Ocpt

Ponytail plugin for OpenCode — makes your AI agent think like the laziest senior dev in the room.

Install

npm install @karnak19/ocpt

Then add to your opencode.json:

{
  "plugin": ["@karnak19/ocpt"]
}

What it does

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.

Commands

Command	What it does
/ponytail [lite|full|ultra|off]	Set the intensity, or turn it off. No argument reports the current level.
/ponytail-review	Review the current diff for over-engineering, hands back a delete-list.
/ponytail-audit	Audit the whole repo for over-engineering, not just the diff.
/ponytail-debt	Harvest the ponytail: shortcuts you've deferred into a ledger.
/ponytail-help	Quick reference for the commands above.

Levels

Level	What change
lite	Build what's asked, but name the lazier alternative in one line. User picks.
full	The ladder enforced. Stdlib and native first. Shortest diff, shortest explanation. Default.
ultra	YAGNI extremist. Deletion before addition. Ship the one-liner and challenge the rest of the requirement in the same breath.

Configuration

Set the default level with the PONYTAIL_DEFAULT_MODE environment variable:

export PONYTAIL_DEFAULT_MODE=ultra

Or just use /ponytail ultra in a session to switch for that session.

Why a standalone plugin?

The original ponytail repo requires you to run OpenCode from a checkout of their repo. This plugin is self-contained — install it and forget it.
