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.

Common Errors

"Logs not appearing"

Cause: Observability disabled, Worker not redeployed, no traffic, low sampling rate, or log size exceeds 256 KB Solution:

# Verify config
cat wrangler.jsonc | jq '.observability'

# Check deployment
wrangler deployments list <WORKER_NAME>

# Test with curl
curl https://your-worker.workers.dev

Ensure observability.enabled = true, redeploy Worker, check head_sampling_rate, verify traffic

"Traces not being captured"

Cause: Traces not enabled, incorrect sampling rate, Worker not redeployed, or destination unavailable Solution:

// Temporarily set to 100% sampling for debugging
{
  "observability": {
    "enabled": true,
    "head_sampling_rate": 1.0,
    "traces": {
      "enabled": true
    }
  }
}

Ensure observability.traces.enabled = true, set head_sampling_rate to 1.0 for testing, redeploy, check destination status

Limits

Resource/Limit	Value	Notes
Max log size	256 KB	Logs exceeding this are truncated
Default sampling rate	1.0 (100%)	Reduce for high-traffic Workers
Max destinations	Varies by plan	Check dashboard
Trace context propagation	100 spans max	Deep call chains may lose spans
Analytics Engine write rate	25 writes/request	Excess writes dropped silently

Performance Gotchas

Spectre Mitigation Timing

Problem: Date.now() and performance.now() have reduced precision (coarsened to 100μs) Cause: Spectre vulnerability mitigation in V8 Solution: Accept reduced precision or use Workers Traces for accurate timing

// Date.now() is coarsened - trace spans are accurate
export default {
  async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise<Response> {
    // For user-facing timing, Date.now() is fine

Analytics Engine _sample_interval Aggregation

Problem: Queries return incorrect totals when not multiplying by _sample_interval Cause: Analytics Engine stores sampled data points, each representing multiple events Solution: Always multiply counts/sums by _sample_interval in aggregations

-- WRONG: Undercounts actual events
SELECT blob1 AS customer_id, COUNT(*) AS total_calls
FROM api_usage GROUP BY customer_id;

-- CORRECT: Accounts for sampling
SELECT blob1 AS customer_id, SUM(_sample_interval) AS total_calls
FROM api_usage GROUP BY customer_id;

Trace Context Propagation Limits

Problem: Deep call chains lose trace context after 100 spans Cause: Cloudflare limits trace depth to prevent performance impact Solution: Design for flatter architectures or use custom correlation IDs for deep chains

// For deep call chains, add custom correlation ID
const correlationId = crypto.randomUUID();
console.log({ correlationId, event: 'request_start' });

// Pass correlationId through headers to downstream services
await fetch('https://api.example.com', {
  headers: { 'X-Correlation-ID': correlationId }
});
