What they did
Claude Code wrote his multi-agent trading system and NotebookLM did the research. A second model reviewing the code caught that an agent could sell a position it never bought.
Result (as claimed)
His lesson: never let the model that wrote the code be the only one checking it.
Tools they used
Cost: Claude Code: from $17/mo; NotebookLM: free plan, paid from $4.99/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.

Related use cases
Let Claude and Codex work on trading charts like a human would
Built OpenChart, an open-source TradingView-style workspace where your existing AI plans annotate and act on charts.
Build client apps and automations solo while keeping a full-time job
After 12 years in management he started coding again with Cursor, Lovable, Claude Code and Codex. In two years he built more than 20 apps and automation projects for local clients, including a career tool, a startup and business agents, without the offshore team he once hired.
Turn Claude Code into a machine-learning quant lab that rejects overfit models
Following Marcos Lopez de Prado's ML trading workflow, you give Claude Code market data, labeling rules, features, costs and risk limits. It applies triple-barrier labels, builds XGBoost, LightGBM, random forest and neural network variants, runs purged K-fold and CPCV validation, stresses costs and slippage, and rejects models that only work because of leakage or lucky splits.
Cut Cursor, OpenRouter and Zapier bills to zero by moving AI work onto flat seats
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.
