Quality

Content

0%Scale 1-3

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

This skill reads as a persona/role description rather than an actionable skill file. It consists almost entirely of exhaustive bullet-point lists cataloging Flutter concepts, libraries, and patterns that Claude already knows, with no executable code, no concrete workflows, and no practical examples. The content would need a fundamental restructuring to be useful—replacing the capability inventory with specific, actionable guidance for common Flutter tasks.

Suggestions

Replace the capability inventory with 2-3 concrete, executable code examples for the most common Flutter tasks (e.g., setting up a Riverpod provider, creating a platform channel, writing a widget test).

Add a clear multi-step workflow with validation checkpoints for at least one complex operation, such as setting up a new Flutter project with clean architecture or deploying to multiple platforms.

Move detailed reference material (library comparisons, architecture patterns, platform-specific details) into separate bundle files and reference them from a concise overview in SKILL.md.

Remove the 'Capabilities', 'Knowledge Base', and 'Behavioral Traits' sections entirely—these describe what Claude already knows rather than providing new, actionable instructions.

DimensionReasoningScore

Conciseness

Extremely verbose and padded with information Claude already knows. The massive lists of capabilities, tools, libraries, architecture patterns, and behavioral traits are essentially a resume/persona description rather than actionable instructions. Most of this content (e.g., explaining what Riverpod is, listing testing strategies, describing what platform channels are) wastes tokens on knowledge Claude already possesses.

1 / 3

Actionability

Contains zero executable code, no concrete commands, no specific examples, and no copy-paste ready snippets. The entire content is abstract descriptions and bullet-point lists of concepts. The 'Response Approach' section lists vague steps like 'Analyze requirements' without any concrete guidance on how to do so. Example interactions are just prompt suggestions, not worked examples.

1 / 3

Workflow Clarity

No clear multi-step workflow is defined. The 'Response Approach' section lists 8 numbered items but they are abstract directives ('Analyze requirements', 'Recommend state management') with no validation checkpoints, no error recovery, and no concrete sequencing. There are no feedback loops for any of the complex operations mentioned (deployment, testing, platform integration).

1 / 3

Progressive Disclosure

The content is a monolithic wall of bullet points with no meaningful structure for navigation. It references `resources/implementation-playbook.md` once but no bundle files are provided, making this a dead reference. All content is dumped inline with no separation of overview vs. detailed reference material. The massive capability lists should be in separate reference files.

Description

22%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.

This description reads more like a course title than a skill description. It lacks concrete actions, has no explicit trigger guidance ('Use when...'), and relies on vague terms like 'Master' and 'advanced' without specifying what the skill actually does. The Flutter/Dart domain anchoring provides some distinctiveness but is insufficient for reliable skill selection.

Suggestions

Replace the vague 'Master Flutter development' with specific actions like 'Creates Flutter apps, builds custom widgets, manages state with Provider/Riverpod, configures multi-platform builds for iOS, Android, and web'.

Add an explicit 'Use when...' clause such as 'Use when the user asks about Flutter, Dart, mobile app development, cross-platform apps, or widget layout'.

Remove the aspirational tone ('Master') and use third-person declarative voice describing concrete capabilities (e.g., 'Scaffolds Flutter projects, debugs platform-specific issues, implements navigation and routing').

DimensionReasoningScore

Specificity

The description uses vague language like 'Master Flutter development' and 'advanced widgets' without listing any concrete actions. There are no specific capabilities described—no verbs like 'create', 'build', 'debug', or 'deploy'.

1 / 3

Completeness

The description vaguely addresses 'what' (Flutter development) but has no 'when' clause or explicit trigger guidance. There is no 'Use when...' or equivalent, which per the rubric should cap completeness at 2, and the 'what' itself is too vague to merit even a 2.

1 / 3

Trigger Term Quality

It includes some relevant keywords like 'Flutter', 'Dart 3', 'widgets', and 'multi-platform deployment' that users might mention, but misses common variations like 'mobile app', 'iOS', 'Android', 'web app', 'cross-platform', or specific tasks like 'state management' or 'UI layout'.

2 / 3

Distinctiveness Conflict Risk

Mentioning 'Flutter' and 'Dart 3' provides some distinctiveness from generic coding skills, but 'advanced widgets' and 'multi-platform deployment' are broad enough to overlap with other mobile or cross-platform development skills.
