Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

`estimate_win_back_revenue`read-only	Same formula as https://winbackhq.com/tools/win-back-revenue-calculator/ : people lost per segment times a return rate, times price, over up to 6 months, minus the 15% fee. Default return rates: cancelled 20% (RevenueCat SOSA 2026 monthly reactivation within a year, a reference not a forecast), billing failed 10% (assumption), trial expired 5% (assumption).
`get_apple_retention_facts`read-only	Sourced facts on App Store billing retry, grace periods, win-back offers and Retention Messaging, for founders planning a win-back.
`get_winback_overview`read-only	What Winback does, who it is for, what it needs and what it does not do. Use this when someone asks how to win back churned subscribers of an iOS, Android or Stripe subscription app.
`get_winback_pricing`read-only	Winback pricing terms.

Schemas: list_tools.
