86%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-structured, highly actionable skill body: executable examples in two languages, concrete commands, behavior-focused anti-patterns with WHY explanations, and a clean reference table pointing to a real, well-organized bundle. The minor gaps are boundary-section redundancy that could be trimmed and the absence of an error-recovery feedback loop in the workflow.
Suggestions
Consolidate 'When to Use', 'When Not to Use', and 'Scope' into a single compact section — they currently restate the same boundary information three times, and the frontmatter description already carries the triggers.
Add an explicit error-recovery branch to the workflow, e.g., 'If the failing test fails for the wrong reason, fix the test before implementing' — this closes the feedback loop needed for the top workflow-clarity anchor.
Consider replacing or augmenting the trivial add(2, 3) example with one that shows a behavior-first API decision, since the current example spends lines demonstrating something Claude already knows how to write.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is efficient with no tutorial-style explanation of concepts Claude already knows — every example is concrete code — but the 'When to Use', 'When Not to Use', and 'Scope In/Out' sections (~25 lines) largely restate boundary information already in the description, and the trivial add() example is trimmable. This matches the 'minor instances of over-explanation that could be trimmed' anchor rather than the 'noticeably verbose' or 'every token earns its place' anchors. | 4 / 5 |
Actionability | Fully executable TypeScript and Elixir examples covering the RED-GREEN-REFACTOR cycle, copy-paste-ready commands (bun test --watch, mix test), and BAD/GOOD code contrasts in every anti-pattern match the top anchor: 'copy-paste ready code or commands; specific examples cover the common cases'. | 5 / 5 |
Workflow Clarity | The 5-step workflow has a clear sequence and an explicit validation checkpoint ('Run tests and verify failure is for the expected reason') plus a green-suite guard on refactoring, matching the 'clear sequence with most checkpoints present' anchor. It falls short of the top anchor because there is no error-recovery feedback loop (e.g., what to do when RED fails for the wrong reason). | 4 / 5 |
Progressive Disclosure | Verified against the actual bundle: the body is a genuine navigation hub, six references are surfaced in a clearly-labeled topic table, all referenced paths resolve to real one-level-deep files in references/, and the remaining 37 bundle files stay out of context. This matches the 'clear overview with well-signaled one-level-deep references; easy navigation' anchor. | 5 / 5 |
