Discovery
40%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 niche (domain name generation and availability checking) with some useful trigger terms like specific TLDs. However, it lacks an explicit 'Use when...' clause, uses second person ('your project'), and includes filler marketing language ('Saves hours of brainstorming and manual checking') that doesn't aid skill selection.
Suggestions
Add an explicit 'Use when...' clause, e.g., 'Use when the user asks for domain name suggestions, wants to check domain availability, or mentions finding a website name.'
Replace the marketing fluff 'Saves hours of brainstorming and manual checking' with additional trigger terms like 'domain search', 'website name', 'register domain', or 'domain lookup'.
Switch from second person ('your project') to third person ('a project') to match the expected voice.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (domain names) and two actions (generates ideas, checks availability), but doesn't list more granular capabilities like filtering, ranking, or exporting results. The phrase 'Saves hours of brainstorming' is marketing fluff rather than a concrete action. | 2 / 3 |
Completeness | It describes what the skill does (generates domain names, checks availability) but has no explicit 'Use when...' clause or equivalent trigger guidance. Per the rubric, a missing 'Use when...' clause caps completeness at 2, and the 'when' is not even implied clearly enough to warrant a 2—it's only loosely implied through the description of capabilities. | 1 / 3 |
Trigger Term Quality | Includes relevant terms like 'domain name', 'TLDs', '.com', '.io', '.dev', '.ai', and 'availability', which users might naturally say. However, it misses common variations like 'domain search', 'register domain', 'buy domain', 'website name', or 'domain lookup'. | 2 / 3 |
Distinctiveness Conflict Risk | Domain name generation and TLD availability checking is a very specific niche. It's unlikely to conflict with other skills given the distinct focus on domain names, TLDs, and availability checking. | 3 / 3 |

Implementation
12%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is essentially a verbose prompt template with no actual mechanism for domain availability checking—the core value proposition. It spends most of its token budget explaining concepts Claude already knows (what makes a good domain name, what TLDs mean, general branding tips) rather than providing actionable tooling or concrete implementation. The fabricated example output showing availability status without any real checking capability is misleading.
Suggestions
Remove all general knowledge sections (TLD guide, naming tips, pricing context, 'When to Use') that Claude already knows, reducing the skill to essential instructions only.
Add concrete, executable code or tool usage for actually checking domain availability (e.g., using `whois` command, DNS lookups, or a specific API), since this is the core value proposition.
Move the example workflows, advanced features, and tips into a separate reference file, keeping SKILL.md as a concise overview with clear pointers.
Add validation steps: how to verify availability claims before presenting them to the user, and what to do when the checking mechanism fails or returns ambiguous results.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely verbose with extensive sections explaining obvious concepts (what makes a good domain, TLD guide, tips for success, pricing context) that Claude already knows. The 'When to Use This Skill' and 'What This Skill Does' sections are unnecessary padding. The content could be reduced by 70%+ without losing actionable value. | 1 / 3 |
Actionability | No executable code, no concrete commands, no actual mechanism for checking domain availability. The skill describes what outputs should look like but provides no tools, APIs, or scripts to actually check availability. The example output appears fabricated with no way to verify any of the availability claims. | 1 / 3 |
Workflow Clarity | The 'Example Workflows' section provides numbered steps for different scenarios, and the example output shows a clear sequence. However, there's no validation or verification mechanism—no way to actually confirm domain availability, and no feedback loops for when suggestions don't meet user needs. | 2 / 3 |
Progressive Disclosure | Monolithic wall of text with no references to external files. All content is inline including TLD guides, pricing context, naming tips, and multiple workflow examples that could be separated. The document is excessively long for a skill file with no progressive structure. | 1 / 3 |
Total | 5 / 12 Passed |
Validation
90%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
