From the author

Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The Cloudflare platform skill provides a centralized resource for developers building on Cloudflare's edge network. It covers the full ecosystem, including compute (Workers, Pages), storage (KV, D1, R2), AI integration (Workers AI, Agents SDK), networking, and security. The skill emphasizes a retrieval-first approach, directing users to official Cloudflare documentation and configuration schemas to ensure accuracy regarding API signatures, limits, and pricing.

What it does

Provides decision trees to help select the right Cloudflare product for specific compute, storage, or networking needs.
Offers structured references for the Cloudflare Agents SDK, including lifecycle hooks and state management.
Guides users on integrating AI models and vector databases into edge applications.
Outlines methods for managing infrastructure-as-code using Terraform or Pulumi.
Facilitates access to product-specific documentation for security, media, and analytics services.
Maintains a directory of developer tools like Wrangler and Miniflare for local development and testing.

When to use it

When starting a new project on the Cloudflare platform and needing to choose the appropriate architecture.
When implementing stateful AI agents using the Cloudflare Agents SDK.
When configuring edge compute, storage bindings, or networking rules.
When troubleshooting API limits, configuration errors, or deployment issues.
When integrating AI models or vector search into existing edge applications.

Advantages

Consolidates a vast ecosystem into a navigable, task-oriented structure.
Promotes the use of official, up-to-date documentation over potentially stale training data.
Simplifies complex architectural decisions through clear, logic-based decision trees.
Provides specific code patterns for advanced features like Durable Objects and AI agents.
Supports modern infrastructure-as-code workflows for consistent deployments.

Usage examples

“I need to build a stateful AI chat agent on Cloudflare. How do I start?”: The agent will guide you to use the AIChatAgent class from the Agents SDK, explain how to manage message history, and provide a template for integrating AI models.
“Which storage solution should I use for relational data in my Worker?”: The agent will point you to D1 for SQLite-based relational storage or Hyperdrive for connecting to existing Postgres/MySQL databases.
“How do I expose my local development server to the internet via Cloudflare?”: The agent will provide instructions on using Cloudflare Tunnel to securely connect your local service to the Cloudflare edge.

Install

Download the skill as a ZIP:

Unzip it into the cross-client skills folder of your project:

mkdir -p .agents/skills && unzip cloudflare.zip -d .agents/skills

Documentation by Cloudflare

Cloudflare Platform Skill

Consolidated skill for building on the Cloudflare platform. Use decision trees below to find the right product, then load detailed references.

Your knowledge of Cloudflare APIs, types, limits, and pricing may be outdated. Prefer retrieval over pre-training — the references in this skill are starting points, not source of truth.

Retrieval Sources

Fetch the latest information before citing specific numbers, API signatures, or configuration options. Do not rely on baked-in knowledge or these reference files alone.

Source	How to retrieve	Use for
Cloudflare docs	Search `https://developers.cloudflare.com/` directly	Limits, pricing, API reference, compatibility dates/flags
Workers types	`npm pack @cloudflare/workers-types` or check `node_modules`	Type signatures, binding shapes, handler types
Wrangler config schema	`node_modules/wrangler/config-schema.json`	Config fields, binding shapes, allowed values
Product changelogs	`https://developers.cloudflare.com/changelog/`	Recent changes to limits, features, deprecations

When a reference file and the docs disagree, trust the docs. This is especially important for: numeric limits, pricing tiers, type signatures, and configuration options.

