amazingchow Bundle

Extract a webpage into a browser semantic snapshot derived from the accessibility tree instead of screenshots, then normalize it into a Claude Code or Codex-ready text format. Use when a user gives a URL and wants page structure, actionable elements, or browser state captured as compact text with stable refs; when Codex needs to reason about a page semantically; or when a page may require authentication and Codex must detect that a manual login is required before capture. Also use for requests like "给这个网页做语义快照", "把页面整理成 Claude/Codex 可用格式", or "先判断是否需要登录再抓页面结构".

nucliweb Bundle

Intelligent network quality analysis with adaptive loading strategies. Detects connection type (2g/3g/4g), bandwidth, RTT, and save-data mode, then automatically triggers appropriate optimization workflows. Includes decision trees that recommend image compression for slow connections, critical CSS inlining for high RTT, and save-data optimizations (disable autoplay, reduce quality). Features connection-aware performance budgets (500KB for 2g, 1.5MB for 3g, 3MB for 4g+) and adaptive loading implementation guides. Cross-skill integration with Loading (TTFB impact), Media (responsive images), and Core Web Vitals (connection impact on LCP/INP). Use when the user asks about slow connections, mobile optimization, save-data support, or adaptive loading strategies. Compatible with Chrome DevTools MCP.

sethdeckard Bundle

Orient inside DeviceTerm and route to its CLI. Use when working in a DeviceTerm tab, or when a task involves driving an iOS, iPadOS, watchOS, or tvOS Simulator or a mirrored iPhone or iPad: tapping, typing, swiping, reading the accessibility tree, or managing tabs and panes. Establishes what the deviceterm CLI owns, what belongs to xcrun simctl and devicectl, and where the authoritative command reference lives.

sethdeckard Bundle

Reproduce a reported bug on a Simulator from inside a DeviceTerm tab, and capture evidence of what happened. Use when asked to reproduce, triage, confirm, or investigate a bug report, crash, or user-reported issue in an iOS, iPadOS, watchOS, or tvOS app. Sets up device preconditions with xcrun simctl, drives to the failing state with deviceterm input, and collects screenshots, accessibility trees, and device logs. Covers what changes on a mirrored physical device, where most of that tooling does not exist.

sethdeckard Bundle

Audit an app's accessibility on a Simulator from inside a DeviceTerm tab. Use when asked to check accessibility, VoiceOver labels, a11y coverage, hit target sizes, or Dynamic Type behavior in an iOS, iPadOS, watchOS, or tvOS app. Sweeps the accessibility tree for unlabeled controls and undersized touch targets, and drives text size changes through xcrun simctl.

sethdeckard Bundle

Drive an app on a Simulator from inside a DeviceTerm tab and verify what it actually did. Use when asked to test, exercise, walk through, smoke-check, or confirm a flow in an iOS, iPadOS, watchOS, or tvOS app: tapping through a screen, typing into a field, or confirming a control or label appeared. Pairs deviceterm input with accessibility reads and screenshots as evidence rather than trusting a command receipt. Covers what changes on a mirrored physical device, where structural verification is not available.
