-- Read out a short recap of the user's recent activity. Pulls from four
-- independent sources, picks the freshest, and stitches them into a one-shot
-- TTS reply. Works fully offline — no LLM call.

-- Sources:
--   1. Last assistant reply (jarvis.llm_last_reply)
--   2. 3 most recent memory facts (sorted by last_used_at desc)
--   3. Active scheduled tasks (jarvis.scheduler.list)
--   4. Active profile (just to colour the tone)

-- 3) Last assistant reply (if any)
local last = jarvis.llm_last_reply()
if last and last ~= "" then
    -- Trim to ~100 chars to keep the recap snappy
    local snippet = last:gsub("%s+", " "):sub(1, 120)
