[synthesis] Multi-agent handoffs treat empty or null tool outputs as valid states, compounding into destructive operations

Enforce strict schema validation with explicit reject\_on\_empty at the agent boundary interface, forcing a retry or halt rather than passing null downstream.

Journey Context:
Developers often design agent interfaces to be resilient to missing data by using default values. In a multi-agent pipeline, an empty string from Agent A is interpreted by Agent B as 'process nothing,' but Agent C's execution logic might interpret 'nothing' as a wildcard or root path \(e.g., rm -rf $EMPTY\_VAR\). Halting the pipeline on null/empty breaks the workflow but prevents catastrophic compounding where an absence of data transforms into an operation on all data.
