# temporal-cloud-setup

A Codex skill that walks the agent through Temporal Cloud setup and runs a sample Workflow. Useful when you need a cloud namespace from scratch.

## What it does

The skill drives the agent through phases: preflight, CLI install, browser sign-in, namespace and API key creation, cloning the money-transfer sample, writing `temporal.toml`, then starting the Worker and the Workflow. The agent does the work itself and asks only about SDK and region.

Under the hood sits `scripts/provision.sh` with subcommands. Before each run the agent renders a gate showing the command, and approval comes from your tool-permission prompt. Three steps wait for a separate go-ahead: `login`, `run-workflow` and inject-failure.

You need a local shell with outbound network, because the skill talks to the Temporal Cloud API over gRPC at `*.tmprl.cloud`. A sandbox that blocks egress will not work — and `login` plus `whoami` still pass there, since both run offline, so a green `whoami` only proves a credential exists. Run `regions` to check real connectivity.

## Install

### Codex (native platform)

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

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

### Claude Code

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

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

### Cursor

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install openai/plugins temporal-cloud-setup
```

2. **Manually: put the files in place**

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/openai/plugins --path plugins/temporal/skills/temporal-cloud-setup
```

### Windsurf (Devin Desktop)

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

### Claude.ai

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

## When to use it
- stand up Temporal Cloud without losing track of the steps
- create a namespace and API key for the cloud environment
- write the client `temporal.toml` config
- connect a local Worker to the cloud and run a sample Workflow
- diagnose why Cloud sign-in fails inside a sandbox

## Example prompts
- Set up Temporal Cloud and run a sample Workflow
- Create the namespace and API key, then write the client config
- Connect my local Worker to Temporal Cloud and run the money-transfer sample

name: temporal-cloud-setup
description: Set up Temporal Cloud and run a sample Workflow on it for the user, doing the work end to end. Use when the user wants to set up Temporal Cloud, get started on Temporal Cloud, install the unified Temporal CLI (prerelease cloud-cli), create a Cloud namespace or API key, clone a money-transfer sample app, write the client config TOML, or connect a local Worker to Temporal Cloud and run a sample Workflow. This is the Cloud setup path, not the local learning path (see temporal-getting-started). Covers Python, TypeScript, Go, Java, .NET, and Ruby SDKs.

# Temporal Cloud Setup

## Role

You are an operator running the Temporal Cloud setup **for** the user. Do the work; do not turn this into a lecture. Ask a question only when you genuinely cannot proceed without the user's input (SDK choice, picking a region, browser login). Everything else — installing, cloning, creating the namespace + key, writing the TOML, starting the Worker, starting the Workflow — you perform yourself.

This is the **Cloud** path. It is distinct from `temporal-getting-started`, which teaches Temporal locally with `temporal server start-dev`. If the user wants to learn concepts locally, hand off to that skill instead.

**Environment this skill needs — a local shell with outbound network.** It shells out to the real CLI and reaches the Temporal Cloud API over gRPC (`*.tmprl.cloud`). It will **not** work from a sandbox that blocks outbound network. The trap: browser sign-in (`login`) and `whoami` both succeed **offline** — `login` uses a `127.0.0.1` loopback and `whoami` reads a cached token with no live API call — so a passing `whoami` proves only that a **credential is present**, never that the Cloud API is reachable. `regions` runs an authoritative post-login connectivity pulse; if it reports `cloud-unreachable`, the fix is **network / sandbox connectivity, not re-authentication** (see Failure Handling). Run this skill somewhere with real network egress (Codex's default sandbox does not qualify).

## Output contract — how you drive every step

For many users this is the **first time they ever see Temporal.** It's a guided, phased wizard for a newcomer: the work is real, the wizard is the presentation. **The tracker + step checklists tell the story — not prose.**

<output-contract>

**The per-step loop — disclose every command, then run it. The user's own tool-permission prompt is the approval (it shows them the same command and they allow/deny it there); the skill does not add its own approval — except three deliberate steps that wait for a go-ahead.**
