What it does
Golem Parallel Workers Scala is an agent skill from golemcloud/golem. Fan out work to multiple parallel agents and collect results in a Scala Golem project. Use when the user asks about parallel execution, fan-out/fan-in, spawning child agents for parallel work, forking, or aggregating results from multiple agents.
Its SKILL.md is about 1.9k 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 Agent Workflows, covering Subagents. 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 about parallel execution
- Spawning child agents for parallel work
- Aggregating results from multiple agents
Example prompts
- “/golem-parallel-workers-scala”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Child agents via codegen-generated XClient.get(id) — spawn separate agent instances, dispatch work, and collect results
- HostApi.fork() — clone the current agent at the current execution point for lightweight parallel execution
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 scala).
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 Scala loads about 1.9k tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 323 words of instructions outside code blocks.
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 323 words (~1,851 tokens).
“Golem agents process invocations sequentially — a single agent cannot run work in parallel. To execute work concurrently, distribute it across multiple agent instances. This skill covers two approaches:”