Configuration

Basic Setup

Minimal configuration requires only assets.directory:

{
  "name": "my-worker",
  "compatibility_date": "2025-01-01",  // Use current date for new projects
  "assets": {
    "directory": "./dist"
  }
}

Full Configuration Options

{
  "name": "my-worker",
  "main": "src/index.ts",
  "compatibility_date": "2025-01-01",
  "assets": {
    "directory": "./dist",
    "binding": "ASSETS",
    "not_found_handling": "single-page-application",
    "html_handling": "auto-trailing-slash",
    "run_worker_first": ["/api/*", "!/api/docs/*"]
  }
}

Configuration keys:

directory (string, required): Path to assets folder (e.g. ./dist, ./public, ./build)
binding (string, optional): Name to access assets in Worker code (e.g. env.ASSETS). Default: "ASSETS"
not_found_handling (string, optional): Behavior when asset not found
- "single-page-application": Serve /index.html for non-asset paths (default for SPAs)
- "404-page": Serve /404.html if present, otherwise 404
- "none": Return 404 for missing assets
html_handling (string, optional): URL trailing slash behavior
run_worker_first (boolean | string[], optional): Routes that invoke Worker before checking assets

not_found_handling Modes

Mode	Behavior	Use Case
`"single-page-application"`	Serve `/index.html` for non-asset requests	React, Vue, Angular SPAs
`"404-page"`	Serve `/404.html` if exists, else 404	Static sites with custom error page
`"none"`	Return 404 for missing assets	API-first or custom routing

html_handling Modes

Controls trailing slash behavior for HTML files:

Mode	`/page`	`/page/`	Use Case
`"auto-trailing-slash"`	Redirect to `/page/` if `/page/index.html` exists	Serve `/page/index.html`	Default, SEO-friendly
`"force-trailing-slash"`	Always redirect to `/page/`	Serve if exists	Consistent trailing slashes
`"drop-trailing-slash"`	Serve if exists	Redirect to `/page`	Cleaner URLs
`"none"`	No modification	No modification	Custom routing logic

Default: "auto-trailing-slash"

run_worker_first Configuration

Controls which requests invoke Worker before checking assets.

Boolean syntax:

{
  "assets": {
    "run_worker_first": true  // ALL requests invoke Worker
  }
}

Array syntax (recommended):

{
  "assets": {
    "run_worker_first": [
      "/api/*",           // Positive pattern: match API routes
      "/admin/*",         // Match admin routes
      "!/admin/assets/*"  // Negative pattern: exclude admin assets
    ]
  }
}

Pattern rules:

Glob patterns: * (any chars), ** (any path segments)
Negative patterns: Prefix with ! to exclude
Precedence: Negative patterns override positive patterns
Default: false (assets served directly)

Decision guidance:

Use true for API-first apps (few static assets)
Use array patterns for hybrid apps (APIs + static assets)
Use false for static-first sites (minimal dynamic routes)

.assetsignore File

Exclude files from upload using .assetsignore (same syntax as .gitignore):

# .assetsignore
_worker.js
*.map
*.md
node_modules/
.git/

Common patterns:

_worker.js - Exclude Worker code from assets
*.map - Exclude source maps
*.md - Exclude markdown files
Development artifacts

Vite Plugin Integration

For Vite-based projects, use @cloudflare/vite-plugin:

// vite.config.ts
import { defineConfig } from 'vite';
import { cloudflare } from '@cloudflare/vite-plugin';

export default defineConfig({
  plugins: [
    cloudflare({
      assets: {
        directory: './dist',
        binding: 'ASSETS'
      }
    })
  ]
});

Features:

Automatic asset detection during dev
Hot module replacement for assets
Production build integration
Requires: Wrangler 4.0.0+, @cloudflare/vite-plugin 1.0.0+

Key Compatibility Dates

Date	Feature	Impact
`2025-04-01`	Navigation request optimization	SPAs skip Worker for navigation, reducing costs

Use current date for new projects. See Compatibility Dates for full list.

Environment-Specific Configuration

Use wrangler.jsonc environments for different configs:

{
  "name": "my-worker",
  "assets": { "directory": "./dist" },
  "env": {
    "staging": {
      "assets": {
        "not_found_handling": "404-page"
      }
    },
    "production": {
      "assets": {
        "not_found_handling": "single-page-application"
      }
    }
  }
}

Deploy with: wrangler deploy --env staging
