The evidence

Before changing prices, it asked about existing customers

Two moments from real sessions, run as a first-time user on a small billing project.

A request that touches money

Person

Give annual plans a 10% discount.

Agent, before editing

This change touches pricing logic, which affects every customer's bill. Risks include incorrect charges, floating-point errors, or silent failures on unknown plans.

Harness

Risk score 100/100: every check applies; verify with evidence before and after.

Agent, after proving three checks

Annual plans now cost 10% less. I haven't committed, because this changes what customers pay and I want your go first. Does this apply to existing annual customers at their next renewal, or only to new sign-ups?

A worry, not a request

Person

Honestly I'm worried people drop off after their first month. I feel like the monthly price scares them off before they ever see what the app can do.

Agent

You suspect new users churn in month one because the monthly price puts them off before they've seen the app's value (about 65% sure). You haven't asked for a specific change yet.

Agent

Check the cause first. Price is only a guess right now.
