Telegram Gateway Debug Loop

Use this skill to run end-to-end repros with real Telegram traffic.

Setup

1. Load Telegram credentials from ~/.zeebot/api_keys/telegram.txt.

   • Read the file to get api_id, api_hash, and phone number.
   • NEVER print, echo, or commit these values. Hold them in memory only.

2. Start gateway with debug logging:

   bashCopy

   cd /Users/z80/dev/lemon
   LOG_LEVEL=debug ./bin/lemon-gateway --debug --sname lemon_gateway_debug
   

   Run this in the background and monitor its output.

3. Optionally attach a remote shell for live introspection:

   bashCopy

   iex --sname lemon_attach --cookie lemon_gateway_dev_cookie --remsh lemon_gateway_debug@$(hostname -s)
   

Sending Messages via Telethon

4. Use Telethon through uv (no global install needed):

   bashCopy

   uv run --with telethon python <script.py>
   

   Write a temporary Python script that:

   • Connects with the user's Telegram credentials
   • Sends messages into a dedicated debug topic/thread
   • Keeps all probes in that thread

5. Stress async behavior with prompts that trigger delegation/tool runs:

   • agent_id=coder delegation
   • Async poll loops
   • Multi-step tool workflows

Inspecting Runtime State

6. While traffic is active, inspect runtime state via the remote shell:
   • :sys.get_state(LemonGateway.Scheduler) — scheduler state
   • :sys.get_state(LemonGateway.EngineLock) — lock state
   • DynamicSupervisor.which_children(LemonGateway.ThreadWorkerSupervisor) — active workers

Watching for Failures

7. Watch gateway logs for high-value failure signatures:
   • :unknown_channel — message routed to unknown channel
   • Scheduler stalls or lock starvation
   • Context overflow/trim failures
   • Delivery retries/timeouts

Capturing Repros

8. For each repro, capture:
   • The exact prompt(s) sent
   • Thread ID
   • Timestamps
   • State snapshots from the remote shell
   • Relevant log lines

If $ARGUMENTS is provided, focus the debug session on reproducing that specific issue.

Secrets + Safety

• NEVER print or commit API keys, session strings, OTPs, or phone numbers.
• Keep credentials in local secret files only.
• If session auth is invalid, re-auth locally and update only local secret files.
• Do not include credentials in any script files that get written to disk — pass them via environment variables or read them at runtime.
