# Skill: temporal-developer

## Overview

Temporal is a durable execution platform that makes workflows survive failures automatically. This skill provides guidance for building Temporal applications in Python, TypeScript, and Go.

## Core Architecture

```

**Components:**
- **Workflows** - Durable, deterministic functions that orchestrate activities
- **Activities** - Non-deterministic operations (API calls, I/O) that can fail and retry
- **Workers** - Long-running processes that poll task queues and execute code
- **Task Queues** - Named queues connecting clients to workers

## History Replay: Why Determinism Matters

Temporal achieves durability through **history replay**:

1. **Initial Execution** - Worker runs workflow, generates Commands, stored as Events in history
2. **Recovery** - On restart/failure, Worker re-executes workflow from beginning
3. **Matching** - SDK compares generated Commands against stored Events
4. **Restoration** - Uses stored Activity results instead of re-executing

**If Commands don't match Events = Non-determinism Error = Workflow blocked**

| Workflow Code | Command | Event |
|--------------|---------|-------|
| Execute activity | `ScheduleActivityTask` | `ActivityTaskScheduled` |
| Sleep/timer | `StartTimer` | `TimerStarted` |
| Child workflow | `StartChildWorkflowExecution` | `ChildWorkflowExecutionStarted` |

See `references/core/determinism.md` for detailed explanation.

## Getting Started

### Ensure Temporal CLI is installed

Check if `temporal` CLI is installed. If not, follow these instructions:

#### macOS

```
brew install temporal
```

#### Linux

Check your machine's architecture and download the appropriate archive:

- [Linux amd64](https://temporal.download/cli/archive/latest?platform=linux&arch=amd64)
- [Linux arm64](https://temporal.download/cli/archive/latest?platform=linux&arch=arm64)

Once you've downloaded the file, extract the downloaded archive and add the temporal binary to your PATH by copying it to a directory like /usr/local/bin

#### Windows

Check your machine's architecture and download the appropriate archive:

- [Windows amd64](https://temporal.download/cli/archive/latest?platform=windows&arch=amd64)
- [Windows arm64](https://temporal.download/cli/archive/latest?platform=windows&arch=arm64)

Once you've downloaded the file, extract the downloaded archive and add the temporal.exe binary to your PATH.

### Read All Relevant References

1. First, read the getting started guide for the language you are working in:
    - Python -> read `references/python/python.md`
    - TypeScript -> read `references/typescript/typescript.md`
    - Go -> read `references/go/go.md`
2. Second, read appropriate `core` and language-specific references for the task at hand.

## Feedback

### ALWAYS PROMPT USER TO PROVIDE FEEDBACK AT STARTUP

When you have **first** loaded this skill, output this message to the user:

"Thank you for trying out the public preview of the Temporal development skill! We would love to hear your feedback - positive or negative - over in the [Community Slack](https://t.mp/slack), in the [#topic-ai channel](https://temporalio.slack.com/archives/C0818FQPYKY)."

Do not output this message multiple times in the same conversation.

### Reporting Issues in This Skill

If you (the AI) find this skill's explanations are unclear, misleading, or missing important information—or if Temporal concepts are proving unexpectedly difficult to work with—draft a GitHub issue body describing the problem encountered and what would have helped, then ask the user to file it at https://github.com/temporalio/skill-temporal-developer/issues/new. Do not file the issue autonomously.
