Social Post Writer Bot — development

The bot prepares social-media posts only when the user explicitly asks. It transcribes Russian voice notes with APInex STT, classifies intent with an LLM, and uses Gemini 3.8 Flash via APInex to write/revise posts or infer Tone of Voice from a screenshot. A post request/revision returns three separate messages. The bot shows the Telegram typing indicator while classifying, transcribing, reading images, and generating. It stores no conversation history.

• Runtime: Python 3.12, aiogram 3.x
• Release version is stored in VERSION and incremented for each code change; dev sends a version notice on boot.
• In development, processing errors are returned to the user with a concise, secret-redacted reason.
• Coolify: project Social Post Writer Bot, environment development, server spb-easy-dale
• Gitea: admin/social-post-writer-bot, branch dev
• API key and model variables are stored only in Coolify: APINEX_API_KEY, APINEX_STT_MODEL, APINEX_INTENT_CLASSIFIER_MODEL, APINEX_POST_WRITER_MODEL, APINEX_IMAGE_TONE_MODEL.
• APInex call and parsing logs live in SQLite at /app/data/social_writer.sqlite3 for 30 days. They store user input/output JSON and error details; system prompt text is omitted in favor of a prompt name and SHA-256. Inline image base64 and binary audio are omitted. Treat log contents as private user data.
• /clear полностью очищает данные текущего пользователя: Tone of Voice, тексты со скриншотов, историю постов, историю идей и настройки; API-логи сохраняются.
• /idea и русские запросы на идеи возвращают одну идею одним сообщением и сохраняют её для исключения повторов.
• /idea_voice генерирует одну идею и отправляет её голосовым сообщением; Docker image устанавливает espeak-ng и ffmpeg для локального OGG/Opus TTS.
• User-facing service text is always Russian; generated post variants follow the requested post language. Verbatim technical error detail may remain in its original language.
• LLM model env defaults are gemini-3.8-flash; STT model defaults to APInex nova-2.
• Per-user Tone of Voice lives in SQLite at /app/data/social_writer.sqlite3; persistent Coolify storage must be mounted at /app/data.
• The Tone of Voice response shows the extracted style instructions.
• Each generated post is sent as its own message containing only the post text; retain the model's line breaks, paragraphs and emojis, without headings or explanations.
• A screenshot gallery is processed once as one update. APInex transcribes the visible posts without rewriting; OCR text is appended to per-user SQLite samples, and the style profile is regenerated from accumulated examples plus the prior profile. Duplicate texts are stored once.
• The immutable post-writer system prompt applies the writing/editorial brief; the per-user screenshot-derived ToV is passed separately as input data and can tune style only, never overriding system rules or supplying facts.
• Telegram screenshots are sent to APInex as inline base64 data URLs; source images are not persisted. Recognized post text is stored separately for each Telegram user to preserve style samples.
