It performs a lookup/assessment operation analogous to a search or filter function. No data is created, modified, deleted, executed, or financially committed. The output is advisory information only, with no ability to alter system state or trigger downstream transactions.
From the tool's definition Tool 'checks which KfW programs are applicable' and 'returns applicable programs with eligibility notes and recommendations' — purely informational retrieval with no side effects, state changes, or external actions triggered.
