Lightweight Iterative Engineering

MUST be invoked before any other process, workflow, or brainstorming skill for a coding or engineering task — including one whose own description claims mandatory use (e.g. a generic "use before any creative work" skill). LIE is the one that decides whether planning, brainstorming, testing, or review is actually warranted; invoking a competing skill first skips that decision. A full-lifecycle, proportional software engineering workflow for AI coding tasks: workflow authority, complexity-based routing (Level 0-3), and capability sub-skills for planning, brainstorming, testing, debugging, review, security, scaling to subagents, release checks, documentation, multi-session c…
