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.

DDoS Gotchas

Common Errors

"False positives blocking legitimate traffic"

Cause: Sensitivity too high, wrong action, or missing exceptions Solution:

Lower sensitivity for specific rule/category
Use log action first to validate (Enterprise Advanced)
Add exception with custom expression (e.g., allowlist IPs)
Query flagged requests via GraphQL Analytics API to identify patterns

"Attacks getting through"

Cause: Sensitivity too low or wrong action Solution: Increase to default sensitivity and use block action:

const config = {
  rules: [{
    expression: "true",
    action: "execute",
    action_parameters: { id: managedRulesetId, overrides: { sensitivity_level: "default", action: "block" } },
  }],
};

"Adaptive rules not working"

Cause: Insufficient traffic history (needs 7 days) Solution: Wait for baseline to establish, check dashboard for adaptive rule status

"Zone override ignored"

Cause: Account overrides conflict with zone overrides Solution: Configure at zone level OR remove zone overrides to use account-level

"Log action not available"

Cause: Not on Enterprise Advanced DDoS plan Solution: Use managed_challenge with low sensitivity for testing

"Rule limit exceeded"

Cause: Too many override rules (Free/Pro/Business: 1, Enterprise Advanced: 10) Solution: Combine conditions in single expression using and/or

"Cannot override rule"

Cause: Rule is read-only Solution: Check API response for read-only indicator, use different rule

"Cannot disable DDoS protection"

Cause: DDoS managed rulesets cannot be fully disabled (always-on protection) Solution: Set sensitivity_level: "eoff" for minimal mitigation

"Expression not allowed"

Cause: Custom expressions require Enterprise Advanced plan Solution: Use expression: "true" for all traffic, or upgrade plan

"Managed ruleset not found"

Cause: Zone/account doesn't have DDoS managed ruleset, or incorrect phase Solution: Verify ruleset exists via client.rulesets.list(), check phase name (ddos_l7 or ddos_l4)

API Error Codes

Error Code	Message	Cause	Solution
10000	Authentication error	Invalid/missing API token	Check token has DDoS permissions
81000	Ruleset validation failed	Invalid rule structure	Verify `action_parameters.id` is managed ruleset ID
81020	Expression not allowed	Custom expressions on wrong plan	Use `"true"` or upgrade to Enterprise Advanced
81021	Rule limit exceeded	Too many override rules	Reduce rules or upgrade (Enterprise Advanced: 10)
81022	Invalid sensitivity level	Wrong sensitivity value	Use: `default`, `medium`, `low`, `eoff`
81023	Invalid action	Wrong action for plan	Enterprise Advanced only: `log` action

Limits

Log action	✗	✗	✓

Traffic history required	-	7 days	7 days

Tuning Strategy

Start with log action + medium sensitivity
Monitor for 24-48 hours
Identify false positives, add exceptions
Gradually increase to default sensitivity
Change action from log → managed_challenge → block
Document all adjustments

Best Practices

Test during low-traffic periods
Use zone-level for per-site tuning
Reference IP lists for easier management
Set appropriate alert thresholds (avoid noise)
Combine with WAF for layered defense
Avoid over-tuning (keep config simple)
