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 must add a `favicon.ico` referenced by `index.html`. The favicon is binary.	Use a workspace-appropriate binary write (e.g., generate the favicon as an actual binary file, not a base64 string written as text). Verify the file opens as a valid ICO. Do not commit a base64 placeholder labeled favicon.ico — the browser will fail to render it.	Pass / FailCode Assistantmedium
