npm-release

name	npm-release
description	Use when publishing or preparing to publish an npm package from this repository, especially the Skill Zoo CLI package under packages/cli. Also use when npm publish fails because of duplicate versions, npm authentication, browser authentication, dist-tag propagation, tarball contents, bin entry issues, or workspace/lockfile version mismatches.

npm Release

Overview

Publish an npm package from this repo with local verification, clean package contents, and npm browser authentication. For Skill Zoo today, the npm package is the CLI package in packages/cli; the workspace root is private and is not the package to publish.

Announce at start: "I'm using the npm-release skill to publish the npm package."

Privacy Guardrails

Do not write private npm account details into repo files, skill files, logs, release notes, or final summaries. This includes npm usernames, email addresses, authentication secrets, browser auth URLs, auth IDs, tokens, local npm debug log paths, and machine-specific temporary directories.

It is fine to state generic facts such as "npm required browser authentication" or "the authenticated owner account was permitted." Do not paste the actual authentication URL into a committed file. If a URL is needed transiently, use it only to complete the live browser flow.

When to Use

Use this skill when:

• The user says "publish npm", "release the npm package", "npm publish", "发 npm", or "发布 npm 包"
• The package is in a workspace and you need to identify the real publishable package
• npm publish fails with duplicate version, npm authentication, owner, tarball, or bin problems
• The user asks whether a package is ready for npm publication
• A release bump needs to update package metadata and lockfile state consistently

Do not use this skill for:

• Desktop app GitHub Releases or Homebrew cask releases; use app-release
• Tauri updater implementation; use tauri-updater
• Publishing a package you have not locally verified

Package Target

For this repo, start with the CLI package:

cd packages/cli

Confirm the root package is not the target:

node -e "console.log(require('./package.json').private)"
node -e "const p=require('./packages/cli/package.json'); console.log(p.name, p.version, p.bin)"

If the target changes in the future, publish from the directory whose package.json has the public npm name, bin, files, scripts.prepack, and production dependencies.

Preflight

Check the repo instructions and current working tree first:

test -f CLAUDE.md && sed -n '1,220p' CLAUDE.md
test -f AGENTS.md && sed -n '1,220p' AGENTS.md
git status --short

Do not revert or overwrite unrelated changes. If publish-relevant files already have user edits, inspect them and work with the current state.

Check npm registry state before changing versions:

cd packages/cli
npm view skill-zoo version dist-tags --json
npm view skill-zoo versions --json
npm whoami
npm owner ls skill-zoo

If the local version already exists on npm, explain that npm versions are immutable and ask the user which new version to publish before changing files. Do not choose or apply the release version silently.

Version Bump

For the Skill Zoo CLI package, update:

• packages/cli/package.json
• bun.lock workspace entry for packages/cli

Ask the user to confirm the exact version before editing release files. If they ask for a recommendation, propose the smallest sensible semver bump and explain why, then wait for confirmation before applying it.

After bumping, search for hardcoded old versions that should follow the package version:

OLD_VERSION=<previous-version>
rg "\"version\": \"${OLD_VERSION}\"|skill-zoo-cli@${OLD_VERSION}|skill-zoo@${OLD_VERSION}" packages/cli bun.lock

Tests should generally depend on CLI_VERSION rather than hardcoding a release version. This prevents a release bump from breaking tests only because an expected metadata string changed.

Required Verification

Run these from packages/cli after any version or release-related change:

npm run typecheck
npm test
npm run build
npm publish --dry-run

The dry-run must show the expected version and tarball contents. For this CLI, expected package contents are small and should normally be:

README.md
dist/index.d.ts
dist/index.js
package.json
wui/app.js
wui/index.html
wui/styles.css

If extra source, test, repo, log, or private files appear, fix the files whitelist or ignore rules before publishing.

CLI Package Checks

Before publishing a CLI package, verify the executable path matches bin and can start from the built artifact:

cd ../..
sed -n '1,20p' packages/cli/src/index.ts
sed -n '1,20p' packages/cli/dist/index.js
ls -l packages/cli/dist/index.js packages/cli/dist/index.d.ts
node packages/cli/dist/index.js --version
node packages/cli/dist/index.js --help | sed -n '1,120p'

For higher confidence, install the actual tarball in a temporary project and run both binary names:

cd packages/cli
tmp="$(mktemp -d)"
npm pack --pack-destination "$tmp"
mkdir "$tmp/install"
cd "$tmp/install"
npm init -y >/dev/null
npm install "$tmp"/skill-zoo-*.tgz
./node_modules/.bin/skill-zoo --version
./node_modules/.bin/szoo --help | sed -n '1,40p'

Do not commit generated tarballs or temporary install directories.

Publishing

Publish only after typecheck, tests, build, and npm publish --dry-run pass. Before the real npm publish, summarize the package name, version, dist tag, and tarball contents, then ask the user for explicit confirmation.

Log in first. --auth-type=web authenticates npm login, not npm publish — publishing while unauthenticated fails with a 404 that masks the real cause. Ensure a valid token exists (see "Non-TTY browser authentication") before publishing, and drop --auth-type=web from the publish command.

