Introduction
Have you ever wondered what it would be like to have a virtual development team that could understand your ideas and automatically complete the entire process from requirements analysis to code delivery?
This isn't science fiction—it's happening right now.
Think about our daily development work. Aren't there always some repetitive tasks that give us headaches? When a requirement change comes in, you have to update the requirements document, then update the design document, modify the code, and update test cases... And you have to constantly communicate with product managers, designers, and test engineers throughout these stages. Time gets consumed bit by bit on these mechanical tasks, leaving little time for truly valuable creative work.
Over the years, we've witnessed the rapid evolution of development tools. From IDE code completion, to intelligent coding assistants like GitHub Copilot, to today's AI Agents. But most of these tools still remain at the "assistance" level—they can help you write a few lines of code, but cannot understand the entire software development lifecycle.
Cowork Forge attempts to break this limitation. It's not a simple code completion tool, but a complete software development automation platform. By coordinating 7 specialized AI agents, it collaborates like a real development team, transforming your ideas step by step into production-ready code.
In this article, I'll take you deep into how Cowork Forge works, showing you how these AI agents divide and collaborate, and how it differs from existing AI development tools.
Traditional Development vs. AI Collaborative Development
Before diving into Cowork Forge, let's look at the differences between traditional development patterns and AI collaborative development patterns.
The Real Experience of Traditional Development Patterns
The traditional software development process is something we're all familiar with. The product manager holds a requirements meeting, organizes the requirements document, and writes the PRD. The technical lead receives the PRD and starts architectural design, writing technical documentation. Developers receive the design document and start writing code. Testers receive the code and write test cases, executing tests. Operations personnel receive the code that passed tests and deploy it to production.
This process sounds standardized, but in practice, there are many problems.
First, too much manual work. Every stage requires significant human involvement, and much of the work is repetitive. For example, formatting requirements documents, drawing design documents, writing test cases... While this work is important, it's truly time-consuming.
Second, high communication costs. Team members need to communicate frequently, and information can easily get distorted during transmission. A product manager describes a requirement, the technical lead understands it as something else, and what the developer implements might be yet another thing. This "telephone game" is all too common in the development process.
Third, knowledge silos. Requirements, design, and code are scattered across different people and documents, making it difficult to maintain consistency. When requirements change, you have to manually modify multiple stages—not only is it inefficient, but it's also easy to miss things.
Changes Brought by AI Collaborative Development
AI collaborative development patterns thoroughly transform this process through agent automation and collaboration.
In the requirements processing stage, AI can automatically structure your ideas and generate professional requirements documents. In the document generation stage, AI can automatically generate PRDs and design documents based on requirements. In the code generation stage, AI can plan and execute code changes. In the quality verification stage, AI can automate building, testing, and verification. In the change management stage, AI can intelligently identify the scope of impact and update only affected files.
What are the core advantages of this pattern?
First, end-to-end automation. The complete process from idea to delivery can be automated, greatly reducing manual intervention stages. You don't need to switch between multiple tools—all stage outputs are unified in storage and management.
Second, specialized division of labor. Each agent focuses on a specific domain, providing specialized output. For example, the PRD agent focuses on product requirements and outputs professional PRD documents; the design agent focuses on technical architecture and applies design methods like the C4 model; the coding agent focuses on code generation and supports incremental updates; the check agent focuses on quality verification and automates building and testing.
Third, context sharing. All agents share a unified context, ensuring consistency across all stages. When requirements change, AI can quickly identify the scope of impact and update relevant content.
Fourth, rapid response. Compared to traditional patterns, AI collaborative development responds much faster. When requirements change, there's no need to manually modify multiple stages—AI can automatically handle most of the work.
Role Division Among the 7 Agents
The core of Cowork Forge is 7 specialized AI agents, each responsible for different stages of software development. They collaborate like a real development team, each performing their own duties.
Overall Architecture
Cowork Forge adopts a layered architecture design, divided from top to bottom into the agent collaboration layer, orchestration layer, and infrastructure layer.
In this architecture, the orchestration layer is responsible for coordinating agent execution, while the infrastructure layer provides foundational capabilities including tool support, verification security, data management, and interaction control. The benefit of this layered design is clear responsibility separation—the orchestration layer focuses on process control, the agent layer focuses on business logic, and the infrastructure layer provides common capabilities.
