Telegram Telethon

Codex Behavior Guidelines

Draft vs Send: Follow User's Intent

Key Rules

1. Explicit draft → draft: "драфт", "draft" → use draft command immediately
2. Explicit send → send: "отправь", "пошли", "send" → use send command immediately
3. Ambiguous → clarify: If neither "draft" nor "send" verb present, ask: "Создать драфт или сразу отправить?"

Examples

User: "сделай драфт для lv: привет" Codex: Uses draft --chat "lv" --text "привет" immediately

User: "отправь сообщение Маше: встретимся в 5?" Codex: Uses send --chat "Маша" --text "встретимся в 5?" immediately

User: "напиши сообщение для Маши: встретимся в 5?" Codex: Asks "Создать драфт или сразу отправить?"

Scripts import from src/telegram_telethon. Install the package in editable mode so tg.py/tgd.py can resolve imports:

cd telegram-telethon
pip install -e .
# or with dev tools (pytest, coverage):
pip install -e ".[dev]"

Relationship to telegram Skill

The separate telegram skill (single-script telegram_fetch.py backed by telegram_dl) overlaps on list/recent/search/send/edit/download/thread but differs:

With the publish/markdown/schedule ports now complete, telegram-telethon is a superset of telegram on everything except the external telegram_dl auth dependency. Use this skill for:

• publish — draft→channel workflow (frontmatter, media albums, post-publish move + index update, post-flight lint)
• --markdown on send / publish — markdown→Telegram HTML conversion
• --schedule on send / publish — ISO / relative / natural-language scheduled delivery
• Daemon mode + Codex spawning, voice transcription (Telegram/Groq/Whisper), delete / forward / mark-read, local draft / drafts / draft-send, lint-channel, non-interactive auth setup.

Prerequisites

Interactive Setup (Terminal)

Run setup wizard on first use:

python3 scripts/tg.py setup

This guides through:

1. Getting API credentials from https://my.telegram.org/auth
2. Phone number verification
3. 2FA (if enabled)
4. Optional daemon trigger configuration

Non-Interactive Setup (Codex)

For use from Codex or scripts without TTY:

# Step 1: Provide credentials and trigger code send
python3 scripts/tg.py setup --api-id 12345678 --api-hash abc123... --phone +1234567890

# Step 2: User receives code on phone, then complete auth
python3 scripts/tg.py setup --api-id 12345678 --api-hash abc123... --phone +1234567890 --code 12345

# If 2FA enabled, add password
python3 scripts/tg.py setup --api-id 12345678 --api-hash abc123... --phone +1234567890 --code 12345 --password mypassword

The script auto-detects TTY and switches between interactive/non-interactive modes.

CLI Commands

Message Operations

# List all chats
python3 scripts/tg.py list [--limit 30] [--search "term"]

# Fetch recent messages
python3 scripts/tg.py recent [CHAT] [--limit 50] [--days 7] [--format markdown|json] [--output file.md]

# Search messages by content
python3 scripts/tg.py search QUERY [--chat "Chat Name"] [--limit 50] [--format markdown|json]

# Fetch unread messages
python3 scripts/tg.py unread [--chat "Chat Name"] [--format markdown|json]

# Fetch forum thread
python3 scripts/tg.py thread CHAT_ID THREAD_ID [--limit 100]

# Send message
python3 scripts/tg.py send --chat "Chat Name" --text "Message text" [--reply-to MSG_ID] [--file path] [--topic TOPIC_ID] [--markdown] [--html] [--schedule "+1h" | "tomorrow 10:00" | "2026-04-10T09:30"]

# Edit message
python3 scripts/tg.py edit --chat "Chat Name" --message-id MESSAGE_ID --text "New text"

# Delete messages
python3 scripts/tg.py delete --chat "Chat Name" --message-ids 123 456 789 [--no-revoke]

# Forward messages
python3 scripts/tg.py forward --from "Source" --to "Dest" --message-ids 123 456

# Mark messages as read
python3 scripts/tg.py mark-read --chat "Chat Name" [--max-id MSG_ID]

Draft Operations

# Save/update a draft message
python3 scripts/tg.py draft --chat "Chat Name" --text "Draft text" [--reply-to MSG_ID] [--no-preview]

# Clear a draft (save empty text)
python3 scripts/tg.py draft --chat "Chat Name" --text ""

# Clear all drafts
python3 scripts/tg.py draft --clear-all

# List all drafts
python3 scripts/tg.py drafts [--limit 50]

# Send a draft as a message (clears the draft)
python3 scripts/tg.py draft-send --chat "Chat Name"

Note: Use "me" as the chat name to target Saved Messages (your own chat). The literal name "Saved Messages" doesn't work as it's localized differently per user.

