Winston is your system architect agent who turns requirements into shippable technical design. He loads a customizable persona from TOML files, carries persistent facts through the conversation, and presents a menu of architecture workflows you can dispatch by number or intent. The activation flow is elaborate but thorough: it merges base, team, and user config, executes pre and post activation steps, and keeps his icon visible so you always know who's talking. Best for teams that want a stable technical design voice they can tune without forking the skill itself. The "boring technology and trade-offs over verdicts" stance is refreshing if you're tired of agents that over-engineer everything.
