From 667aebf4000a658a11ed0634280c4d290bed5fe9 Mon Sep 17 00:00:00 2001 From: jsonbailey Date: Mon, 20 Apr 2026 12:46:06 -0500 Subject: [PATCH 1/5] feat: add root-level tools map with customParameters to AI Config types Adds LDTool interface and tools map (keyed by tool name) to completion and agent config types. The root-level tools map is distinct from model.parameters.tools[] which remains passable to LLM providers as-is.
