Adr 011 Dynamic Routing Prompt

# ADR-011: Dynamic Router Prompt

## Status

Accepted (2025-Q4)

## Context

ClawAI's AUTO routing mode uses a local Ollama model to classify user messages and select the best AI provider/model. Initially, the router prompt was a static template listing all available models and their capabilities.

This static approach broke down as the model catalog grew:

- When a user installed a new coding model, the router did not know about it
- When a model was deleted, the router still tried to route to it, causing failures
- Adding a new model category required updating the prompt template manually
- The prompt listed models that were not installed, wasting tokens and confusing the router

## Decision

Build the router prompt dynamically at runtime based on the currently installed and healthy models. The `PromptBuilderManager` in the routing service fetches installed models from the ollama-service internal API, groups them by category, and constructs the routing prompt.
