First-Pass Review on a Pull Request

Nothing to send, so it runs straight through.
Nothing in this job sends a message or pays for anything, so it works through to the end and tells you when it's done. If a step ever would, it's built to stop and ask you first.
If it hits a sign-in, you sign in yourself. It's built not to type your passwords or card numbers.
Before you ask it.
What do I say?
Press fn (Ctrl+Shift+Space on Windows and Linux) and ask out loud, in your own words, like "Review this pull request: flag edge cases and missing tests with inline comments and a summary."
Why is the second time faster?
The first time, it writes small JavaScript tools for GitHub and builds an API from each site's own buttons, forms and requests. After that it calls them directly, so the job runs in one go instead of click by click. It costs less and breaks less.
Will it send anything without me?
It's built to ask first before it sends a message or pays for anything, and to wait for your yes. It may not recognize every send or payment, so keep an eye on tasks that involve messages or money. It's built not to type your passwords or card numbers: you sign in yourself, and it picks up from there.
Why not just do it by hand?
Pull requests sit while reviewers are busy, and the first pass usually catches the same kinds of issues.
