Source Twin keeps a plain-Markdown mirror of a codebase beside the code, so people and coding agents can explain behavior, plan changes, and review implementation and tests together.

Why it surfaced

Its central idea is unusually concrete: follow a subscription-cancellation change from customer problem to reviewed code through linked behavior files, source, tests, and terminal results. The site makes a strong case for treating readable software guidance as a versioned, reviewable part of the repository rather than another dashboard or documentation silo.
