Apple App Store screenshot and app preview specifications.

Thorough distillation of Apple's complete Human Interface Guidelines across all six platforms (iOS, iPadOS, macOS, tvOS, visionOS, watchOS) — component-by-component best practices, hard specs (tap targets, type sizes, color tokens), per-platform deltas, and choose-the-right-component decision tables, with a synced reference corpus that tracks Apple's updates.

Audit and consolidate Claude's per-project auto-memory directory, deduping, repairing, and pruning with per-cluster approval.

Write expressive git commit messages with Gitmoji.

Comprehensive Excalidraw mastery: authoring .excalidraw scene files by hand (the JSON format, element model, arrow/text binding, and a diagrams-that-argue design methodology), plus the @excalidraw/excalidraw developer API (React component, initialData, the convertToExcalidrawElements skeleton API, restore, SVG/PNG/clipboard export, and Mermaid-to-Excalidraw), shipped with scripts to validate a scene, render it to PNG, and insert icon-library elements — grounded in the official Excalidraw documentation.
