## Resource

A deep dive into the evolving landscape of web development, focusing on the Model Context Protocol (MCP) and the future of streaming HTML. The discussion explores how new standards can automate developer experience and optimize page rendering.

## Highlights
- Main idea: The Custom Elements Manifest (CEM) is a critical feature for web components, enabling better integration with design tools like Figma
- Practical takeaway: Use MCP (Model Context Protocol) at a project-specific level to avoid bloating the LLM context window with unnecessary tool definitions
- Failure mode: Over-installing MCP tools can quickly exhaust the available context window, degrading the performance of AI agents
- Technical insight: Modern web component architectures can leverage custom events and 'emit' patterns to create predictable, discoverable APIs
- Future trend: Declarative HTML streaming could allow for non-render-blocking content updates, where heavy elements load at the end of a stream without stalling the initial paint

## Topics

Web Components, Model Context Protocol, Custom Elements Manifest, HTML Streaming, AI Agents, Developer Experience, Frontend Engineering, DOM Rendering
