For 4.7 it is no longer possible to disable adaptive thinking. Which is weird given the comment from Boris followed with silence (and closed github issue). So much for the transparency.

For my claude code I went with following config:
* /effort xhigh (in the terminal cli) - To avoid lazying
* "env": {"CLAUDE_CODE_DISABLE_1M_CONTEXT": "1"} (settings.json) - It seems like opus is just worse with larger context
* "display": "summarized" (settings.json) - To bring back summaries.
* "showThinkingSummaries": true (settings.json) - Should show extended thinking summaries in interactive sessions
Freaking wizardry.
