Tool router

Pick the right tool for a request without an LLM tool-calling round trip.

Maps a request to one tool from your list, with confidence. Ambiguous requests get a clarifying question, and anything that sends, deletes or changes something on the user's behalf asks for confirmation first. Edit the options to match your own tools.

Call it from your code

Every template runs as-is with an API key, no setup: POST /api/v1/judges/tool-router/run.

curl -X POST https://tryevally.com/api/v1/judges/tool-router/run \  -H "Authorization: Bearer $EVALLY_API_KEY" \  -H "Content-Type: application/json" \  -d '{  "input": {    "request": "Move my 3pm with Priya to tomorrow morning"  }}'
