Discovery

100%

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 is a well-crafted skill description that follows best practices. It uses third person voice, provides specific capabilities (compression formats, automatic tool selection), and includes an explicit 'Use when' clause with natural trigger terms users would actually say. The description is concise yet comprehensive.

DimensionReasoningScore

Specificity

Lists specific concrete actions: 'Compresses images to WebP (default) or PNG with automatic tool selection' - describes the compression formats and mentions automatic tool selection as a feature.

3 / 3

Completeness

Clearly answers both what (compresses images to WebP/PNG with automatic tool selection) and when (explicit 'Use when' clause with multiple trigger scenarios).

3 / 3

Trigger Term Quality

Excellent coverage of natural user terms: 'compress image', 'optimize image', 'convert to webp', 'reduce image file size' - these are exactly what users would naturally say when needing this functionality.

3 / 3

Distinctiveness Conflict Risk

Clear niche focused specifically on image compression/optimization with distinct format mentions (WebP, PNG) and specific trigger terms that wouldn't overlap with general image editing or other document processing skills.

Implementation

88%

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

This is a well-structured, concise skill for an image compression CLI tool. It excels at actionability with executable examples and clear option documentation. The EXTEND.md preference system is documented but could benefit from explicit validation/error handling guidance for the configuration loading workflow.

DimensionReasoningScore

Conciseness

Content is lean and efficient with no unnecessary explanations. Tables and examples are compact, and Claude's intelligence is respected throughout.

3 / 3

Actionability

Provides fully executable commands with clear options table, concrete examples covering multiple use cases, and expected output format. All commands are copy-paste ready.

3 / 3

Workflow Clarity

The skill documents a single-command tool well, but the EXTEND.md preference checking workflow lacks explicit validation steps. The bash check is provided but there's no guidance on what to do if parsing fails or settings are invalid.

2 / 3

Progressive Disclosure

Well-organized with clear sections (Script Directory, Preferences, Usage, Options, Examples). References to EXTEND.md are clearly signaled with paths and supported options noted. Appropriate length for a CLI tool skill.
