From 8a5e9b214b719b2278c7af0c6261a72f68db54af Mon Sep 17 00:00:00 2001 From: Teknium Date: Wed, 15 Apr 2026 17:17:08 -0700 Subject: [PATCH] feat: automatic Telegram bot creation via Managed Bots (Bot API 9.6) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add client-side support for Telegram's Managed Bots feature, enabling zero-copy-paste bot creation during hermes setup: - New module: hermes_cli/telegram_managed_bot.py - QR code terminal rendering via qrcode library - Deep link generation (t.me/newbot/{manager}/{username}) - Pairing protocol client (nonce registration + token polling) - Full auto-setup orchestrator with animated progress - Setup wizard (hermes_cli/setup.py) - Telegram setup now offers Automatic vs Manual choice - Automatic: scan QR → confirm in Telegram → token saved - Falls back to manual if auto-setup fails or is declined - Dependencies: qrcode>=8.0 (pure Python, no PIL needed) Requires a Nous-hosted manager bot + pairing API (Cloudflare Worker) to complete the flow.
