A GitHub App reviews every pull request the moment it opens, whether you wanted it to or not. commitbrief remote pr <id> reviews the one you point it at, when you run it — driven by your own gh auth, posting from your own account, with no server in between. This is the last integration in the series, and it's the one where the positioning is the architecture: who owns the trigger.
A hosted reviewer fires on a webhook. It runs on someone else's infrastructure, holds an installation token for your repo, and decides on its own schedule. The CLI inverts all three: it runs on your machine, borrows the GitHub auth you already have, and fires exactly when you decide a PR is worth a second pass. Same review engine as the terminal and the agent paths — different trigger, and the trigger is the whole point.
TL;DR
commitbrief remote pr 42 fetches a PR's diff through gh, reviews it, and posts findings as inline comments — from your account, on your command.
It performs no HTTPS calls of its own. Every GitHub round-trip goes through your gh CLI, which already holds your auth.
