A command that selects and records the package manager a JavaScript project should use, such as npm, pnpm, yarn, or bun. It can detect the choice from project files, environment settings, lock files, or available programs.

Use it to detect the current package manager, set a project or global preference, or list the supported package managers.

It avoids inconsistent dependency-install commands across developers and projects. The configuration can be set for one project or globally.

setup-pm — Command for Claude Code by Galaxy-Dawn

About the project

Claude Scholar is a semi-automated research assistant for academic research and software development, supporting literature review, coding, experiments, reporting, writing, and project knowledge management. Computer science and AI researchers use it across the research workflow with several coding-agent platforms; the catalogue contains its skills, commands, agents, hooks, plugin, and instruction.

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.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00014	$0.00404
Opus 5	$0.00007	$0.00202
Sonnet 5	$0.00003	$0.00081
Haiku 4.5	$0.00001	$0.00040

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 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

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:

Environment variable: CLAUDE_PACKAGE_MANAGER
Project config: .claude/package-manager.json
package.json: packageManager field
Lock file: Presence of package-lock.json, yarn.lock, pnpm-lock.yaml, or bun.lockb
Global config: ~/.claude/package-manager.json
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.
