At a glance

Add a new npm package dependency to a TypeScript Golem project.

  • Works in 3 steps: Install the package → Build to verify → If the build or runtime fails
  • The user asks to add a library
  • SKILL.md covers Important constraints, Steps, Already available packages and HTTP requests, plus 1 more section
  • Calls npm and npx

What it does

Golem Add npm Package is an agent skill from golemcloud/golem. Add a new npm package dependency to a TypeScript Golem project. Use when the user asks to add a library, package, or dependency.

Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with npm, TypeScript, WebAssembly and Node.js. The repository describes itself as: Golem Cloud is the agent-native platform for building AI agents and distributed applications that never lose state, never duplicate work, and never require you to build…

When your agent uses it

  • The user asks to add a library

Example prompts

  • “/golem-add-npm-package”

Requirements

  • Node.js

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Install the package
  2. Build to verify
  3. If the build or runtime fails

What it can do on your machine

Read from SKILL.md and the folder at commit efc90f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Golem Add npm Package loads about 902 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 386 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~902

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 386 words (~902 tokens).

“runtime. It cannot create host processes or run a general shell. node:cluster, node:http2, and node:worker_threads remain unsupported or stubbed.”
