Panda CSS

What it does

When your agent uses it

• Editing TS/TSX styles imported from @bangumi/styled-system
• Converting Less
• CSS Modules to Panda CSS
• Adding responsive

Example prompts

• “/panda-css”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

1. 1Read AGENTS.md, panda.config.ts, the target component, and adjacent components before editing.
2. 2Read references/project-patterns.md for repository-specific
3. 3Inspect package.json and pnpm-lock.yaml for the installed Panda version. Treat the checked-in
4. 4When library behavior or API details matter, follow AGENTS.md and query current official Panda

What it can do on your machine

Read from SKILL.md and the folder at commit a0ad2aa. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • pnpm

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

• Network

  No URLs in SKILL.md. Its commands use pnpm, 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

Panda CSS loads about 1.4k tokens when it runs, and up to ~3.2k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 620 words of instructions outside code blocks.

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

~100

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

~1.4k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~3.2k

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

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); files beside SKILL.md are not scanned.

description

Implement, migrate, review, or debug Panda CSS styles in the Bangumi frontend. Use when editing TS/TSX styles imported from `@bangumi/styled-system`, converting Less or CSS Modules to Panda CSS, adding responsive or conditional styles, modeling component variants, changing `panda.config.ts` or PostCSS integration, regenerating `packages/styled-system`, or diagnosing missing Panda styles.

import { css, cx } from '@bangumi/styled-system/css';

const item = css({
  display: 'flex',
  alignItems: 'center',
  gap: '8px',
  _hover: { color: '#3db3f5' },
  smDown: { gap: '4px' },
});

const selected = css({ fontWeight: '600' });

<div className={cx(item, isSelected && selected)} />;
