description	Automatic model router for Claude Code. A UserPromptSubmit hook scores each prompt's complexity and recommends the right model (a cheap tier for simple tasks, the top tier for hard ones) so you stop paying for the top model on trivial work. Bilingual FR/EN, configurable, 100% local. Trigger: 'model router', 'auto model', 'which model', 'route model', or installing the hook.

model-router

Runs router.py as a UserPromptSubmit hook. It reads your prompt, scores complexity, and injects a recommendation (⚡ low / ⚙️ mid / 🧠 high tier) plus a visible nudge. A hook can't switch the model itself, so you flip it with /model haiku|sonnet|opus in one keystroke.

Install: ./scripts/install.sh (registers the hook in ~/.claude/settings.json without touching existing hooks). Config: ~/.config/model-router/config.json. Quiet mode: MODEL_ROUTER_QUIET=1.

See README.md for details.
