- Configurable backend: claude (CLI) or openai (API), selected in config.yaml
- OpenAI streaming via SSE with conversation history in memory
- Session isolation: config name included in session UUID
- Markdown to Telegram HTML conversion (pulldown-cmark) for final messages
- Fix sendMessageDraft: skip cursor to preserve monotonic text growth,
skip empty content chunks from SSE stream
- Simplify Makefile: single deploy target
Telegram Bot API 9.3+ sendMessageDraft provides smooth streaming text
rendering without the flickering of repeated edits. Falls back to
editMessageText automatically if the API is unavailable (e.g. older
clients or group chats). Also reduces edit interval from 5s to 3s and
uses 1s interval for draft mode.
Async Rust bot (teloxide + tokio) that:
- Authenticates users per chat with a passphrase (resets daily at 5am)
- Generates deterministic UUID v5 session IDs from chat_id + date
- Pipes messages to `claude -p --session-id/--resume <uuid>`
- Persists auth and session state to disk across restarts
- Deploys as systemd --user service via `make deploy`
