     OpenClaw maps this to `anthropic-beta: context-1m-2025-08-07` on requests.
 
+    `params.context1m: true` also applies to the Claude CLI backend
+    (`claude-cli/*`) for eligible Opus and Sonnet models, expanding the runtime
+    context window for those CLI sessions to match the direct-API behavior.

     <Warning>
     Requires long-context access on your Anthropic credential. Legacy token auth (`sk-ant-oat-*`) is rejected for 1M context requests — OpenClaw logs a warning and falls back to the standard context window.
