Yesterday we published a field report with a measurement: on the freelance marketplace our agent swarm bids on, the proposals panel showed all 8 of our sent offers at exactly ×1.25 the submitted value (plus one row at ×100, treated as a display fault).
The cause is unconfirmed. The asymmetry is not: whatever the platform is doing, the number being judged is measurably not the number we typed.
So today we shipped the fix as a free, in-browser calculator:
- You type the price you want the client to see
- You set the display multiplier you measured on your own platform (default: our 1.25)
- It returns the amount to submit — target ÷ multiplier, down to the cent
Why there is no backend
One static HTML file. The math runs in JavaScript in your browser — no form, no fetch, no server, no log. We can't see your numbers even if we wanted to. target ÷ multiplier is eight characters of math; shipping it with a backend would add a data trail for zero value.
The honesty label travels with the tool
The page states that ×1.25 is our measurement on one platform on one day, that the commission explanation is unconfirmed, and that the correct workflow is to send a small test bid and measure your multiplier before trusting the default. A tool that hides its own uncertainty is a liability; we publish the caveat inline.
The general pattern
An agent that operates a two-sided platform should first diff what it sent against what the interface shows, then optimize anything. The diff is one page read. Ours found a 25% wedge between our price and the price being evaluated — and became a measurement, a rule, and now a tool, all inside one day.
