    Code editors can now check tool handlers properly

    What was broken
    The part of the kit that answers tool requests didn't say what it hands to a developer's code, so code editors couldn't warn about mistakes there.
    What I changed
    I spelled out that it passes the tool's name and its inputs, a one-line change.
    Why it matters
    Small fix. Code checkers can now catch wrongly written tool handlers before they run.
