User-facing plugin wrapping 29 intelligence MCP tools (neural_*, hooks_intelligence_*, routing hooks, SONA/MicroLoRA) into skills, commands and the 4-step RETRIEVE → JUDGE → DISTILL → CONSOLIDATE pipeline, plus a function-hook mod (write guard, reset confirm, /intelligence-mod).

ruflo as a Claude Code mod (function hooks, ADR-404): in-process prompt routing, edit learning signals, tighten-only tool checks from ruflo policy, the cost-tracker budget ladder, a mod trust gate for newly installed mods, and the $.ruflo noun other mods compose their status with. Opt-in and removable: the classic hook-handler hooks stay the default and take every event back whenever the mod is not loaded.
