What it does

Fast Agent Design is an agent skill from evalstate/fast-agent. Use this skill to generate well-branded interfaces and assets for fast-agent, either for production or throwaway prototypes/mocks/etc. Contains essential design guidelines, colors, type, fonts, assets, and UI kit components for protoyping.

Its SKILL.md is about 220 tokens, which your agent loads only when the skill is triggered. The skill folder holds 177 other files, including assets (for example `CHARACTER-DIRECTION.md`, `_adherence.oxlintrc.json` and `_ds_bundle.js`).

It sits in Frontend & Design, covering Prototyping, Design systems and MCP servers. It works with Model Context Protocol and Python. The repository describes itself as: Code, Build and Evaluate agents - excellent Model and Skills/MCP/ACP/A2A Support. The licence is Apache-2.0.

When your agent uses it

  • Generate well-branded interfaces and assets for fast-agent
  • Either for production
  • Throwaway prototypes/mocks/etc

Example prompts

  • “/fast-agent-design”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit e8fd010. 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

    Ships script files (JavaScript, from the files we listed), which the agent can run.

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

  • Network

    No URLs in SKILL.md.

    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

Fast Agent Design loads about 220 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 97 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~220

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.

user-invocable
true

Read the readme.md file within this skill, and explore the other available files. If creating visual artifacts (slides, mocks, throwaway prototypes, etc), copy assets out and create static HTML files for the user to view. If working on production code, you can copy assets and read the rules here to become an expert in designing with this brand. If the user invokes this skill without any other guidance, ask them what they want to build or design, ask some questions, and act as an expert designer who outputs HTML artifacts or production code, depending on the need.
