Problem Statement

• Model-A is good at analyze and cheap, but it performs bad when coding.
• Model-B is strong at coding, but expensive.

What we want: We commit a task to claude, it start analyzing with Model-A but turn to Model-B when needing generating and executing code. After code generated/executed, it turn back to Model-A. The whole process happends without human involved.

Real Scenario: We are using claude code analyzing malware. This mission heavily costs tokens, so we are using a cheap model which is enough for analyzing but performs bad at coding. We hope that, we can make any setups, letting claude code auto turn to Model-B and turn back to Model-A like the way above.

Proposed Solution

Setup: setup models for specified tools/skills/subagents with config file or claude cli command.
