Unclear Nothing has been read yet about how the tengu_lucid_anchor flag is set for any account, so it's unknown whether resets are currently being forced or avoided.

What

When tools are added partway through a conversation, Claude Code's server-side continuation planner decides whether to keep using the same underlying thread or reset and start a new one. A new check now controls this: if a flag called tengu_lucid_anchor is off, adding tools mid-conversation still forces the thread to reset rather than continue.

Why

This means whether tool additions can continue smoothly in the same thread, instead of forcing a reset, currently depends on this flag's setting.
