How do you deal with the different APIs/Tooluse schema in a custom build? As other people have mentioned, it's a bigger undertaking than it sounds.

you're wasting valuable context with approaches like that

save it for more interesting tasks

Are you saying that json schema takes less tokens?

I'm saying that having tools/subagents is less tokens

For example, instead of a JSON schema in your prompt, use an Open API subagent with API tools to keep your primary contexts clean
