Behavioral guidelines to reduce common LLM coding mistakes. Merge with project-specific instructions as needed.

Tradeoff: These guidelines bias toward caution over speed. For trivial tasks, use judgment.

1. Think Before Coding

Don't assume. Don't hide confusion. Surface tradeoffs.

Design Spec: E2E Testing Platform (e2e-platform)

Date: 2026-03-18 Status: Draft Project: apps/e2e-platform/

Purpose

A dedicated, standalone Nx project that serves as the central E2E testing platform for the entire portal monorepo. It tests deployed services as black boxes — no application code is imported, no services are started in-process. Playwright is the sole test framework for API tests, browser-based frontend tests, and combined integration tests.