Media Operations

# Download media from chat
python3 scripts/tg.py download "Chat Name" [--limit 5] [--output-dir ~/Downloads] [--message-id ID] [--type voice|video|photo]

# Transcribe a single voice message (MESSAGE_ID required)
python3 scripts/tg.py transcribe "Chat Name" MESSAGE_ID [--method telegram|groq|whisper]

# Batch-transcribe recent voice messages (omit MESSAGE_ID, use --batch)
python3 scripts/tg.py transcribe "Chat Name" --batch [--limit 10] [--method telegram|groq|whisper]

Publish a Draft to a Channel

End-to-end publish workflow: parse a draft markdown file, resolve the destination channel from folder structure or frontmatter channel:, upload media (single file or album), post-process to move the draft to published/ and insert an entry in the channel index.

# Dry-run preview
python3 scripts/tg.py publish --draft "Channels/klodkot/drafts/20260416-post.md" --dry-run

# Publish now
python3 scripts/tg.py publish --draft "20260416-post"  # slug works too

# Publish scheduled for later
python3 scripts/tg.py publish --draft "..." --schedule "tomorrow 10:00"

The result JSON includes published, channel, message_id, media_count, moved_to, and — crucially — lint_warnings when the final body contains leaked markdown/HTML that Telegram wouldn't render. Post-publish bookkeeping failures (e.g. index write error) surface as warnings but don't roll back the send.

Markdown Formatting on Send

Pass --markdown to convert a markdown-flavored message into Telegram HTML before sending:

python3 scripts/tg.py send --chat "@mychannel" --markdown \
  --text $'## Release\n\n**v2** ships _today_. See [docs](https://example.com).\n\n* fast\n* stable'

Rules (applied in order): ## Header → bold line; * item / - item at line start → → item; **bold** → <b>; _italic_ → <i>; [text](url) → <a href>. Pre-existing HTML passes through unchanged, so the flag is safe to add to content that was already authored as HTML.

Pair with lint-channel below to catch cases where --markdown was forgotten.

Sending Pre-written HTML

Pass --html to send text that already contains Telegram-compatible HTML tags (<b>, <i>, <a href>, <code>, <pre>, <u>, <s>, <tg-spoiler>, <blockquote>):

python3 scripts/tg.py send --chat "@mychannel" --html \
  --text '<b>Release v2</b> ships today. See <a href="https://example.com">docs</a>.'

Unlike --markdown (which converts markdown syntax to HTML), --html sends the text as-is with parse_mode='html'. Use --html when you have already authored HTML content or when programmatically building messages with tags.

Scheduled Delivery

Pass --schedule with one of three formats (naive times default to Europe/Berlin):

# Relative: send in one hour
python3 scripts/tg.py send --chat "@mychannel" --text "..." --schedule "+1h"

# Natural: send tomorrow morning
python3 scripts/tg.py send --chat "@mychannel" --text "..." --schedule "tomorrow 09:30"

# Absolute: send at a specific time
python3 scripts/tg.py send --chat "@mychannel" --text "..." --schedule "2026-04-20T15:00"

The response includes "scheduled_for": "<iso datetime>" when the message is queued for later. Telegram displays scheduled messages in the chat's scheduled-messages view.

Lint Published Messages

Scan a channel (or a single message) for unrendered markdown/HTML that leaked into the raw message text — i.e. the sender forgot --markdown or the HTML conversion failed, so readers see literal **bold**, <b>…</b>, [text](url), or ## Header in the post.

