 # Social Post Writer Bot — development
 
-Telegram bot that currently echoes text and transcribes voice/audio messages into Russian using APInex Voice STT.
+The bot prepares social media posts on explicit request. It uses APInex STT for Russian voice messages and Gemini 3.8 Flash through APInex for intent classification, post writing/revision, and visual reading of post screenshots to infer a personal Tone of Voice.
 
 - Runtime: Python 3.12, aiogram 3.x
 - Coolify environment: `development` on `spb-easy-dale`
 - Gitea branch: `dev`
-- Runtime secrets are configured only in Coolify environment variables: `BOT_TOKEN`, `BOT_ENV`, `APINEX_API_KEY`.
-- For test bot tokens, set `BOT_ENV=test` to use Telegram's test Bot API.
-- Voice transcription uses raw audio upload to APInex `POST /v1/tools/voice/stt`; voice notes are sent as `audio/ogg`, with Russian language hint.
-- No LLM post writing or automatic social-media publishing yet.
+- Runtime variables are configured only in Coolify: `BOT_TOKEN`, `BOT_ENV`, `APINEX_API_KEY`, `APINEX_STT_MODEL`, `APINEX_INTENT_CLASSIFIER_MODEL`, `APINEX_POST_WRITER_MODEL`, `APINEX_IMAGE_TONE_MODEL`, `BOT_DB_PATH`.
+- Models default to `gemini-3.8-flash`; STT defaults to APInex `nova-2`.
+- Per-user Tone of Voice is stored in SQLite at `/app/data/social_writer.sqlite3`; mount a persistent Coolify volume at `/app/data`.
+- Each explicit post request and each reply-edit returns three posts as separate Telegram messages. No conversational history is stored.
+- Screenshots are sent to vision using inline base64 data URLs; uploaded images and source post texts are not persisted.
