Quality
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 with strong trigger terms, explicit 'Use when' and 'Triggers on' clauses, and a clearly defined niche. Its main weakness is that the specific actions could be more concrete—listing what files are created, what validations are performed, or what the checklist entails would improve specificity.
Suggestions
Add more concrete action details, e.g., 'Creates plugin.json with required metadata fields, updates marketplace.json registry, generates README from template, validates plugin structure against schema.'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description mentions 'creating, adding, or modifying plugins' and 'ensures all required files are updated correctly,' but doesn't list the specific concrete actions (e.g., what files are created, what fields are populated, what validation is performed). The actions remain at a moderate level of detail. | 2 / 3 |
Completeness | Clearly answers both 'what' (creating, adding, modifying plugins, ensuring required files are updated) and 'when' (explicit 'Use when' clause and 'Triggers on' with specific trigger terms). Both components are explicitly stated. | 3 / 3 |
Trigger Term Quality | Excellent trigger term coverage including natural phrases ('create plugin', 'add plugin', 'new plugin', 'plugin checklist', 'marketplace') and specific file/directory references (plugin.json, marketplace.json, plugins/ directory). These are terms users would naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with a clear niche: it's scoped to a specific repository ('Glean Claude Plugins marketplace repository') and specific file types (plugin.json, marketplace.json, plugins/ directory). Very unlikely to conflict with other skills. | 3 / 3 |
Total | 11 / 12 Passed |
Implementation
77%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong, actionable checklist skill with excellent workflow clarity and concrete, executable guidance. Its main weaknesses are minor verbosity (meta-description, some redundancy between the checklist and 'Common Mistakes' section) and the monolithic structure that could benefit from splitting verification/version management into separate referenced files. The referenced script (check-bumper.mjs) is not included in the bundle, which is a minor gap.
Suggestions
Remove the opening meta-description sentence ('This skill provides the checklist...') — the heading and content make the purpose self-evident.
Consider consolidating 'Common Mistakes to Avoid' into inline warnings within the relevant checklist steps to reduce redundancy.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The opening sentence 'This skill provides the checklist for correctly adding or modifying plugins' is unnecessary meta-description. The 'Common Mistakes to Avoid' section partially duplicates information already covered in the checklist steps. However, most content is specific and non-obvious project configuration details that Claude wouldn't inherently know. | 2 / 3 |
Actionability | Provides fully executable bash commands, complete JSON templates with placeholders, exact file paths, and specific markdown snippets to add. Every step is copy-paste ready with concrete examples rather than abstract descriptions. | 3 / 3 |
Workflow Clarity | Steps are clearly numbered and sequenced with explicit validation commands at the end. The checklist format with REQUIRED labels, a dedicated verification section with runnable commands, and a feedback mechanism (check-bumper.mjs script) provides strong error recovery. The warning about silent failures in step 6 is an excellent validation checkpoint. | 3 / 3 |
Progressive Disclosure | The content is well-structured with clear sections and headers, but it's a fairly long monolithic document (~150 lines of substantive content). The verification commands, version management, and common mistakes sections could potentially be split into referenced files. However, no bundle files are provided, and the skill references a script (check-bumper.mjs) without bundling it. | 2 / 3 |
Total | 10 / 12 Passed |
