Telegram Bot Ops

Use this skill when the real question is whether a Telegram bot is receiving updates, processing them in the intended runtime, and sending visible responses to the right chat, user, or forum topic.

Public Safety

• Default to read-only diagnostics.
• Do not print tokens, .env values, connection strings, raw logs, private DMs,

payment payloads, session files, or full user records.

• Use placeholders in notes and examples: <TELEGRAM_BOT_TOKEN>,

<TELEGRAM_USER_ID>, <CHAT_ID>, <TOPIC_ID>, <WEBHOOK_URL>.

• Do not send Telegram messages, restart production services, change webhooks,

edit BotFather settings, or deploy until the user has authorized that exact action.

• If any real secret appears in the repo, logs, or prompt, stop and tell the

user it must be rotated before public release.

Intake

If the repo or runtime is unclear, identify:

• bot repo and language/runtime;
• deployment target: local, Docker, VPS/systemd, Railway, Render, Fly, Vercel, or other;
• update mode: webhook, polling, or unknown;
• env source for TELEGRAM_BOT_TOKEN;
• expected symptom, chat surface, and timestamp;
• whether production restart/deploy is allowed.

Diagnostic Flow

1. Repo and runtime — inspect entrypoints, process manager, deploy files, and

current git state.

1. Environment — verify required env var names exist without printing values.
2. Update intake — classify runtime: HTTP Bot API webhook, HTTP Bot API

polling, MTProto bot session, or MTProto user session.

1. Bot API identity — for Bot API-token runtimes, run getMe using a masked token path.
2. Webhook/polling mode — for Bot API-token runtimes, run getWebhookInfo

and inspect runtime logs.

1. Single update owner — resolve 409 Conflict by reading the error text:

webhook conflict means webhook/deleteWebhook path; competing getUpdates means find the polling owner.

1. Telegram delivery — use a fresh nonce for Bot API or Telethon/user-session

E2E when user-visible behavior matters.

1. Handler/runtime — prove the runtime received and processed the update.
2. Outbound response — prove the bot sent to the expected chat/topic.
3. Incident note — report symptom, evidence, root cause, fix, and residual risk.

Telegram-To-Agent Gateways

When the bot is a gateway from Telegram into an agent runtime, read references/hermes-gateway.md. The reference is Hermes-compatible but intentionally generic: bot handle, host, service name, home directory, chat ids, topic ids, env paths, and logs must be placeholders or redacted.

Bot API vs Telethon / MTProto

• Bot API is Telegram's HTTP interface for bot tokens: getUpdates, webhooks,

sendMessage, getMe, callbacks, payments, and join requests.

• Telethon is an MTProto client. It can be a bot-account runtime with

start(bot_token=...) or a user-session E2E harness for what a Telegram user sees.

• Pick one primary intake per bot token/account: Bot API webhook, Bot API

polling, MTProto bot session, or MTProto user session. Do not mix without a clear deduplication plan.

Webhook And Polling Checks

Safe read-only checks should avoid putting the token-bearing URL in shell history, process listings, or copied logs. Prefer a tiny local helper:

python
import json, os, urllib.request

token = os.environ["TELEGRAM_BOT_TOKEN"]
for method in ("getMe", "getWebhookInfo"):
    with urllib.request.urlopen(f"https://api.telegram.org/bot{token}/{method}") as response:
        data = json.load(response)
    print(method, {"ok": data.get("ok"), "result_keys": sorted((data.get("result") or {}).keys())})

Do not paste the token-bearing URL into notes or issues. In reports, write:

text
getWebhookInfo: webhook_url=<set|empty>, pending_update_count=<n>, last_error=<redacted>

Direct getUpdates diagnostics can consume pending updates. Use it only with a fresh nonce, short timeout, known update owner, and restore plan.

Forum Topics And Privacy

• Non-General forum topics require preserving message_thread_id.
• General topic is normally sent like an ordinary supergroup message: omit

message_thread_id. Preserve message_thread_id for non-General topics.

• With privacy mode enabled, bots see targeted commands, replies to the bot,

inline messages via the bot, service messages, private chats, and channel messages where they are a member. Admin bots can receive all group messages.

• Disabling privacy or removing/re-adding a bot affects group visibility and

requires explicit user authorization.

Restart / Deploy Gate

Before restarting or deploying:

• identify the exact production owner/process;
• capture current status and rollback command;
• state expected downtime or risk;
• confirm the user authorized the action;
• run post-restart getMe, webhook/polling, and one visible smoke test.

Output Format

Answer with:

1. Status — not checked, local only, runtime checked, verified in Telegram, or blocked.
2. Evidence — commands/logs checked, with secrets redacted.
3. Finding — the failing layer or confirmed healthy layer.
4. Action — what changed or the next safe step.
5. Public safety — note if any secret, user data, or private payload was found.

Anti-Patterns

• Claiming "bot works" from unit tests only.
• Printing raw bot tokens, .env, logs, user messages, payment payloads, or DB rows.
• Changing webhook/polling mode without knowing the current production owner.
• Running a local polling process with a production token while production is active.
• Ignoring message_thread_id when the bot lives in Telegram forum topics.
