# 031 — Telegram Media Support + Reset + Typing Keepalive

**Status**: Completed  
**Date**: 2026-02-14  
**Component**: abstractgateway (Telegram bridge)

## Summary

Improve the Telegram bridge so media analysis works in chat, `/reset` is clean, and the typing indicator stays visible while processing.

## Reason

Users can send photos but the agent receives only text JSON; the VLM never sees image pixels. Users also need a reliable `/reset` to start fresh without duplicate listeners, and the typing indicator currently stops too early.

## Scope

### What we do
- Promote Telegram media artifacts to top-level `attachments` in event payloads.
- Use Telegram photo `caption` as message text when present.
- Stash `pending_media` so a follow-up text message can reference the prior image.
- Add `/reset` command to cancel session runs + clear binding, then confirm.
- Keep the typing indicator alive for a configurable duration.

### What we don’t do
- No changes to AbstractCore’s media pipeline (already works).
- No changes to Telegram Bot API limitations (cannot delete user messages in private chats).

## Dependencies
- `abstractgateway` Telegram bridge
- `abstractruntime` LLM_CALL + media handling + durable tool execution

## Expected Outcomes
- VLMs can analyze Telegram images sent to the bot.
- `/reset` cleanly starts a fresh session without duplicate listeners.
- Typing indicator stays visible while the agent processes.

## Report

### Changes Implemented

**Bridge (Bot API + TDLib)**
- Promoted media artifacts into the event payload as `attachments` so VisualFlow context mapping can forward them into `payload.media`.
- Added caption handling so `message.caption` is treated as message text when present.
- Added `pending_media` stash: if a user sends an image with no text, the media is attached to the next text message.
- Added `/reset` command: cancels all runs for the chat session, clears binding, and sends confirmation.
- Added typing indicator keepalive loop (configurable interval + max duration).

### Configuration Notes

New env vars (optional):
- `ABSTRACT_TELEGRAM_TYPING_INTERVAL_S` (default 4.0)
- `ABSTRACT_TELEGRAM_TYPING_MAX_S` (default 600.0)
- `ABSTRACT_TELEGRAM_PENDING_MEDIA_MAX_S` (default 300.0)

### Verification

- Gateway reinstall completed (with version-pin warning only).
- Media pipeline now uses existing AbstractCore VLM support via `generate(media=...)`.

### Limitations

- Telegram Bot API cannot delete user messages in private chats; `/reset` only resets gateway state (binding + runs).

### Files Changed
- `abstractgateway/src/abstractgateway/integrations/telegram_bridge.py`
- `AGENTS.md`
- `abstractflow/web/frontend/src/components/PropertiesPanel.tsx`
