ponytail

Write-less-code ruleset

FreePlanning & reasoninggithub.com

What it is

A ruleset premised on 'the best code is code you never wrote'. Applies a seven-rung decision ladder forcing the agent to exhaust stdlib, existing project code and dependencies before writing anything new. Repo claims ~54% less code, 20% cheaper, 27% faster. ~104k stars.

Why it earns a slot

Directly relevant to a Lovable project, where the failure mode is Claude re-implementing a component that already exists three folders over. Also ships review, audit and debt-tracking commands.

How ponytail sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
