The Swiss Army Knife Trap: Why Wrapping Every API as an Agent Tool Backfires

Description and use

<p>You've got two ways to connect an agent to your backend, and each one breaks somewhere different.</p> <p>Wrap every endpoint as a tool and you keep flexibility: the agent can combine steps in ways nobody planned. It breaks when the job needs a long chain and the ordering rules live in the prompt. Build a few deep tools shaped around whole tasks and the steps run in code. That breaks when a job falls outside what you modelled. For exploratory or research agents, the flexibility can be worth the cost. For customer-facing automation that moves money, my default is deep tools.</p> <p>The idea c
