  • Works in 2 steps: declare an HTTP mount with… → be included in the active httpApi…
  • An @golemcloud/effect-golem agent must create a public callback URL
  • SKILL.md covers Prerequisites, API, Create, Share, and Await and Mount and Webhook URL, plus 3 more sections

What it does

Golem Add Webhook Effect is an agent skill from golemcloud/golem. Using one-shot webhooks in an Effect-based Golem agent. Use when an @golemcloud/effect-golem agent must create a public callback URL, durably await an external POST, decode its body, or customize its webhook path.

Its SKILL.md is about 2.4k 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 Backend & APIs, covering Webhooks. 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

  • An @golemcloud/effect-golem agent must create a public callback URL
  • Durably await an external POST
  • Decode its body
  • Customize its webhook path

Example prompts

  • “/golem-add-webhook-effect”

Workflow steps

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

  1. declare an HTTP mount with Http.mount(...); and
  2. be included in the active httpApi deployment in golem.yaml.

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 and yaml).

    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 Add Webhook Effect loads about 2.4k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 811 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
~2.4k

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 811 words (~2,352 tokens).

“Webhook.create allocates a Golem promise and mints a temporary public URL for it. Posting to the URL completes the promise; awaiting the handle durably suspends the current invocation without consuming compute until the callback arrives.”
