An HR coordinator is staging a large task: first Claude extracted every policy change from a 60-page handbook update into a table, and next it will draft an FAQ for staff. Before moving on to the FAQ, what should she do?

Answer: A — Check the table against the handbook, correct any gaps or errors, and pass the corrected table to the FAQ step.

Decomposition only helps if each stage's output is verified before the next stage builds on it. Option (a) checks against the source and passes forward corrected results. (b) lets any extraction error flow into the FAQ, where it's harder to spot. (c) throws away the work the FAQ should rest on. (d) relies on Claude's self-assessment rather than a check against the handbook.
