How to build efficient Agent ToolsMany engineers think of Agent Tools as functions, but they aren't. They are closer to user actions. Backed by a leave-one-out ablation study of Hypha's agent tools on a 55-question SQL retrieval eval: three financial data models, 300+ runs, three trials per case, on both the Codex SDK and the Claude Agent SDK.
More engineering posts on agent infrastructure, evals, and reliability are coming — most will run on the Hypha engineering blog and be indexed here. I post shorter notes on LinkedIn and X. Looking for the academic work? See Research.
