## About

# Echo Skill

The simplest possible skill — it echoes the user's wish back as the result.

## When to use

Use this skill when the user wish is:

- A greeting: "hi", "hello", "hey there"
- A literal echo request: "echo hello world", "say something"
- A smoke test: "is this working?"
- Anything purely conversational that doesn't need data, fetching, or analysis

## How to respond

No tools needed. No scripts to call. Just respond with a single message that includes the user's wish text wrapped in a brief acknowledgment.

Format:

```
You said: 
```

That's the entire skill. Done.

## What this skill demonstrates

This SKILL.md format is the **standard Claude Code skill format**. The TAR Engine
reads this file and puts it in the LLM's system prompt. The LLM then produces a
response — for trivial skills like this one, no `run_bash` / `read_file` /
`write_file` tool calls are needed.

For skills that need data or scripts, the SKILL.md instructs the LLM to call
`run_bash` to invoke scripts in the same skill directory. See `url-summarize/SKILL.md`
in this pack for that pattern.
