wrangler

wrangler is a skill for Claude Code from YuDefine/nuxt-supabase-starter. It costs 75 tokens per session (4,668 once invoked), scanned A, a copy of wrangler, MIT.

A skill for using Cloudflare's Wrangler command-line tool to develop, deploy, and manage Workers and related services. Workers are programs that run on Cloudflare's network, while services such as KV, R2, and D1 provide storage or databases.

In plain words
What is it for?
Use it for Workers development and deployment, configuration, and management of Cloudflare storage, databases, AI, queues, workflows, containers, and secrets.
Why use it?
Wrangler commands and configuration can change, so the skill requires checking current Cloudflare documentation and installed schemas before acting. This reduces errors from outdated command or configuration details.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is wrangler types ./src/env.d.ts.

Good fit Use it for Workers development and deployment, configuration, and management of Cloudflare storage, databases, AI, queues, workflows, containers, and secrets.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.

Security

Grade A, and why

wrangler scanned grade A with 1 finding 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 10d 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.

Wrangler CLI

Your knowledge of Wrangler CLI flags, config fields, and subcommands may be outdated. Prefer retrieval over pre-training for any Wrangler task.

Retrieval Sources

Fetch the latest information before writing or reviewing Wrangler commands and config. Do not rely on baked-in knowledge for CLI flags, config fields, or binding shapes.

Source How to retrieve Use for
Wrangler docs https://developers.cloudflare.com/workers/wrangler/ CLI commands, flags, config reference
Wrangler config schema node_modules/wrangler/config-schema.json Config fields, binding shapes, allowed values
Cloudflare docs Search tool or https://developers.cloudflare.com/workers/ API reference, compatibility dates/flags

FIRST: Check if Wrangler is installed, and if not, install it

Check if Wrangler is installed by running:

wrangler --version  # Requires v4.x+

If Wrangler is not installed, you should install it by running:

npm install -D wrangler@latest

Wherever possible, you should use Wrangler instead of manually constructing API requests.

Key Guidelines

  • Use wrangler.jsonc: Prefer JSON config over TOML. Newer features are JSON-only.
  • Set compatibility_date: Use a recent date (within 30 days). Check https://developers.cloudflare.com/workers/configuration/compatibility-dates/
  • Generate types after config changes: Run wrangler types to update TypeScript bindings.
  • Local dev defaults to local storage: Bindings use local simulation unless remote: true.
  • Profile Worker startup: Run wrangler check startup to measure startup time and detect scripts that exceed the startup time limit.
  • Use environments for staging/prod: Define env.staging and env.production in config.

Quick Start: New Worker

# Initialize new project
npx wrangler init my-worker

# Or with a framework
npx create-cloudflare@latest my-app

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.
