What is cloudflare-expert?

A development guide for Cloudflare products, including Workers, Pages, storage services, AI tools, networking, security features, and infrastructure-as-code tools. Cloudflare is a platform for running web applications and services at locations close to users.

Use it to build or configure Cloudflare Workers and Pages, use KV, D1, or R2 storage, connect AI services, set up tunnels or network protection, and manage deployments with Terraform or Pulumi.

It helps choose the right Cloudflare product and find the relevant setup, API, usage-pattern, and troubleshooting guidance.

cloudflare-expert — Skill for Claude Code and Codex by hainamchung

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add hainamchung/agent-assistant --skill cloudflare-expert

Clone the repo

git clone --depth 1 https://github.com/hainamchung/agent-assistant

Made for: Claude Code, Codex.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00074	$0.02032
Opus 5	$0.00037	$0.01016
Sonnet 5	$0.00015	$0.00406
Haiku 4.5	$0.00007	$0.00203

Security

Grade A, and why

cloudflare-expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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

Start with README.md
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/
├─ Full-stack web app with Git deploys → pages/
├─ Stateful coordination/real-time → durable-objects/
├─ Long-running multi-step jobs → workflows/
├─ Run containers → containers/
├─ Multi-tenant (customers deploy code) → workers-for-platforms/
└─ Scheduled tasks (cron) → cron-triggers/

"I need to store data"

Need storage?
├─ Key-value (config, sessions, cache) → kv/
├─ Relational SQL → d1/ (SQLite) or hyperdrive/ (existing Postgres/MySQL)
├─ Object/file storage (S3-compatible) → r2/
├─ Message queue (async processing) → queues/
├─ Vector embeddings (AI/semantic search) → vectorize/
├─ Strongly-consistent per-entity state → durable-objects/ (DO storage)
├─ Secrets management → secrets-store/
└─ Streaming ETL to R2 → pipelines/

Files

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cloudflare-expert is a skill published in the GitHub repository hainamchung/agent-assistant (54 stars, last pushed 3mo ago), licensed MIT. It adds 74 tokens to every session and 2,032 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
