At a glance

Fans out work to multiple durable agents and collects results with Effect structured concurrency.

  • Parallel execution
  • SKILL.md covers Fan Out to Durable Child Agents, Bound Concurrency, Fail-Fast and Partial Results and Child Fibers Are Structured,…, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Bounded concurrency

What it does

Golem Parallel Workers Effect is an agent skill from golemcloud/golem. Fans out work to multiple durable agents and collects results with Effect structured concurrency. Use for parallel execution, fan-out/fan-in, bounded concurrency, child fibers, agent forks, or aggregating remote agent results in an @golemcloud/effect-golem project.

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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

  • Parallel execution
  • Bounded concurrency
  • Aggregating remote agent results in an @golemcloud/effect-golem project

Example prompts

  • “/golem-parallel-workers-effect”

What it can do on your machine

Read from SKILL.md and the folder at commit 2dea6b9. 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 typescript).

    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 Parallel Workers Effect loads about 2.5k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 834 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~74
When it runs · the whole SKILL.md, loaded when a task matches
~2.5k

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 834 words (~2,465 tokens).

“Golem runs invocations to one durable agent instance sequentially. For actual parallel work, send the work to distinct agent instances and compose their typed remote-call Effects with Effect v4 structured-concurrency operators. Do not translate Promise.all, floating promises, or async handlers…”
