## What it does

Wrangler is the CLI for Cloudflare Workers, and its flags, config fields and subcommands move faster than model training data. This skill fixes that: before touching a wrangler task, the agent pulls current information from the Cloudflare docs and from `node_modules/wrangler/config-schema.json` instead of trusting what it already knows.

Inside is a retrieval table (wrangler docs, config schema, API reference), a version check with `wrangler --version` that expects v4.x+, and `npm install -D wrangler@latest` if the CLI is missing. Then the working rules: `wrangler.jsonc` over TOML, a recent `compatibility_date`, `wrangler types` after config edits, `wrangler check` before deploy, separate staging and production environments. There is a command reference too — `wrangler dev`, `wrangler deploy`, `wrangler tail`, plus KV, secrets, versions and rollbacks.

One detail matters more than the rest. Local dev uses simulated storage by default, so bindings do not touch real resources until you set `remote: true` in the binding config. Workers AI always needs it. Skip that and the agent writes code that passes locally and behaves differently against live data.

## Install

### Codex (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill wrangler -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/wrangler/SKILL.md` — For all projects use ~/.agents/skills/

### Claude Code

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill wrangler -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/wrangler/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/wrangler/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/wrangler/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install openai/plugins wrangler
```

2. **Manually: put the files in place**
- File: `.github/skills/wrangler/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/openai/plugins --path plugins/cloudflare/skills/wrangler
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/wrangler/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/openai/plugins/tree/HEAD/plugins/cloudflare/skills/wrangler/SKILL.md

## When to use it
- check wrangler command syntax before running it
- build a `wrangler.jsonc` with KV, R2 and D1 bindings
- point local dev at real Cloudflare resources
- regenerate TypeScript types after config changes
- roll a Worker back to a previous version

## Example prompts
- Add an R2 binding to `wrangler.jsonc` and generate types
- Deploy the Worker to the staging environment
- Set up a cron trigger and test it locally

# 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: Verify Wrangler Installation

```bash
wrangler --version  # Requires v4.x+
```

If not installed:
```bash
npm install -D wrangler@latest
```

## 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`.
- **Validate config before deploy**: Run `wrangler check` to catch errors early.
- **Use environments for staging/prod**: Define `env.staging` and `env.production` in config.

## Quick Start: New Worker

```bash
# Initialize new project
npx wrangler init my-worker

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

## Quick Reference: Core Commands

| Task | Command |
|------|---------|
| Start local dev server | `wrangler dev` |
| Deploy to Cloudflare | `wrangler deploy` |
| Deploy dry run | `wrangler deploy --dry-run` |
| Generate TypeScript types | `wrangler types` |
| Validate configuration | `wrangler check` |
| View live logs | `wrangler tail` |
| Delete Worker | `wrangler delete` |
| Auth status | `wrangler whoami` |

## Configuration (wrangler.jsonc)

### Minimal Config

```jsonc
{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "name": "my-worker",
  "main": "src/index.ts",
  "compatibility_date": "2026-03-18"
}
```

### Full Config with Bindings

```jsonc
{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "name": "my-worker",
  "main": "src/index.ts",
  "compatibility_date": "2026-03-18",
  "compatibility_flags": ["nodejs_compat_v2"],

  // Environment variables
  "vars": {
    "ENVIRONMENT": "production"
  },

  // KV Namespace
  "kv_namespaces": [
