This is a concise, well-scoped meta-skill that establishes clear anti-patterns for SKILL.md authoring. Its main strength is extreme token efficiency and non-obvious constraints about avoiding tool/parameter name duplication. Its weakness is the lack of a concrete positive example showing what a good SKILL.md looks like under these principles, and the absence of a sequenced authoring workflow.
Suggestions
Add a brief positive example (5-10 lines) showing a well-written SKILL.md snippet that follows these principles, contrasted with a bad example that violates them.
Consider adding a minimal authoring checklist (3-4 steps) to sequence the writing process, e.g., 'identify tool group → write prose descriptions → verify no tool/param names → test against live MCP schema'.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Every sentence carries unique, non-obvious information. No padding, no explanation of concepts Claude already knows. The skill is lean and each bullet earns its place by conveying a specific, non-trivial constraint. | 3 / 3 |
Actionability | The guidance is specific about what NOT to do (don't duplicate params, don't name tools/params) and provides concrete prose-style alternatives, but it lacks a positive example of a well-written SKILL.md snippet or a before/after comparison that would make the guidance fully concrete and copy-paste actionable. | 2 / 3 |
Workflow Clarity | The skill lists principles but doesn't sequence them into a workflow for authoring a SKILL.md. For a skill about writing other skills, a brief step-by-step process (e.g., 1. identify MCP tool group, 2. write prose descriptions, 3. verify no tool/param names leaked) with a validation checkpoint would improve clarity. However, the single-purpose nature partially mitigates this. | 2 / 3 |
Progressive Disclosure | For a short, single-purpose skill under 50 lines with no need for external references, the content is well-organized with a clear heading and concise bullet list. No bundle files are needed and none are referenced, which is appropriate. | 3 / 3 |
