Install

Each tab says whether it installs commit 09c434a, the one we checked, or the latest version.

No tab for your agent? Use Any agent for OpenCode, Goose, Windsurf (Devin Desktop), Zed, Roo Code, Factory Droid, Junie, Amp and Antigravity, and Claude Code for Cline. Kiro needs the folder copied by hand.

Pinned to commit 09c434a, the one we checked.

From your project's root folder:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/DietrichGebert/ponytail.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin 09c434ab73ca43761c5d8b0c5d341926c2fba710 &&
  git -C "$tmp" sparse-checkout set -- skills/ponytail-audit &&
  git -C "$tmp" checkout -q 09c434ab73ca43761c5d8b0c5d341926c2fba710 &&
  mkdir -p .claude/skills &&
  mkdir .claude/skills/ponytail-audit &&
  cp -R "$tmp"/skills/ponytail-audit/. .claude/skills/ponytail-audit/ &&
  rm -rf "$tmp"

If Claude Code was already running and this created the skills folder, run /reload-skills.

Or install the ponytail plugin it ships in. Installs the latest version, not the one we checked. Installs everything in the plugin, including any hooks, MCP servers and scripts our check doesn't cover.

  out="$(mktemp -d)" &&
  cp -R "$tmp"/skills/ponytail-audit "$out"/ponytail-audit &&
  (cd "$out" && zip -qr - ponytail-audit) > ponytail-audit.zip &&
  rm -rf "$tmp" "$out"

In Claude, open Customize > Skills, select +, then + Create skill > Upload a skill, and choose ponytail-audit.zip.

Gemini CLI docs

Pinned to commit 09c434a, the one we checked.

Codex, Cursor, Copilot, VS Code, Gemini CLI, OpenCode, Goose, Amp and Zed all read .agents/skills; Claude Code and Kiro list only their own folders.

From your project's root folder:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/DietrichGebert/ponytail.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin 09c434ab73ca43761c5d8b0c5d341926c2fba710 &&

  mkdir -p .agents/skills &&
  mkdir .agents/skills/ponytail-audit &&
  cp -R "$tmp"/skills/ponytail-audit/. .agents/skills/ponytail-audit/ &&
  rm -rf "$tmp"

Or use the skills CLI from skills.sh. Installs the latest version, not the one we checked. The skills CLI reports installs to skills.sh unless you set DISABLE_TELEMETRY=1.

Agent Skills docs

What it can touch

From the files and frontmatter at commit 09c434a. This is how much a skill can do, not whether it is risky.

What it can touch: Instructions only

It is instructions only: no scripts, no named hosts and no pre-approved tools.

Pattern check

Pattern check: nothing flagged · commit 09c434a · 26 Oct 2026

We checked every text file in this skill, at commit 09c434a on 26 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

How the check works Report an incorrect finding

Format check

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

Agent Skills specPasses
The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.
- Note
  There is no license field, so readers can't tell whether they may reuse the skill. O2
  Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.
Claude CodePasses
Claude apps & API uploadPasses
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Note
  The description is 346 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
  Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
OpenAI (Codex & API)Passes
VS Code & CopilotPasses

DietrichGebert/ponytail
Lazy senior dev mode: the smallest change that fully solves the task, and a reply a busy human understands in one read. Use on any coding task (writing, fixing, refactoring, reviewing, choosing dependencies) and when the user says "ponytail", "be lazy", "simplest solution", "yagni", or complains about over-engineering or bloat. Levels: lite, full (default), ultra.
