What it does

Design Md is an agent skill from bifrost-proxy/bifrost. Use when changing Bifrost WebUI, desktop shell UI, public site, docs visual style, interaction patterns, layout, copy density, colors, typography, spacing, or component styling. Reads DESIGN.md as the product design contract and validates it with @google/design.md.

Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Design tokens. The repository describes itself as: Bifrost 是一个用 Rust 编写的高性能、AI 友好的代理服务器，它提供强大的请求拦截、修改和规则配置能力，支持 TLS 解密、脚本扩展等高级功能，支持强大的模糊搜索，支持导入导出分享，支持一键重放请求，支持Coding Agent 自主管理。提供类似 postman 的请求管理和验证能力，无缝和代理能力集成。 The licence is MIT.

When your agent uses it

  • Changing Bifrost WebUI
  • Desktop shell UI
  • Docs visual style
  • Interaction patterns

Example prompts

  • “/design-md”

Workflow steps

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

  1. Read DESIGN.md from the repository root.
  2. For process and verification details, read design/design-md-system.md.
  3. If the change touches site deployment, also follow the root AGENTS.md site deployment boundary.

What it can do on your machine

Read from SKILL.md and the folder at commit cad75f8. 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

Design Md loads about 544 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 253 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~544

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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
Use when changing Bifrost WebUI, desktop shell UI, public site, docs visual style, interaction patterns, layout, copy density, colors, typography, spacing, or component styling. Reads DESIGN.md as the product design contract and validates it with @google/design.md.

Bifrost DESIGN.md

This skill keeps Bifrost product interaction work consistent across agents and sessions.

When to Use

Use this skill before modifying:

  • web/ UI, layout, theme, navigation, dashboards, tables, modals, panels, or interaction copy
  • desktop/ shell UI and desktop-specific chrome
  • site/, docs/, or docs-en/ visual style, homepage, navigation, screenshots, or docs theme
  • any user-facing feature where color, density, component choice, spacing, typography, or visual hierarchy could drift

Required Reading

  1. Read DESIGN.md from the repository root.
  2. For process and verification details, read design/design-md-system.md.
  3. If the change touches site deployment, also follow the root AGENTS.md site deployment boundary.

Working Rules

  • Treat DESIGN.md YAML front matter as the normative design-token source.
  • Treat the Markdown sections as rationale for how to apply those tokens.
  • Prefer existing Ant Design tokens in web/ and the existing CSS variables in site/home/styles.css.
  • Keep operational UI dense, stable, and scan-friendly. Do not turn WebUI screens into marketing layouts.
  • Preserve light/dark parity. If a new color is needed in WebUI, route it through Ant Design token usage, CSS variables, or a documented DESIGN.md token.
  • Use icons for tool actions when an established icon exists; use text buttons only for clear commands.
  • Keep card usage restrained: repeated items, modals, and genuinely framed tools.
  • When editing DESIGN.md, run pnpm design:lint.

Verification

For design-token or design-rule changes:

bash
pnpm design:lint

For UI implementation changes, add the normal module tests plus human_tests coverage required by the repository. At minimum, verify light and dark theme behavior for WebUI changes and record the result in the relevant human_tests/ document.
