Discovery
7%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 severely underdeveloped, functioning more as a label than a useful skill description. It lacks any concrete actions, meaningful trigger terms, or guidance on when to use the skill. The redundant trigger phrase and absence of natural user language make it unlikely to be selected appropriately.
Suggestions
Add specific actions the skill performs, e.g., 'Creates Mermaid Gantt charts for project timelines, task scheduling, and milestone tracking'
Include a 'Use when...' clause with natural trigger terms like 'gantt chart', 'project timeline', 'task schedule', 'milestone diagram', or 'project planning visualization'
Remove the redundant trigger term and expand to include variations users would naturally say, such as 'timeline', 'schedule', 'project phases', 'task dependencies'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description only names the tool type ('Mermaid Gantt Chart Generator') without describing any concrete actions. There are no verbs describing what the skill actually does - no 'creates', 'generates', 'schedules', or similar action words. | 1 / 3 |
Completeness | The description fails to answer 'what does this do' beyond naming itself, and provides no 'when should Claude use it' guidance. There is no 'Use when...' clause or equivalent explicit trigger guidance. | 1 / 3 |
Trigger Term Quality | The trigger terms are redundant (same phrase repeated twice) and overly specific. Missing natural variations users would say like 'gantt chart', 'project timeline', 'schedule diagram', 'mermaid diagram', or 'task timeline'. | 1 / 3 |
Distinctiveness Conflict Risk | The mention of 'Mermaid Gantt Chart' is somewhat specific and distinguishes it from general diagramming skills, but 'Visual Content skill category' is vague and could overlap with many other visualization skills. | 2 / 3 |
Total | 5 / 12 Passed |
Implementation
0%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill content is essentially an empty template with no actual instructional value. It contains only meta-descriptions of what the skill claims to do without providing any Mermaid Gantt chart syntax, examples, or actionable guidance. Claude already knows what Gantt charts are and how Mermaid works - this skill adds nothing useful.
Suggestions
Add actual Mermaid Gantt chart syntax with a complete, executable example (e.g., ```mermaid gantt title Project dateFormat YYYY-MM-DD section Phase1 Task1 :a1, 2024-01-01, 30d```)
Include specific Gantt chart configuration options: dateFormat patterns, section definitions, task dependencies, milestone syntax
Provide 2-3 concrete examples showing different use cases: simple timeline, project with dependencies, multi-section chart
Remove all boilerplate sections (Purpose, When to Use, Capabilities, Example Triggers) and replace with actionable reference content
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is padded with generic boilerplate that explains nothing Claude doesn't already know. Phrases like 'provides automated assistance' and 'follows industry best practices' are meaningless filler with no actual information about Mermaid Gantt charts. | 1 / 3 |
Actionability | There is zero concrete guidance - no Mermaid syntax, no code examples, no actual Gantt chart structure. The skill describes what it claims to do rather than providing any executable instructions. | 1 / 3 |
Workflow Clarity | No workflow is defined. There are no steps for creating a Gantt chart, no validation checkpoints, and no actual process to follow. The content is purely descriptive metadata. | 1 / 3 |
Progressive Disclosure | The content is a monolithic block of unhelpful boilerplate with no structure pointing to actual resources, examples, or detailed documentation. There's nothing to disclose progressively because there's no substantive content. | 1 / 3 |
