setup-pm

setup-pm is a command for Claude Code, OpenCode from loulanyue/awesome-claude-notes. It costs 4 tokens per session (396 once invoked), scanned A, a copy of setup-pm, MIT.

A command for choosing which package manager a project uses, such as npm, pnpm, Yarn, or Bun. A package manager installs and runs a project's JavaScript dependencies and scripts.

In plain words
What is it for?
Use it to configure package-manager preferences, detect the choice from environment settings, project files, or lock files, and select a fallback when no preference is present.
Why use it?
It prevents setup commands from using the wrong tool for the project and can store the choice in project or global configuration.

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 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 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.
