What they did
1) Download Amazon invoice PDFs into a local folder and have access to your FSA reimbursement portal. The source used the Justworks Optum Financial Reimburse myself page. 2) Give Claude Code the folder and portal, and ask it to extract each invoice's eligible amount and order date, skipping duplicate invoices. 3) Use Playwright MCP for the browser interaction and file uploads. Authenticate to the claim portal in the browser being controlled so the agent can fill the reimbursement form and attach the corresponding PDF. 4) Have it complete the first submission, then reuse the working interaction for the remaining unique invoices. Finish with the claims submitted in the portal.
How it went
The author reports about a dozen claims submitted roughly two minutes after the working approach was established; reimbursement approval was not reported.
Worth knowing
In this December 2025 trial, the Chrome extension required manual file selection. These are historical interface observations.
