Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI. 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".

Security
1 critical severity finding. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Several URLs point to user-controlled or third-party hosts (acme.com, private.com, api.npoint.io) and raw GitHub content — sources that can serve arbitrary code/JSON and are explicitly shown in the skill as examples where the CLI warns against manual raw fetches, so they could be used to distribute malicious component files if untrusted.
Low
Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Yes—required workflow includes fetching component documentation/examples and “fetch the URLs to get the actual content” (public web/registry content), which can include outsider-authored free text that the agent then reads and uses in prompts (SKILL.md workflow steps 4 and 7 plus CLI docs describing fetching examples from URLs).
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
The skill explicitly instructs fetching remote component docs/examples at runtime (e.g., https://raw.githubusercontent.com/.../examples/input-example.tsx, https://api.npoint.io/abc123, https://ui.shadcn.com/r/registries.json), which would inject externally-hosted source/instructions into the agent's context and thus directly influence its behavior.
