   LLM Tails open-source bundle brings disciplined rules to coding agents

   The author of LLM Tails says the MIT-licensed project combines Ponytail and LLM Wiki through prompts, hooks, and skills that encourage coding agents to read first, write minimally, and verify claims. The author says it has no dependencies and works with Claude Code, Cursor, GitHub Copilot, Codex, Gemini, Windsurf, Cline, and Kiro. Claims about smaller codebases, lower token use, and fewer hallucinations are not supported by numerical results, while the referenced same-prompt comparison image is not available in the supplied report.

   Ponytail 5 coding-agent skill claims 53% less code in self-reported benchmark

   Ponytail 5 is a rebuilt version of the Ponytail skill for coding agents, distributed as the MIT-licensed GitHub repository DietrichGebert/ponytail and loaded into tools such as Claude Code and Codex as a prompt (SKILL.md or AGENTS.md). The project reports a comparison in Claude Code of the same agent with and without the skill across 39 tasks, including a real FastAPI + React repo with Opus 5.5 and five runs each: 53% less code, 41% less time, 26% lower cost and 45% fewer tokens, plus 98% of risky logic shipping with a test versus 68% without. The project also describes a reworked review command, a repo-wide audit command, and a version 5.3 status band above the prompt in Claude Code showing task cost, tokens, agent time, code reuse and whether tests passed, requiring Claude Code 2.1.290 or later. All figures are self-reported by the project and no independent replication is supplied.
