Cont3xt.dev

AI coding assistants are powerful productivity enhancers, but they often lack the critical architectural and tribal knowledge unique to your organization. Cont3xt.dev solves this fundamental challenge by acting as a universal, single source of truth for your team's conventions, decisions, and ongoing work. This platform empowers every AI tool—from GitHub Copilot to Claude—to suggest code that strictly adheres to your internal standards, drastically reducing common context failures by up to 75% and accelerating development velocity.

Key Features

Cont3xt.dev provides the necessary infrastructure to standardize, share, and automate the application of team knowledge across all modern coding workflows.

💡 Universal Context via MCP Server

Connect once, and your context works everywhere. Cont3xt.dev utilizes the standard MCP (Multi-Context Protocol) to serve team knowledge instantly to compatible tools like Cursor, GitHub Copilot, and Claude. This eliminates the need for managing multiple, fragmented configuration files (e.g., .cursorrules, RULES.md) and ensures every tool operates from the same source of truth.

📝 Comprehensive Rules and Architecture Decisions (ADRs)

Create, organize, and prioritize critical team conventions, security policies, and architectural decisions. The platform allows you to define rules with specific file patterns (e.g., Applies to: auth/**) and priority levels (e.g., CRITICAL). Furthermore, you can document the why behind decisions (e.g., why PostgreSQL was chosen over MongoDB), linking directly to related PRs and tracking decision status.

⚙️ Automatic Knowledge Capture and GitHub Integration

Stop losing valuable knowledge in review threads. Cont3xt.dev integrates directly with GitHub, automatically analyzing PR discussions and code review comments. It converts these insights into actionable, shared rules, ensuring that important decisions and patterns are immediately codified and accessible to the AI, rather than being trapped in senior developers’ heads or Slack threads.

🤝 Real-Time Team Coordination

Gain crucial visibility into the active work of your team. The coordination features show who is working on which parts of the codebase in real-time, allowing AI assistants to factor in concurrent development efforts. This proactive approach helps prevent merge conflicts before they happen, saving developers valuable time spent resolving redundant work.

🎯 Smart Context Filtering

Ensure token budgets are respected while maximizing relevance. Cont3xt.dev uses AI-powered relevance scoring to serve only the most applicable rules and context based on the file or code segment you are actively working on. This priority-based selection ensures your AI assistant receives perfect, relevant knowledge without wasting valuable context window tokens.

Use Cases

Cont3xt.dev transforms several key areas of the software development lifecycle, moving implicit tribal knowledge into explicit, actionable code assistance.

1. Accelerating Developer Onboarding

New developers often take six or more weeks to fully internalize team conventions, leading to early mistakes and high senior developer overhead. By integrating Cont3xt.dev, the AI assistant immediately guides new hires according to established rules. This instant context means new developers are productive from day one, writing code that adheres to standards without needing constant oversight.

2. Enforcing Critical Security and Coding Standards

Instead of catching the same mistakes repeatedly in PR reviews, Cont3xt.dev proactively prevents them. For instance, if your team has a CRITICAL rule requiring bcrypt with a cost factor of at least 12 for password hashing, the AI will immediately flag and suggest corrections if a developer attempts to use a deprecated approach like MD5, drastically lowering the context failure rate.

3. Reclaiming Senior Developer Time

Senior developers typically spend 5 to 10 hours per week answering the same architectural questions ("How do we handle caching?"). By formalizing these answers into accessible Architecture Decisions and a shared Prompt Library, the AI assistant can handle most routine inquiries, freeing senior talent to focus on complex building tasks and strategic initiatives.

Conclusion

Cont3xt.dev is the necessary layer that bridges the gap between powerful, generalized AI coding tools and your team's specific, critical knowledge base. By providing universal context, automated knowledge capture, and proactive conflict prevention, you can ensure higher code quality, faster onboarding, and significantly improved team productivity.
