You can also run Dev with a prompt as input:
dev "explain this codebase to me"dev --full-auto "create the fanciest todo-list app"That's it - Dev will scaffold a file, run it inside a sandbox, install any missing dependencies, and show you the live result. Approve the changes and they'll be committed to your working directory.
Below are a few bite-size examples you can copy-paste. Replace the text in quotes with your own task.
| ✨ | What you type | What happens |

You can give Dev extra instructions and guidance using AGENTS.md files. Dev looks for AGENTS.md files in the following places, and merges them top-down:
~/.code/AGENTS.md- personal global guidance (a legacy~/.codex/AGENTS.mdis also read if present)AGENTS.mdat repo root - shared project notesAGENTS.mdin the current working directory - sub-folder/feature specifics
For more information on how to use AGENTS.md, see the official AGENTS.md documentation.
Typing @ triggers a fuzzy-filename search over the workspace root. Use up/down to select among the results and Tab or Enter to replace the @ with the selected path. You can use Esc to cancel the search.
Paste images directly into the composer (Ctrl+V / Cmd+V) to attach them to your prompt. You can also attach files via the CLI using -i/--image (comma‑separated):
dev -i screenshot.png "Explain this error"
dev --image img1.png,img2.jpg "Summarize these diagrams"When the chat composer is empty, press Esc to prime “backtrack” mode. Press Esc again to open a transcript preview highlighting the last user message; press Esc repeatedly to step to older user messages. Press Enter to confirm and Dev will fork the conversation from that point, trim the visible transcript accordingly, and pre‑fill the composer with the selected user message so you can edit and resubmit it.
In the transcript preview, the footer shows an Esc edit prev hint while editing is active.
Generate shell completion scripts via:
dev completion bash
dev completion zsh
dev completion fishSometimes it is not convenient to cd to the directory you want Dev to use as the "working root" before running. Fortunately, dev supports a --cd option so you can specify whatever folder you want. You can confirm that Dev is honoring --cd by double-checking the workdir it reports in the TUI at the start of a new session.
