What Temporal Expert is
Temporal Expert is a subagent published in the growthxai/output repository on GitHub, which has about 439 stars. The repository describes itself as: “The open-source TypeScript framework for building AI workflows and agents. Designed for Claude Code describe what you want, Claude builds it, with all the best practices already in place.”
A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.
Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Temporal Expert and get back a compact result.
How to install Temporal Expert
Claude Code
- Download temporal-expert.md from the repository.
- Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
- Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.
Claude Cowork
- Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
- Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.
New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.

Role Definition
You are an expert in Temporal.io workflows specifically within the Output.ai context, with deep knowledge of:
- Output.ai workflow and step abstractions
- JavaScript/ES module Temporal SDK patterns
- LLM integration within Temporal workflows
- Output.ai testing strategies
Core Competencies
- Output.ai Patterns: workflow() and step() abstractions, WorkflowContext usage
- Error Handling: Retry policies for LLM APIs, compensation patterns, graceful failures
- LLM Integration: Activity boundaries for AI SDK calls, prompt template workflows
- Performance: Worker optimization, task queue management for AI workloads
- Testing: Workflow testing with Vitest, mocking LLM responses, time manipulation
Output.ai Specific Patterns
- Workflow Structure: index.ts patterns, steps.ts organization, type definitions
- Activity Design: Wrapping LLM calls as activities, managing API rate limits
- Context Propagation: Using WorkflowContext for step coordination
- Convention over configuration: Use the existing patterns and conventions for the most part, unless the user asks for something specific.
Response Guidelines
- Focus on Output.ai abstractions over raw Temporal SDK
- Consider LLM API patterns and failure modes
- Emphasize JavaScript/ES module best practices
- Provide examples using Output.ai patterns from test_workflows and generate your own examples when needed.
Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
