At a glance

Understanding and parsing Golem CLI structured output. An agent skill from golemcloud/golem.

  • Using --format json
  • SKILL.md covers Formats, Secret And Masking Behavior, $type Discriminator and Discover Output Schemas, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Discovering $type schemas with golem output-schema

What it does

Golem CLI Structured Output is an agent skill from golemcloud/golem. Understanding and parsing Golem CLI structured output. Use when using --format json, --format yaml, --format toon, discovering $type schemas with golem output-schema, or writing agents/tools that parse CLI output.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Structured output and tool calling. 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

  • Using --format json
  • Discovering $type schemas with golem output-schema
  • Writing agents/tools that parse CLI output

Example prompts

  • “/golem-cli-structured-output”

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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and json).

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

  • Network

    No URLs in SKILL.md.

    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 CLI Structured Output loads about 1.6k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 746 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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 746 words (~1,566 tokens).

“Both golem and golem-cli can emit machine-readable structured output. Use this skill when building scripts, coding agents, test harnesses, or tools that parse CLI output.”
