Bulk-import data into the fin app (a local personal-finance dashboard at http://localhost:8888) across 7 domains — alerts, transactions, holdings, income, ledger, balance sheet items, watchlist. Auto-detects type from input, asks upfront for account / snapshot date / format ambiguities, shows a confirmation gate before any write, and is idempotent (skips duplicates server-side and previews them client-side). Triggers on phrases like "import to fin", "导入到 fin", "fin 导入", "bulk add transactions to fin", "把这些持仓加进 fin", or any time the user provides tabular data (CSV or pasted text) plus intent to write it to the fin app. Use fin-accounts (not this skill) when the user wants to set up balance accounts WITHOUT importing data.
Batch create balance accounts (parent + sub-accounts) in the fin app. Two modes — (1) parse account names from user input (text/CSV: each line a "Parent" or "Parent/Sub"); (2) seed from the bundled starter_accounts.json template covering ~30 common broker/bank/wallet/card hierarchies (anonymized real reference). Always shows a confirmation gate before creating. Triggers on phrases like "set up fin accounts", "在 fin 里建账户", "fin 建一批账户", "create balance accounts", "use the starter accounts template", "init fin accounts". Use fin-import (not this skill) when the user has data to import — fin-import will inline-create missing accounts on its own.
