[architecture] Agents hallucinating parameters when passing tasks via natural language

Enforce structured JSON schemas for inter-agent handoffs instead of free-form text, treating agent communication as an API contract.

Journey Context:
LLMs excel at natural language, but when passing exact state \(e.g., file paths, line numbers\) between agents, free-form text causes the receiving agent to hallucinate or drop parameters. Few-shot examples are brittle. The tradeoff is that schemas require upfront design and strict validation, but they eliminate an entire class of parsing errors and make handoffs deterministic.
