ios-simulator-browser

Mirror an iOS Simulator into the Codex in-app browser and render SwiftUI previews from importable Swift packages in that simulator with hot reload. Use when a user wants to watch or interact with an iOS app in the browser, see a SwiftUI preview outside Xcode Canvas, iterate live on a preview, or capture browser-visible simulator proof.

Quality

Content

100%Weight 40%Scale 1-3

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, token-efficient skill body with executable commands, clear sequencing, validation checkpoints, and a clean one-level-deep bundle split. It avoids explaining concepts Claude already knows.

Dimension	Reasoning	Score
Conciseness	Lean body that assumes Claude's competence — no explanation of what a simulator or SwiftUI preview is — with every line earning its place via executable commands or specific guidance.	3 / 3
Actionability	Provides copy-paste-ready bash for serve-sim and an exact `node <skill-root>/scripts/swiftui-preview-browser.mjs` invocation with documented flags (`--package-target`, `--device`, `--preview-filter`).	3 / 3
Workflow Clarity	Sequenced browser workflow with a cleanup trap, a stale-helper recovery step, and an explicit validation checkpoint — 'Verify that a real frame is rendering... A loaded page alone is not proof'.	3 / 3
Progressive Disclosure	Body is an overview pointing one level deep to real bundle files (`scripts/swiftui-preview-browser.mjs`, `lib/`, `templates/`) that hold the heavy project-generation logic, keeping the skill file appropriately thin.	3 / 3
	Total	12 / 12 Passed

Description

100%Weight 40%Scale 1-3

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description with concrete capabilities and an explicit Use-when trigger clause using natural user language. It is concise without padding and clearly distinguishes the skill.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'Mirror an iOS Simulator into the Codex in-app browser', 'render SwiftUI previews from importable Swift packages', 'with hot reload' — matching the top anchor.	3 / 3
Completeness	Explicitly answers both what (mirror/render/hot reload) and when via the 'Use when a user wants to...' clause, satisfying the top completeness anchor.	3 / 3
Trigger Term Quality	Natural user phrasing is well covered: 'watch or interact with an iOS app in the browser', 'see a SwiftUI preview outside Xcode Canvas', 'iterate live on a preview'.	3 / 3
Distinctiveness Conflict Risk	The narrow niche of iOS Simulator mirroring into the Codex in-app browser plus SwiftUI preview rendering is distinct and unlikely to trigger for unrelated skills.	3 / 3
	Total	12 / 12 Passed
