pnpm

pnpm is a cursor rule for Cursor from nedcodes-ok/cursorrules-collection. It costs 365 tokens per session, scanned A, original, MIT.

A set of guidelines for using pnpm, a package manager for JavaScript and TypeScript projects, especially projects containing several related packages in one repository.

In plain words
What is it for?
Use it to configure workspaces, link internal packages, run commands across selected packages, and coordinate builds in a monorepo.
Why use it?
It helps keep shared dependencies, scripts, versions, and installs consistent across a multi-package codebase.

Cursor rule for Cursor

Written for Cursor: a Cursor rule (.mdc).

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.

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 2d 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 Rules

Workspace Setup

  • Use pnpm-workspace.yaml to define workspace packages
  • Structure as packages/* or organized by type: apps/*, packages/*, tools/*
  • Use workspace protocol (workspace:) for internal dependencies
  • Configure shared dependencies in root package.json
  • Use workspace filtering with --filter flag for targeted operations

Package Management

  • Use exact versions for critical dependencies
  • Leverage peer dependencies for shared libraries
  • Use .pnpmrc for consistent configuration across team
  • Configure node-linker=hoisted only when absolutely necessary
  • Use shamefully-hoist=false for strict dependency isolation

Scripts & Commands

  • Define common scripts in root package.json for workspace-wide operations
  • Use pnpm -r for recursive operations across all packages
  • Use pnpm --filter for selective package operations
  • Create turbo.json or nx.json for build orchestration
  • Use pre/post hooks for lifecycle management

Performance

  • Use .pnpmrc to configure store-dir for optimal disk usage
  • Enable verify-store-integrity=false for faster installs in CI
  • Use frozen-lockfile=true in production environments
  • Configure registry mirrors for private packages
  • Use node_modules structure understanding for debugging

Monorepo Best Practices

  • Keep package versions synchronized using workspace ranges
  • Use shared ESLint, TypeScript configs from workspace packages
  • Configure path mapping in TypeScript for internal packages
  • Use consistent naming convention for internal packages (@scope/package-name)
  • Separate publishable packages from private workspace tools

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.
