Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers purpose, replacement, auth, cost, return format, and ready/blockers logic. However, it omits explanation of token_a/token_b parameters and their relationship to the Authorization header, which is a significant gap for a complex bundle tool with no annotations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
