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Your knowledge of Cloudflare APIs, types, limits, and pricing may be outdated.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.
| Source | How to retrieve | Use for |
|--------|----------------|---------|
| Cloudflare docs | cloudflare-docs search tool or https://developers.cloudflare.com/ | 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.
