21The agentic loop is powered by two components: [models](#models) that reason and [tools](#tools) that act. Claude Code serves as the **agentic harness** around Claude: it provides the tools, context management, and execution environment that turn a language model into a capable coding agent.

200* **Type a correction and press `Enter`** to send it without stopping the running tool. Claude reads it as soon as the current action completes and adjusts before deciding its next step.
200* **Type a correction and press `Enter`** without stopping Claude. The message shows as queued above the input box. If Claude is running tool calls, it reads the message as soon as those calls finish, within the same turn, and adjusts before its next step. [Queue messages while Claude works](/docs/en/interactive-mode#queue-messages-while-claude-works) covers when other queued entries are sent.
