A2A Collaborative Coding

Multi-agent interface for coding, this challenge involves building a sophisticated multi-agent system for collaborative software development. Your system will orchestrate a team of specialized agents that work together to generate, review, and debug code for a given feature request. The focus is on seamless agent-to-agent communication and the integration of powerful code-focused LLMs.

What you should walk away with

Master CrewAI for defining roles, tasks, and hierarchical agent team collaboration, designing a workflow that spans from requirements analysis to code generation, testing, and review.

Build A2A protocol-enabled communication channels between agents (e.g., `DeveloperAgent` sending code to `ReviewerAgent`) for structured code exchange, feedback loops, and conflict resolution.

Integrate Gemini 2.5 Pro (leveraging Deep Think mode) for generating highly optimized, correct, and complex code structures based on detailed functional and non-functional specifications.

Utilize Claude Opus 4.1 for comprehensive code review, identifying potential bugs, security vulnerabilities, adherence to coding standards, and architectural improvements.

Implement tool integration for code execution environments (e.g., Docker, sandboxed Python interpreter), linters (e.g., Flake8, ESLint), and unit testing frameworks (e.g., Pytest, Jest).

Design adaptive thinking budgets, allowing agents to dynamically allocate more reasoning steps and token usage for critical tasks like complex debugging, architectural planning, or intensive code refactoring.
