Architecture Overview

Message Flow (Inbound)

Telegram MTProto
    ↓
GramJS NewMessage Event
    ↓
GramJSClient.onMessage()
    ↓
convertToMsgContext() → MsgContext
    ↓
isMessageAllowed() → Security Check
    ↓
Message Queue (per account)
    ↓
pollMessages() → openclaw gateway
    ↓
Agent Session (routed by SessionKey)

Message Flow (Outbound)

Agent Reply
    ↓
channel.sendText()
    ↓
gateway.sendMessage()
    ↓
GramJSClient.sendMessage()
    ↓
Telegram MTProto

Session Routing

• DMs: telegram-gramjs:{accountId}:{senderId} (main session per user)
• Groups: telegram-gramjs:{accountId}:group:{groupId} (isolated per group)

Security Enforcement

Applied before queueing in gateway:

• DM Policy: Check allowFrom list (by user ID or @username)
• Group Policy: Check groupPolicy (open vs allowlist)
• Group-Specific: Check groups[groupId].allowFrom if configured

Key Features

✅ Gateway Adapter

• Implements openclaw ChannelGatewayAdapter interface
• Manages active connections in global Map
• Message queueing for polling pattern
• Graceful shutdown with abort signal

✅ Message Handling

• Converts GramJS events to openclaw MsgContext format
• Preserves reply context and timestamps
• Detects chat types (DM, group, channel)
• Filters empty and channel messages

✅ Security

• DM allowlist enforcement
• Group policy enforcement (open/allowlist)
• Group-specific allowlists
• Pre-queue filtering (efficient)

✅ Outbound Delivery

• Text message sending
• Reply-to support
• Thread/topic support
• Error handling and reporting
• Support for @username and numeric IDs

---

Testing Status

⚠️ Not Yet Tested (Next Steps)

• End-to-end auth flow
• Message receiving and queueing
• Outbound message delivery
• Security policy enforcement
• Multi-account handling
• Error recovery
• Abort/shutdown behavior

---

Known Gaps

Not Implemented (Phase 1 Scope)

• Mention detection - Groups receive all messages (ignores requireMention)
• Rate limiting - Will hit Telegram flood errors
• Advanced reconnection - Relies on GramJS defaults

Not Implemented (Phase 2 Scope)

• Media support (photos, videos, files)
• Stickers and animations
• Voice messages
• Location sharing
• Polls

Not Implemented (Phase 3 Scope)

• Secret chats (E2E encryption)
• Self-destructing messages

Next Steps (For Human Contributor)

1. Install Dependencies

cd ~/openclaw-contrib/extensions/telegram-gramjs
npm install telegram@2.24.15

2. Build TypeScript

cd ~/openclaw-contrib
npm run build
# Check for compilation errors

3. Test Authentication

openclaw setup telegram-gramjs
# Follow interactive prompts
# Get API credentials from: https://my.telegram.org/apps

4. Test Message Flow

# Start gateway daemon
openclaw gateway start

# Send DM from Telegram to authenticated account
# Check logs: openclaw gateway logs

# Verify:
# - Message received and queued
# - Security checks applied
# - Agent responds
# - Reply delivered

5. Test Group Messages

# Add bot account to a Telegram group
# Send message mentioning bot
# Verify group routing (isolated session)

6. Write Documentation

• Setup guide (API credentials, auth flow)
• Configuration reference
• Troubleshooting (common errors)

7. Submit PR

cd ~/openclaw-contrib
git checkout -b feature/telegram-gramjs-phase1
git add src/telegram-gramjs extensions/telegram-gramjs src/config/types.telegram-gramjs.ts
git add src/channels/registry.ts
git commit -m "feat: Add Telegram GramJS user account adapter (Phase 1)

Summary

This session completed the core infrastructure needed for the Telegram GramJS adapter to function:

1. ✅ Gateway adapter - Manages connections, queues messages, handles lifecycle
2. ✅ Message handlers - Convert GramJS events to openclaw format with proper routing
3. ✅ Outbound delivery - Send text messages with reply and thread support

The implementation follows openclaw patterns, integrates with existing security policies, and is ready for integration testing.

What's Next: Install dependencies, test end-to-end, fix bugs, document, and submit PR.
