Persona conversations can now be anchored on a message in an SMS thread. Creating one snapshots the thread up to that message (via SMS-API) into the row; every turn appends it to the persona prompt with guidance to talk like a text thread rather than write an insight. Anchored turns get four tools: get_thread_messages (page the thread), look_at_message_image (local vision on an MMS photo), get_photos_near_time (library photos with tags and people) and look_at_photo (local vision on a library photo). The conversation list filters by contact_id. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

-- Anchor a persona conversation on a point in an SMS thread.
|
|
--
|
|
-- "Continue with persona" starts a persona chat from a long-pressed message
|
|
-- in the Messages screen. The conversation remembers which thread and which
|
|
-- message it grew out of, so the SMS screen can list the persona chats that
|
|
-- belong to a thread and the chat screen can show where it picked up.
|
|
--
|
|
-- `anchor_context` is a snapshot of the thread leading up to the anchor,
|
|
-- rendered once at creation and spliced into the system prompt on every
|
|
-- turn. Snapshotting (rather than refetching per turn) keeps the prompt
|
|
-- prefix byte-stable for KV-cache reuse and keeps the persona's view of the
|
|
-- thread fixed even if SMS-API is re-imported underneath it.
|
|
--
|
|
-- All nullable: an unanchored (open) persona chat leaves them NULL.
