npm-publish-agent

npm-publish-agent is a cursor rule for Cursor from rosendolu/cursor-rules-deploy. It costs 5 tokens per session (1,120 once invoked), scanned A, original, MIT.

A set of rules for publishing JavaScript or TypeScript packages to npm, the package registry used to share code. It describes automated releases through GitHub Actions, version tags, authentication, tests, and package checks.

In plain words
What is it for?
Use it when setting up or maintaining an npm release process, including GitHub workflows, package configuration, registry selection, testing, and release validation.
Why use it?
It reduces release mistakes such as publishing untested code, exposing tokens, or creating incomplete package metadata. It also keeps versioning and changelogs consistent.

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-publish-agent 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 5d 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.

NPM Package Publishing Guidelines

Critical Rules

  • Always use GitHub Actions for automated package publishing
  • Store authentication tokens as GitHub Secrets, never in code
  • Use conventional commits format for automated versioning
  • Validate packages by building and testing before publishing
  • Tag releases with version numbers prefixed with 'v' (e.g., v1.0.0)
  • Configure workflows to trigger on both tag pushes and manual events
  • Generate and maintain changelogs for all releases
  • Ensure package.json contains all required fields before publishing
  • Scope packages appropriately (public/private, org-scoped)
  • Verify package contents before publishing using npm pack
  • Use a consolidated workflow for both npm and GitHub Packages publishing

GitHub Actions Setup Requirements

  • Create .github/workflows/package-publish.yml for a unified publishing workflow
  • Include registry selection in workflow_dispatch inputs
  • Set proper permissions in workflow file (contents:write, packages:write)
  • Configure Node.js environment using actions/setup-node@v4
  • Set registry URL based on selected target registry
  • Cache dependencies using the cache parameter
  • Run tests before publishing
  • Generate changelog using conventional-changelog-cli

Package Configuration Requirements

  • Valid package.json with all required fields:
    • name, version, description, main, files
    • scripts (build, test)
    • publishConfig (access, registry)
    • repository information
  • Package should be properly scoped for GitHub Packages (@username/package-name)
  • Files array should include only distribution files, not source code
  • Include README.md, LICENSE, and CHANGELOG.md

Security Guidelines

  • NPM_TOKEN must be stored as a GitHub Secret
  • Use GITHUB_TOKEN with minimal required permissions
  • Generate fresh tokens periodically
  • Do not expose tokens in logs or outputs
  • Use permission boundaries in GitHub Actions workflows

Version Management

  • Use semantic versioning (MAJOR.MINOR.PATCH)
  • Automate version bumps based on conventional commits:
    • fix: patch version update
    • feat: minor version update
    • BREAKING CHANGE: major version update
  • Use npm version to update package.json and create tags
  • Push tags to trigger automated releases

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.
