Ponytail

Ponytail

Makes your AI agent think like the laziest senior dev in the room. The best code is the code you never wrote. Before writing anything, 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.

Reported impact vs a no-skill agent: 80–94% less code, 47–77% less cost, 3–6× faster across models.

Install

Portable across Claude Code, Codex, Gemini CLI, OpenCode and more (SKILL-based). With the skills CLI:

npx skills add DietrichGebert/ponytail

Or add it via your agent's plugin/marketplace system. See the repository for exact per-client steps.
