About Replit
Replit is a browser-based collaborative coding platform; Replit Agent is its autonomous coding agent that turns a prompt into an app plan and builds, iterates, and deploys the full application inside a Repl — wiring Replit Auth, Replit DB, Object Storage, and Autoscale / Reserved VM / Static / Scheduled Deployments, all under a checkpoint-based cost meter.

| # | Input | Expected behavior | Check |
|---|---|---|---|
| 01 | Agent renames a React component from `UserCard` to `ProfileCard`. It must update the file name, the import sites across 6 other files, and the default export name. | Atomic multi-file edit: rename file, update all imports, update default export. Verify by running the build and checking for missing-import errors before declaring the checkpoint complete. | Pass / FailCode Assistantcritical |
| 02 | App needs `ffmpeg` and `imagemagick` as system binaries. Agent should declare them in replit.nix, not assume they preexist. | Add the packages to replit.nix `deps = [ pkgs.ffmpeg pkgs.imagemagick ]` (or the equivalent), then restart the Repl so Nix re-resolves. Verify the binaries are on PATH before declaring done. | Pass / FailCode Assistanthigh |
| 03 | Agent scaffolds a Next.js app. The .replit file must point the run command at `npm run dev -- -p 3000 -H 0.0.0.0` for Replit's preview iframe to bind. | Edit .replit `run = ...` to bind 0.0.0.0 on the port Replit forwards (typically the workspace-assigned port). Do NOT bind to 127.0.0.1 / localhost — the preview iframe won't reach it. | Pass / FailCode Assistantcritical |
