setup-pm

setup-pm is a command for Claude Code from sifxprime/kodelyth-ecc. It costs 14 tokens per session (404 once invoked), scanned A, a copy of setup-pm, MIT.

A command that selects which JavaScript package manager a project or user preference should use, such as npm, pnpm, yarn, or bun.

In plain words
What is it for?
Use it to detect the current choice, set a project or global preference, or list the supported package managers.
Why use it?
It prevents inconsistent package-manager choices across commands and projects, which can cause dependency or lock-file problems.

Command for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: reads .claude/ paths.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node scripts/setup-package-manager.js --detect.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo
git clone --depth 1 https://github.com/sifxprime/kodelyth-ecc

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

setup-pm 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.

Origin

This is a copy

100% identical to setup-pm — 0 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.

What it actually says

Package Manager Setup

Configure your preferred package manager for this project or globally.

Usage

# Detect current package manager
node scripts/setup-package-manager.js --detect

# Set global preference
node scripts/setup-package-manager.js --global pnpm

# Set project preference
node scripts/setup-package-manager.js --project bun

# List available package managers
node scripts/setup-package-manager.js --list

Detection Priority

When determining which package manager to use, the following order is checked:

  1. Environment variable: CLAUDE_PACKAGE_MANAGER
  2. Project config: .claude/package-manager.json
  3. package.json: packageManager field
  4. Lock file: Presence of package-lock.json, yarn.lock, pnpm-lock.yaml, or bun.lockb
  5. Global config: ~/.claude/package-manager.json
  6. Fallback: First available package manager (pnpm > bun > yarn > npm)

Configuration Files

Global Configuration

// ~/.claude/package-manager.json
{
  "packageManager": "pnpm"
}

Project Configuration

// .claude/package-manager.json
{
  "packageManager": "bun"
}

package.json

{
  "packageManager": "[email protected]"
}

Environment Variable

Set CLAUDE_PACKAGE_MANAGER to override all other detection methods:

# Windows (PowerShell)
$env:CLAUDE_PACKAGE_MANAGER = "pnpm"

# macOS/Linux
export CLAUDE_PACKAGE_MANAGER=pnpm

Run the Detection

To see current package manager detection results, run:

node scripts/setup-package-manager.js --detect
Changes

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.
