guides.show

guides.show is a code review viewer that hosts chaptered walkthroughs of git diffs as portable HTML files or client-side encrypted links.

guides.show serves and hosts viewer links for Plannotator Guided Reviews. The tool takes a git diff and explains it in order of importance, grouping changes into chapters with short overviews and displaying the relevant files alongside the modifications. Guides can be generated via the plannotator-guide coding agent skill or downloaded directly from Plannotator as standalone HTML files. When shared online, guides are encrypted before leaving the user's machine, keeping the decryption key in the URL hash fragment so the server cannot read the contents. The hosting service runs as a self-hostable Cloudflare Worker with versioned, immutable viewer builds.
