What they did
His team paid OpenRouter $10,550 in January and Cursor $2,640.85 in August 2025. They moved coding to Claude Code, ran reply drafts through Claude Code's command line on flat seats, moved enrichment calls to Codex, and replaced their Zapier automations too.
Result (as claimed)
Cursor, OpenRouter and Zapier bills have been $0 since mid-September; 5,667 September commits had a Claude co-author line.
Tools they used
Cost: Claude Code: from $17/mo; OpenAI Codex: free plan, paid from $8/mo.
Set it up
Gather the documents
Collect statements, bills, invoices or tax documents for the period you want reviewed.
Ask for an audit, not actions
Have Claude Code list findings, amounts and suggested next steps before it does anything.
Approve each action
Approve cancellations, disputes or payments one at a time. Never give an agent open-ended access to move money.
Track the result
Record what changed and what you saved so you can check it next month. This is not financial advice.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like). 2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure. 3.
