile.
