Q: What is a Claude Code skill and how does the Permission Set Group Composition skill fit in?

Tactical guidance for composing Permission Set Groups: layering permission sets, applying Mute Permission Sets to subtract narrow capabilities, sequencing the recalculation lifecycle, deletion order, and assignment-vs-activation lifecycle. Triggers: 'PSG composition', 'mute permission set', 'PSG recalculation', 'cannot delete permission set in PSG', 'PSG explosion', 'expired PSG assignment'. NOT for the strategic question of profile-vs-PSG architecture (see admin/permission-set-architecture). NOT for record-sharing or CRUD/FLS in Apex.

From the source SKILL.md

Activate this skill when the strategic decision to use Permission Set Groups is already made and the question is now tactical: which permission sets go into which PSG, when to add a Mute Permission Set, in what order to delete a PS that is wired into 50 PSGs, why a freshly assigned PSG still does not show its effective access, and how to keep PSG count from exploding. This is the operating manual that lives one floor down from admin/permission-set-architecture — that skill picks the access model, this skill makes the model survive contact with production.
