Adds a TUI resume flow with an interactive picker and quick resume. - CLI: - --resume / -r: open picker to resume a prior session - --continue / -l: resume the most recent session (no picker) - Behavior on resume: initial history is replayed, welcome banner hidden, and the first redraw is suppressed to avoid flicker. - Implementation: - New tui/src/resume_picker.rs (paginated listing via RolloutRecorder::list_conversations) - App::run accepts ResumeSelection; resumes from disk when requested - ChatWidget refactor with ChatWidgetInit and new_from_existing; replays initial messages - Tests: cover picker sorting/preview extraction and resumed-history rendering. - Docs: getting-started updated with flags and picker usage. https://github.com/user-attachments/assets/1bb6469b-e5d1-42f6-bec6-b1ae6debda3b

Getting started
CLI usage
| Command | Purpose | Example |
|---|---|---|
codex |
Interactive TUI | codex |
codex "..." |
Initial prompt for interactive TUI | codex "fix lint errors" |
codex exec "..." |
Non-interactive "automation mode" | codex exec "explain utils.ts" |
Key flags: --model/-m, --ask-for-approval/-a.
Resume options:
--resume: open an interactive picker of recent sessions (shows a preview of the first real user message). Conflicts with--continue.--continue: resume the most recent session without showing the picker (falls back to starting fresh if none exist). Conflicts with--resume.
Examples:
codex --resume
codex --continue
Running with a prompt as input
You can also run Codex CLI with a prompt as input:
codex "explain this codebase to me"
codex --full-auto "create the fanciest todo-list app"
That's it - Codex 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.
Example prompts
Below are a few bite-size examples you can copy-paste. Replace the text in quotes with your own task. See the prompting guide for more tips and usage patterns.
| ✨ | What you type | What happens |
|---|---|---|
| 1 | codex "Refactor the Dashboard component to React Hooks" |
Codex rewrites the class component, runs npm test, and shows the diff. |
| 2 | codex "Generate SQL migrations for adding a users table" |
Infers your ORM, creates migration files, and runs them in a sandboxed DB. |
| 3 | codex "Write unit tests for utils/date.ts" |
Generates tests, executes them, and iterates until they pass. |
| 4 | codex "Bulk-rename *.jpeg -> *.jpg with git mv" |
Safely renames files and updates imports/usages. |
| 5 | codex "Explain what this regex does: ^(?=.*[A-Z]).{8,}$" |
Outputs a step-by-step human explanation. |
| 6 | codex "Carefully review this repo, and propose 3 high impact well-scoped PRs" |
Suggests impactful PRs in the current codebase. |
| 7 | codex "Look for vulnerabilities and create a security review report" |
Finds and explains security bugs. |
Memory with AGENTS.md
You can give Codex extra instructions and guidance using AGENTS.md files. Codex looks for AGENTS.md files in the following places, and merges them top-down:
~/.codex/AGENTS.md- personal global guidanceAGENTS.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.
Tips & shortcuts
Use @ for file search
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.
Image input
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):
codex -i screenshot.png "Explain this error"
codex --image img1.png,img2.jpg "Summarize these diagrams"
Esc–Esc to edit a previous message
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 Codex 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.
Shell completions
Generate shell completion scripts via:
codex completion bash
codex completion zsh
codex completion fish
--cd/-C flag
Sometimes it is not convenient to cd to the directory you want Codex to use as the "working root" before running Codex. Fortunately, codex supports a --cd option so you can specify whatever folder you want. You can confirm that Codex is honoring --cd by double-checking the workdir it reports in the TUI at the start of a new session.
