ios-simulator

Verify and debug native, React Native, Expo, or Flutter apps on an iOS Simulator with agent-device. Use when an agent needs to launch an app, inspect its live UI, tap, type, scroll, validate a code change, collect failure evidence, or reproduce a workflow on an iPhone or iPad Simulator.

Quality

Content

93%Weight 40%Scale 1-5

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

A tight, highly actionable skill body that assumes Claude's competence and provides copy-paste commands plus explicit error-recovery guidance. The only minor gap is that the core workflow's validation step is implicit rather than an explicit checkpoint.

Suggestions

Make the happy-path validation explicit, e.g. after 'agent-device open ...', add a step like 'Verify the app foregrounded via the interactive snapshot before proceeding.' to lift workflow clarity to a 5.

Consider a short numbered sequence for the normal-task flow (open → verify snapshot → act) so the ordering and checkpoint stand out at a glance.

DimensionReasoningScore

Conciseness

Lean and efficient throughout — it never explains what an iOS Simulator, React Native, or the CLI is; every line is operational guidance (install guardrail, do-not-probe list, open command, error handling) that earns its place.

5 / 5

Actionability

Fully executable, copy-paste-ready commands — 'npm install -g agent-device@latest', 'agent-device open <app-or-bundle-id> --platform ios --foreground', and a block of help topics with inline comments — cover the common cases.

5 / 5

Workflow Clarity

Clear sequence (require install → open with --platform ios → follow snapshot/error hints → stop-and-ask if unavailable → read help only when specialized) with explicit error-recovery feedback, but the happy-path validation is implicit ('follow the interactive snapshot') rather than an explicit verify checkpoint, leaving a minor gap.

4 / 5

Progressive Disclosure

A self-contained 28-line skill under the 50-line threshold with no need for external reference files; content is logically grouped (install, normal driving, error handling, specialized help) and the help-topic pointers are one-level navigation into the tool's own help system.

Description

100%Weight 40%Scale 1-5

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

An exemplary description: concrete actions, natural trigger synonyms, explicit what-and-when guidance, and a distinct niche, all in concise third person. It matches the top anchor on every dimension.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'launch an app, inspect its live UI, tap, type, scroll, validate a code change, collect failure evidence, or reproduce a workflow' — giving comprehensive coverage rather than vague language.

5 / 5

Completeness

Explicitly answers both: what ('Verify and debug ... apps on an iOS Simulator with agent-device') and when ('Use when an agent needs to launch an app, inspect its live UI ...'), with concrete trigger phrases.

5 / 5

Trigger Term Quality

Covers natural user terms including synonyms and platforms — 'iOS Simulator', 'iPhone or iPad Simulator', 'React Native, Expo, or Flutter', 'tap, type, scroll' — matching the comprehensiveness of the 5 anchor.

5 / 5

Distinctiveness Conflict Risk

Narrow, clearly bounded niche — iOS Simulator app driving via the specific 'agent-device' tool — with distinct triggers and minimal overlap risk; uses third person.
