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

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.

Bot Management Gotchas

Common Errors

"Bot Score = 0"

Cause: Bot Management didn't run (internal Cloudflare request, Worker routing to zone (Orange-to-Orange), or request handled before BM (Redirect Rules, etc.)) Solution: Check request flow and ensure Bot Management runs in request lifecycle

"JavaScript Detections Not Working"

Cause: js_detection.passed always false or undefined due to: CSP headers don't allow /cdn-cgi/challenge-platform/, using on first page visit (needs HTML page first), ad blockers or disabled JS, JSD not enabled in dashboard, or using Block action (must use Managed Challenge) Solution: Add CSP header Content-Security-Policy: script-src 'self' /cdn-cgi/challenge-platform/; and ensure JSD is enabled with Managed Challenge action

"False Positives (Legitimate Users Blocked)"

Cause: Bot detection incorrectly flagging legitimate users Solution: Check Bot Analytics for affected IPs/paths, identify detection source (ML, Heuristics, etc.), create exception rule like (cf.bot_management.score lt 30 and http.request.uri.path eq "/problematic-path") with Action: Skip (Bot Management), or allowlist by IP/ASN/country

"False Negatives (Bots Not Caught)"

Cause: Bots bypassing detection Solution: Lower score threshold (30 → 50), enable JavaScript Detections, add JA3/JA4 fingerprinting rules, or use rate limiting as fallback

"Verified Bot Blocked"

Cause: Search engine bot blocked by WAF Managed Rules (not just Bot Management) Solution: Create WAF exception for specific rule ID and verify bot via reverse DNS

"Yandex Bot Blocked During IP Update"

Cause: Yandex updates bot IPs; new IPs unrecognized for 48h during propagation Solution:

Check Security Events for specific WAF rule ID blocking Yandex

Create WAF exception:

(http.user_agent contains "YandexBot" and ip.src in {<yandex-ip-range>})
Action: Skip (WAF Managed Ruleset)

Monitor Bot Analytics for 48h
Remove exception after propagation completes

Issue resolves automatically after 48h. Contact Cloudflare Support if persists.

"JA3/JA4 Missing"

Cause: Non-HTTPS traffic, Worker routing traffic, Orange-to-Orange traffic via Worker, or Bot Management skipped Solution: JA3/JA4 only available for HTTPS/TLS traffic; check request routing

JA3/JA4 Not User-Unique: Same browser/library version = same fingerprint

Don't use for user identification
Use for client profiling only
Fingerprints change with browser updates

Bot Verification Methods

Cloudflare verifies bots via:

Reverse DNS (IP validation): Traditional method—bot IP resolves to expected domain
Web Bot Auth: Modern cryptographic verification—faster propagation

When verifiedBot=true, bot passed at least one method.

Inactive verified bots: IPs removed after 24h of no traffic.

Detection Engine Behavior

Engine	Score	Timing	Plan	Notes
Heuristics	Always 1	Immediate	All	Known fingerprints—overrides ML
ML	1-99	Immediate	All	Majority of detections
Anomaly Detection	Influences	After baseline	Enterprise	Optional, baseline analysis
JavaScript Detections	Pass/fail	After JS	Pro+	Headless browser detection
Cloudflare Service	N/A	N/A	Enterprise	Zero Trust internal source

Priority: Heuristics > ML—if heuristic matches, score=1 regardless of ML.
