Paste this into Claude with your current tool list:

"Here is every AI tool I am currently paying for or using regularly: [LIST TOOLS AND MONTHLY COST].

Audit this stack as a solo founder with limited time and budget. Tell me:
1. Which tools have overlapping functionality I am probably paying for twice.
2. Which tools I would feel the most pain from losing in week one.
3. Which tools I could replace with a well-crafted Claude prompt at zero marginal cost.
4. Which category in my stack is the weakest, meaning the biggest gap between what I need and what I have.
5. If I had to cut 40% of this spend today, what goes first and in what order.

Be specific. Name the tools. Do not hedge with 'it depends on your workflow' unless you actually need more information from me."

Run this quarterly. Stack debt compounds.
