Quality
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 excels across all dimensions. It provides specific concrete actions, includes natural trigger terms users would actually use, explicitly states both what the skill does and when to use it, and carves out a distinct niche that won't conflict with other skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Create and manage Claude Code plugins', 'proper structure, manifests, and marketplace integration', 'adding plugin components (commands, agents, hooks)', 'bumping plugin versions', 'working with plugin.json/marketplace.json manifests'. | 3 / 3 |
Completeness | Clearly answers both what ('Create and manage Claude Code plugins with proper structure, manifests, and marketplace integration') AND when ('Use when creating plugins for a marketplace, adding plugin components, bumping plugin versions, or working with plugin.json/marketplace.json manifests'). | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'plugins', 'marketplace', 'commands', 'agents', 'hooks', 'plugin versions', 'plugin.json', 'marketplace.json', 'manifests'. Good coverage of domain-specific terms. | 3 / 3 |
Distinctiveness Conflict Risk | Very specific niche targeting Claude Code plugins with distinct triggers like 'plugin.json', 'marketplace.json', 'plugin components', and 'marketplace integration'. Unlikely to conflict with general coding or documentation skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
87%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, actionable skill that efficiently covers plugin creation and management. The content is appropriately concise with executable examples and good progressive disclosure to reference docs. The main weakness is the lack of explicit validation steps in workflows, particularly for manifest creation and version bumping where errors could cause issues.
Suggestions
Add validation checkpoint after plugin creation: e.g., 'Verify plugin.json is valid JSON and marketplace.json was updated correctly before proceeding'
Include a verification step in the local testing workflow to confirm the plugin installed correctly (e.g., check /plugin list output)
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Content is lean and efficient, providing direct commands and examples without explaining concepts Claude already knows. No unnecessary padding or verbose explanations of what plugins are. | 3 / 3 |
Actionability | Provides fully executable bash commands, complete JSON examples, and copy-paste ready code. Directory structures, manifest schemas, and testing commands are all concrete and specific. | 3 / 3 |
Workflow Clarity | Steps are clearly numbered and sequenced in the Development Workflow section, but lacks explicit validation checkpoints. No verification step after creating manifests or before publishing to catch errors. | 2 / 3 |
Progressive Disclosure | Well-organized with clear overview sections and explicit references to detailed docs (references/plugin-structure.md, references/marketplace-schema.md, references/workflows.md). One-level-deep navigation with clear signaling. | 3 / 3 |
Total | 11 / 12 Passed |
