Definition of an AI agent skill

An AI agent skill is a reusable, structured procedure that defines how an AI agent uses tools and integrations (such as MCP connectors and APIs) to reliably complete a specific task.

A skill is not just knowledge. A skill is step-by-step execution logic.

The chef, tools, and recipe model

A simple way to understand AI agent skills:

• AI agent = the chef → decides what to do
• MCP & integrations = the kitchen tools → enable action
• Skills = the recipes + how to use the tools → define execution

In Anima-style design-to-code workflows, the agent decides how to build the UI, MCP connectors provide access to Figma and IDEs, and skills define the exact build procedure.

No recipe → inconsistent results. No tools → no execution. No chef → no orchestration.

Why AI agent skills matter

Large language models can reason and generate. But production AI agents must also execute reliably. Skills provide structure for repeatable outcomes.

• Repeatability: The same task produces consistent output (component structure, layout logic, code patterns).
• Correct tool usage: Skills encode which MCP connector to call, what parameters to send, and what output to expect.
• Multi-step workflows: Skills support ordered execution across systems (Design → Parse → Map → Generate → Validate → Export).
• Guardrails and governance: Skills can enforce design systems, brand tokens, semantic HTML, and accessibility constraints.

Skill vs tool vs prompt (common confusion)

This is one of the most common AI agent questions. Here’s the clean separation:

Core components of an AI agent skill

A well-designed skill typically includes:

Goal

The outcome the skill produces (e.g., generate production-ready UI from a design).

Trigger

When the skill should activate (e.g., a Figma link or screen set is provided).

Step sequence

Ordered execution logic (e.g., import → parse → map → generate → validate).

Tool & MCP usage

Explicit connectors and systems used (e.g., Figma connector, code generator, MCP → IDE bridge).

Output contract

Defined output format (e.g., semantic HTML, React components, deployable project structure).

Guardrails

Constraints and checks (e.g., must use design tokens, must be responsive, must pass accessibility checks).

What makes an AI agent skills’ strength?

• Specific: one clear outcome per skill
• Step-based: ordered actions, not vague intent
• Tool-aware: explicit MCP and API usage
• Guardrailed: constraints and validation included
• Reusable: works across similar tasks
• Observable: outputs can be inspected and tested

Skill in a nutshell

An AI agent skill is a reusable, structured execution procedure that tells an AI agent how to use tools, MCP connectors, and APIs to complete a specific task with reliable, repeatable results.
