This generates Salesforce permission set XML files with all the pieces you'd expect: object CRUD, field-level security, user permissions, tab visibility, and Apex access. The documentation is thorough about gotchas that will break your deployment, especially the critical one about required fields (they can't appear in fieldPermissions at all, which the platform won't tell you until deploy time). It covers naming conventions for custom versus standard tabs and includes newer stuff like Agentforce agent access. If you're hand-writing permission sets or need Claude to scaffold them correctly instead of debugging mysterious deployment failures, this gives it the guardrails to do it right the first time.
