Slingshot brand kit
Slingshot's own brand, built as an agentic brand system: the same parts the company builds for others, used on itself first. It is the brand behind slingshot.fyi.
| Part | What it is |
|---|
| Kit | brand/: a router (readme.md) and five guides (voice, layout, typography, colour, mark). Every rule carries its reason, so a person or an agent can apply it to a case nobody wrote down. |
| Tokens | brand/tokens.json holds every value once; dist/tokens.css is generated from it. |
| CLI | slingshot-brand prints the guides and tokens, and checks files for colours that are not brand tokens. |
| MCP | slingshot-brand-mcp gives any MCP client (Claude Code, Claude Desktop, Cursor) the guides, the tokens and the colour check while it works. |
Use it
npx -p @slingshot-fyi/brand-kit slingshot-brand guide
npx -p @slingshot-fyi/brand-kit slingshot-brand guide voice
npx -p @slingshot-fyi/brand-kit slingshot-brand tokens
npx -p @slingshot-fyi/brand-kit slingshot-brand check src/*.css
In a clone of this repository, run npm install once and the same commands work as npx slingshot-brand ….
Add the MCP server to Claude Code:
claude mcp add slingshot-brand -- npx -y @slingshot-fyi/brand-kit
It exposes three tools: brand_guide, brand_tokens and check_colors.
How it is tested
npm test checks that every rule has a reason, that the generated CSS covers every token, that the colour check names brand colours and flags the rest, and starts the MCP server to call each tool over stdio.
The kit itself is tested the way Slingshot tests every kit: hand it to a fresh agent with no other context, ask it to make something new, and treat every guess it makes as a missing rule.
