# Quick reference

This page gives the calls each common task takes, in the order your AI coding tool makes them. Each row links the guide that explains the steps, their options, and their refusals. Each key limit below links the section that states its figure or, for a figure your plan sets, says where to read it.

## Key limits

Each line says what a limit bounds and links the section that states its figure or says where to read it. Plan figures and prices can change without a release, so read them there or with `read_plan_quotas`.
