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 1mo 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

/setup-pm --detect           # Detect current package manager
/setup-pm --global pnpm      # Set global preference
/setup-pm --project bun      # Set project preference
/setup-pm --list              # List available package managers

Detection Priority

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

Configuration Files

Global

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

Project

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