description: Run or troubleshoot Wrangler CLI commands in projects that have a wrangler.jsonc, wrangler.json, or wrangler.toml file, including local development, Previews, deployment, and resource management. For new projects and projects without a Wrangler configuration file, use the cf CLI instead.

# Wrangler CLI

Use this skill only when the project has `wrangler.jsonc`, `wrangler.json`, or `wrangler.toml` and no `cloudflare.config.ts`, or when the user asks for Wrangler. For a new project, a project with `cloudflare.config.ts`, or a project with no Cloudflare configuration, use the Cloudflare CLI (`cf`) instead: load the `cf-cli` skill if it is installed, or follow [Use cf with coding agents](https://developers.cloudflare.com/cf/agents/index.md). Do not add Wrangler to those projects.

Use the project's Wrangler version and retrieve the relevant documentation before writing commands or configuration. CLI flags and configuration fields change; do not rely on memorized examples.

## Inspect the Project

- Find the package manager, installed Wrangler version, package scripts, framework, and Wrangler config. Run commands through the project's scripts or package manager so they use its local version. Install dependencies using the existing lockfile when needed; do not silently upgrade Wrangler to match current docs. If the project has a Wrangler configuration file but Wrangler is not a dependency, follow the [installation guide](https://developers.cloudflare.com/workers/wrangler/install-and-update/index.md) to add it locally.
- Identify the config used by the build or deploy command, including framework-generated config. Edit its source rather than generated output.
- Establish the target account, Worker, environment, and resource before running commands that change them. For data operations, determine whether the target is local or remote.

## Retrieve What the Task Needs

Use the Cloudflare MCP `docs` tool if available, or fetch the relevant linked page directly. Follow links to the specific command or product involved; avoid loading the entire reference. If a page moves, rediscover it through the [Wrangler command index](https://developers.cloudflare.com/workers/wrangler/commands/index.md) or Cloudflare docs search.

| Decide whether Preview resources are isolated or shared | [Resources and isolation](https://developers.cloudflare.com/workers/previews/resources/index.md), including its current limitations |
| Configure Preview URLs, access, debugging, or CI | [Custom domains](https://developers.cloudflare.com/workers/previews/custom-domains/index.md); [test and debug](https://developers.cloudflare.com/workers/previews/test-and-debug/index.md); [examples](https://developers.cloudflare.com/workers/previews/examples/index.md) |
| Choose between Previews, Version URLs, and Wrangler environments | [Compare workflows](https://developers.cloudflare.com/workers/previews/compare-workflows/index.md) |
| Diagnose authentication or select an account | [General commands](https://developers.cloudflare.com/workers/wrangler/commands/general/index.md), including `whoami`; [authentication profiles](https://developers.cloudflare.com/workers/wrangler/profiles/index.md) |
| Deploy an unauthenticated prototype | [Claim deployments](https://developers.cloudflare.com/workers/platform/claim-deployments/index.md) for eligibility, expiry, and claim URL handling; use a permanent account for production or CI |

Use installed help and schema to check whether documented features exist in the project's version. If a required feature needs an upgrade, make that dependency explicit. If retrieval is unavailable, state the gap and use available local evidence rather than inventing syntax.

## Apply the Change

- Prefer `wrangler.jsonc` for new config. S
