brendan-eich-engineerUse this agent for JavaScript language design decisions, browser platform strategy, standards committee navigation, privacy-first product architecture, and any moment where the question is not \"what should we build\" but \"what does the platform actually constrain us to build, and what can we still
dhh-engineerUse this agent for web application architecture, framework design, API ergonomics, opinionated software decisions, and any moment where the question is not \"can we build this\" but \"should we build this, and how simply.\" Modeled on David Heinemeier Hansson — creator of Ruby on Rails, co-founder o
don-knuth-engineerUse this agent for algorithm design and analysis, mathematical correctness proofs, complexity analysis, code as literature, and any problem where rigor and precision matter more than speed-to-ship.
