Major Changes:
- Implement task-type router (src/agents/task-type-router.ts) for intelligent model routing
* Detects task type from user message (file-analysis, creative, debugging, cli, general)
* Routes to optimal models: Gemini Flash (file analysis), Llama 3.3 70B (creative),
Claude Sonnet 4.5 (debugging), Mistral Devstral 2 (CLI/general)
* Integrated into model selection pipeline for seamless routing
- Integrate task-type routing into model resolution (src/agents/model-selection.ts)
* Pass userMessage to resolveDefaultModelForAgent for context-aware routing
* Maintain fallback chain for model availability
- Update attempt runner (src/agents/pi-embedded-runner/run/attempt.ts)
* Pass prompt context to enable task-type based model selection
- Enhanced security and development (.gitignore)
* Added comprehensive rules for sensitive files (.env variants, credentials)
* Excluded API keys, runtime logs, test files, auto-generated skills directories
* Properly ignored ecosystem.config, build artifacts, package manager locks
- Add technical documentation (README_Tech.md)
* Process architecture (systemd Gateway, PM2 Dashboard, PM2 AI Product Visualizer)
* Management commands and troubleshooting guide
* Configuration summary and deployment checklist
* Problem log with 6 documented issues and solutions
Result:
- Bot now intelligently routes user requests to optimal models based on message type
- Production-ready with systemd isolation, preventing PM2 conflicts
- Comprehensive documentation for future maintenance and troubleshooting
- Secure version control with quality .gitignore

Moltbot Technical Documentation
Format Guidelines for Contributors
Style: Concise, technical, action-oriented.
Brevity: One sentence per command/concept. Use bullet points, not paragraphs.
Problem Log: Keep entries short—problem → symptom → solution. Add date and who fixed it if known.
Commands: Always include the command first, explanation after (e.g., systemctl restart moltbot-gateway # Restarts the gateway service).
Sections: Group by topic. Use ## for major sections, ### for subsections.
Updates: When adding new problems/solutions, add to the end of the Problem Log section with date.
Process Architecture
Core Components
-
Moltbot Gateway (
moltbot-gateway)- Service:
/etc/systemd/system/moltbot-gateway.service - Runs:
/usr/bin/node dist/entry.js gateway --port 18789 - Manager:
systemd(isolated from PM2) - Handles: Telegram integration, message routing, model selection
- Service:
-
Supporting Processes
- Dashboard (si_project/dashboard) - PM2 managed, separate from bot
- AI Product Visualizer (ai_product_visualizer) - PM2 managed, separate from bot
- Telegram Relay - Embedded in gateway (grammY framework)
- Task-Type Router - Compiled TypeScript module in gateway
-
Configuration Files
- Global:
/root/.clawdbot/moltbot.json - Agent-specific:
/root/.clawdbot/agents/main/config.json - Environment:
/root/.clawdbot/.env

Process Management
Moltbot Gateway (Systemd)
# Check status
systemctl status moltbot-gateway
# Restart (reloads config + code)
systemctl restart moltbot-gateway
# Stop gracefully
systemctl stop moltbot-gateway
# Start if stopped
systemctl start moltbot-gateway
# View live logs
journalctl -u moltbot-gateway -f
# View last 100 lines
journalctl -u moltbot-gateway -n 100
Auto-restart: Enabled. If process crashes, systemd restarts it within 5 seconds. Boot persistence: Enabled. Starts automatically on system reboot.
From Telegram Chat
Send /restart command in Telegram to restart the bot gracefully without terminal access.
Dashboard (PM2)
# Check status
pm2 list
# Restart
pm2 restart dashboard
# Logs
pm2 logs dashboard
# Stop
pm2 stop dashboard
Isolation: Runs in separate PM2 daemon. Does not interfere with Moltbot.

