# CLI Reference
every command, key, and flag

Every shell subcommand, every TUI slash command, every keybinding. The in-app `/help` and `/keys` panels are the live source of truth — this page is the printable companion.

## Shell subcommands

Run `carboncode --help` (or any subcommand with `--help`) for the full flag list. Headline subcommands:

Command | What it does
--- | ---
`carboncode code [dir]` | Code-mode TUI — file edits, plan mode, edit-gate, project-scoped sessions
`carboncode chat` | Chat-only TUI — no filesystem access, no code mode
`carboncode run <task>` | Headless run — read prompt, execute, exit (CI-friendly)
`carboncode setup` | Interactive first-run config (API key, language, theme)
`carboncode sessions [name]` | List or open a saved session
`carboncode prune-sessions` | Drop sessions older than `--days N`
`carboncode replay <transcript>` | Re-render a JSONL transcript without calling the model
`carboncode diff <a> <b>` | Compare two transcripts (cost / cache / tokens)
`carboncode events <name>` | Tail the event log for a session
`carboncode stats [transcript]` | One-shot cost / cache breakdown
`carboncode doctor` | Health check — API reach, config, hooks, project
`carboncode commit` | `git add -A && git commit` with an LLM-written message
`carboncode mcp <list|search|install|inspect|browse>` | MCP server management
`carboncode index` | Build the local semantic index (Ollama or OpenAI-compatible embeddings)
`carboncode version` / `carboncode update` | Version info + upgrade hint

### Notable runtime flags (chat / code)

Flag | What it does
--- | ---
`--no-session` | Ephemeral run — nothing is persisted
`--session <name>` | Resume / pin to a named session
`--continue` | Resume the most recent session for this workspace
`--new` | Force a fresh session even if one exists
`--budget <usd>` | Per-session USD cap — warns at 80%, refuses next turn at 100%
`--preset <auto|flash|pro>` | Model bundle (auto-escalation, locked flash, locked pro)
`--mcp <spec>` | Attach an MCP server for this run (repeatable)
`--no-config` | Ignore `~/.carboncode/config.json` for this run
`--no-dashboard` | Don't auto-start the embedded web dashboard
`--no-alt-screen` | Render to scrollback instead of the alt-screen buffer (preserves chat in shell history; legacy mode, can ghost on resize)
`--no-mouse` | Disable DECSET 1007 (alternate-scroll); wheel reverts to native terminal scroll

## Slash commands

Type `/` mid-chat to open the picker. Aliases shown in parentheses. Code-mode-only commands marked (code).

### Chat ops

Command | What it does
--- | ---
`/help` (`/?`) | Show the full command reference inline
`/new` (`/reset`, `/clear`) | Start a fresh conversation (clear context + scrollback)
`/retry` | Truncate and resend your last message — fresh sample
`/compact` | Fold older turns into a summary (cache-safe). Auto-fires at 50% ctx; this is the manual trigger
`/stop` | Abort the current model turn (typed alternative to Esc)
`/btw <question>` | Ask a side question without changing the main conversation
`/copy` | Open vim/tmux-style copy mode — `j`/`k` navigate, `v` select, `y` yank to clipboard. The right answer for SSH / mosh / tmux where drag-select can't extend past the viewport

## Keyboard

Key | What it does
--- | ---
`Enter` | Submit the prompt
`Shift+Enter` | Insert a newline in the prompt
`↑` / `↓` | Scroll chat history (mouse wheel routes here too)
`Ctrl+P` / `Ctrl+N` | Previous / next prompt history · cursor up / down in a multi-line draft. In a submitted-plan confirmation modal, `Ctrl+P` expands/collapses full plan details
`Ctrl+A` / `Ctrl+E` | Jump to start / end of the current line
`Ctrl+W` | Delete the word before the cursor
`Ctrl+U` | Clear the entire prompt buffer
`Tab` | Complete @-mention · drill folder · accept slash command
`Shift+Tab` | Edit-gate: toggle review ↔ AUTO mode
`Esc` | Dismiss picker · abort the running model turn
`Ctrl+C` | Abort the running model turn (NOT copy — see clipboard)
`PgUp` / `PgDn` | Scroll chat history a page at a time. While plan details are expanded, scroll the bounded detail window
`End` | Jump chat to the most recent line

### Edit-gate (code mode)

Key | What it does
--- | ---
`y` / `n` | Accept / drop pending edits in the review modal
`Shift+Tab` | Toggle review ↔ AUTO (persisted across sessions)
`u` | Undo the last auto-applied batch (within the 5s banner)

## Mouse

Action | What it does
--- | ---
Wheel | Scrolls chat history (works on web / cloud / SSH terminals too)
Drag | Selects text natively — no modifier needed
Right-click | Terminal-native (e.g. paste menu on Windows Terminal)

Carbon Code sets DECSET 1007 (alternate-scroll) only — wheel events translate to ↑/↓ keypresses for the app, but native click/drag selection is left untouched. Pass `--no-mouse` to opt out entirely.

## Copy / paste

The default path is terminal-native. Drag to select, then use your terminal's normal copy keys:

Action | How
--- | ---
Select text | Drag — terminal-native (no modifier)
Copy | `Ctrl+Shift+C` (Win / Linux) · `Cmd+C` (macOS) — or auto-copy-on-select if your terminal does it
Paste | `Ctrl+V` or `Ctrl+Shift+V` (Win / Linux) · `Cmd+V` (macOS)
Multi-line paste | Bracketed paste — pastes stay one block, no auto-submit on intermediate newlines

### When drag-select doesn't work

In SSH / mosh / tmux, the alt-screen buffer prevents the terminal from extending the selection past the visible viewport — there is no scrollback above the alt-screen to drag into. Two fixes:

1. `/copy` — open vim/tmux-style copy mode in-app. Snapshots the current chat to a navigable buffer; `y` yanks to clipboard via OSC 52 (with a temp-file fallback for terminals that don't support it).
2. `--no-alt-screen` — render to shell scrollback instead. Drag-select then works terminal-natively (the chat content is real lines in the scrollback above your cursor). Trade-off: redraw can ghost on resize.

### `/copy` — copy mode keys

Key | What it does
--- | ---
`j` / `↓` | Cursor down one line
`k` / `↑` | Cursor up one line
`PgUp` / `PgDn` | Page up / down
`g` / `G` | Jump to top / bottom
`v` | Start (or cancel) selection at the cursor
`y` / `Enter` | Yank selection to clipboard, exit
`q` / `Esc` | Quit without yanking

`y` with no active selection yanks just the current line. The yank goes through OSC 52 first (works through SSH, mosh, tmux with `set -g set-clipboard on`); content larger than 75 KB falls back to a temp file whose path is printed on exit.
