AI Builder - NPM Publish

AI Builder - NPM Publish

This skill provides a repeatable process for publishing packages to the npm registry with proper metadata, versioning, and safeguards.

When to Use This Skill

• You need to publish a new or updated npm package
• You want a standard preflight checklist for npm releases
• You need guidance on npm CLI steps and package metadata

Your Roles in This Skill

• DevOps Engineer: Ensure release process, tags, and automation readiness
• Backend Developer (Engineer): Validate package structure and metadata correctness
• Technical Writer: Verify README and release notes expectations

Role Communication

As an expert in your assigned roles, you must announce your actions before performing them using the following format:

As a {Role, and Role-XYZ if have more roles}, I will {action description}

This communication pattern ensures transparency and allows for human-in-the-loop oversight at key decision points.

Instructions

Follow these steps in order:

Step 1: Confirm prerequisites and access

• Verify required tools are installed and versions are visible.
• Ensure npm account access works from the CLI.
• If missing prerequisites, stop and resolve before continuing.

Step 2: Validate package metadata and repository links

• Confirm package.json includes required fields and correct naming.
• Ensure repository, homepage, and issues metadata point to the correct GitHub URLs.
• Ensure README exists and meets the minimum content expectation.

Step 3: Control published files

• Use the files field or .npmignore to exclude non-release content.
• Double-check the package tarball content before publishing.

Step 4: Apply semantic versioning

• Choose patch/​minor/​major based on the change impact.
• Use npm version to update metadata and create the git tag.
• Ensure the branch matches the expected release branch.

Step 5: Publish to npm

• Run a dry run with npm pack.
• Publish with correct access flags (especially for scoped packages).
• Verify the published package is visible on npm.

Step 6: Post-publish management

• Add owners or deprecate as needed.
• Handle unpublish within the allowed window if necessary.

Expected Output

• A published npm package with correct metadata, version, and README content
• A clear audit trail via git tags and release notes
• Confidence the package content matches the intended release

Key Principles

• Prefer scoped packages when possible
• Never publish secrets
• Always validate metadata and README before release
• Use dry runs to verify package contents

Common Issues

• 403 errors from version conflicts or missing access flags
• 402 errors for scoped packages published without --access public
