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.

Patterns & Use Cases

Protect API with Schema + JWT

# 1. Upload OpenAPI schema
POST /zones/{zone_id}/api_gateway/user_schemas

# 2. Configure JWT validation
POST /zones/{zone_id}/api_gateway/token_validation
{
  "name": "Auth0",
  "location": {"header": "Authorization"},
  "jwks": "{...}"
}

# 3. Create JWT rule
POST /zones/{zone_id}/api_gateway/jwt_validation_rules

# 4. Set schema validation action
PUT /zones/{zone_id}/api_gateway/settings/schema_validation
{"validation_default_mitigation_action": "block"}

Progressive Rollout

1. Log mode: Observe false positives
   - Schema: Action = Log
   - JWT: Action = Log

2. Block subset: Protect critical endpoints
   - Change specific endpoint actions to Block
   - Monitor firewall events

3. Full enforcement: Block all violations
   - Change default action to Block
   - Handle fallthrough with custom rule

BOLA Detection

Enumeration Detection

Detects sequential resource access (e.g., /users/1, /users/2, /users/3).

// Block BOLA enumeration attempts
(cf.api_gateway.cf-risk-bola-enumeration and http.host eq "api.example.com")
// Action: Block or Challenge

Parameter Pollution

Detects duplicate/excessive parameters in requests.

// Block parameter pollution
(cf.api_gateway.cf-risk-bola-pollution and http.host eq "api.example.com")
// Action: Block

Combined BOLA Protection

// Comprehensive BOLA rule
(cf.api_gateway.cf-risk-bola-enumeration or cf.api_gateway.cf-risk-bola-pollution)
and http.host eq "api.example.com"
// Action: Block

Authentication Posture

Detect Missing Auth

// Log endpoints lacking authentication
(cf.api_gateway.cf-risk-missing-auth and http.host eq "api.example.com")
// Action: Log (for audit)

Detect Mixed Auth

// Alert on inconsistent auth patterns
(cf.api_gateway.cf-risk-mixed-auth and http.host eq "api.example.com")
// Action: Log (review required)

Fallthrough Detection (Shadow APIs)

// WAF Custom Rule
(cf.api_gateway.fallthrough_triggered and http.host eq "api.example.com")
// Action: Log (discover unknown) or Block (strict)

Rate Limiting by User

// Rate Limiting Rule (modern syntax)
(http.host eq "api.example.com" and
 is_jwt_valid(http.request.jwt.payload["{config_id}"][0]))

// Rate: 100 req/60s
// Counting expression: lookup_json_string(http.request.jwt.payload["{config_id}"][0], "sub")

Volumetric Abuse Response

// Detect abnormal traffic spikes
(cf.api_gateway.volumetric_abuse_detected and http.host eq "api.example.com")
// Action: Challenge or Rate Limit

// Combined with rate limiting
(cf.api_gateway.volumetric_abuse_detected or
 cf.threat_score gt 50) and http.host eq "api.example.com"
// Action: JS Challenge

GraphQL Protection

// Block oversized queries
(http.request.uri.path eq "/graphql" and
 cf.api_gateway.graphql_query_size gt 100000)
// Action: Block

// Block deep nested queries
(http.request.uri.path eq "/graphql" and
 cf.api_gateway.graphql_query_depth gt 10)
// Action: Block