# Scan last 50 messages in @mychannel
python3 scripts/tg.py lint-channel --chat "@mychannel"

# Scan last 200 messages
python3 scripts/tg.py lint-channel --chat "@mychannel" --limit 200

# Lint a single message by ID
python3 scripts/tg.py lint-channel --chat "@mychannel" --message-id 1234

# Machine-readable output for pipelines / CI
python3 scripts/tg.py lint-channel --chat "@mychannel" --json

The detector lives in modules/lint.py as a pure function (detect_unrendered_markup(text, entities)), so it can also be called directly on drafts or wired into a post-flight check after publishing. Content inside MessageEntityCode/MessageEntityPre spans is ignored (inline code / code blocks are expected to contain raw characters).

Obsidian Integration

--to-daily and --to-person are flags on the read commands (recent, search, unread), not standalone subcommands:

# Append recent messages to today's daily note (Daily/YYYYMMDD.md in the active vault)
python3 scripts/tg.py recent "Chat Name" --to-daily

# Append search results to today's daily note
python3 scripts/tg.py search "query" --to-daily

# Append recent messages to a person's note
python3 scripts/tg.py recent "Chat Name" --to-person "Person Name"

The target vault path is resolved by the formatting helpers in utils/formatting.py; there are currently no --vault or --section overrides on the CLI.

Voice Transcription

The skill supports three transcription methods with automatic fallback:

1. Telegram API (default) - Uses Telegram Premium's server-side transcription
2. Groq - Uses Groq's Whisper API (requires GROQ_API_KEY environment variable)
3. Whisper - Uses local OpenAI Whisper model (requires pip install openai-whisper)

# Use Telegram's transcription (Premium feature)
python3 scripts/tg.py transcribe "Chat" 123

# Force Groq transcription
python3 scripts/tg.py transcribe "Chat" 123 --method groq

# Force local Whisper
python3 scripts/tg.py transcribe "Chat" 123 --method whisper

Daemon Mode

The daemon monitors Telegram for messages matching configured triggers and can:

• Reply with static text
• Spawn Codex sessions to handle requests
• Resume existing Codex sessions per-chat
• Queue requests to prevent rate limiting

Trigger Configuration

Triggers are stored in ~/.config/telegram-telethon/daemon.yaml:

triggers:
  # Respond to /Codex command in DMs
  - chat: "@myusername"
    pattern: "^/Codex (.+)$"
    action: Codex
    reply_mode: inline

  # Respond to @Bot mentions in a group
  - chat: "AI Assistants"
    pattern: "@Bot (.+)$"
    action: Codex
    reply_mode: new

  # Simple ping-pong in any chat
  - chat: "*"
    pattern: "^/ping$"
    action: reply
    reply_text: "pong"

Codex:
  allowed_tools:
    - Read
    - Edit
    - Bash
    - WebFetch
  max_turns: 10
  timeout: 300

queue:
  max_concurrent: 1
  timeout: 600

Trigger Fields

Codex Integration

When action is Codex:

1. Text captured by regex group 1 is sent to Codex via Codex -p "..." --output-format json
2. Codex sessions persist per-chat in sessions.json
3. Subsequent messages from same chat resume session via --resume <session_id>
4. Responses are sent back to Telegram as reply or new message

Session Persistence

Codex sessions are saved to ~/.config/telegram-telethon/sessions.json:

• Each chat_id maps to a Codex session_id
• Sessions survive daemon restarts
• Track message count and last used timestamp

To reset: delete chat entry from sessions.json or configure a /reset trigger.

Example Configurations

Personal AI Assistant

Respond to all DMs to yourself:

triggers:
  - chat: "@yourusername"
    pattern: "(.+)"
    action: Codex
    reply_mode: inline

Group Bot with Mention Trigger

Only respond when @mentioned:

triggers:
  - chat: "Dev Team"
    pattern: "@AssistantBot (.+)"
    action: Codex
    reply_mode: inline

Multi-Action Setup

triggers:
  - chat: "*"
    pattern: "^/ask (.+)"
    action: Codex
    reply_mode: inline

  - chat: "*"
    pattern: "^/ping$"
    action: reply
    reply_text: "pong"

  - chat: "Noisy Group"
    pattern: ".*"
    action: ignore

Example User Requests

Mapping natural-language asks to commands:

Saved Messages: Use "me" (not "Saved Messages") — the label is localized per user.
