Description

A strong bundle of core competencies for software engineering, with good coverage of a large portion of the SDLC - from planning, reviewing, testing, debugging... Well written, well organized, and adaptable. The author refers to them as "superpowers", but many of them are just consolidating engineering best practices - which sometimes does feel like a superpower when working with Claude Code.
