Integrating shadcn/ui Components

What it does

When your agent uses it

• Adding a shadcn/ui component to a React project
• Setting up shadcn/ui in a new or existing project
• Customizing a component or switching between Radix UI and Base UI
• Working with a custom component registry

Example prompts

• “Add the dialog and data table components from shadcn/ui to this project.”
• “Set up shadcn/ui in my existing app and verify the setup.”
• “Build a login page layout with shadcn/ui form components.”

Requirements

• npx, to run the shadcn command line tool
• The shadcn MCP server, for component discovery
• Pre-approved tools (allowed-tools): shadcn*:*, mcp_shadcn*, Read, Write, Bash, web_fetch

Workflow steps

What it can do on your machine

Read from SKILL.md and the folder at commit 0337446. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • shadcn*:*
  • mcp_shadcn*
  • Read
  • Write
  • Bash
  • web_fetch

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 1 file in scripts/ (Shell), which the agent can run.

  Shell commands in SKILL.md call:

  • npx
  • tsc

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Integrating shadcn/ui Components loads about 2.3k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 762 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~44

When it runs · the whole SKILL.md, loaded when a task matches

~2.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

• NotePre-approves every shell command (allowed-tools: Bash)SKILL.md

  allowed-tools: shadcn*:*, mcp_shadcn*, Read, Write, Bash, web_fetch

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
