THE MODEL ROUTER STARTER KIT
Teach your AI to pick the right brain and effort for every task.

WHAT IS IN HERE
- MODEL_ROUTING.md   the one rules file your assistant reads to make the choice
- agents/writer.md       a creative and voice helper (the writer)
- agents/builder.md      a long-and-heavy work helper (the builder)
- agents/analyst.md      a reasoning and checking helper (the analyst)
- agents/fast-worker.md  a cheap high-volume helper (the fast worker)

HOW TO INSTALL (Claude Code)
1. Copy the four helper files into your agents folder:
     cp agents/*.md ~/.claude/agents/
   (make the folder first if it does not exist: mkdir -p ~/.claude/agents)
2. Copy the rules file where your assistant will read it:
     cp MODEL_ROUTING.md ~/.claude/MODEL_ROUTING.md
3. Add one line to your ~/.claude/CLAUDE.md so it is applied every session:
     Before any substantial task, choose the model and effort using ~/.claude/MODEL_ROUTING.md.
That is it. From now on your assistant matches the tool to the task on its own.

MAKE IT YOURS (two edits worth doing)
- Your privacy rule. Open MODEL_ROUTING.md and set what counts as private for YOU
  (client records, health notes, anything you are under a duty to protect). That is
  the one rule that sits above all the others.
- Your voice. Open agents/writer.md and replace the voice notes with how YOU sound,
  so the writer speaks like you and not like a chatbot.

A NOTE ON MODELS
The helper files name model tiers, not exact product names, so they keep working as
models change. If your plan does not have the top creative model yet, the writer
helper simply falls back to your strong default, and you can still draft creative
pieces in a chat window with the best writing model selected, then bring them back.

Nothing here sends anything anywhere on its own. It only decides which brain thinks
about a task and how hard. You stay the one who approves the work.
