Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/steipete/agent-scripts --skill npm
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads npm automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

npm

Use for npm registry/account tasks: npm whoami, package availability, package reservation, publish, org checks, and auth debugging.

Auth

  • Use one-password first for secret rules.
  • Never run op directly in the shell tool.
  • Primary item: npm Registry - steipete - Release Automation in Molty.
  • Default to OP_SERVICE_ACCOUNT_TOKEN; no desktop unlock. The item carries the working registry session (registry_token) plus username/password/TOTP fallback.
  • Desktop npmjs fallback is explicit only: pass --account my.1password.com when Molty is unavailable and the user wants the fallback. Explicit release/publish requests are consent for its unlock prompt.
  • Stop and ask if the item is missing, the account/vault is ambiguous, credentials are malformed, npm denies package access, or the requested package/version does not match the repo release target.
  • Run npm auth work inside one task window of the shared op-work tmux session (clawdbot-op.sock; see one-password). Reuse the window on failure; kill it when the npm task is done. Never mint an npm-specific socket or session.
  • Keep npm auth in a temp npmrc; delete it after the command.
  • All helpers share scripts/npm-auth.sh: stored registry_token session first, then scripts/npm-auth-login.mjs registry login with a fresh six-digit OTP; successful fallback sessions are cached back to the same item. Do not hand-roll field extraction, registry login, or cache writes.
  • Installed skill directory symlinks are supported. Shell entrypoints resolve physical siblings; sourced npm-auth.sh owns NPM_AUTH_SCRIPT_DIR without changing the caller's SCRIPT_DIR or working directory. Node helpers also support file symlinks, including --preserve-symlinks-main.
  • Credential selection prefers canonical field id, then purpose, then a unique label; duplicate label-only matches are rejected (legacy npmjs may retain same-label fields).
  • For ad-hoc authenticated registry commands, use scripts/npm-service.sh -- <npm args...>; use publish-package.sh for a local package.
  • npm 11 prompt piping is brittle; avoid printf ... | npm login --auth-type=legacy.
  • Avoid expect for npm login unless necessary; logs can echo prompts and are easy to get wrong.
  • Prefer the helper's registry API login path (npm-profile loginCouch) for automation.
  • If auth shape is ambiguous or npm whoami fails, stop and ask for the exact field label / credential fix. Do not probe more 1Password items or open another tmux window/session.

Package Publishing

From the package root, inside the same auth tmux window:

/Users/steipete/Projects/agent-scripts/skills/npm/scripts/publish-package.sh

The helper verifies identity, refuses an existing package version, publishes with a fresh OTP, retries one expired OTP, verifies registry visibility with the same temporary npmrc (including restricted packages), and cleans auth files.

Package Reservation

Use scripts/reserve-packages.sh from inside the same tmux window:

/Users/steipete/Projects/agent-scripts/skills/npm/scripts/reserve-packages.sh package-one package-two

What it does:

  • reads the Molty release-automation item once via op
  • reuses the stored registry session or creates one from username/password/TOTP
  • publishes 0.0.0 placeholder packages with a generic README
  • continues after per-package publish failures
  • redacts tokens/OTP in logs
  • cleans temp npmrc/work dirs

Notes:

  • npm may reject names as too similar to already-published names. Treat that as a registry policy result, not an auth failure.
  • npm CLI prompt piping is brittle on npm 11. Prefer the helper’s registry API login path over scripted npm login.
  • For scoped packages, npm view can lag/404 even when the package exists. Check npm access get status <pkg>; public or a publish failure saying previously published versions means the name is reserved.

Offline Regression Tests

From the repo root; synthetic fixtures only, no real 1Password/npm auth. Always use an empty environment (the shell mock checks its environment for token leaks):

test_home="$(mktemp -d)"
(
  set -e
  trap 'rm -rf "$test_home"' EXIT
  env -i HOME="$test_home" PATH="$PATH" node --test skills/npm/scripts/*.test.mjs </dev/null
  env -i HOME="$test_home" PATH="$PATH" /bin/bash skills/npm/scripts/npm-auth.test.sh </dev/null
)

FAQ

What does the npm skill do?

npm registry ops: login, whoami, names, publish; 1Password tmux.

How do I install npm?

Run npx skills add https://github.com/steipete/agent-scripts --skill npm in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/npm/ (personal) or .claude/skills/npm/ (project).

Which AI agents can use npm?

Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.

Is npm safe to install?

No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.

Who maintains npm?
