Build the pricing page

make a pricing page from docs/plans.md with a monthly / yearly switch

I’ll build it with your Tailwind theme and the four plans from the doc.

Ran pnpm test — 42 passed

Done. The page reads the plans from the doc, the switch shows yearly prices, and the tests pass.

Every public route now allows 100 requests a minute per API key and answers 429 with a Retry-After header past that. Want a test for the header too?

Plan usage alerts

email people when they pass 80% of their weekly limit

Thought 4s

Read lib/limits.ts

Searched usage events

plans/usage-alerts.md+42

The plan is in usage-alerts.md. One question before I build:

Question

When should the email go out?

1At 80% only

2At 80% and at 100%

3Let each plan decide

PlanGLM-5.3

usage-alerts.md limits.ts

plans › usage-alerts.md

Usage alerts

Tell people before a limit stops them: one email when the week passes 80%, sent once per week and never twice.

Trigger

The usage writer in lib/limits.ts, after each charge, when the weekly share crosses 80%.

Email

What is used, what is left, and when the week resets in the person’s own time zone.

3 tasks

Record the alert in usage_windows so it sends once

Add the alert email template

Test the 80% crossing and the weekly reset

Add a task…

Works on its own, checks its own work
It runs your commands and your tests, fixes what fails, and hands you one clean diff to review.

Fix the flaky checkout test

checkout.test.ts fails about one run in five on CI, fix it

Ran pnpm test checkout — 1 failed

The test sleeps 500 ms and hopes the payment has landed. It should wait for the order.paid event instead.

Fixed: twenty runs in a row pass. Ready for review.
