mimocode-ponytail

mimocode-ponytail is a tool for MiMoCode that enforces YAGNI (You Aren't Gonna Need It) principles by injecting rules via file hooks. It is described as "Lazy senior dev mode for MiMoCode — YAGNI rules injected automatically via file hooks." The tool forces the laziest solution that actually works, following a ladder: skip if not needed, use standard library, use native platform features, use already-installed dependencies, or write one line before considering a minimum implementation.

The tool works by leveraging MiMoCode's file hooks system. It loads a hook file at ~/.config/mimocode/hooks/ponytail.ts. This hook injects YAGNI rules into the system prompt before every LLM call, ensuring the agent stays in ponytail mode across the entire session. It also handles /ponytail commands and persists the mode to a file.

mimocode-ponytail provides several commands to control its behavior, such as /ponytail to show the current mode, /ponytail lite, /ponytail full, and /ponytail ultra to set intensity levels, and /ponytail off to disable it. It also includes commands for reviewing diffs for over-engineering, auditing repositories for bloat, listing deferred shortcuts, showing an impact scoreboard, and displaying a quick reference. The tool comes with 6 bundled skills and is an adaptation of DietrichGebert/ponytail for MiMoCode's file hooks system.
