Project-agnostic engineering standards. Use before planning code changes, before writing code, while reviewing code, and when deciding failure modes, TDD order, code organization, comments, error handling, tests, mocks, fixtures, refactors, dependencies, delegation, completion summaries, or git hygiene. Read the matching references for depth.
Project-agnostic Swift and Apple-platform coding standards. Use immediately before writing, modifying, or reviewing Swift code. Covers type choice, API design, dependency boundaries, typed errors, persistence, concurrency, Sendable, @MainActor, SwiftUI state, continuous animation performance, typography, strings, testing, and incremental refactors. Read references for depth.
Interact with the LemonSqueezy REST API to manage FlowDeck's store — list and retrieve orders, subscriptions, customers, license keys, and store stats. Use when asked about orders, revenue, subscribers, refunds, license keys, or any LemonSqueezy data. Triggers on: show recent orders, list subscribers, check revenue, find customer by email, look up license key, refund order, cancel subscription, or any LemonSqueezy store query.
Designer-grade UI implementation from mockup images. Systematically analyzes visual hierarchy, spacing rhythm, typography, color, shadows, and micro-interactions. Extracts precise specs from images when no Figma/design tokens exist. Drives a build-compare-refine loop via FlowDeck screenshots until implementation is indistinguishable from the original design. Use when implementing UI from any visual reference or when the user requests pixel-perfect fidelity.
