Report #79185
[synthesis] Agent confidently executes multiple consecutive wrong steps after an early unvalidated assumption
Inject 'assumption checkpoints' into the agent's system prompt or intermediate orchestration layer, forcing the agent to explicitly list unverified premises and call a verification tool before proceeding to dependent steps.
Journey Context:
When an agent makes an assumption \(e.g., 'the database is PostgreSQL' when it's MySQL\), it doesn't throw an error; it generates a syntactically correct but semantically invalid query. The agent uses the 'success' of step 1 to justify step 2, compounding the error. People try to fix this by adding more instructions, but the root cause is the lack of a feedback loop on premises. The tradeoff is increased latency and token cost for verification steps vs. preventing catastrophic multi-step drift. Verification is worth it because compounding errors are exponentially harder to correct.
