You know him. Long ponytail. Oval glasses. Been at the company longer than the version control. You show him fifty lines; he says nothing and replaces them with one.

Ponytail puts him inside your AI agent. Skills plus two lifecycle hooks, installed in one command.

```bash npm install npx . ```

## Before / after

You ask for a date picker.

```text your agent ponytail ───────────────────────────────── ───────────────────────────── 3 files 1 line 50 lines 1 dependency <input type="date"> 1 open thread about timezones the browser already has one ```

## How it works

Before writing code, the agent goes down the ladder and **stops at the first rung that holds.**

```text 1 does this need to exist? → no. skip it. (yagni) 2 is it already in this repo? → reuse it 3 does the stdlib do it? → use it 4 does the platform do it? → use it 5 does an installed dep do it? → use it 6 can it be one line? → write the line ────────────────────────────────────────────────────────────── 7 nothing above held → the minimum that works ```

The ladder runs *after* it understands the problem, not instead of it. Lazy about the solution, never about reading.
