Agent Skill

An agent skill is packaged, reusable expertise an AI assistant loads for a specific job, accessibility audit, PRD draft, Figma handoff, without the user rewriting instructions each time.

Skills combine prompts, steps, guardrails, and output format into a discoverable unit teams install, version, and invoke from the composer or slash commands.

What it means

A skill defines when to activate, what context to gather, how to execute, and what “done” looks like; the agent reads it at runtime (often from a SKILL.md file).

Why designers should care

Skills turn tribal prompt knowledge into durable workflow assets. Designers should own or co-own skills for critique, research synthesis, and design-system compliance.

Example

A UX team publishes a Usability Testing skill; invoking /usability-test in Cursor loads interview guides, synthesis schema, and report template in one run.

Common mistakes

  • Skills so generic they behave like a short system prompt with no steps.
  • No discovery path. Users must know the exact slash command.
  • Skills duplicated across repos with no shared library or version.
