Agent Workflow: Orchestrator-Subagent Workflow Skill Set for Claude Code and Codex

Agent Workflow is a workflow skill set specifically designed for AI programming agents (Claude Code and Codex), implementing the Orchestrator-Subagent architectural pattern. This pattern decomposes complex tasks into multiple subtasks, which are processed in parallel by specialized subagents, then the orchestrator coordinates and integrates the results, significantly enhancing the ability of AI programming assistants to handle complex projects.

With the popularity of AI programming assistants like Claude Code and Codex, developers are increasingly relying on these tools to complete more complex development tasks. However, when facing large-scale projects or complex requirements, the single-agent model reveals obvious limitations:

Even the most advanced models have context length limitations. When dealing with a large codebase containing thousands of files, it is impractical to fit all code into the context. This causes the agent to only see parts of the project, making it difficult to make globally optimal decisions.

Complex tasks often involve multiple sub-fields:

• Frontend interface design and implementation
• Backend API development
• Database schema design
• Test case writing
• Deployment configuration

Having a single agent handle all these aspects simultaneously is both inefficient and error-prone.

Different subtasks require different professional knowledge:

• UI/UX design requires aesthetic and interaction design capabilities
• Database optimization requires knowledge of indexing and query optimization
• Security auditing requires understanding common vulnerability patterns

General-purpose agents struggle to reach expert levels in all fields.

In the traditional sequential execution model, an agent can only handle one subtask at a time. However, many subtasks can actually be executed in parallel, so sequential processing wastes a lot of time.

The Agent Workflow project uses the classic Orchestrator-Subagent pattern to solve the above problems. This architectural pattern draws on the design ideas of distributed systems and microservice architectures, applying them to the workflow management of AI agents.
