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

npm-scripts 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 6d 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 npm-scripts — 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

NPM Scripts Assistant

Help me with NPM scripts: $ARGUMENTS

Task

I'll help you work with package.json scripts by:

  1. Analyzing existing npm scripts in your project
  2. Creating new scripts or modifying existing ones
  3. Explaining what specific scripts do
  4. Suggesting improvements or optimizations
  5. Troubleshooting script execution issues

Process

I'll follow these steps:

  1. Examine your package.json file to understand current scripts
  2. Analyze dependencies and devDependencies for available tools
  3. Identify common patterns and conventions in your scripts
  4. Implement requested changes or create new scripts
  5. Provide explanations of how the scripts work
  6. Test scripts when possible to verify functionality

Common Script Types I Can Help With

  • Build processes (webpack, rollup, esbuild, etc.)
  • Development servers and hot reloading
  • Testing (unit, integration, e2e)
  • Linting and code formatting
  • Type checking
  • Deployment and CI/CD
  • Database migrations
  • Code generation
  • Environment setup
  • Pre/post hooks for git operations

Script Optimization Techniques

  • Parallelizing tasks for faster execution
  • Adding cross-platform compatibility
  • Improving error reporting and logging
  • Implementing watch modes for development
  • Creating composite scripts for common workflows
  • Adding appropriate exit codes for CI/CD pipelines

I'll adapt my approach based on your project's specific needs, dependencies, and build tools.

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.
