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.

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.

SourceHow to retrieveUse for
Cloudflare docsSearch https://developers.cloudflare.com/ directlyLimits, pricing, API reference, compatibility dates/flags
Workers typesnpm pack @cloudflare/workers-types or check node_modulesType signatures, binding shapes, handler types
Wrangler config schemanode_modules/wrangler/config-schema.jsonConfig fields, binding shapes, allowed values
Product changelogshttps://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.

Gotchas & Troubleshooting

Rate Limits & 429 Errors

Actual Limits:

  • 1200 requests / 5 minutes per user/token (global)

  • 200 requests / second per IP address

  • GraphQL: 320 / 5 minutes (cost-based)

SDK Behavior:

  • Auto-retry with exponential backoff (default 2 retries, Go: 10)

  • Respects Retry-After header

  • Throws RateLimitError after exhausting retries

Solution:

// Increase retries for rate-limit-heavy workflows
const client = new Cloudflare({ maxRetries: 5 });

// Add application-level throttling
import pLimit from 'p-limit';
const limit = pLimit(10); // Max 10 concurrent requests

SDK-Specific Issues

Go: Required Field Wrapper

Problem: Go SDK requires cloudflare.F() wrapper for optional fields.

// ❌ WRONG - Won't compile or send field
client.Zones.New(ctx, cloudflare.ZoneNewParams{
    Name: "example.com",
})

// ✅ CORRECT
client.Zones.New(ctx, cloudflare.ZoneNewParams{
    Name: cloudflare.F("example.com"),
    Account: cloudflare.F(cloudflare.ZoneNewParamsAccount{
        ID: cloudflare.F("account-id"),
    }),
})

Why: Distinguishes between zero value, null, and omitted fields.

Python: Async vs Sync Clients

Problem: Using sync client in async context or vice versa.

# ❌ WRONG - Can't await sync client
from cloudflare import Cloudflare
client = Cloudflare()
await client.zones.list()  # TypeError

# ✅ CORRECT - Use AsyncCloudflare
from cloudflare import AsyncCloudflare
client = AsyncCloudflare()
await client.zones.list()

Token Permission Errors (403)

Problem: API returns 403 Forbidden despite valid token.

Cause: Token lacks required permissions (scope).

Scopes Required:

OperationRequired Scope
List zonesZone:Read (zone-level or account-level)
Create zoneZone:Edit (account-level)
Edit DNSDNS:Edit (zone-level)
Deploy WorkerWorkers Script:Edit (account-level)
Read KVWorkers KV Storage:Read
Write KVWorkers KV Storage:Edit

Solution: Re-create token with correct permissions in Dashboard → My Profile → API Tokens.

Pagination Truncation

Problem: Only getting first 20 results (default page size).

Solution: Use auto-pagination iterators.

// ❌ WRONG - Only first page (20 items)
const page = await client.zones.list();

// ✅ CORRECT - All results
const zones = [];
for await (const zone of client.zones.list()) {
  zones.push(zone);
}

Workers Subrequests

Problem: Rate limit hit faster than expected in Workers.

Cause: Workers subrequests count as separate API calls.

Solution: Use bindings instead of REST API in Workers (see ../bindings/).

// ❌ WRONG - REST API in Workers (counts against rate limit)
const client = new Cloudflare({ apiToken: env.CLOUDFLARE_API_TOKEN });
const zones = await client.zones.list();

// ✅ CORRECT - Use bindings (no rate limit)
// Access via env.MY_BINDING

Authentication Errors (401)

Problem: "Authentication failed" or "Invalid token"

Causes:

  • Token expired

  • Token deleted/revoked

  • Token not set in environment

  • Wrong token format

Solution:

// Verify token is set
if (!process.env.CLOUDFLARE_API_TOKEN) {
  throw new Error('CLOUDFLARE_API_TOKEN not set');
}

// Test token
const user = await client.user.tokens.verify();
console.log('Token valid:', user.status);

Timeout Errors

Problem: Request times out (default 60s).

Cause: Large operations (bulk DNS, zone transfers).

Solution: Increase timeout or split operations.

// Increase timeout
const client = new Cloudflare({
  timeout: 300000, // 5 minutes
});

// Or split operations
const batchSize = 100;
for (let i = 0; i < records.length; i += batchSize) {
  const batch = records.slice(i, i + batchSize);
  await processBatch(batch);
}

Zone Not Found (404)

Problem: Zone ID valid but returns 404.

Causes:

  • Zone not in account associated with token

  • Zone deleted

  • Wrong zone ID format

Solution:

// List all zones to find correct ID
for await (const zone of client.zones.list()) {
  console.log(zone.id, zone.name);
}

Limits Reference

Resource/LimitValueNotes
API rate limit1200/5minPer user/token
IP rate limit200/secPer IP
GraphQL rate limit320/5minCost-based
Parallel requests (recommended)< 10Avoid overwhelming API
Default page size20Use auto-pagination
Max page size50Some endpoints

Best Practices

Security:

  • Never commit tokens

  • Use minimal permissions

  • Rotate tokens regularly

  • Set token expiration

Performance:

  • Batch operations

  • Use pagination wisely

  • Cache responses

  • Handle rate limits

Code Organization:

// Create reusable client instance
export const cfClient = new Cloudflare({
  apiToken: process.env.CLOUDFLARE_API_TOKEN,
  maxRetries: 5,
});

// Wrap common operations
export async function getZoneDetails(zoneId: string) {
  return await cfClient.zones.get({ zone_id: zoneId });
}
