| description | Bootstrap the first publication of an npm package and wire up Trusted Publishing (GitHub OIDC) in a monorepo. Use whenever a new package must be published to npm for the first time, when configuring npm trust github or a trusted publisher, when handing a package over from manual releases to CI-owned releases, or when diagnosing first-release failures such as EOTP, PUT 404, EPUBLISHCONFLICT, 401 on whoami, or "Package not found" during trust setup. |
npm package first release
npm OIDC Trusted Publishing cannot create the first version of a package
that does not exist yet, and a trust relationship cannot be created for a
package that does not exist. The first version therefore needs one deliberate,
human-in-the-loop publication; every later version is owned by CI. This skill
walks that bootstrap and hands off cleanly.
Hard rules
- Never ask the user to paste an OTP code into chat, and never automate
npm login, browser approval, or OTP entry. Interactive steps belong to the
user's own terminal, where prompts and browsers are visible to them.
- Publish before configuring trust.
npm trust github on an unpublished
package fails with 404 Package not found โ that error means ordering, not
a missing name.
- In pnpm workspaces always publish with
pnpm publish. It rewrites
workspace:* dependencies to real versions; plain npm publish would ship
an unresolvable manifest.
- Do not run recursive root-level publishes (
pnpm -r publish). Publish one
package from its directory.
Procedure
0. Preconditions
- The package name is on the repository's release allowlist (for pi-packages:
scripts/publish-release.mjs), so CI can take over after handoff.
- Version/changeset coordination is decided: either a pending changeset will
produce a version PR, or the manifest version is already the exact version
intended for first publication. The registry-aware CI publisher skips
versions equal to what is on npm, so publishing an exact version early is
safe.
1. Check credentials before anything else
npm whoami
- Success: continue.
E401: the stored token is dead. npm actively retires bypass-2FA tokens, so
tokens die silently even days after login. Ask the user to run npm login
themselves and confirm when done. Do not proceed on a dead token.
A dead token is also why a publish of a brand-new package can fail with
PUT ... 404 Not Found: the registry masks authorization failures for
nonexistent packages as 404 instead of 401/403. When you see 404 on PUT,
check npm whoami first before suspecting the package name.
2. Check registry state
curl -s https://registry.npmjs.org/<package-name>
- 404: name is free โ full bootstrap below.
- HTTP 200 with no versions/dist-tags: the name was unpublished once
(tombstone); it can still be published after the 24-hour window.
- Existing versions: this is not a first release โ stop and reassess.
3. User publishes the first version (interactive)
The user runs, from the package directory:
pnpm publish --access public
pnpm prompts Enter OTP: inline; they type their authenticator code. If the
branch is not the configured publish branch, pnpm asks to continue โ answering
yes is expected on wip/release branches.
If the user must publish the exact version a changesets version PR produces,
check out that PR's branch and publish from there, then merge it; the CI
publisher compares local vs registry versions and skips what already exists.
4. Establish the trust relationship
Still the user's terminal:
npm trust github <package-name> --file <release-workflow>.yml \
--repo <owner>/<repo> --allow-publish -y
For pi-packages: --file release.yml --repo FradSer/pi-packages. This prints
an auth URL and waits ("Press ENTER to open in the browser..."); the user
approves in their browser. Requires npm >= 11.5.
If this fails with Package not found, step 3 has not actually completed โ
verify the registry before retrying.
5. Hand off to CI
Merge the feature/version PR. The release workflow's registry-aware publisher
sees the published version and skips it; all subsequent versions publish via
GitHub Actions OIDC with provenance โ no local token involved ever again.
6. Verify
curl -s https://registry.npmjs.org/<package-name> | jq '."dist-tags".latest'
Registry edge caches can lag briefly after publish.
Failure quick table
| Symptom | Real cause | Fix |
|---|
PUT ... 404 Not Found on a new package | Dead token masked by the registry | npm whoami; if E401, user re-runs npm login |
EOTP exiting immediately under automation | Non-TTY clients cannot complete web-auth | Stop automating; user runs the publish interactively |
Trust setup: Package not found | Package not published yet | Complete step 3 first, then re-run trust |
EPUBLISHCONFLICT / version exists | Version already on npm | Advance the version; never overwrite |
| Token dies again days later | npm retiring bypass-2FA tokens | Re-login; prefer granular tokens with read-write packages |
