At a glance

Creating and reconnecting multiple Effect-based agent instances with identical agent id fields.

  • NewPhantom/getPhantom
  • SKILL.md covers Typed Client API, Stateful Multi-Instance Example, Save and Reconnect to a Phantom and Ephemeral and HTTP Cases, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Independent per-instance state with @golemcloud/effect-golem

What it does

Golem Multi Instance Agent Effect is an agent skill from golemcloud/golem. Creating and reconnecting multiple Effect-based agent instances with identical agent id fields. Use for phantom agents, newPhantom/getPhantom, phantom IDs, or independent per-instance state with @golemcloud/effect-golem.

Its SKILL.md is about 1.8k 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

  • NewPhantom/getPhantom
  • Independent per-instance state with @golemcloud/effect-golem

Example prompts

  • “/golem-multi-instance-agent-effect”

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 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 Multi Instance Agent Effect loads about 1.8k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 530 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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 530 words (~1,826 tokens).

“Phantom agents give otherwise identical agent id fields an additional UUID identity. A regular durable agent is addressed only by its agent id fields, so repeated client.get calls reach the same instance. Each client.newPhantom call generates a fresh UUID and…”
