Assemble a safe Git command preview from an operation, flags, paths, and message.
The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.
Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.
Selected operation, flags, paths, and message text are shell-quoted and assembled into a command preview. The builder emits text only and does not run against a repository.
Action: commit Files: src/auth.ts src/login.ts Message: add OAuth2 login flow
git add src/auth.ts src/login.ts && git commit -m "add OAuth2 login flow"
Runbooks, teaching examples, and CI templates build Git commands.
