Demonology.Demonology is a local-first CLI/TUI for steering LLMs (e.g. Qwen-3-Coder-30B via llama.cpp) with a demonology-themed UI. It offers stable tool-calling, a modular framework (filesystem, code exec, web search, git, shell), rich theming, and an opt-in permissive mode. Mystical vibe, pragmatic engineering.
