Anthony Fu's Skills is a curated collection of instructions that guide coding agents in using particular tools, frameworks, and development practices. It is mainly aimed at projects using technologies such as Vite, Nuxt, Vue, TypeScript, and related JavaScript tooling. The catalogue entries are skills and instructions from this collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.01176 |
| Opus 5.5 | $0.00020 | $0.00470 |
| Sonnet 5.5 | $0.00010 | $0.00235 |
| Haiku 4.5 | $0.00005 | $0.00118 |
Grade A, and why
pnpm scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 25d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to pnpm — 15 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.
pnpm is a fast, disk space efficient package manager. It uses a content-addressable store to deduplicate packages across all projects on a machine, and enforces strict dependency resolution by default, preventing phantom dependencies.
pnpm v12 is a Rust rewrite of v11: stable, and keeps v11's commands, flags, settings, and lockfile format — so most guidance here applies to both. A handful of v12 behaviors differ (git deps resolve via HTTPS, project-aware global bins, other package managers, packageImportMethod: auto hardlinks first on Linux, --resolution-only removed) — see best-practices-migration.
Configuration model (important): pnpm settings live in pnpm-workspace.yaml (and the global config.yaml) using camelCase keys. .npmrc is used only for authentication/registry credentials, and the pnpm field of package.json is no longer read. When working in a pnpm project, check pnpm-workspace.yaml for settings/workspace structure and .npmrc only for auth. Always use --frozen-lockfile (or pnpm ci) in CI.
The skill is based on pnpm 12.x, generated at 2026-09-25. It covers v11+v12 behavior (config split, isolated global packages,
allowBuilds,pmOnFail, global virtual store, native release management, workspace task orchestration, and experimental Python/Cargo support) where current docs describe them.
Core
| Topic | Description | Reference |
|---|---|---|
| CLI Commands | install/add/remove/update, run, dlx/pnx, workspace, runtime, publishing (version, view, sbom, stage) | core-cli |
| Configuration | pnpm-workspace.yaml settings (camelCase), global config.yaml, packageConfigs, .npmrc auth | core-config |
| Workspaces | Monorepo support: filtering, workspace protocol, shared lockfile, packageConfigs | core-workspaces |
| Store | Content-addressable store, virtual store, node linker modes, frozen/read-only store | core-store |
What ships with it
20 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pnpm is a skill published in the GitHub repository antfu/skills (6,006 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 1,176 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to pnpm, differing in 15 lines, and is treated as a copy.
