Quality

Content

20%

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 monolithic enumeration of Flutter expertise that restates what Claude already knows and offers almost no executable guidance, with only a generic workflow sequence and a dangling reference to a missing playbook. Conciseness and actionability are the dominant weaknesses.

Suggestions

Cut the restated-domain padding — especially "Behavioral Traits", "Knowledge Base", and the exhaustive library/pattern lists — and keep only skill-specific guidance Claude would not already produce on its own.

Add concrete, executable artifacts: real Dart/Flutter code snippets, exact commands, or copy-paste templates for the most common tasks instead of abstract bullet descriptions.

Fix the dangling reference by either creating `resources/implementation-playbook.md` (under a real bundle path) or removing the pointer, and move the large capability enumerations into that referenced file for genuine progressive disclosure.

DimensionReasoningScore

Conciseness

The ~195-line body restates domain knowledge Claude already knows (every state-management library, architecture pattern, and platform integration) plus padded "Behavioral Traits" and "Knowledge Base" sections, matching the verbose/padded score-1 anchor rather than the lean score-3 anchor.

1 / 3

Actionability

There is no executable code or concrete command anywhere; guidance is abstract description ("Prioritizes widget composition over inheritance", "Implements const constructors") and the example interactions are prompts rather than solutions, fitting the describes-rather-than-instructs score-1 anchor.

1 / 3

Workflow Clarity

The numbered "Response Approach" and "Instructions" provide a sequence and generically mention "validate outcomes" and "verification", but there are no concrete validation checkpoints for risky deployment/security operations, so it stays at the score-2 cap rather than the score-3 explicit-checkpoint anchor.

2 / 3

Progressive Disclosure

Headers provide some structure, but the large capability/knowledge enumerations that should live in separate files are inline, and the lone reference "open `resources/implementation-playback.md`" points to a file that does not exist, fitting the score-2 anchor rather than a clean one-level-deep reference structure.

Description

50%

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 identifies a clear domain (Flutter/Dart 3) but reads as a learning tagline rather than a trigger-rich skill description, with no explicit "Use when…" clause. Specificity, triggers, completeness, and distinctiveness all land at the middle anchor as a result.

Suggestions

Rewrite in third person with concrete skill actions, e.g. "Builds, optimizes, and deploys multi-platform Flutter apps with Dart 3, advanced widget composition, and platform-specific integrations." to lift specificity and fix the imperative "Master" voice.

Add an explicit trigger clause: "Use when building, debugging, or deploying Flutter apps, or when the user mentions Flutter, Dart, widgets, or cross-platform mobile/web/desktop apps." to raise completeness and trigger_term_quality.

Include common user-facing phrasings ("Flutter app", "build/deploy Flutter", "iOS/Android", "cross-platform") to improve trigger coverage and distinctiveness.

DimensionReasoningScore

Specificity

Quotes "Master Flutter development with Dart 3, advanced widgets, and multi-platform deployment" name the domain and several capability areas, but the goal-verb "Master" is abstract rather than a list of concrete skill actions like the score-3 anchor.

2 / 3

Completeness

The description answers "what" but contains no explicit "Use when…" trigger clause, so per the judging guidelines completeness is capped at 2 rather than reaching the score-3 both-what-and-when anchor.

2 / 3

Trigger Term Quality

"Flutter development" and "Dart 3" are natural user terms, but common variations a user would actually say ("Flutter app", "build/deploy Flutter", "iOS/Android", "cross-platform") are missing, matching the score-2 anchor.

2 / 3

Distinctiveness Conflict Risk

Flutter is a genuine niche, but the broad "development" scope combined with the absence of explicit triggers means it could still overlap with adjacent Dart or cross-platform skills, fitting the score-2 anchor.
