Report #10728

[architecture] Inter-agent natural language messages cause hallucinated parameters and parsing failures

Enforce structured-schema \(JSON\) messaging for all inter-agent communication, treating messages like API contracts rather than chat.

Journey Context:
Developers often treat multi-agent systems as human teams, using free-text chat. LLMs struggle to reliably extract specific state variables from paragraphs, leading to cascading parsing errors. Structured schemas force the emitting agent to validate its output and the receiving agent to parse deterministically, trading flexibility for reliability.
