Personal Data Tools: native Calendar, Reminders, Contacts (hidden pending Apple TCC fix in beta), and Location & Maps access via EventKit, Contacts framework, and MapKit. Write actions (create event/reminder, complete reminder) gate through an approval sheet. Four hardened-runtime entitlements added to oAI.entitlements; Info.plist usage strings added for all services. Personal Data section shows a β badge while Contacts is hidden. 2nd Brain always-trust: inline toggle on the Agent Skills row for the skill named "2nd Brain" skips the bash approval dialog when the command contains .brain_helper.py, gated by three runtime checks in MCPService. Research agents: spawn_research_agents tool runs up to 5 concurrent read-only sub-agents (read_file, list_directory, search_files, web_search — no write, no bash, no nesting). Bounded by maxConcurrentAgents setting (default 3) and a hard ceiling of 8 tasks. Added items field to Tool.Function.Parameters.Property for JSON Schema array support; wired into AnthropicProvider.convertParametersToDict. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