Agent Collaboration Process
The 7 agents collaborate according to a predefined process, with each agent passing results to the next agent after completing its own task. This process isn't simple linear execution, but an intelligent process with feedback loops.
An important feature of this process is intelligent rollback. When the check stage discovers a problem, the feedback agent doesn't simply request re-execution. Instead, it intelligently analyzes the root cause of the problem and determines which stage to re-execute from. If the problem is a misunderstanding of requirements, it returns to the PRD stage; if it's a design problem, it returns to the design stage; if it's a code implementation problem, it returns to the coding stage. This intelligent rollback mechanism greatly improves problem-solving efficiency.
Responsibilities of Each Agent
Let's look at what each of these agents does.
Requirements Collection Agent is the first to take the stage. Its task is to transform your ideas—which might be just a sentence like "I want to build a task management app"—into a structured requirements specification. This is like an experienced product manager who can extract real requirements from your simple description. It needs to understand vague requirement descriptions, identify key requirement points, and even ask clarification questions through the HITL mechanism.
PRD Agent, after receiving the structured requirements specification, generates a complete Product Requirements Document. It needs to transform requirements into a professional PRD format, identify dependencies between requirements, and perform priority sorting. This is like a professional product manager who can write clear, complete product documents.
Design Agent generates technical architecture and design solutions based on the PRD. It needs to apply professional architecture models, make technology selection decisions, and apply appropriate architecture patterns. This is like a senior technical lead who can design reasonable technical solutions.
Coding Stage Agent is the most complex agent, responsible for planning and executing code changes and supporting incremental updates. It contains three sub-components internally: CodePlanner is responsible for generating code change plans, CodeExecutor is responsible for executing code generation, and CodeUpdater is responsible for supporting incremental code updates. It needs to analyze project structure, plan code changes, support incremental updates, and safely execute code.
Check Agent is responsible for verifying code quality and project build status. It needs to detect project types (supporting Rust, Python, JavaScript/TypeScript), automate building and testing, analyze errors, and calculate requirements coverage. It generates a check report containing build results, test results, error analysis, quality metrics, etc.
If the check discovers problems, the Feedback Agent takes the stage. It's responsible for analyzing user feedback and determining the scope of re-execution. It analyzes feedback content, identifies the scope of impact, and intelligently decides which stage to re-execute. It generates feedback artifacts containing change requirement analysis, re-execution stage decisions, and modification suggestions.
Finally, there's the Delivery Agent. It's responsible for generating a delivery report that summarizes the entire development process. It aggregates information from all stages to generate a complete delivery report containing an implementation summary, requirements coverage, quality metrics, follow-up recommendations, etc.
Why Do We Need Multiple Agents?
You might ask: Why can't one all-powerful AI complete all the work? There are several reasons.
First, specialized capabilities. Different stages of software development require different professional knowledge and skills. Requirements analysis requires product thinking and user perspective, technical design requires architecture experience and engineering practice, code generation requires programming language and framework knowledge, and test verification requires quality assurance experience. Through specialized division of labor, each agent can provide higher quality output in its domain.
Second, single responsibility. The single responsibility principle applies not only to code design but also to agent design. Each agent focuses on a clear responsibility, making agent behavior more predictable, errors easier to locate and fix, and agents easier to test and verify.
Third, scalability. Multi-agent architecture has good scalability. You can easily add new agents, such as a performance optimization agent, a security audit agent. Each agent can be independently optimized and upgraded, and agents can be dynamically loaded as plugins.
Fourth, parallel processing. The work of certain agents can be performed in parallel, improving overall efficiency. For example, document generation and code planning can be parallelized, and code generation for multiple files can be parallelized.
End-to-End Workflow Experience
Having discussed so much theory, let's look at how Cowork Forge completes the entire development process from idea to code through a real case.
A Real Scenario
Suppose you have an idea: "I want to build a task management REST API that supports creating tasks, updating task status, and querying task lists."
With just this simple sentence, Cowork Forge can start working.
