## What a skill does

A Lithi skill gives your agent task-specific instructions: which command to run, in what order, and what to check before moving on. Your agent loads a skill only when the current task matches it.

## When to reach for one

Use a skill for a repeated Lithi task your agent would otherwise reconstruct from scratch each time, such as requesting a quote with [`lithi.quote`](/docs/agent-resources/mcp), running an approved batch, or reading back a receipt.

## Installing a skill

Every skill installation is previewed before it applies. You see the exact configuration change, confirm it, and your agent only starts using the skill after that confirmation.

## Skills, MCP, and the CLI together

A skill tells your agent what to do. [MCP](/docs/agent-resources/mcp) is how it does paid work. The [CLI](/docs/agent-resources/cli) is how you check or reverse a change yourself.
