3. Removing invalid files (e.g. containing "行程单").
4. Checking PDF contents for a mandatory missing keyword.
5. Calculating the grand total amount from all valid invoices.

Instructions for the Agent

When the user asks you to process or organize invoices (e.g., "整理 ./fapiao 里 的发票，关键字是 银河科技;腾讯"):

1. Extract Arguments:
   • dir: The target directory. If the user does not specify a directory, safely default to the current directory (.) or ask the user if it is ambiguous.
   • keyword: The target keyword to check inside the PDFs (e.g., a company name). Note: Multiple keywords can be provided separated by a semicolon ; (e.g., CompanyA;CompanyB).
2. Handle Missing Keyword:
   • You MUST prompt the user for the <keyword> if it is missing from their request. Do not guess it.
3. Execute Command:
   • Construct and run the following terminal command (replacing placeholders with extracted values): python main.py process <keyword> -d <dir>
4. Report Results:
   • After the script completes, summarize the printed results for the user (files fixed, dupes removed, files moved to <dir>/invoices, and files moved to <dir>/invoices/unknown, plus the grand total).
