[1.3] — 2026-02-16
Added
- Platform Architecture section (new Chapter 2.5) — tool inventory matrix across browser (21 tools), desktop app (22+32 MCP), and mobile app (20+11 deferred)
- 3 new tool cards:
weather_fetch(Card 26),recipe_display_v0(Card 27),end_conversation(Card 28) - Platform-exclusive tools table showing which tools exist where
- Session instability warning (switching clients changes available tools)
- Fallback behavior documentation for each platform gap
- Settings & Connectors reference integrated into appendix
- 9 new figure placeholders (fig_14 through fig_22)
Changed
- Chapter 10 (Discovery Log): added mobile-only environment note — the discovery log was produced on mobile and is not reproducible on browser or desktop
- Chapter 2 (Architecture): rewritten to reflect three platform configurations instead of a single binary always-loaded/deferred model
- Card 5 (message_compose_v1): corrected primary button to "Send via Gmail", documented dropdown with "Open in Mail", added no-recipient-field note
- Card 4 (ask_user_input_v0): added "Something else" free-text option, Skip button, keyboard shortcuts, selection counter, drag handles, pagination
- Cards 17/18 (places): added markers mode sidebar details, itinerary mode routing, "Open route" Google Maps behavior, confirmation dialog inconsistency
- Card 6 (alarm_create_v0): confirmed mobile-only, added widget description with Italian locale, removed web/desktop speculation
- Card 7 (timer_create_v0): confirmed mobile-only, added widget description
- Card 1 (user_time_v0): added platform behavior differences (mobile returns exact time, desktop/browser states system date only)
- Card 3 (user_location_v0): confirmed mobile-only, documented two-layer permission system (Claude app + Android OS)
- Card 10 (chart_display_v0): confirmed mobile-only deferred, added app crash warning
- Card 25 (tool_search): major rewrite — browser has no tool_search, desktop finds MCP only, mobile finds consumer tools
- Cards 8–13 (Calendar suite): added mobile-only deferred status, Google Calendar connection requirement
- Appendix A: corrected availability matrix to reflect cross-platform testing results
- All response formats upgraded from (inferred) to empirically confirmed
- Figure numbering made sequential (fig_01 through fig_22, eliminated fig_14b)
Removed
- All (inferred) response format markers — every schema now confirmed through testing
- Speculative web/desktop availability claims for mobile-only tools
- Screenshot capture instructions from figure placeholders