Complete Workflow
This sequence diagram shows the complete end-to-end workflow. You can see that each agent has its own responsibilities, and they transfer data through artifacts. The HITL controller intervenes at key nodes, letting users confirm AI outputs to ensure quality and controllability.
What Actually Happens at Each Stage
Stage 1: Requirements Collection
You input the sentence "I want to build a task management REST API that supports creating tasks, updating task status, and querying task lists."
The Requirements Collection Agent starts working. It calls the LLM to structure your sentence into an IdeaSpec. It identifies that the core goal is "build a task management REST API," the functional scope includes "create tasks," "update task status," "query task lists," the user role is "regular user," and constraints include "use RESTful architecture," "support concurrent access," "data persistence."
Then through the HITL mechanism, it displays this structured requirements specification to you for confirmation. After you confirm, this stage is complete.
Stage 2: PRD Generation
After receiving the IdeaSpec, the PRD Agent starts generating the Product Requirements Document.
It generates a complete PRD containing product overview, functional requirements list, user stories and acceptance criteria, and non-functional requirements. For example, for the "create task" function, it writes the function description, inputs (task title required, task description optional, task status defaults to "pending"), and outputs (task ID and task information).
Similarly, it displays the PRD to you through the HITL mechanism for confirmation.
Stage 3: Technical Design
After receiving the PRD, the Design Agent starts generating technical architecture and design solutions.
It generates a design document containing system architecture design (using C4 model), technology stack selection recommendations, component and module division, data model design, and interface definitions. For example, it selects Rust as the development language, Actix-web as the web framework, SQLite as the database, and Diesel as the ORM. It designs the Task data model, defines the TaskStatus enum, and plans the API interfaces.
Similarly, it displays the design document to you through the HITL mechanism for confirmation.
Stage 4: Coding
After receiving the design document, the Coding Stage Agent starts planning and executing code changes.
It first analyzes the project structure and generates a code change plan. For example, it plans the files that need to be created: src/main.rs, src/models.rs, src/db.rs, src/handlers.rs, src/routes.rs.
Then it generates the actual code. For example, in src/models.rs, it generates the Task struct and NewTask struct, including all necessary fields and serialization markers.
Similarly, it displays the code plan to you through the HITL mechanism for confirmation.
Stage 5: Check
After receiving the code, the Check Agent starts verifying code quality and project build status.
It runs builds and tests, generating a check report. The report shows build status (success or failure), test results (pass or fail), error analysis, and quality metrics (code coverage, cyclomatic complexity, etc.).
Stage 6: Delivery
After receiving artifacts from all stages, the Delivery Agent generates a delivery report.
This report summarizes the entire development process, including implementation summary, requirements coverage, quality metrics, and follow-up recommendations. For example, it tells you that all functional requirements have been implemented, build status passed, test pass rate is 100%, code coverage is 85%, and suggests adding user authentication and authorization, implementing task tags and categorization features in the future.
Human Verification at Key Nodes
You may have noticed that there are several key nodes in the entire workflow that require your human verification.
Requirements collection confirmation, PRD confirmation, design confirmation, code plan confirmation—these nodes all require you to review AI outputs and confirm they're correct before continuing.
This HITL (Human-in-the-Loop) mechanism ensures the quality and controllability of AI-generated content, finding a balance between automation efficiency and human control. You don't completely lose control—instead, you still have a say at key decision points.

This comparison table clearly shows Cowork Forge's differentiated advantages. Unlike code completion tools that only assist with writing single lines of code, Cowork Forge manages the entire software development process—from initial idea collection to final delivery. This comprehensive approach ensures consistency and traceability across all stages.
Core Differentiation Advantages
Complete Development Lifecycle is the first differentiation advantage of Cowork Forge. Unlike code completion tools that only assist with writing single lines of code, Cowork Forge manages the entire software development process—from initial idea collection to final delivery. This comprehensive approach ensures consistency and traceability across all stages. You don't need to switch between multiple tools—all stage outputs are unified in storage and management. When requirements change, you can trace the impact to all related stages.
