Cloudflare Platform Skill

Consolidated skill for building on the Cloudflare platform. Use decision trees below to find the right product, then load detailed references.

How to Use This Skill

Reference File Structure

Each product in ./references/<product>/ contains a README.md as the entry point, which may be structured in one of two ways:

Multi-file format (5 files): | File | Purpose | When to Read | |------|---------|--------------| | README.md | Overview, when to use, getting started | Always read first | | api.md | Runtime API, types, method signatures | Writing code | | configuration.md | wrangler.toml, bindings, setup | Configuring a project | | patterns.md | Common patterns, best practices | Implementation guidance | | gotchas.md | Pitfalls, limitations, edge cases | Debugging, avoiding mistakes |

Single-file format: All information consolidated in README.md.

Reading Order

1. Start with README.md
2. Then read additional files relevant to your task (if multi-file format): - Building feature → api.md + patterns.md - Setting up project → configuration.md - Troubleshooting → gotchas.md

Example Paths

./references/workflows/README.md         # Start here for Workflows
./references/workflows/api.md            # Workflow class, step methods
./references/durable-objects/gotchas.md  # DO limitations
./references/workers-ai/README.md        # Single-file - all Workers AI docs

Quick Decision Trees

"I need to run code"

Need to run code?
├─ Serverless functions at the edge → workers/
