What probably matters to youSection of the release
What
The check that decides whether the todo/task tracking tools are available dropped a remote feature-flag lookup and an associated fallback branch it previously relied on. Now availability is decided purely by local conditions: it's enabled if certain internal checks pass, if the model's capability string is missing or matches specific known patterns, or if the environment variable CLAUDE_CODE_ENABLE_TODO_TOOLS is explicitly set to true, with no separate remote feature-flag fallback anymore.
Why
This makes todo/task tool availability depend only on local, inspectable conditions (the model in use and the CLAUDE_CODE_ENABLE_TODO_TOOLS environment variable) rather than a remote flag fetched from Anthropic's servers.
