# sttr Skill

This skill documents the sttr CLI and its supported commands so agents can discover and use them reliably.

## When to use

- The user requests a text transformation (hash, encode/decode, case change, JSON/YAML conversion).
- The user provides a string or file and asks for a conversion.
- You need a quick deterministic text conversion in a workflow.

## How to use

1. Pick the command from the list below.
2. Choose input mode:
   - Direct input: `sttr <command> "text"`
   - File input: `sttr <command> path/to/file.txt`
   - Pipe input: `echo "text" | sttr <command>`
3. Return the output only; avoid interactive mode unless explicitly requested.
