# Find past decisions

recall, ask and about look up earlier decisions, answer questions from them, and say what the record knows about a thing.

None of these tools change the record.

## recall

Before proposing or making a decision, an agent calls `recall` to check whether something like the decision has been decided before, and how the earlier decision went. `recall` returns earlier decisions with why each was made, what was expected, and the verdict once the decision has been judged.
