18811884* Run `/compact` to summarize earlier turns and free space, or `/clear` to start fresh. If `/compact` answers `Not enough messages to compact.`, the conversation is a single exchange with nothing earlier to summarize, so the space is taken by that one prompt and what Claude Code sends with every request: run `/clear` and resend with less pasted text or smaller attachments, or reduce the tool definitions and memory files using the steps below
18821885* Run `/context` to see a breakdown of what is consuming the window: system prompt, tools, memory files, and messages
1883* Disable MCP servers you are not using with `/mcp disable <name>` to remove their tool definitions from context
1884* Trim large `CLAUDE.md` memory files, or move instructions into [path-scoped rules](/docs/en/memory#path-specific-rules) that load only when relevant
1885* Subagents inherit every MCP tool definition from the parent session, which can fill their context window before the first turn. Disable MCP servers you are not using before spawning subagents.
1886* Auto-compact is on by default and normally prevents this error. If you turned it off in `/config` or with [`DISABLE_AUTO_COMPACT`](/docs/en/env-vars), turn it back on. If you keep it off, run `/compact` yourself before the window fills.

1892`/context` shows this warning at the top of its output when the conversation has grown past the model's context window. Requests fail with [`Prompt is too long`](#prompt-is-too-long) until you free space. An interactive session shows that error as the `Context limit reached` line.
