Gentle-AI is NOT an AI agent installer. It adapts the agent runtime(s) already on your machine; it never installs one for you. If a selected agent isn't detected, Gentle-AI refuses and names the exact command you'd run yourself instead. It is an ecosystem configurator that equips the AI coding agent(s) you already use with persistent memory, Spec-Driven Development (SDD), curated skills, MCP servers, model routing, a teaching-oriented persona, and bounded native review.
