Discovery

89%

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-structured description for a very narrow skill. It clearly states what it does and when to use it, with distinctive trigger terms that minimize conflict risk. The only minor weakness is that the capability itself is singular and simple, so there isn't much to elaborate on in terms of specificity.

DimensionReasoningScore

Specificity

It names a specific action ('Display colorful ANSI art of the word "ultrathink"') but describes only a single, narrow action rather than listing multiple concrete capabilities.

2 / 3

Completeness

Clearly answers both 'what' (display colorful ANSI art of the word 'ultrathink') and 'when' (when the user says 'ultrathink' or invokes /ultrathink), with explicit trigger guidance.

3 / 3

Trigger Term Quality

Includes the natural trigger terms 'ultrathink' and '/ultrathink', which are exactly what a user would say to invoke this skill. Given the narrow scope, these are the right and sufficient keywords.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive — the trigger 'ultrathink' and '/ultrathink' are unique terms unlikely to conflict with any other skill. The niche is very clear and narrow.

Implementation

100%

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

This is an exemplary simple skill — maximally concise, fully actionable, and perfectly scoped. It provides an executable command with a clear behavioral constraint ('Do not add any other output or commentary'), and wastes zero tokens on explanation Claude doesn't need.

DimensionReasoningScore

Conciseness

Extremely lean — no unnecessary explanation, no padding. Every token serves a purpose. Claude doesn't need to be told what ANSI art is or how printf works.

3 / 3

Actionability

Provides a fully executable, copy-paste ready bash command. The instruction is completely unambiguous: run this command, output nothing else.

3 / 3

Workflow Clarity

This is a single-action skill with no multi-step process. The single action is completely unambiguous: run the command, no other output. Per scoring notes for simple skills, this merits a 3.

3 / 3

Progressive Disclosure

For a skill under 50 lines with no need for external references, the content is well-organized with a clear heading and a single well-structured section. No external files are needed.
