5 agent skills
Agent skills
frontend-design
Production-grade frontend that avoids the generic AI aesthetic.
Anthropic's first-party skill for distinctive interface work: creative, polished code rather than the default purple gradient.

canvas-design
Original visual design on a canvas: form, space, colour.
For posters, graphics and compositions rather than product screens. Design philosophy first, output second.

webapp-testing
Drives a local web app with Playwright.
Lets the agent open your dev server, click through it, screenshot what it sees and read the browser console. The gap it closes is an agent that writes frontend code it has never actually run.

skill-creator
Writes, edits and evaluates skills.
The first-party skill for making skills. It covers writing one from scratch, improving an existing one, running evals against it and tuning the description so the agent actually loads it at the right moment.

SystemsFull page & trust audit →mcp-builder
Builds MCP servers that are worth connecting.
Covers designing the tools rather than just exposing an API, in Python with FastMCP or in TypeScript with the MCP SDK. Most of the value is in the part about what makes a tool legible to a model.