Multi-Agent Collaboration is the second differentiation advantage. Cowork Forge's 7 specialized agents collaborate like a real development team, with each agent bringing professional expertise in its domain. The PRD agent focuses on product requirements and outputs professional PRD documents; the design agent focuses on technical architecture and applies design methods like the C4 model; the coding agent focuses on code generation and supports incremental updates; the check agent focuses on quality verification and automates building and testing. This specialized division of labor ensures output quality at each stage.
Human-AI Collaboration Verification is the third differentiation advantage. Key outputs require human confirmation before proceeding, ensuring accurate requirement capture, reasonable technical decisions, and safe code changes. This balance between automation and human control distinguishes Cowork Forge from fully autonomous tools. You can control AI outputs, avoid erroneous decisions, intervene and adjust at key nodes, and retain control over the development process.
Incremental Code Updates is the fourth differentiation advantage. When requirements or designs change, Cowork Forge intelligently identifies affected files and only updates necessary content—preserving your customizations and avoiding full regeneration. This means it won't overwrite code you've manually modified, changes are more precise, unnecessary modifications are reduced, and development efficiency is improved, especially in iterative development.
Built-in Security is the fifth differentiation advantage. Multi-layer security checks prevent dangerous command execution (rm -rf, sudo, etc.), unauthorized file system access, malicious code injection, and resource exhaustion. This means you can confidently let AI execute code operations without worrying about AI deleting important files or executing dangerous commands, providing enterprise-level security guarantees.
Applicable Scenario Analysis
Cowork Forge is best suited for scenarios including: rapid new project startup (from idea to prototype, quickly validating product concepts, automatically generating project foundation and core features), incremental feature development (adding new features to existing projects, rapid response to requirement changes), small to medium projects (small team size, need to improve development efficiency, moderate project complexity suitable for automation), and documentation-driven development (need complete PRDs, design documents, emphasizing consistency between requirements and design).
Less suitable scenarios include: highly customized complex systems (complex business logic requiring many human decisions, special technology stacks where AI lacks relevant knowledge), creative design (UI/UX design requiring human creativity and aesthetics, product innovation requiring human insight), and systems with extreme performance requirements (performance-critical code requiring deep optimization, fine-grained resource management).
Summary and Outlook
Cowork Forge represents a new paradigm for AI-driven software development automation. Through multi-agent collaboration, it achieves end-to-end automation from idea to code, while retaining human control over key decisions.
Core Value Review
Cowork Forge's core value lies in: end-to-end automation (complete process automation from requirements collection to code delivery), specialized division of labor (7 agents each performing their duties, providing specialized output), human-AI collaboration (human verification at key decision points ensuring quality and controllability), incremental updates (intelligent scope identification avoiding full regeneration), and security-first (multi-layer security checks ensuring safe code execution).
Future Evolution Directions
Cowork Forge continues to evolve, with future development directions including: distributed architecture (supporting multi-machine collaboration for complex projects, improving concurrent processing capabilities), agent learning capabilities (optimizing agent behavior based on historical sessions, personalized recommendations and optimization), multi-modal support (supporting more input forms like images, audio, supporting more output types like UI prototypes), team collaboration features (multiple users participating in the same project simultaneously, real-time collaboration and conflict resolution), and more agents (performance optimization agent, security audit agent, documentation generation agent).
Recommendations for Developers
If you're considering using Cowork Forge, here are some recommendations: start with small projects (try it on simple projects first, get familiar with the workflow, gradually apply to more complex projects), make full use of HITL (don't skip human verification steps, carefully review AI outputs at key nodes), understand agent capability boundaries (know what each agent can and cannot do, use the right tool for the right scenario), maintain code quality (don't fully rely on AI, still perform code reviews, maintain good coding habits and standards), and provide feedback (if AI output doesn't meet expectations, provide detailed feedback to help improve agent behavior).
Conclusion
AI is changing the way software is developed, and Cowork Forge is an important attempt in this transformation. It's not meant to replace developers, but to become a capable assistant helping us complete repetitive work more efficiently, allowing us to focus on more valuable creative work.
Just as IDEs won't replace developers, GitHub Copilot won't replace developers, AI Agents won't replace developers either. They're just tools that help us improve efficiency, enabling us to do more.
The future belongs to developers who can skillfully use AI tools. Let's embrace this new era together.
