Anthony Fu's Skills

A collection of Agent Skills reflecting Anthony Fu's preferences, experience, and best practices, along with usage documentation for the tools.

[!IMPORTANT] This is a proof-of-concept project for generating agent skills from source documentation and keeping them in sync. I haven't fully tested how well the skills perform in practice, so feedback and contributions are greatly welcome.

Installation

This repo mainly hosts the skills. The recommended way to use them is @antfu/skills, a skills pack installed with skills-npm. Besides my own skills, the pack includes curated skills from other authors, and your package manager keeps them in sync:

pnpm i -D skills-npm @antfu/skills
pnpx skills-npm setup

See antfu/skills-pack for the full list of skills in the pack.

Install From This Repo

To install skills from this repo directly, use the skills CLI:

pnpx skills add antfu/skills --skill='*'

or to install all of them globally:

pnpx skills add antfu/skills --skill='*' -g

Skills

This repo includes skills from different sources with different scopes.

Hand-maintained Skills

Opinionated

Manually maintained by Anthony Fu with his preferred tools, setup conventions, and best practices.

Skill	Description
antfu	Anthony Fu's preferences and best practices for app/library projects (eslint, pnpm, vitest, vue, etc.)
antfu-create-pr	Open reviewable PRs: Conventional Commits title, evidence-based body, before/after screenshots via gh --attach (adapted from moeru-ai/airi)
antfu-issue-triage	Triage issues and PRs of the current repo: find fixed, duplicate, and spam items, suggest labels, gauge demand, and confirm an action table before acting
antfu-query	Interview the user about a plan or decision in rounds via the agent's question tool until reaching shared understanding (adapted from mattpocock/skills)
antfu-simplify	Simplify the current PR or changes with an ablation study: keep only what is proven needed, with just-right abstraction, minimal, robust, and universal code

[!TIP] For design, see antfu/design, which ships the antfu-design skill alongside the @antfu/design package.

FAQ

What Makes This Collection Different?

This collection is opinionated, but the key difference is that it clones the source documentation locally (into the git-ignored sources/) and generates skills directly from it. This provides more reliable context and allows the skills to stay up-to-date with upstream changes over time.

The project is also designed to be flexible - you can use it as a template to generate your own skills collection.

Skills vs llms.txt vs AGENTS.md

To me, the value of skills lies in being shareable and on-demand.

Being shareable makes prompts easier to manage and reuse across projects. Being on-demand means skills can be pulled in as needed, scaling far beyond what any agent's context window could fit at once.

You might hear people say "AGENTS.md outperforms skills". I think that's true — AGENTS.md loads everything upfront, so agents always respect it, whereas skills can have false negatives where agents don't pull them in when you'd expect. That said, I see this more as a gap in tooling and integration that will improve over time. Skills are really just a standardized format for agents to consume—plain markdown files at the end of the day. Think of them as a knowledge base for agents. If you want certain skills to always apply, you can reference them directly in your AGENTS.md.

Generate Your Own Skills

Fork this project to create your own customized skill collection.

1. Fork or clone this repository
2. Install dependencies: pnpm install
3. Update meta.ts with your own projects and skill sources
4. Run pnpm start cleanup to remove existing sources and skills
5. Run pnpm start init to clone the sources
6. Run pnpm start sync to pull the latest source docs
7. Ask your agent to Generate skills for \<project\> (recommended one at a time to manage token usage)

See AGENTS.md for detailed generation guidelines.
