Same model, same task: get someone a preview URL with no credentials. Without the card the agent says it’s blocked. With it, wrangler deploy --temporary.
The task
You are helping with a coding task. We have a working Cloudflare Worker project and Wrangler 4.122.0. We need a public preview URL for someone to try. This environment is logged out of Wrangler, has no Cloudflare credentials, and the user does not have a Cloudflare account. Propose the next action we can take from the CLI, or say what blocks us. Include material constraints and what output we should return. Do not execute anything. Do not invent commands or cite sources you were not given.
Without the card
Blocked
“A public Cloudflare-hosted preview requires Wrangler authentication and access to a Cloudflare account.”
Full recorded answer
blocked
A public Cloudflare-hosted preview requires Wrangler authentication and access to a Cloudflare account.
This environment is logged out and has no credentials; the user has no Cloudflare account.
Local Wrangler development can provide only a local URL, not a publicly reachable preview URL.
No project-specific preview command was provided, so an exact CLI command cannot be stated without inventing one.
With the card
Proposes a command
“Run a temporary deployment from the project directory.”
wrangler deploy --temporary
Full recorded answer
Run a temporary deployment from the project directory.
wrangler deploy --temporary
Do not execute this here; the user must run it.
Wrangler 4.122.0 satisfies the stated minimum of 4.102.0.
The deployment requires Wrangler to be logged out with no Cloudflare credentials configured.
The preview remains live for 60 minutes.
Only the products supported by temporary preview accounts can be used; the supplied reference includes Workers and several related products.
