What it does
A discount that looks like 30 percent off can take half your profit. Many sales are planned from the number that looks big, and the margin is checked after the emails are out. A price rise rolled out to every product at once can't be undone. Old strikethrough prices stay on pages long after the sale, and they can mislead your customers. This agent checks the plan first. It works out your margin at the sale price, cuts the discount five points at a time until your margin floor holds, and tells you the deepest cut that is safe. For a clearance it plans the cuts in stages. For a price rise it builds the price from the bottom up and sets a test you can undo. Once a month it lists strikethrough prices that no longer show a real discount. It never changes a live price. You approve a…

You get
- Margin and break-even ROAS for each product, at the current and planned price
- The deepest discount that keeps your floor, or a plain "no discount fits"
- Stock to have ready, or clearance stages with dates
- Sale wording, and a previewed price list to approve
Use it when
- You plan a sale, a discount code or a clearance and want to know it still pays.
- You want to raise prices and need a test you can undo.
- You think old strikethrough prices are sitting on your product pages.
How to use it
- Start a chat with the agent. In Claude Code, add it as a skill or save it in .claude/agents, then give it your plan.
- The first time, give it your product costs and your margin floor. It saves them.
- Read the margin table and the depth that holds. Change the plan if you want a deeper cut and accept the lower margin yourself.
- Approve the price list in clear words if you want it to make the change. Otherwise, change prices yourself.
- After the sale, tell it the result so the log can use it next time.
