# OpenCLI Agent Pack: Miller

Use this when an AI agent needs to work with `mlr`.

## What this CLI is for
CSV transforms, stream processing, and data shaping from the terminal. Built by John Kerl.

Best for: csv transforms, stream processing, and data shaping from the terminal.

## Agent readiness
Usable with guardrails (50/100)
- Supports non-interactive/scripted use.
- Works well in CI or repeatable automation.

## Install
```sh
brew install miller
```

## Verify before real work
```sh
mlr --version
```
Expected signal: mlr responds locally and is ready for the first real command.

## Safe starting commands
```sh
mlr --version
```

```sh
mlr --csv cut -f name,email data.csv
```

## Guardrails for agents
- Prefer small commands and ask the agent to summarize plain text output.

## Suggested agent instruction
You may use Miller (`mlr`) for csv transforms, stream processing, and data shaping from the terminal.. First install it if missing, then run the verify command. Start with read-only or inspection commands. Summarize what you found before changing anything. Ask for confirmation before commands that mutate remote state, spend money, deploy, delete data, merge code, or expose secrets.
