pnpm

pnpm is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 19 tokens per session (398 once invoked), scanned A, original, MIT.

A guide to pnpm, a package manager for Node.js projects that shares downloaded packages to save disk space and speed up installs.

In plain words
What is it for?
Use it to install JavaScript packages, manage several related packages, run commands across a workspace, and keep shared versions consistent.
Why use it?
It prevents undeclared dependencies from being used accidentally and provides strong support for workspaces and monorepos.

Token cost

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.

Security

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 7d 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.

What it actually says

pnpm

pnpm is fast and disk-efficient. It uses a Content Addressable Store and hard links to avoid duplicating packages. v9 (2025) adds Catalogs.

When to Use

  • Disk Space: Saves GBs by storing one copy of lodash globally.
  • Speed: Installation is instant if packages are already in the store.
  • Monorepos: Excellent workspace support with strict isolation.

Quick Start

# Enable via Corepack
corepack enable
corepack prepare pnpm@latest --activate

pnpm add next

Core Concepts

Content Addressable Store

~/.local/share/pnpm/store. All packages live here. Projects assume node_modules structure via symlinks.

Strict Resolution

Unlike npm/yarn (classic), pnpm does not flatten node_modules. You cannot access dependency-of-dependency unless you declare it.

Catalogs (v9)

Define version groups in pnpm-workspace.yaml. e.g. catalog:react-18 ensures all packages use exact same versions.

Best Practices (2025)

Do:

  • Use CI Caching: pnpm is fast, but setup pnpm-store caching in GitHub Actions to make it instant.
  • Use pnpm -r: Run commands recursively across the monorepo.
  • Use only-allow: Add preinstall script to force team to use pnpm.

Don't:

  • Don't shame hoist: If legacy tools break with symlinks, use shamefully-hoist=true in .npmrc as a temporary fix.

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.
