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 publishfails 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:
bashcd packages/cli
Confirm the root package is not the target:
bashnode -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:
bashsed -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:
bashcd 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.jsonbun.lockworkspace entry forpackages/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:
bashOLD_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:
bashnpm 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:
textREADME.md dist/index.js package.json wui/app.js wui/index.html wui/styles.css
There is deliberately no dist/index.d.ts. The CLI entry (packages/cli/src/index.ts)
is a shebang script that calls runCli() and exports nothing, so the declaration file
tsup's --dts emitted contained only the shebang line, which means it was a type contract with no types.
It was also unreachable: the package declares bin and no main/exports/types, so a
consumer's import ... from "skill-zoo" fails with TS2307 before the file is ever read
(wiring up types instead yields TS2306: is not a module). Rather than keep a
misleading empty file, the build no longer emits declarations. If the CLI ever grows a
programmatic API, re-add declarations and the types/exports wiring together.
If extra source, test, repo, log, or private files appear, fix the files whitelist or ignore rules before publishing.
Mirror CI's steps, not just the package's. The bump touches packages/cli/package.json and bun.lock, and build.yml checks those from the workspace root with steps the package-level list above never runs. Run them locally after the bump too:
bashcd ../.. bun run lint && bun run format:check && bun run typecheck && bun run test bun run cli:typecheck
When the workflow changes, re-derive the list from it rather than trusting this skill: grep -nE '^\s+-?\s*run:' .github/workflows/build.yml. A step CI runs that the local list omits is a blind spot. On 2026-10-22, adr-kit's 0.24.0 passed every local check and went red on the one CI step that was not in its skill.
Fifth gate: green CI on the pushed release commit. The local checks run on one machine; CI runs on every platform the release must work on. Commit the release, push, and wait for the runs before publishing. Watch by workflow name and the pushed commit's SHA. The command gh run list --limit 1 returns whichever run started last, which can be site (it also runs on a push that touches site/) or a run for another commit, and then reports green while build fails:
bashgit push origin main sha="$(git rev-parse HEAD)" for wf in build site; do id="$(gh run list --workflow "$wf" --limit 5 --json databaseId,headSha \ --jq ".[] | select(.headSha==\"$sha\") | .databaseId" | head -1)" [ -n "$id" ] && gh run watch "$id" --exit-status done
Code CI has not seen does not publish. On 2026-10-13 the release-adjacent chore: update version.json for v0.3.52 commit landed on main with a failing Build. If the release commit's run fails, fix forward in a new commit, push, and wait again; never amend or force-push a pushed release commit.
CLI Package Checks
Before publishing a CLI package, verify the executable path matches bin and can start from the built artifact:
bashcd ../.. sed -n '1,20p' packages/cli/src/index.ts sed -n '1,20p' packages/cli/dist/index.js ls -l packages/cli/dist/index.js node packages/cli/dist/index.js --version node packages/cli/dist/index.js --help | sed -n '1,120p'
For higher confidence, install the actual tarball in a temporary project and run both binary names:
bashcd packages/cli tmp="$(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, npm publish --dry-run pass, and the pushed release commit's CI run is green. 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:
bashcd /path/to/repo/packages/cli && npm publish --registry https://registry.npmjs.org/
Preferred command after user confirmation:
bashcd 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 because 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):
Capture auth URLs from raw output only. Run both commands so their full output lands in a file (a background task's output file), then grep that file for the URL. Never pipe npm login or npm publish themselves through grep, sed, tail, or any other filter: npm goes quiet while it polls for the browser authorization, and a filter's block buffer then holds the URL line indefinitely, so the attempt has to be killed and rerun raw.
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:
bashnpm 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:
bashprintf '\n' | script -q /dev/null npm publish --registry https://registry.npmjs.org/ 2>&1 # background task, RAW output # grep the background output FILE for the real "https://www.npmjs.com/auth/cli/<id>" # URL. Never pipe the publish command itself through a filter: 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:
text+ skill-zoo@X.Y.Z
Post-Publish Verification
Registry reads can lag after publish. About a minute is typical, and adr-kit saw 130 seconds on 2026-10-22 after a PUT 202 with the notice "Your package is being processed and may take a few minutes to become available". Poll the exact version every 10 seconds for up to three minutes before concluding the publish failed, then verify both the specific version and the dist tag:
bashfor i in $(seq 1 18); do npm view skill-zoo@X.Y.Z version 2>/dev/null | grep -q 'X.Y.Z' && break sleep 10 done 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
latestif 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, because --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 |
| Auth URL never surfaces while "Authenticate your account at:" did | Publish output was piped through grep or another filter; npm's quiet auth polling left the URL in the filter's block buffer | Kill the attempt because nothing publishes without the browser flow, then rerun with raw output and grep the output file |
| A platform test failure appears in CI after pushing the release commit | Code reached the release without ever passing CI | Fix, commit, push, wait for green; publish only commits whose CI run is green |
Every local check passed but CI failed on a step such as lint, format:check, or root typecheck | The skill's package-level checks do not cover build.yml's workspace-root steps, which also see the bumped package.json and bun.lock | Run the root bun run lint && bun run format:check && bun run typecheck && bun run test after the bump; re-derive the step list from the workflow when it changes |
gh run watch reported green but build failed | gh run list --limit 1 picked the site workflow or a run for another commit | Watch runs by workflow name and the pushed commit's SHA, as in Required Verification |
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 | Registry/cache delay | Query npm dist-tag ls and the exact name@version |
Command Sequence
Use this as the default release skeleton for skill-zoo CLI:
bashcd /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 # mirror build.yml's workspace-root steps; the bump touched package.json and bun.lock cd /path/to/repo bun run lint && bun run format:check && bun run typecheck && bun run test bun run cli:typecheck # commit the release bump, push, and wait for CI because green runs are a publish precondition git push origin main sha="$(git rev-parse HEAD)" for wf in build site; do id="$(gh run list --workflow "$wf" --limit 5 --json databaseId,headSha \ --jq ".[] | select(.headSha==\"$sha\") | .databaseId" | head -1)" [ -n "$id" ] && gh run watch "$id" --exit-status done # 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 ***, so wrap with script: printf '\n' | script -q /dev/null npm publish --registry https://registry.npmjs.org/ 2>&1 # background task, RAW output # grep the output file for 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.
