A catchy title, but in fact a question. I was trying to understand and optimize claude code for max token efficiency and found out an interesting thing: the subagents spawned by main agent on sonnet model, like opus models use tool search for mcp discovery, they are initialized lazily, which saves tokens. the haiku model subagants instead does not know how to use tool search and all mcps are loaded into context eagerly. So, if a user for example has a big amount of mcps, and runs his lightweight tasks on haiku subagent - wouldn’t he lose more quota than same task on sonnet agent? Did anyone try to measure the difference? submitted by /u/PlaneFinish9882
