Tools

• Dates use YYYYMMDD format. Default: current month (1st to today).

• Calendar months use YYYYMM format. Default: current month.

• whooing_entries filters are applied after fetching the date-range results from Whooing. Use a larger limit when searching busy periods.

• whooing_search_entries uses Whooing's server-side filters first (item, memo, account, amount range) and paginates with the max cursor when needed.

• account_name matches account titles case-insensitively, so account_name: "Game" can narrow results to a game expense category without looking up its account ID first.

• When account_name matches multiple accounts, search tools split the query per account so each request can still use Whooing's server-side account filter.

• min_money and max_money filter whooing_entries by amount.

• query and keywords match against both item and memo; item_contains and memo_contains target one field.

• item and memo pass through Whooing's raw search syntax. Use these for exact item matches, * wildcards, item detail parentheses, memo AND terms, and ! exclusions.

• sort_column accepts entry_date, item, money, total, l_account_id, or r_account_id; sort_order accepts desc or asc.

• Entry-list date ranges are validated before calling Whooing because entries.json supports at most one year per request.

• For efficient broad searches, prefer item_contains, memo_contains, account filters, and amount filters over generic keywords; query is optimized as server-side item-or-memo search.

• whooing_duplicate_candidates groups entries with the same date, amount, accounts, and item; set include_memo to make memo part of the duplicate key. Use account/item/amount filters to keep duplicate scans efficient.

• whooing_account_activity accepts either account_id or account_name and summarizes only matching entries.

• Search tools cap internal Whooing requests with max_api_calls to stay within API rate guidance.

• whooing_account_activity also tries Whooing's account-specific aggregate APIs for daily changes, item totals, and client totals.

• whooing_monthly_summary uses report_summary.json with rows_type=month for direct monthly income/expense totals.

• whooing_bulk_add_entries validates account IDs for each row before creating it and reports partial failures.

• section_id defaults to WHOOING_SECTION_ID env var.

• Write tools resolve account types automatically from the account cache. Use whooing_accounts to look up account IDs first.
