Factory Droid 0.199.0: SDK custom system prompts, managed BYOK defaults, explorer tool expansion
The TypeScript SDK now supports custom system prompts that persist across session resumes. Org admins can set managed BYOK model defaults and apply model policies to service accounts. The built-in explorer droid can use all read-only tools (commands, web search, MCP) while file edits stay blocked. Question prompts gain keyboard controls, Mermaid diagrams render natively, and long sessions render with less lag.
