🔧 Technical Requirements

To ensure our designs are technically sound and aligned with best practices, we need to adhere to certain technical requirements. These requirements cover compliance standards and integration points, ensuring that CC-Deck v2 is built on a solid foundation.

Compliance Standards

First and foremost, we need to adhere to Anthropic Claude Code specifications. This means following the guidelines and best practices outlined by Anthropic for Claude Code, ensuring that our system is compatible and well-integrated. You can find more information at https://www.anthropic.com/claude-code. We also need to adhere to sub-agent guidelines. Sub-agents are a key part of the Claude Code ecosystem, and we need to ensure that our use of them aligns with the recommended practices. More details can be found at https://docs.anthropic.com/en/docs/claude-code/sub-agents. In addition, we need to implement proper YAML frontmatter formats. YAML frontmatter is a standardized way to include metadata in our files, and we need to ensure that we’re using it correctly. Finally, we'll ensure kebab-case naming conventions. Kebab-case (e.g., my-file-name) is a common naming convention for files and variables, and we’ll use it consistently to maintain a clean and readable codebase. These compliance standards ensure that our system is built in a consistent and maintainable manner, aligning with industry best practices.

Integration Points

To ensure that CC-Deck v2 works seamlessly within our existing ecosystem, we need to consider our integration points carefully. First, we need to reference existing CLAUDE.md specifications.

We also need to align with the current project structure, making sure that our new components and workflows fit seamlessly into the existing project organization. In addition, we need to document MCP integration strategies. MCP (presumably, Meta-Collaboration Platform) is a key part of our ecosystem, and we need to ensure that CC-Deck v2 integrates smoothly with it. Finally, we should include Kiro.dev and gotalab/claude-code-spec learnings. These are valuable resources that can provide insights and best practices for building systems with Claude Code, and we should leverage them to improve our designs. By carefully considering our integration points, we can ensure that CC-Deck v2 is a valuable addition to our ecosystem, working harmoniously with our existing tools and processes.

📐 Design Principles

To guide our design process and ensure we build a system that meets our needs, we need to establish some core design principles. These principles will act as our compass, steering us toward a robust, scalable, and user-friendly CC-Deck v2.

Core Philosophy

Our core philosophy is built on five key principles that will shape every aspect of our design. First, we embrace Simplicity First: Reduce complexity while preserving power. This means that we should always strive for the simplest solution that meets our needs, avoiding unnecessary complexity. Simple systems are easier to understand, maintain, and extend. Second, we champion AI-Native Development: Leverage Claude Code's capabilities. We should fully leverage the capabilities of Claude Code, designing our system to take advantage of its strengths and capabilities. Third, we commit to Quality Without Compromise: Maintain TDD practices. Test-Driven Development (TDD) is a cornerstone of our development process, and we should maintain it without compromise, ensuring that our system is robust and reliable. Fourth, we value Human-Centric Approval: All critical decisions require human oversight. While automation is powerful, human oversight is essential for critical decisions, ensuring that we maintain control and accountability. Fifth, we adhere to Specification-Driven: Clear requirements drive implementation. Clear and well-defined specifications are the foundation of any successful project, and we should always let our requirements drive our implementation. These core principles ensure that we build a system that is simple, powerful, AI-native, high-quality, and human-centric.

Architecture Patterns

In addition to our core philosophy, we'll also employ specific architecture patterns to guide our design. First, we'll use Agent Specialization: Domain-specific sub-agents. This means that we'll break our system into specialized agents, each responsible for a specific domain or task. This promotes modularity and allows us to leverage the strengths of different AI models. Second, we'll implement Context-Aware Orchestration: Dynamic agent selection. Our system should be able to dynamically select the appropriate agent based on the current context, ensuring that we're always using the right tool for the job. Third, we'll design an Extensible Architecture: Modular design supporting plugins. Our system should be modular and support plugins, allowing us to easily extend its functionality without modifying the core codebase. These architecture patterns ensure that our system is modular, flexible, and extensible, allowing us to adapt to changing requirements and leverage the latest advancements in AI.
