Both are the same shortcut: letting the source decide whether something is true so you don't have to check. Community Notes and real corrections help, but they show up hours after the post has already spread, so you end up doing your own checking either way.
Prompting Claude Opus 5.5 guides are useful, but the biggest gain for me was dropping the 'You are an expert…' role preamble and just giving it the repo context. Less roleplay, more files.
