What it does

Golem Build is an agent skill from golemcloud/golem. Building a Golem application. Use when asked to build a Golem project, compile components to WASM, or troubleshoot build errors.

Its SKILL.md is about 1.2k 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 WebAssembly, Rust and TypeScript. 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

  • Asked to build a Golem project
  • Compile components to WASM
  • Troubleshoot build errors

Example prompts

  • “/golem-build”

Requirements

  • Node.js

Workflow steps

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

  1. Check — verifies that required build tools are installed (e.g., cargo for Rust, npm/node for TypeScript).
  2. Build — executes the build commands defined in golem.yaml for each component. These commands are language-specific
  3. Add Metadata — embeds component name and version into the output WASM binary.
  4. Generate Bridge — generates bridge SDK code if the project uses inter-component communication.

What it can do on your machine

Read from SKILL.md and the folder at commit c6a3029. 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:

    • cargo
    • npm

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

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    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 Build loads about 1.2k tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 496 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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 496 words (~1,175 tokens).

“Both golem and golem-cli can be used — all commands below work with either binary.”