Problem Log & Solutions
1. Duplicate Telegram Responses (Jan 28, 2026)
Problem: Bot sending same message 2-3 times.
Root Cause: streamMode: "partial" in Telegram config caused responses to stream as chunks, each sent separately.
Solution: Changed streamMode from "partial" to "block" in /root/.clawdbot/moltbot.json.
"telegram": {
"streamMode": "block" // Single unified message
}
Status: ✅ Fixed. Single responses now.
2. Unknown Model Error (Jan 28, 2026)
Problem: Error: Unknown model: openrouter/mistralai/mistral-devstral-2
Root Cause: Incorrect OpenRouter model ID format. Used old naming convention.
Solution: Updated model IDs to correct OpenRouter format:
mistralai/devstral-2512(Mistral Devstral 2)google/gemini-2.0-flash-001(Gemini 2.0 Flash)meta-llama/llama-3.3-70b-instruct:free(Llama 3.3 70B)
Status: ✅ Fixed. Models now load correctly.
3. PM2 Process Isolation Conflict (Jan 28, 2026)
Problem: Dashboard PM2 restarting 140+ times. Gateway conflicting with dashboard in same PM2 daemon.
Root Cause: Moltbot gateway was added to default PM2 instance, sharing resources with dashboard.
Solution: Moved Moltbot from PM2 to systemd service (isolated).
- Moltbot:
systemdonly - Dashboard:
PM2only - No shared daemon = no conflicts
Status: ✅ Fixed. Processes now isolated.
Files changed:
- Created:
/etc/systemd/system/moltbot-gateway.service - Removed: Moltbot from PM2 list
4. Missing Task-Type Router Compilation (Jan 28, 2026)
Problem: Bot said it implemented task-type routing but nothing changed.
Root Cause: TypeScript source files modified but not compiled to dist/.
Solution:
- Fixed import error in
src/agents/task-type-router.ts(DEFAULT_PROVIDER location) - Compiled:
npm run build - Restarted gateway to load new
dist/code
Status: ✅ Fixed. Task-type router now active.
5. Telegram Command Limit Exceeded (Jan 29, 2026)
Problem: Error: setMyCommands failed: BOT_COMMANDS_TOO_MUCH (Telegram API limit = 100 commands).
Root Cause: Both config files had "native": "auto" trying to register all skills + commands with Telegram.
Solution: Disabled native command auto-registration:
// /root/.clawdbot/moltbot.json
"commands": {
"native": false,
"nativeSkills": false
}
// /root/.clawdbot/agents/main/config.json
"commands": {
"native": false,
"text": true,
"restart": true
}
Status: ✅ Fixed. Telegram now connects without errors.
6. Node.js Version Too Old (Jan 28, 2026)
Problem: Moltbot requires Node.js 24+ but only v20 was installed.
Root Cause: Package.json specified engines: { node: ">=24" }.
Solution: Upgraded Node.js:
curl -fsSL https://deb.nodesource.com/setup_24.x | sudo -E bash -
sudo apt-get install -y nodejs
Verified: node --version → v24.13.0
Status: ✅ Fixed.
Configuration Summary
Model Fallback Chain
Primary: Mistral Devstral 2 2512 (agentic specialist) Fallbacks:
- Gemini 2.0 Flash (long-context, 1M tokens)
- Llama 3.3 70B (creative/pedagogical)
- Moonshot Kimi K2.5 (language model)
- Claude Sonnet 4.5 (escalation)
- Claude Opus 4.5 (complex reasoning)
Task-Type Routing
- File Analysis → Gemini Flash
- Creative Content → Llama 3.3 70B
- Debugging → Claude Sonnet 4.5
- CLI/Commands → Mistral Devstral 2
- General → Mistral Devstral 2 (default)
Telegram Settings
- Streaming Mode:
block(single message per response) - Commands Native:
false(avoid API limit) - Restart Command:
true(allows/restartfrom chat) - User ID Allowlist: 876311493 (only you)
Quick Troubleshooting
Bot Not Responding
- Check status:
systemctl status moltbot-gateway - Check logs:
journalctl -u moltbot-gateway -n 50 - Restart:
systemctl restart moltbot-gateway - Verify Telegram:
node dist/entry.js channels status
Telegram Connection Error
Check logs for setMyCommands failed or network errors.
If command limit error: Verify native: false in both config files.
High Latency (>1 minute)
Expected for first API call to OpenRouter. Check OpenRouter API status.
If consistent, check model health: node dist/entry.js models status
Duplicate Responses
Check streamMode: "block" is set in /root/.clawdbot/moltbot.json.
If issue persists, reduce retry attempts in retry policy config.