Working directory does not persist between tool calls. Always include cd <path> in the command itself — never assume a previous cd still applies. When publishing from a workspace sub-package, use an absolute cd prefix:

cd /path/to/repo/packages/cli && npm publish --registry https://registry.npmjs.org/

Preferred command after user confirmation:

cd packages/cli
npm publish --registry https://registry.npmjs.org/

If the machine's default registry is a read-only mirror (e.g. registry.npmmirror.com), the explicit --registry https://registry.npmjs.org/ is required — mirrors do not accept publishes.

Non-TTY browser authentication

Two different steps need browser auth, and npm handles them differently in agent environments (Claude Code, Cowork, CI):

Login — npm login --auth-type=web prints the full https://www.npmjs.com/login?next=/login/cli/<id> URL even without a TTY, so no script wrapper is needed. Just open the printed "Login at:" URL:

npm login --auth-type=web --registry https://registry.npmjs.org/
# then open the printed "Login at:" URL in the user's browser

Publish 2FA (EOTP) — when the account requires 2FA for publishing, npm publish fails with EOTP and prints its auth URL redacted as *** (https://www.npmjs.com/auth/cli/***). Only this step needs a real TTY to reveal the URL. Use script -q /dev/null, and feed it a leading newline because npm's TTY prompt ("Press ENTER to open in the browser...") otherwise blocks before it polls for authentication:

printf '\n' | script -q /dev/null npm publish --registry https://registry.npmjs.org/ 2>&1 &
sleep 8
# grep the real "Authenticate your account at:" URL from output, then:
open "https://www.npmjs.com/auth/cli/<id>"

Extract the URL, open it in the user's browser, and keep the background process alive while they authenticate. If script is unavailable (e.g. a sandbox blocks pty allocation), fall back to --otp <6-digit TOTP>.

Success looks like:

+ skill-zoo@X.Y.Z

Post-Publish Verification

Registry reads can briefly lag after publish. Verify both the specific version and the dist tag:

npm view skill-zoo@X.Y.Z version dist.tarball time --json
npm dist-tag ls skill-zoo
npm view skill-zoo versions --json

Treat npm dist-tag ls as the clearer signal for latest when npm view skill-zoo version appears stale immediately after publication.

The final user summary should include:

• Published package and version
• Verification commands that passed
• Registry confirmation, including latest if applicable
• Local files changed and still uncommitted

Do not include private account identifiers, browser auth URLs, npm auth IDs, authentication secrets, debug log paths, or temporary directory paths in the final summary.

Failure Handling

Failure	Cause	Response
You cannot publish over the previously published versions	Local version already exists on npm	Ask the user to confirm the new version, then bump packages/cli/package.json, sync lockfile, and rerun checks
npm publish returns 404 / "do not have permission"	Not logged in — --auth-type=web does not authenticate at publish time	Run npm login --auth-type=web --registry https://registry.npmjs.org/ first, then publish
npm error code EOTP	Account requires 2FA for publishing	Either get the user's 6-digit TOTP and pass --otp <code>, or complete the browser web-OTP flow (see "Non-TTY browser authentication")
Browser auth URL is ***	npm redacted the publish OTP URL in non-TTY output	Wrap the publish in script -q /dev/null with a leading newline (see "Non-TTY browser authentication"), extract the real URL, then open it
npm errors with EPERM on the ~/.npm cache	Cache dir has root-owned files from an old npm bug	Run sudo chown -R $(id -u):$(id -g) ~/.npm, or use a temp cache via --cache /tmp/xxx
npm login fails writing ~/.npmrc (EPERM)	Home dir not writable from the agent sandbox	Log in with --userconfig /tmp/xxx.npmrc and pass the same --userconfig to npm publish; delete the file afterward
Tests fail after version bump	Hardcoded expected version	Prefer asserting against CLI_VERSION
Dry-run includes unexpected files	Bad files whitelist or generated artifacts	Fix package manifest before publishing
Bin command fails after tarball install	bin path, shebang, executable bit, or bundle issue	Fix before publishing and rerun tarball install check
latest appears stale after success

Command Sequence

Use this as the default release skeleton for skill-zoo CLI:

cd /path/to/repo
git status --short
npm view skill-zoo version dist-tags --json

# ask the user to confirm the exact version, then bump packages/cli/package.json and bun.lock if needed

# log in first (prints the full URL even non-TTY); skip if a valid token already exists
npm login --auth-type=web --registry https://registry.npmjs.org/
# open the printed "Login at:" URL, wait for the user to authenticate

cd /path/to/repo/packages/cli
npm run typecheck
npm test
npm run build
npm publish --dry-run

# summarize dry-run results and ask the user to confirm the real publish
# if the account requires 2FA, the publish OTP URL is redacted as *** — wrap with script:
printf '\n' | script -q /dev/null npm publish --registry https://registry.npmjs.org/ 2>&1 &
# extract the "Authenticate your account at:" URL, open in browser, wait for user

npm view skill-zoo@X.Y.Z version dist.tarball time --json
npm dist-tag ls skill-zoo
npm view skill-zoo versions --json

Keep the package release commit separate from unrelated feature work when possible. If the user's working tree already contains feature changes intended for the release, report them clearly instead of hiding them inside the release summary.
