# Skills

> Reusable logic packages that extend what Lyzr agents can do.

Skills are modular, reusable building blocks that define what an agent can do. Unlike tools (which call external APIs), skills contain executable logic: code, multi-step prompts, or tool integrations packaged as a single reusable unit.

## Why skills exist

Without skills, every agent you build needs the same logic written again: the same email formatting, the same data transformation, the same API integration pattern. Skills let you write logic once and attach it to any agent.

## Skills vs. tools

|            | Skills                                          | Tools                                |
| ---------- | ----------------------------------------------- | ------------------------------------ |
| Contains   | Executable code + prompts                       | API integration spec                 |
| Reused how | Added to agent in Studio or via GitHub / zip    | Selected from the tools library      |
| Best for   | Multi-step logic, workflows, custom code        | Single-action external service calls |
| Format     | `SKILL.md` + code files in a zip or GitHub repo | JSON schema / OpenAPI spec           |

## Skill format

A skill is a directory (zip file or GitHub repo) with a `SKILL.md` file at its root. The `SKILL.md` defines the skill's interface, parameters, and behavior.
