Whole-repo audit for over-engineering. Like ponytail-review, but scans the entire codebase instead of a diff: a ranked list of what to delete, simplify, or replace with stdlib/native equivalents. Use when the user says "audit this codebase", "audit for over-engineering", "what can I delete from this repo", "find bloat", "ponytail-audit", or "/ponytail-audit". One-shot report, does not apply fixes.

Harvest every `ponytail:` comment in the codebase into a debt ledger, so the deliberate shortcuts and deferrals ponytail leaves behind get tracked instead of rotting into "later means never". Use when the user says "ponytail debt", "/ponytail-debt", "what did ponytail defer", "list the shortcuts", "ponytail ledger", or "what did we mark to do later". One-shot report, changes nothing.

Show ponytail's measured impact as a compact scoreboard: less code, less cost, more speed, from the benchmark medians. One-shot display, not a persistent mode, and not a per-repo number. Trigger: /ponytail-gain, "ponytail gain", "what does ponytail save", "show ponytail impact", "ponytail scoreboard".

Quick-reference card for all ponytail modes, skills, and commands. One-shot display, not a persistent mode. Trigger: /ponytail-help, "ponytail help", "what ponytail commands", "how do I use ponytail".

Code review focused exclusively on over-engineering. Finds what to delete: reinvented standard library, unneeded dependencies, speculative abstractions, dead flexibility. One line per finding: location, what to cut, what replaces it. Use when the user says "review for over-engineering", "what can we delete", "is this over-engineered", "simplify review", or invokes /ponytail-review. Complements correctness-focused review, this one only hunts complexity.

Shape output for a reader with ADHD: lead with the next action, number multi-step work, restate state across turns, suppress tangents, give specific time estimates, make wins visible. Invoke with /i-have-adhd; stays on until "stop adhd mode".

Derive new Office files from structural selections without touching the original. Use when the user points at part of a spreadsheet, Word document, PDF, or PowerPoint deck (a worksheet range, paragraph, page, slide, shape, or a pasted selection-ref block) and wants it extracted, converted, or edited — the result is always a NEW file; the source file is never modified. Covers xlsx range extraction to csv/markdown/xlsx, docx paragraph extraction and text replacement, pdf page extraction, pptx slide/shape/table-cell extraction and editing, and targeted xlsx cell edits.

Interact with the user's visible Agent browser in Cherry Studio. Use for page navigation, authenticated websites, screenshots, forms, clicks, and browser debugging. Check live browser tools first; browser control requires the Browser setting and an available Agent pane.

Why AISkillsify

Real GitHub data, weekly

Stars, licenses, activity and new skills are refreshed from public repositories every week. We never invent ratings or download counts.

Licenses up front

Every skill shows its license before you install it, so you know what you can use, adapt or ship commercially.

Compatibility with evidence

Agent badges come from the skill file, a plugin marketplace or the author’s own repository topics, never from guesswork.

Custom skills when you need them

Can’t find it? Tell us your workflow and we’ll help build a skill around your standards and tools.

Frequently asked questions

What is an AI skill?
A skill is a folder of instructions, usually a SKILL.md file plus optional scripts and references, that an AI agent loads when a task calls for it. It teaches the agent a workflow, a set of conventions or how to use a tool, without you repeating that context in every prompt.
Which AI agents can use these skills?
The SKILL.md format started with Claude Code and is now read by several other agents. Each listing shows the agents it has evidence for: the SKILL.md names them, the repository ships a Claude Code plugin marketplace, or the author tagged the repository with them. Use the agent filter to see only skills for Codex, Cursor, Gemini CLI or OpenCode.
Are the skills free?
Every skill in the catalog today is free to install from its public GitHub repository, and 78% carry a recognized open-source license. Paid skills and packs will always be clearly labelled with a price before you install anything.
How do I install a skill?
Every skill page has an install command with a copy button, for example /plugin marketplace add owner/repo in Claude Code, or a git clone into your agent’s skills folder. Read the skill’s source before installing it: skills can instruct an agent to run commands.
How often is the catalog updated?
Weekly. A crawler reads public GitHub repositories, refreshes stars, licenses and activity, and adds new skills. The data on this site was last refreshed on September 24, 2026.
Can you build a custom skill for my team?
Yes. Describe what you want your agent to do — follow your coding standards, work with an internal tool, run a business process — and we’ll review it and get back to you with an approach and estimate.
