75%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-crafted, self-contained instruction skill: concrete templates, a numbered update workflow with a read-before-write safeguard, and disciplined length guidance. The gaps are minor — an explicit output-verification step, the escaped code-fence artifact, and an HTML template that inflates the always-loaded context.
Suggestions
Add an explicit validation step to the update rules (e.g. re-render check: confirm the Mermaid source parses and UML.html opens with diagrams visible) to close the workflow checkpoint gap.
Move the UML.html template into an assets/ file referenced from SKILL.md, or trim the CSS/placeholder comments, to cut always-loaded tokens.
Fix the escaped closing fence ('` `') in the markdown structure example so the template is valid markdown when copied verbatim.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is efficient — terse numbered rules ('Read before write', 'Mermaid only', 'Aim for < 200 lines') and templates with no concept over-explanation. Minor over-length in the HTML boilerplate's CSS and placeholder comments keeps it below anchor 5. | 4 / 5 |
Actionability | Provides a copy-paste-ready markdown structure template and a complete, executable HTML viewer template with a specific CDN import ('mermaid@11/dist/mermaid.esm.min.mjs'). The escaped fence '` ``' inside the mermaid example is a small wart that would need fixing on copy, and there are no runnable verification commands, so it falls just short of anchor 5. | 4 / 5 |
Workflow Clarity | Update rules are a clear numbered sequence with a safety checkpoint ('Always read the current UML.md... so you preserve hand-edited notes') plus a 'When to create it' section. Verification is only implied ('must open correctly with `open UML.html`') rather than an explicit validate step, matching anchor 4's 'most checkpoints present'. | 4 / 5 |
Progressive Disclosure | A single self-contained file with well-organized sections (file structure, HTML viewer, update rules, creation) and no nested or buried references. The ~60-line inline HTML template could arguably live in an assets/ file, but since it is needed on every invocation (both files are written together), inline placement is defensible — good structure with minor organization gaps. | 4 / 5 |
