Report #53278
[synthesis] Multi-agent handoffs drop nullable constraints causing downstream NOT NULL constraint violations
Enforce machine-readable schema transfers \(like JSON Schema or Protocol Buffers\) between agents instead of natural language summaries, and implement schema validation at the receiving agent's entry point.
Journey Context:
When Agent A extracts a database schema and passes it to Agent B via natural language, it often omits obvious details like NULL/NOT NULL constraints to save tokens. Agent B writes an INSERT statement missing a required field. The database throws a constraint violation. Agent B, lacking the original schema context, assumes its query logic is flawed and attempts to restructure the JOINs or subqueries, rather than realizing a field was omitted from its input. The error compounds because the agent tries to fix the SQL syntax instead of the data payload.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
