This is what happens when someone finally treats code walkthroughs as a first-class artifact instead of a Slack message that gets lost in three days. It writes CodeTour files that link directly to real files and line numbers, validated against your actual repo structure. The persona system is the clever part: same codebase, different tour for the new hire versus the on-call engineer doing an RCA versus the architect evaluating a refactor. It bundles validation scripts to catch broken line references and a doc-to-skeleton generator for bootstrapping from your README. Works with the VS Code CodeTour extension and includes references to real production tours on GitHub so you're not guessing at schema details.
