Report #83738

[synthesis] Step 1 produces subtly wrong output \(off-by-one, wrong unit\), Step 2 'successfully' processes it producing amplified error, final result is confidently wrong

Implement intermediate validation gates - for multi-step calculations, force verification of intermediate results against known constraints or sanity checks before allowing progression to next step

Journey Context:
Agents treat tool chains like pure functions where output of A feeds into B. But if A returns '150 miles' when it should be '150 km', B calculates 'time = distance/speed' and returns '2.4 hours' which looks reasonable. Without explicit intermediate validation, the error compounds silently. Sanity checks \(e.g., 'verify distance is < 50 miles for intra-city travel'\) catch unit/scale errors early before they amplify through the chain.
