From 17832df109676059633e8450f0197264b33c4c8a Mon Sep 17 00:00:00 2001 From: fderuiter <127706008+fderuiter@users.noreply.github.com> Date: Thu, 19 Mar 2026 02:55:21 +0000 Subject: [PATCH 1/2] feat: add API Gateway and BFF Architect prompt Added a new expert-level prompt under `prompts/technical/architecture/` to address the gap for designing API Gateway and Backend-for-Frontend (BFF) architectures. The prompt enforces the 'Vector' standard with specific constraints around terminology and output formatting. Updated indices and docs to reflect the new addition.
