275If a tool is running when you press `←`, Claude Code waits for it to finish before backgrounding, and Claude continues the response in the background session. Press `←` again to background immediately instead of waiting. When in-flight work can't carry over to the background session, Claude Code shows the `Background this session?` dialog first, the same as with [`/background`](#from-inside-a-session).275If a tool is running when you press `←`, Claude Code waits for it to finish before backgrounding, and Claude continues the response in the background session.

282* **You stop the turn**: Claude Code cancels the switch and shows `Backgrounding cancelled — the turn was stopped.` For example, the turn stops when you [interrupt Claude with `Esc`](/docs/en/interactive-mode#general-controls) or select **No** [without a comment](/docs/en/permissions#add-a-comment-when-you-answer-a-permission-prompt) on a permission prompt from the main conversation, or press `Esc` on a question Claude asks there.

283* **A queued message can't move**: messages you [queued while Claude was working](/docs/en/interactive-mode#queue-messages-while-claude-works) move to the background session with the conversation. When one of them can't, the session stays in the foreground and Claude Code shows a notice such as `Cannot open agents — 1 queued message can't move to the background.

285When Claude Code backgrounds the session, either after about ten seconds or after you press `←` again, it stops a shell command that Claude is still running in the foreground. Claude Code doesn't show the `Background this session?` dialog for that command. In the background session, Claude has no record that the command started, so Claude may run the command again. To keep the command running when the session moves, press `Ctrl+B` to [turn it into a background command](/docs/en/interactive-mode#background-bash-commands) while Claude Code is still waiting.

463Backgrounding starts a fresh process that resumes from the saved conversation, and in-flight work moves to it: running background shell commands, backgrounded subagents, dynamic workflows, scheduled tasks you created with [`/loop`](/docs/en/scheduled-tasks), and Claude's [automatic replies to artifact comments](/docs/en/artifacts#let-claude-reply-to-comments-on-its-own) all carry over and keep running there. A subagent moves together with everything it started, so it carries over only when all of that work can move too. To stop in-flight work instead of carrying it over, set the [`CLAUDE_DISABLE_ADOPT=1`](/docs/en/env-vars#variables) environment variable; Claude Code then asks you to confirm before backgrounding.465Backgrounding starts a fresh process that resumes from the saved conversation, and in-flight background work moves to it: running background shell commands, backgrounded subagents, dynamic workflows, scheduled tasks you created with [`/loop`](/docs/en/scheduled-tasks), and Claude's [automatic replies to artifact comments](/docs/en/artifacts#let-claude-reply-to-comments-on-its-own) all carry over and keep running there.

465When a [dynamic workflow](/docs/en/workflows) still has subagents running, Claude Code asks before backgrounding with the `Background this session?` dialog, which says how many subagents would restart. Choose `Stay` to let them finish first. If you confirm, Claude Code replays the run in the background session: subagents that were still running start over from the beginning, so the tokens they used so far are spent again. See [Resume after a pause](/docs/en/workflows#resume-after-a-pause) for which completed subagents return their saved results and which run again.467When a [dynamic workflow](/docs/en/workflows) still has subagents running, Claude Code asks before backgrounding with the `Background this session?` dialog, which says how many subagents would restart.

79When the request for your plan limits fails, most often because the usage endpoint is rate limited, `/usage` shows the last usage bars it loaded on this machine within the past 60 minutes, along with a `Showing last-known usage` note stating how long ago that data was fetched. Press `r` to retry; a successful retry replaces the last-known bars with fresh data. Without a snapshot from the past 60 minutes, `/usage` reports that the usage endpoint is rate limited and offers the same retry shortcut.

81### Read the token count beside the spinner

82 

83While Claude works in the main conversation, the line beside the spinner can end with an elapsed time and a token count, as in `Deciphering… (10m 27s · ↓ 5.5k tokens)`. It is a live, approximate count of the output the current turn has produced so far. The arrow beside the count points down while output arrives or tools run.

84 

85* **What it covers**: output the turn generates, such as the text and tool calls Claude streams back, its thinking, and the output of subagents that run in the [foreground](/docs/en/sub-agents#run-subagents-in-foreground-or-background)

86* **What it leaves out**: what Claude Code sends to the model, so your prompt, the conversation history, and the rest of your context don't move it

87* **When it resets**: at the start of each turn, and when Claude Code [compacts the conversation](/docs/en/prompt-caching#compacting-the-conversation)

88* **When it stays hidden**: until output starts arriving, when the row is too narrow to fit it, and in [screen reader mode](/docs/en/accessibility)

89 

90It won't match the `Usage by model` output figures in the `/usage` Session block, which add up the whole session rather than one turn. It also differs from the token count [verbose mode adds](/docs/en/statusline#notifications-share-the-status-line-row), because that count measures the size of your context rather than one turn's output.

It analyzes your recent sessions on this machine and writes an HTML report covering what you work on, friction points such as misunderstood requests or buggy code, and suggestions for using Claude Code more effectively. A single run analyzes up to 200 sessions it hasn't seen before and skips very short ones. When sessions are left out, the report header shows the analyzed count with the total in parentheses, for example `200 sessions (412 total)`.94Run [`/insights`](/docs/en/commands#all-commands) for a report on how you work rather than how many tokens you've used.

By default, Claude Code assumes a gateway dropped the header from an otherwise unmodified response, so it decodes the body and streaming keeps working. Set this only for a gateway that also re-emits the stream as server-sent events; Claude Code then reads the header-less body as server-sent events instead.

Without this variable, when a response carries a different content-type, Claude Code fails the request with an error naming that type, which means a [gateway or proxy is transforming the response](/docs/en/amazon-bedrock#streaming-errors-behind-a-gateway-or-proxy).

Affects only that handoff: backgrounding a session with `←` or [`/background`](/docs/en/agent-view#from-inside-a-session) still carries in-flight work over, and `CLAUDE_DISABLE_ADOPT` turns off both.

By default, on macOS and Linux, Claude Code terminates background shells when the operating system reports critical memory pressure and the session has been idle for 30 minutes with no turn or subagent running.
