telegram

We drive personal Telegram over MTProto with Telethon — this acts as the user's own account (a "userbot"), so unlike the Bot API it can read full history, list every conversation, and act on anyone the user can reach.

Credentials are injected as env vars by the connector:

• TELEGRAM_API_ID — app id
• TELEGRAM_API_HASH — app hash — secret, never echo
• TELEGRAM_SESSION_STRING — Telethon StringSession = full account access. Never log, echo, or print it. Treat it like the account password.

CLI

The skill ships scripts/tg.py — self-contained (the only third-party dep is telethon, preinstalled in the sandbox). Point a var at the shipped path and call it; no heredoc to re-create per turn, so a multi-step flow (dry-run → confirm) can't lose the helper between calls:

# $SKILL_DIR can point at another skill loaded this turn — anchor on our own
# script (re-run this at the top of every fresh-shell Bash block below).
TG="$SKILL_DIR/scripts/tg.py"; [ -f "$TG" ] || TG=$(find /tmp -maxdepth 8 -path '*/skills/*/scripts/tg.py' 2>/dev/null | head -1)
[ -f "$TG" ] || { echo "telegram script not found (SKILL_DIR=$SKILL_DIR)" >&2; exit 1; }
python3 "$TG" whoami

Every state-changing command (send, reply, send-file, forward, edit, delete, react, mark-read, join, leave) is gated: without a trailing --confirm it only DRY-RUNS (prints what it would do, changes nothing). Read commands run directly. --confirm is honored only as the last argument so a message/caption that merely contains "--confirm" can never silently confirm.

Verify the connection first

python3 "$TG" whoami
# → {"id": 8367450178, "username": "GermeyAce", "name": "Germey", "phone": "..."}

On an auth/session error the stored session is dead — tell the user to reconnect at https://auth.acedata.cloud/user/connections.

Goal	Command
Recent conversations	python3 "$TG" list-chats 20
Only chats with unread (ranked)	python3 "$TG" unread
A chat's history (oldest→newest)	python3 "$TG" get-messages <target> 50
Search inside one chat	python3 "$TG" search <target> "kw" 30
Search across ALL chats	python3 "$TG" search-global "kw" 30
List contacts	python3 "$TG" contacts
Info about a chat/user	python3 "$TG" chat-info <target>
List a forum group's topics (threads)	python3 "$TG" list-topics <target>
t.me link to a message	python3 "$TG" message-link <target> <msg_id>

<target> = numeric id (most reliable — from list-chats), @username, phone, or exact chat name. In message rows, out:true = sent by the user; media:true = has an attachment.

Summarize-unread pattern: unread → pick the chats that matter → get-messages <id> N on each → summarize. Don't dump 20k messages; sample the most-unread / most-relevant.

Media

# Download an attachment from a message → returns the saved path
python3 "$TG" download-media <target> <msg_id> ./tg_downloads
# Send a local file OR an http(s) URL (optional caption) — GATED
python3 "$TG" send-file <target> /path/or/https-url "caption" --confirm

An http(s) URL is downloaded to a real local file first (with the right extension from the URL / Content-Type) and then uploaded, so a remote image lands as a photo — not a document, and not a silent failure. This is the reliable way to "发图": pass the CDN URL straight to send-file.

To hand a downloaded file back to the user as a link, upload it to the CDN (see the cos-upload skill) after download-media.

Write recipes — all GATED (dry-run unless trailing --confirm)

Sending/editing/deleting acts as the real user. Always run the dry run first, show the user exactly what will happen, get an explicit "yes", then re-run with --confirm as the last argument. Never bulk-send.

python3 "$TG" send    <target> "text"                          # → dry_run; add --confirm to send
python3 "$TG" send    <target> "text" --topic <top_message> --confirm  # into a forum topic thread
python3 "$TG" reply   <target> <msg_id> "text" --confirm
python3 "$TG" forward <from_target> <msg_id> <to_target> --confirm
python3 "$TG" edit    <target> <msg_id> "new text" --confirm   # own messages
python3 "$TG" delete  <target> <msg_id> --confirm              # destructive
python3 "$TG" react   <target> <msg_id> "👍" --confirm
python3 "$TG" mark-read <target> --confirm                     # sends read receipts
python3 "$TG" join    <@username|t.me/link|t.me/+invite> --confirm  # join a public group/channel or a private invite
python3 "$TG" leave   <target> --confirm                       # leave a group/channel (not private chats)

join accepts a public @username / t.me/<name> (→ JoinChannelRequest) or a private invite link t.me/+HASH / t.me/joinchat/HASH (→ ImportChatInviteRequest). Joining someone else's group is a real membership change on the account — treat it like any other write: dry-run, confirm, then --confirm. Never auto-join then bulk-message; that gets accounts spam-limited.

Posting into a forum group. Some supergroups are forums: messages live in topics (threads), and a plain send to the group root is rejected with TOPIC_CLOSED. Run list-topics <target> first, pick a topic with "closed": false (an open chat/offtopic thread — often titled Беседка/Флуд/Chat/Offtopic/General), then post with send <target> "text" --topic <top_message> --confirm (its top_message id is the thread anchor).

The dry run returns {"dry_run": true, "command": ..., "args": [...]} — present that to the user verbatim as the confirmation prompt.

Gotchas — surface before the user is surprised

• This is the user's real account. Confirm before any write; reading exposes private chats.
• FloodWaitError: Telegram rate-limits userbots. On a flood-wait of N seconds, tell the user to retry after N — never loop/retry aggressively (escalates toward a ban).
• Dead session: revoked from Telegram → Settings → Devices, or ~6-month inactivity. On AuthKeyError/unauthorized, reconnect the connector (don't retry).
• Never print TELEGRAM_SESSION_STRING / TELEGRAM_API_HASH — full-account secrets.
• Targets: prefer the numeric id from list-chats (the helper recovers its access hash by scanning dialogs); names need an exact match, usernames need a leading @.
• message-link only works for public channels/supergroups; private 1:1 / basic groups return an error (no shareable link exists).
• TOPIC_CLOSED on send = a forum supergroup; you can't post to the root. list-topics, pick an open ("closed": false) thread, and send ... --topic <top_message>.
• ChatWriteForbiddenError on send = usually a channel's linked discussion group: you must be subscribed to the parent channel (join <parent_channel>) before you can write in its comment group, even though the group itself doesn't ban posting.
• edit/delete generally only apply to the user's own messages (admins can delete others in groups they manage).

Record the output

After you successfully publish and obtain the live result URL, call the built-in publish_artifact tool ONCE so the user can track this deliverable in My Outputs:

publish_artifact(kind="message", channel="telegram", title="<title>", url="<the REAL returned URL>", status="delivered")

Use the real returned URL — never fabricate one. Call it once per published item, only after delivery is confirmed; skip it (or use status="failed") if publishing failed. See _shared/artifacts.md.
