shadcn

Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI, including chat interfaces. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes, or any project with a components.json file. Also triggers for "shadcn init", "create an app with --preset", or "switch to --preset".

Content

88%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is highly actionable and well-sequenced with explicit validation checkpoints, and it organizes detail into well-signaled one-level-deep references. Its main weaknesses are mild repetition across sections and that the linked rule/reference files (rules/*.md, cli.md, registry.md, customization.md) are not present in the bundle, breaking the progressive-disclosure navigation it advertises.

Suggestions

Include the referenced rule and reference files (rules/*.md, cli.md, registry.md, customization.md) in the bundle, or remove the dead links — the body currently advertises navigation to files that do not exist.

Deduplicate preset-flag guidance between the Workflow (#9) and Quick Reference sections so each command appears in one canonical place.

Trim the component-selection table or move it into a reference file to reduce the inline token footprint, keeping only the most common mappings in SKILL.md.

Dimension	Reasoning	Score
Conciseness	The body is dense and largely assumes Claude's competence — rules are terse one-liners and code snippets are tight — but it still runs ~270 lines and repeats some guidance (e.g., preset sub-flags appear in both Workflow and Quick Reference), leaving minor trimming opportunities.	4 / 5
Actionability	Every rule is paired with concrete, executable commands (npx shadcn@latest … with specific flags) and copy-paste-ready code pairs showing correct vs. incorrect usage, fully covering the common cases.	5 / 5
Workflow Clarity	The numbered Workflow gives a clear sequence with explicit validation checkpoints — check installed components before add, run docs before using, use --dry-run/--diff to preview, read added files and verify correctness — including feedback loops for risky batch/registry operations.	5 / 5
Progressive Disclosure	Structure is strong: SKILL.md is an overview with one-level-deep, clearly signaled references (rules/*.md, cli.md, registry.md, customization.md) and a detailed-references index. However, the referenced bundle files do not exist on disk, so navigation links cannot be resolved — a real organizational gap rather than just an inlining issue.	4 / 5

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is exemplary: it states concrete capabilities, gives explicit "Applies when" and "Also triggers for" guidance with natural user phrases, and is tightly scoped to shadcn-specific tokens that minimize conflict risk. No vague fluff or over-claims.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — "adding, searching, fixing, debugging, styling, and composing UI" — alongside concrete project-context capabilities (component docs, usage examples), giving comprehensive coverage of the skill's actions.	5 / 5
Completeness	Explicitly answers both halves: the "what" (manages components/projects, provides context, docs, examples) and the "when" ("Applies when working with shadcn/ui…" plus the explicit "Also triggers for…" trigger phrases).	5 / 5
Trigger Term Quality	Covers natural terms users would say — "shadcn/ui", "components.json", "component registries", "presets", "--preset codes", "shadcn init", "create an app with --preset", "switch to --preset" — including the concrete file/flag tokens that trigger the skill.	5 / 5
Distinctiveness Conflict Risk	The niche is sharply defined by product-specific tokens (shadcn/ui, components.json, --preset), making collision with other skills minimal and the triggers highly distinctive.	5 / 5
