Discovery
0%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 is essentially a placeholder with no functional content. It fails on every dimension: it describes no concrete actions, includes no natural trigger terms, answers neither 'what' nor 'when', and provides no distinguishing characteristics that would help Claude select it appropriately.
Suggestions
Replace the placeholder text with concrete actions describing what the skill actually does (e.g., 'Generates sample data, creates mock API responses, scaffolds test fixtures').
Add an explicit 'Use when...' clause with natural trigger terms that describe the situations in which this skill should be selected.
Include domain-specific keywords and file types/formats to make the skill clearly distinguishable from others.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description contains no concrete actions whatsoever. 'Demo skill for the SkillToolProfile example' is entirely abstract and does not describe any capabilities. | 1 / 3 |
Completeness | Neither 'what does this do' nor 'when should Claude use it' is answered. There is no 'Use when...' clause and no description of functionality. | 1 / 3 |
Trigger Term Quality | There are no natural keywords a user would say. 'SkillToolProfile' is internal jargon, and 'demo skill' is not something a user would request. | 1 / 3 |
Distinctiveness Conflict Risk | The description is so generic and uninformative that it provides no distinguishing characteristics. It could not be reliably selected over any other skill. | 1 / 3 |
Total | 4 / 12 Passed |
Implementation
37%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a minimal demo skill that provides a single command but lacks meaningful workflow guidance, validation steps, and clear actionable instructions. It serves as a placeholder/demonstration rather than a genuinely useful skill, which limits its scores across most dimensions.
Suggestions
Add a brief description of what `scripts/write_profile.sh` does and what output to expect (e.g., expected file contents or success indicators).
If 'docs' are referenced for knowledge-only mode, provide explicit links or file paths to those docs.
Include a validation step after running the command (e.g., 'Verify output: `cat out/profile.txt` should contain...').
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is short but includes some unnecessary explanation ('This skill exists only to demonstrate...') and the 'knowledge-only mode' paragraph adds context that could be trimmed. However, it's not excessively verbose. | 2 / 3 |
Actionability | It provides one concrete command (`sh scripts/write_profile.sh out/profile.txt`), but lacks context on what the script does, what output to expect, or any further executable guidance. The 'knowledge-only mode' instruction is vague. | 2 / 3 |
Workflow Clarity | There is no clear workflow, no sequencing of steps, and no validation or verification of the command's output. The skill simply presents a single command with minimal context about when or how to use it. | 1 / 3 |
Progressive Disclosure | The skill is very short and doesn't need external references, but it mentions 'docs' for reasoning in knowledge-only mode without linking to them. The structure is minimal but adequate for its size. | 2 / 3 |
Total | 7 / 12 Passed |
