Tutorials

A guided path, each step a walkthrough you run yourself with the output you should expect. Start with Your first plugin, then follow the steps in order. The first two need a deployment installed with --development; see Build with an AI agent. Each needs SDK 0.36.0, CLI 0.1.60 and a deployment on chart 0.1.538.

Step	Tutorial	What you learn
1	Change your plugin's page, live	Edit the reference plugin's pages, watch each save run, break it on purpose, fix it, and release.
2	Record a holdings statement	A plugin with the custody role that records a holdings statement and a holding against one of your accounts.
3	Structure a plugin	One class per role, the SDK's helpers for what every plugin of a role does alike, settings and secrets declared once, and tests that hold each class to its role's suite.
4	Fast data retrieval	Subscriptions instead of polling, the lake's hot layer and from_memory, latest and listing reads, asking only for what a page shows, batching, and never reading again per request.
5	Build a live page	Values worked out from views with pages.live_values and LiveValue: source, age, staleness counted only in session with FX_WEEK, a bounded update rate, and never a blank cell.
6	Analytics	The engine's measures rather than your own, worked out on change or on a cadence, kept per key, and off the request path.
