you watched one tool result scroll past for about ten seconds and moved on
that result had a size limit, and you are not the one who set it
the default ceiling is twenty five thousand tokens,
but a server declares its own in the same response that lists its tools,
up to five hundred thousand characters,
and its number beats the one in your settings
so the package you installed decides how much of your context a single call is allowed to eat
you can set the variable
it can overrule you in the handshake where it tells you its name
you are not running the tools
you are hosting them
