Hide built-in commands from the model with disableBundledSkills to reclaim context

Claude Code Changelog v2.1.169 (Releasebot)·medium signal

Claude Code v2.1.169 added a disableBundledSkills setting that stops the bundled skills/commands from being advertised to the model, trimming the always-on token overhead when your project only uses custom skills. Combined with the new /reload-skills and /reload-plugins commands, you can iterate on extensions mid-session without restarting and losing prompt cache. This is a direct lever on the 'distraction' failure mode — fewer irrelevant tool descriptions competing for the model's attention.
