cloudflare-workflows

cloudflare-workflows is a skill for Claude Code, Codex from secondsky/claude-skills. It costs 37 tokens per session (4,055 once invoked), scanned A, original, MIT.

A reference and working guide for Cloudflare Workflows, a service for running multi-step jobs with retries and saved progress. It explains how to create, configure, test, and troubleshoot these workflows.

In plain words
What is it for?
Use it when building jobs with several steps, delays, retries, or saved state in a Cloudflare Worker.
Why use it?
It gives developers the concepts and examples needed to build workflows without first learning the service from scattered documentation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cloudflare-workflows scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 7 executable files (templates/basic-workflow.ts, templates/circuit-breaker-workflow.ts, templates/parallel-execution-workflow.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Cloudflare Workflows

Status: Production Ready ✅ | Last Verified: 2025-12-27 | Version: 3.0.0

Quick Start (10 Minutes)

1. Create a Workflow

Use the Cloudflare Workflows starter template:

npm create cloudflare@latest my-workflow -- --template cloudflare/workflows-starter --git --deploy false
cd my-workflow

What you get:

  • WorkflowEntrypoint class template
  • Worker to trigger workflows
  • Complete wrangler.jsonc configuration

2. Basic Workflow Structure

src/index.ts:

import { WorkflowEntrypoint, WorkflowStep, WorkflowEvent } from 'cloudflare:workers';

type Env = {
  MY_WORKFLOW: Workflow;
};

type Params = {
  userId: string;
  email: string;
};

export class MyWorkflow extends WorkflowEntrypoint<Env, Params> {
  async run(event: WorkflowEvent<Params>, step: WorkflowStep) {
    const { userId, email } = event.payload;

    // Step 1: Do work with automatic retries
    const result = await step.do('process user', async () => {
      return { processed: true, userId };
    });

    // Step 2: Wait before next step
    await step.sleep('wait 1 hour', '1 hour');

    // Step 3: Continue workflow
    await step.do('send email', async () => {
      return { sent: true, email };
    });

    return { completed: true, userId };
  }
}

// Worker to trigger workflow
export default {
  async fetch(req: Request, env: Env): Promise<Response> {
    const instance = await env.MY_WORKFLOW.create({
      params: { userId: '123', email: '[email protected]' }
    });

    return Response.json({
      id: instance.id,
      status: await instance.status()
    });
  }
};

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
