arn-spark-style-explore

This skill should be used when the user says "style explore", "arn style", "visual style", "explore styles", "UI style", "look and feel", "design direction", "pick a style", "choose colors", "theme the app", "visual direction", "style guide", or wants to explore and define the visual design direction for their project through guided conversation, producing a style brief document with implementable toolkit configuration.

77%Weight 40%Scale 1-3

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

A well-structured, highly actionable conversational workflow with clear sequencing and error-recovery loops. Its main weakness is verbosity from redundant restating of the visual-direction context and an Agent Invocation Guide that duplicates the step instructions.

Suggestions

Collapse the repeated visual-direction / creative-anchors enumeration into one canonical block (e.g., in Step 2) and reference it from Prerequisites and Step 1 instead of restating it each time.

Trim or remove the Agent Invocation Guide table, since its rows restate guidance already given in Steps 1-3; keep only rows that add new situations not covered earlier.

Consider moving the long situation/asset-handling tables (Step 1 and Step 3) into a reference file to reduce inline body length and improve progressive disclosure.

DimensionReasoningScore

Conciseness

The workflow is detailed and domain-specific rather than explaining basics Claude lacks, but it repeats the same visual-direction/creative-anchors enumeration across Prerequisites, Step 1, Step 2, and the Agent Invocation Guide, and the Invocation Guide largely restates Steps 1-3, so it could be tightened.

2 / 3

Actionability

Highly actionable: exact AskUserQuestion prompts with numbered options, situation-to-action tables, concrete file paths, agent dispatch instructions with model parameters, and copy-ready user-facing messages.

3 / 3

Workflow Clarity

Steps 1-5 are clearly sequenced with explicit validation/checkpoint gates ('Ready to write the style brief?', 'How would you like to proceed') plus an Error Handling section with feedback loops (unhelpful specialist -> retry with specifics; capture failure -> manual screenshot fallback).

3 / 3

Progressive Disclosure

The style-brief template is correctly externalized as a one-level-deep, clearly signaled reference, but the 282-line body keeps substantial inline content (repeated visual-direction blocks, multiple tables, a duplicative Agent Invocation Guide) that could be split out.

Description

90%Weight 40%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.

The description is a strong, trigger-rich 'Use when...' statement that clearly conveys both capability and activation conditions. It is slightly light on a comprehensive list of discrete concrete actions, keeping specificity at 2.

DimensionReasoningScore

Specificity

Names the domain (visual design direction) and concrete outputs ('producing a style brief document with implementable toolkit configuration', 'guided conversation'), but does not enumerate a broad list of multiple discrete actions the way the level-3 anchor does.

2 / 3

Completeness

Explicitly answers both what ('explore and define the visual design direction... producing a style brief document') and when ('This skill should be used when the user says...'), satisfying the explicit-trigger requirement.

3 / 3

Trigger Term Quality

Extensive natural trigger phrases a user would actually say ('style explore', 'look and feel', 'pick a style', 'choose colors', 'theme the app', 'style guide') with good coverage of common variations.

3 / 3

Distinctiveness Conflict Risk

The triggers ('arn style', 'style explore', 'theme the app', 'style guide') carve a clear niche around style-brief exploration that is unlikely to fire for unrelated skills; no inferred sibling overlap is scored per the judge guideline.
