Skill/plugin that pushes agents toward the smallest safe change (native `<input type=\"date\">` over a date-picker library). Published agentic benches on a real FastAPI+React repo claim ~54% mean LOC cut, ~20% cheaper, ~27% faster, 100% safety vs no-skill baseline; npm `@dietrichgebert/ponytail` plus OpenClaw/Claude/Cursor install paths. Reproduce scripts live in-repo.","theCatch":"Same inflated-★ caution as other viral skill packs — rank the benches and diffs, not the counter. Vs Caveman (terse-prose / token-compression skill+proxy, BSL engine bits) and anti-slop (UI/copy slop filter + delivery gate): Ponytail is YAGNI/minimal-implementation discipline with published LOC/cost benches, not output-style compression and not a design-slop filter. Waitlist banner (“Something’s coming”) is a future tease at ponytail.dev/soon — not a paid wall on the MIT skill.","verdict":"MIT laziest-senior skill when agents over-build; trust the published benches over the ★ count — waitlist is tease, not tollbooth.","addedAt":"2026-09-29","featured":false,"domain":"AI Agents","subSpecialty":"Skills","subcategory":"Skills","tags":["self-host","permissive","coding-agents","skills","active","young-repo","fast-stars"],"capabilities":["skills","yagni","tokens"],"surfaces":["Self-host"],"ecosystem":["Multi-platform"],"licenseModel":"OSS/MIT","githubStars":167213,"starsPerWeek":9033,"access":"free","archived":false,"repo":{"createdAt":"2026-06-12","pushedAt":"2026-10-18","license":"MIT","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/ponytail","html":"/gems/ponytail","markdown":"/gems/ponytail.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
