You know him. Long ponytail. Oval glasses. Has been at the company longer than the version control. You show him fifty lines; he looks at them, says nothing, and replaces them with one.
|
||
|
||
Ponytail puts him inside your AI agent.
|
||
|
||
## Before / after
|
||
|
||
You ask for a date picker. Your agent installs flatpickr, writes a wrapper component, adds a stylesheet, and starts a discussion about timezones.
|
||
|
||
With ponytail:
|
||
|
||
```html
|
||
<!-- ponytail: browser has one -->
|
||
<input type="date">
|
||
```
|
||
|
||

||
## How it works
|
||
|
||
Before writing code, the agent stops at the first rung that holds:
|
||
|
||
```
|
||
1. Does this need to exist? → no: skip it (YAGNI)
|
||
2. Stdlib does it? → use it
|
||
3. Native platform feature? → use it
|
||
4. Installed dependency? → use it
|
||
5. One line? → one line
|
||
6. Only then: the minimum that works
|
||
```
|
||
|
||
Lazy, not negligent: trust-boundary validation, data-loss handling, security, and accessibility are never on the chopping block.
|
||
|
||
## Install
|
||
|
||
The most effort ponytail will ever ask of you:
|
||
|
||
```
|
||
/plugin marketplace add DietrichGebert/ponytail
|
||
/plugin install ponytail@ponytail
|
||
```
|
||
|
||
That was it. He'd be proud. He won't say it.
|
||
|
||
Active every session. `/ponytail-review` finds what to delete in your diff. `/ponytail ultra` exists for when the codebase has wronged you personally. `/ponytail-help` explains the rest.

## FAQ
|
||
|
||
**Does it need a config file?**
|
||
No.
|
||
|
||
**What if I really need the 120-line cache class?**
|
||
You don't. Insist anyway and he'll build it — slowly, correctly, while looking at you.
|
||
|
||
**Does it scale?**
|
||
The code you never wrote scales infinitely. Zero bugs, zero CVEs, 100% uptime since forever.
|
||
|
||
**Why "ponytail"?**
|
||
You know exactly why.
|
||
|
||
## Numbers
|
||
|
||
5 coding tasks, same agent with and without ponytail: **−16% tokens, ~4× faster, 293 → 47 lines.** The 246 lines nobody wrote have never caused an incident. Data: [benchmarks/](benchmarks/).
