secure-npm-package: Workflow Automation for AI Agents | OpenAgentSkill

Overview

Set up a secure release process for an npm package to protect it from supply chain attacks. Use for any request to create and publish a new npm package, secure npm publishing or releasing, set up npm Trusted Publishing, provenance, or Staged Publishing, harden a release workflow.

Release an npm package securely

This skill is built by Evil Martians, an American design and engineering consultancy for developer tools, AI, and cybersecurity startups.

Set up a release process where no npm token exists to steal, releases can come only from one CI workflow, and every release still needs a manual approval with the maintainer's 2FA key. Companion to https://evilmartians.com/chronicles/the-secure-way-to-release-an-npm-package.

How to run this skill

The setup is half repo files, half settings on npmjs.com and github.com that only the user can change. The settings are the part that needs the user, and if you do the repo changes first the instructions scroll past and get missed — so the user acts before you do. For the settings, produce click-by-click instructions with direct links resolved from the repo's real data — package names from package.json, owner/repo from the repository field — and the exact values to enter. Never say "go to your package settings"; always give the resolved URL.

The order is strict — questions, then manual settings, then CLI and files:

Gather facts (Step 1), read-only and silent, to learn the project's shape.
Ask all questions together. Gather every decision you need from the user — cooldown length (1 or 3 days), whether to move build tools into dependencies for the --omit=dev hack in a monorepo, the repository field if it's missing, and anything else the project raises — and ask them all in one message. Do not drip questions out one at a time. Wait for the answers.
Hand off the manual settings (Step 2) on npmjs.com and github.com and ask the user to make every change.
Wait for the user to confirm they have changed everything — do not run any repo-changing command or touch any files until they say so.
Run the CLI and change files (Step 3).

The only commands allowed before the user answers the questions and confirms the settings are the read-only fact-gathering ones in Step 1 (npm view, git tag, reading package.json). Every mutating command — npm config set, writing workflow files, editing package.json — waits for Step 3.

Step 1: Gather facts

Collect before changing anything:

Packages. Read the root package.json. If it has workspaces (or pnpm-workspace.yaml exists), it's a monorepo: enumerate every workspace package.json. Only packages without "private": true need npm settings.
GitHub owner/repo. From the repository field (normalize git+https://github.com/owner/repo.git, github:owner/repo, owner/repo), falling back to git remote get-url origin. If neither exists, ask the user, then add the repository field.
Org or personal. Whether the owner is a GitHub organization or a user account (changes the 2FA instructions).
Package manager and version. From the packageManager field and lockfiles.
Published or not. npm view <name> version for each public package. An E404 means not yet published — see Not yet published packages.
Tag format. Check existing version tags with git tag --sort=-creatordate | head — some repos use v1.0.0, others 1.0.0, monorepos often <name>@1.0.0. Keep the existing format in the workflow trigger and release instructions; only if there are no tags yet, default to v1.0.0.
Build step. Is there a build script, and what directory does it emit?
Existing workflows in .github/workflows/, especially any current release workflow and any use of secrets.NPM_TOKEN.

Step 2: Manual settings (ask the user first)

Present these before changing any repo files, so the user doesn't miss them. Give a numbered checklist with resolved links and exact values, grouped by website. The workflow filename you reference below (publish.yaml) is fixed — you'll create the file in Step 3, but the user can enter the name now without waiting for it. Ask the user to work through the whole checklist and then confirm back that everything is done. After they confirm, verify what you can (npm view <name>, gh api repos/<owner>/<repo>/rulesets if gh is authenticated) and re-ask about anything still not set. Only once the settings are confirmed do you move on to the repo changes.

On npmjs.com — for every public package

Repeat this block per package in a monorepo, each with its own link:

Open https://www.npmjs.com/package/<name>/access (you must be logged in as a maintainer).

In Trusted Publisher select GitHub Actions and enter:

Organization or user: <owner>

Repository: <repo>

Workflow filename: publish.yaml

Environment: leave empty

Enable only Allow npm stage publish — deny plain npm publish, so even hacked CI can't release without your approval.

In Publishing access select Require two-factor authentication and disallow tokens. This revokes all existing tokens — warn me first if any other automation publishes this package with a token.

If the old setup used an NPM_TOKEN secret, also:

Delete the NPM_TOKEN secret at https://github.com/<owner>/<repo>/settings/secrets/actions and revoke the token itself at https://www.npmjs.com/settings/~/tokens.

On github.com

2FA for everyone. If the repo belongs to an organization:

Open https://github.com/organizations/<org>/settings/security and enable Require two-factor authentication under Authentication security.

For a personal account, ask the user to confirm 2FA is on at https://github.com/settings/security — prefer a hardware key or passkey.

Tag ruleset — with CI publishing, whoever can push a v* tag can trigger a release, so restrict tag creation:

Open https://github.com/<owner>/<repo>/settings/rules/new?target=tag and create:

Ruleset Name: Tags only by admins

Enforcement status: Active

Bypass list: add Repository admins

Target tags: Include all tags

Tag rules: enable Restrict creations

Immutable releases — once a release is published, its tag and assets can never be changed or deleted, so an attacker can't silently swap artifacts under an existing version:

Open https://github.com/<owner>/<repo>/settings and in the Releases section enable Immutable releases.

Step 3: Repo changes (do these yourself)

Do not start until the user confirms they have changed everything in Step 2. Ask them to confirm the npm and github settings are all done, and wait for their explicit yes. Only then make the repo changes. Ask before overwriting an existing release workflow; carry over intentional extras (changelog generation, GitHub Releases) into separate jobs without id-token.

3a. `.github/workflows/publish.yaml`

The core rules, whatever the project's shape:

Trigger on version tags, matching the repo's existing tag format (v*, [0-9]*, …).
The publish job installs no dependencies, uses no cache, and no third-party actions beyond checkout/setup-node/download-artifact. Anything running in a job with id-token: write can publish the package.
Build in a separate job, pass output via artifacts. Only the publish job gets id-token: write; every job gets contents: read and persist-credentials: false on checkout.
--ignore-scripts on every install and on publish.
npm stage publish, not npm publish — CI stages the release, a human approves it with 2FA.
Use npm for the publish command even when the project uses pnpm, yarn, or bun. . The only exception is a project that genuinely needs its own package manager's staged-publish command (e.g. workspace: or beforePacking); there, use that tool's command instead.
If there is no build script, drop the build job and the artifact steps entirely (best case — see Nano ID's workflow).

Template (adapt Node version, build output path, and install commands to the project's package manager, update versions to latest keeping SHA-commits pinning):

If an old workflow used secrets.NPM_TOKEN, remove it from the YAML now — deleting the secret and revoking the token is already covered by the Step 2 checklist (from the facts gathered in Step 1).

3b. Run zizmor locally and fix every finding

docker run --rm -t -v "$(pwd):/repo:ro" ghcr.io/zizmorcore/zizmor:latest /repo/.github/workflows

Run it yourself if Docker is available; otherwise ask the user to run this command and paste the output. Fix everything it reports in the existing workflows (pull_request_target misuse, shell injection, unpinned actions), then re-run until clean. Remind the user to delete stale branches that still contain old vulnerable workflows — attackers exploit old branches (that's how Nx was hit).

3c. `.github/workflows/check-workflows.yaml` — keep linting on CI
