78%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 overview skill that leans on a real, verified bundle of one-level-deep references and provides a concrete workflow plus output checklist. Main weaknesses are mild redundancy between the Principles and Critical usage rules sections and the lack of an explicit error-recovery feedback loop.
Suggestions
Consolidate overlapping guidance between the 'Principles for agent output' and 'Critical usage rules' sections to remove redundancy (e.g., 'use existing primitives first' vs 'do not invent coss APIs').
Add an explicit validate→fix→retry feedback loop in the Usage workflow (e.g., 'if the self-check fails, revise imports/composition and re-check before returning code').
Merge the 'Component discovery' and 'Primitive Guidance' sections, which both restate that every primitive has a guide at ./references/primitives/<name>.md and point to the component registry.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence, avoiding concept explanations, but the Principles and Critical usage rules sections overlap ('Use existing primitives first' vs 'Do not invent coss APIs') and component-discovery guidance is restated in the Primitive Guidance section. | 4 / 5 |
Actionability | Provides concrete executable guidance — 'npx shadcn@latest add @coss/<component>', specific particle file paths 'p-<name>-<N>.tsx', and explicit reference paths — though most copy-paste code lives in the referenced files rather than inline. | 4 / 5 |
Workflow Clarity | A clear numbered 6-step Usage workflow and an Output Checklist provide a well-sequenced process with a self-check checkpoint, but there is no explicit validate→fix→retry feedback loop for error recovery. | 4 / 5 |
Progressive Disclosure | SKILL.md is a well-organized overview with clearly signaled one-level-deep references (./references/primitives/*.md, ./references/rules/*.md, component-registry, cli, portal-props), all of which exist as real files, making navigation easy. | 5 / 5 |
