The "Chat" Trap
We are currently stuck in the "CMD.EXE" era of AI. The chatbox is a command line interface that pretends to be a conversation, and it fails at repeatability.
1. Prompt Drift
You craft the perfect prompt on Tuesday. On Friday, you try to recreate it, but you forget one specific instruction. The output changes. Reliability collapses.
2. The Search Black Hole
Trying to find "that one CodePen I generated three weeks ago" in a linear chat history is a nightmare. Chat logs are not a file system.
3. No State
Chat is ephemeral. Real software needs state. It needs to know "this is the current draft," not "here is a wall of text from 5 minutes ago."
PART II: THE SOLUTION
Encapsulated Micro-LLM Apps
The solution is to stop treating AI as a conversational partner and start treating it as a **component engine**. We build "Capsules."
The Capsule Triad
- Input Schema: Strictly typed arguments (e.g., "Code snippet", "Target Language").
- System Prompt: The frozen, perfected instructions that never drift.
- Output Renderer: A UI component specifically designed to view the result (e.g., a Syntax Highlighter, a Chart, a Table).
By saving this triad to a database, we create a Tool. This tool is repeatable, searchable, and shareable.
The Toolmaker
You don't need to code these tools manually. The **Toolmaker** agent accepts a natural language description ("Make a tool that converts Python to Rust and explains the memory safety differences") and generates the configuration instantly.
PART III: TECHNICAL STACK
Multimodal & Generative UI
To make this work, we need speed and strictness.
Gemini 2.0 Flash Lite
We use this for the "Eyes." Its multimodal native capabilities allow us to drop screenshots or mockups into a tool content.
Mistral / Devstral
We use this for the "Hands." Its superior code generation logic ensures the tools work as expected.
Generative UI (GenUI)
Standard UI is static. Chat UI is text. GenUI is the middle ground: UI that spawns based on the data.
The Risk: Hallucinated interfaces (AI trying to render a component that doesn't exist).
The Fix: We implementation strict Zod schemas that force the AI to choose from a registry of valid components (Charts, Tables, Markdown, CodeBlocks). If it tries to invent a widget, the validation layer catches it and falls back to raw text.
