5656* **Attribution**: recent usage attributed to skills, subagents, plugins, and individual MCP servers, each shown as a percentage of the total. An MCP server's share counts only the requests that consumed one of its tool results. Before v2.1.222, after one call to an MCP server, Claude Code attributed every subsequent request to that server, overstating its share.
5757* **Behavior flags**: behaviors such as long context or cache misses, flagged when one accounts for 10% or more of recent usage.
58* **Loops**: a row for each of the heaviest [`/loop` or other scheduled tasks](/docs/en/scheduled-tasks) that ran recently, ordered by total tokens, with a count of the rest. Claude Code reports how often each task fires, how many times it ran, its total and per-run tokens, and when it last ran. Claude Code keys a row by the task's prompt, so a loop you stop and re-create stays one row. Requires Claude Code v2.1.242 or later.

59 * **What each row reports**: how often the task fires, how many times it ran, its total and per-run tokens, and when it last ran
60 * **Stopped and re-created loops**: Claude Code keys a row by the task's prompt, so a loop you stop and re-create stays one row

365367* **Long context**: Claude Code sends your full conversation with every request, and each time Claude uses tools it sends another request carrying that batch of tool results. With [prompt caching](/docs/en/prompt-caching), Claude Code re-reads that history at the [cached token rate](https://platform.claude.com/docs/en/about-claude/pricing), so a one-line question in a session that has been open all day still draws usage for the whole conversation. See [Manage context proactively](#manage-context-proactively) for ways to keep your context small
366368* **Cache misses**: your first message after a break longer than the [cache lifetime](/docs/en/prompt-caching#cache-lifetime) misses the cache and reprocesses your full context. The lifetime is an hour on a subscription and drops to five minutes once you're drawing on [usage credits](https://support.claude.com/en/articles/12429409-extra-usage-for-paid-claude-plans); on an API key or cloud provider, it's five minutes by default. To keep the one-hour lifetime while drawing on usage credits, [choose the TTL yourself](/docs/en/prompt-caching#choose-the-ttl-yourself)
367* **Scheduled tasks**: a [scheduled task](/docs/en/scheduled-tasks) fires on its interval even while the session is idle, sending your full context each time
369* **Scheduled tasks**: a [session-scoped scheduled task](/docs/en/scheduled-tasks) fires on its interval even while the session is idle, sending your full context each time
368370* **Cross-session messages**: Claude Code delivers a [message from another of your sessions](/docs/en/cross-session-messaging) as a new turn when this session sits idle, sending your full context each time. To hold inbound messages instead of delivering them, set [`crossSessionInbound`](/docs/en/settings-reference#crosssessioninbound) to `hold`
369371* **Goal check-ins**: while background work keeps an active [goal](/docs/en/goal) waiting, Claude Code [asks Claude to check on that work](/docs/en/goal#background-work-defers-evaluation) even when the session sits idle, starting a new turn that sends your full context. Claude Code starts at most three idle check-ins per goal between your prompts. Before v2.1.246, idle check-ins were uncapped. To turn check-ins off, set [`CLAUDE_CODE_GOAL_CHECKIN_MINUTES`](/docs/en/env-vars) to `0`. Idle check-ins require Claude Code v2.1.236 or later
370372* **Subagents and workflows**: every subagent, and every agent a [dynamic workflow](/docs/en/workflows#cost) spawns, sends its own requests on top of the main conversation's. The [attribution breakdown](#plan-usage-breakdown) shows the subagent share
