Found the issue. Here's what's happening:

Bug: alwaysThinkingEnabled Ignored

https://github.com/anthropics/claude-code/issues/10623 reports that alwaysThinkingEnabled: true is being completely ignored - thinking blocks aren't appearing despite the setting being enabled.

Related Problems

• https://github.com/anthropics/claude-code/issues/12311 - Auto-compact fails with Opus 4.5 extended thinking

Workarounds

1. Manual Tab toggle - Press Tab at the start of each session to enable thinking mode manually (sticky per-session)
2. Environment variable - Set MAX_THINKING_TOKENS in your shell config:

export MAX_THINKING_TOKENS=10000

1. Use prompt keywords - Include "think" or "think hard" in your prompts to trigger thinking for specific requests

The alwaysThinkingEnabled setting appears to be broken in recent releases. The Tab toggle or environment variable are your best bets until they fix it.
