Quality

Content

85%

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

The body is a well-structured, highly actionable production guide with clear sequenced workflows, explicit validation gates, and a sound one-level-deep reference structure; its main weakness is conciseness, with redundancy and a large inline footprint despite external references.

Suggestions

Deduplicate content repeated across sections (design tokens in §3 vs Phase 0; staged rollout in §7 vs Phase 4) by cross-referencing instead of restating.

Move the full Phase 0–5 roadmap checklist detail into a reference file, keeping only phase summaries and exit criteria inline in SKILL.md.

Tighten tutorial-style framing sentences ('Every production Android project must separate...') into imperative rules.

DimensionReasoningScore

Conciseness

Largely dense, high-signal prescriptive rules that assume competence, but the 525-line body has redundancy (design tokens in §3 and Phase 0; staged rollout in §7 and Phase 4) and some tutorial-style framing that could be tightened.

2 / 3

Actionability

Provides concrete, specific guidance throughout — exact libraries, dp/fps targets, build variants, CI timings, and named tools — with real Kotlin/Gradle code blocks; the actionable specificity dominates even where code is illustrative pattern.

3 / 3

Workflow Clarity

Multi-step processes are clearly sequenced with explicit validation gates and checklists (7-step debugging process, phased CI/CD pipeline with timings, 5-phase roadmap, 'crash-free rate ≥ 99.5% on staging', device-farm runs before release).

3 / 3

Progressive Disclosure

Clear overview with a 'When to Use' map and an 'Additional Resources' section pointing to six real, one-level-deep reference files (verified to exist in references/), each signaled per stack in §1 with easy navigation.

Description

57%

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

The description conveys a clear, specific scope around Android and cross-platform app development with distinct stack naming, but it lacks explicit invocation triggers and frames coverage rather than concrete actions.

Suggestions

Add a 'Use when...' clause with explicit triggers (e.g., 'Use when building, architecting, testing, or releasing Android or cross-platform (non-iOS) apps').

Reframe coverage areas as concrete actions the skill performs (e.g., 'guide architecture, UI design, testing, and release') rather than listing what it 'covers'.

Add common natural trigger terms users would say ('build an Android app', 'Kotlin app', 'Compose', 'cross-platform app').

DimensionReasoningScore

Specificity

Names the domain and enumerates concrete stacks ('native (Kotlin/Java), cross-platform (Flutter, RN, KMM), and hybrid architectures') but describes coverage areas rather than concrete actions the skill performs.

2 / 3

Completeness

Clearly states what the skill covers but omits any 'Use when...' trigger guidance for when to invoke it, which caps completeness at 2 per the rubric guideline.

2 / 3

Trigger Term Quality

Includes natural terms like 'Android app development', 'native', 'Flutter', 'RN', 'KMM' that users would say, but misses common variations such as 'build an Android app', 'Kotlin', 'Compose', or 'cross-platform'.

2 / 3

Distinctiveness Conflict Risk

Scoped specifically to Android and named cross-platform/hybrid stacks, giving it a clear niche unlikely to trigger for unrelated skills.
