<h2 id="questions-answers">Questions & Answers</h2>
<p><strong>Q: How do I add a new LLM provider?</strong> A: Implement the
Provider interface (provider.go:112) and register with ProviderFactory
(provider.go:339)</p>
<p><strong>Q: How does model selection work?</strong> A: See
ModelManager.SelectOptimalModel() in model_manager.go:75 - scores based
on 6 factors</p>
<p><strong>Q: How is prompt caching implemented?</strong> A: Automatic
in anthropic_provider.go:48 - system messages and last message cached
with ephemeral cache control</p>
<p><strong>Q: How does distributed execution work?</strong> A: SSH
worker pool (ssh_pool.go:17) with auto-installation, health monitoring,
and capability-based assignment</p>
<p><strong>Q: What’s the MCP protocol flow?</strong> A: WebSocket
connection → Session creation → Tool list → Tool execution → Broadcast
notifications</p>
