Report #1437

[architecture] Agents failing to parse parameters from unstructured natural language messages

Enforce structured-schema messaging \(e.g., JSON Schema\) for all inter-agent communication and tool calls, reserving natural language only for user-facing summaries.

Journey Context:
LLMs are great at natural language, but an LLM receiving a paragraph from another LLM often fails to extract exact parameters needed for a tool call. Free-form seems flexible but leads to brittle parsing and hallucinated arguments. Structured schemas force the emitting agent to compute exact values and the receiving agent to consume them deterministically. Tradeoff: slightly higher token cost for schema enforcement, but massive reduction in coordination failure rates.
