mobile-platforms

Domain knowledge for triaging and fixing .NET failures on Apple mobile (iOS, tvOS, MacCatalyst) and Android. Use when runtime-extra-platforms or mobile CI is failing, when investigating iOS, tvOS, MacCatalyst, iossimulator, tvossimulator, or Android build/test failures, or when a change touches mobile pipeline YAML, AppleAppBuilder/AndroidAppBuilder, code signing, provisioning, simulator/emulator startup, platform conditionals, or NativeAOT-on-mobile behavior. Covers failure triage (infrastructure vs code), CI pipeline structure, platform-specific code paths, and NativeAOT compilation on mobile.

Quality

Content

75%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 well-structured, information-dense skill body that uses tables and concrete repo paths to give actionable triage guidance without over-explaining basics. Validation checkpoints in the triage flow are implicit rather than explicit, which is the main gap.

Suggestions

Add an explicit validation checkpoint in the failure triage flow (e.g., 'Confirm the failure reproduces across two builds before classifying as code vs infrastructure').

Trim editorial phrasings like 'Things that have caused confusion before and will again' to keep every token earning its place.

Consider extracting the large CI-pipeline and pipeline-YAML file tables into a reference file so SKILL.md stays a leaner overview, improving progressive disclosure.

DimensionReasoningScore

Conciseness

Mostly lean and information-dense using tables and concrete file paths, assuming Claude knows basics; minor trimmable phrasings like 'Things that have caused confusion before and will again' and 'Common cause:' intros.

4 / 5

Actionability

Concrete file paths, a specific git command ('git log --oneline --since=\'3 days ago\''), and exact NativeAOT property values ('ILCompilerTargetsPath... with _IlcReferencedAsPackage=false'); mostly executable with minor gaps as guidance is path-reference heavy rather than copy-paste code blocks.

4 / 5

Workflow Clarity

Clear triage sequence — 'Classify every failure as infrastructure or code before acting' — with branch indicators and steps for each; checkpoints are implicit rather than explicit, but no destructive/batch operation requires a hard cap.

4 / 5

Progressive Disclosure

No bundle files exist; the single self-contained SKILL.md is well-organized into clear sections (Why mobile is different, CI pipeline, Where to look, Platform gotchas, Failure triage) with tables, giving good navigable structure despite the absence of external references.

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 excellent description: third person, concrete, with explicit 'Use when' trigger guidance and a clear, narrow niche. It names specific pipelines, file targets, and platform variants that a user would naturally reference.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'triaging and fixing .NET failures', 'failure triage (infrastructure vs code), CI pipeline structure, platform-specific code paths, and NativeAOT compilation' — with comprehensive coverage of the mobile domain.

5 / 5

Completeness

Explicitly answers both 'what' ('Domain knowledge for triaging and fixing .NET failures...') and 'when' ('Use when runtime-extra-platforms or mobile CI is failing...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Comprehensive natural keywords users would say: 'runtime-extra-platforms', 'mobile CI', 'iOS, tvOS, MacCatalyst, iossimulator, tvossimulator, Android', plus 'code signing', 'provisioning', 'simulator/emulator startup', 'NativeAOT-on-mobile'.

5 / 5

Distinctiveness Conflict Risk

Clear niche (mobile .NET on Apple/Android in dotnet/runtime) with distinct triggers naming specific pipelines, builders, and platform variants; minimal conflict risk with other skills.
