 ### Automatic context management
 
-For long-running agentic tasks, the Python, TypeScript, and Ruby tool runners support automatic [compaction](https://platform.claude.com/docs/en/build-with-claude/context-editing#client-side-compaction-sdk), which generates summaries when token usage exceeds a threshold so the conversation can continue beyond context window limits. All three SDKs have deprecated this client-side option in favor of server-side [context editing](https://platform.claude.com/docs/en/build-with-claude/context-editing), which is available in every SDK. The Go, Java, C#, and PHP tool runners don't include client-side compaction.

Both SDKs have deprecated this client-side option in favor of [server-side compaction](https://platform.claude.com/docs/en/build-with-claude/compaction), which works with every SDK's tool runner through the `context_management` request parameter. The Python SDK (v1.0 and later) and the Go, Java, C#, and PHP tool runners don't include client-side compaction.
