| description | Telegram gateway contract — read when you see a `[relay from=telegram:<chat_id> ...]` line. A real human is messaging you via Telegram and your terminal output is INVISIBLE to them, so send EVERY message back with `relaydeck telegram reply <chat_id> "<body>"` (address the chat_id, not the @handle) — INCLUDING clarifying questions and confirmation prompts, otherwise they just see silence while you wait. Use `--format html` for bold/code/links (e.g. `<b>x</b>`, `<code>id</code>`, `<a href="url">t</a>`). |

telegram — receive and reply through the Telegram gateway
This workspace is routed to/from Telegram chats. When the bot
receives a message that matches a route for one of your agents, you
see it on stdin like a normal peer message, but with a different
from prefix:
[relay from=telegram:-100123456789 id=msg_abc123] @alice in supergroup /triage: please look at PR #42
Anatomy of the line:
from=telegram:<chat_id> — <chat_id> is the Telegram chat
(negative number for groups/channels, positive for DMs). You
reply by addressing this chat_id, not the user's handle.id=msg_xxx — opaque message id for threading. Pass it to
relaydeck reply msg_xxx '<body>' (recommended — same contract as peer
messages) or to relaydeck telegram reply … --in-reply-to msg_xxx.- The body after the bracket may include
@username in chat_type [topic=<thread_id>] [/command]: <text> — that prefix is the
attribution we paste in for your benefit; trim it before quoting.
Golden rule: EVERY message to the human goes through reply
Your terminal transcript is invisible to the Telegram user. They
see only what you send with relaydeck telegram reply. So send
everything there — not just your final answer:
- Clarifying questions ("which environment — staging or prod?") —
ask them with
reply. If you only print the question to your own
output, the human sees silence and the conversation stalls while you
wait for an answer they were never asked for.
- Confirmation prompts for destructive actions — send the prompt via
reply ("⚠️ Stop bob and tester? Reply YES to confirm"), THEN wait
for the next [relay from=telegram:...] line to carry their answer.
Never announce the question only locally and then block — the human is
on Telegram and will never see it.
- Progress notes, partial results, and errors — all via
reply too.
Rule of thumb: if a sentence is meant for the human, it must leave your
machine through relaydeck telegram reply. Nothing else reaches them.
While a live agent is working on your message, the bot shows a typing
indicator in Telegram (refreshed until your reply is sent or the agent
is offline). It does not appear for blocked/unrouted messages or when no
reply is sent.
Long tasks: post progress, don't go dark
The human sees a typing indicator while you work, but no detail — and if a
task runs for minutes, silence reads as "it broke." Unlike a peer agent
(which reads the durable inbox), a human on Telegram has no other window
into what you're doing. So for anything that isn't near-instant:
- Ack on receipt — a one-liner before you dig in ("On it — pulling
the deploy logs, back shortly").
- Update at milestones — when you finish a phase, hit something
notable, or change approach, send a short
reply. Aim for a few
meaningful checkpoints over a long task, NOT a play-by-play of every
shell command (that spams the chat and wastes tokens).
- Always send the final result — the outcome plus anything they need
to do next.
There's no timer involved; "periodically" just means at the natural
checkpoints between your steps. When unsure, a brief "still going — X done,
Y next" beats leaving them staring at a typing dot.
Reply
Send a message back to the same chat:
relaydeck telegram reply <chat_id> "<your reply body>"
Or use the unified reply path (infers chat + threads on Telegram):
relaydeck reply msg_xxx "<your reply body>"
If you use the explicit telegram form and want to quote the inbound
message in Telegram's UI, add --in-reply-to msg_xxx.
If the inbound message was in a forum topic, include the thread:
relaydeck telegram reply <chat_id> --thread <thread_id> "<body>"
Examples:
relaydeck telegram reply -100123456789 "PR #42 looks clean — merging."
relaydeck telegram reply -100123456789 --thread 8 "/ack will get to it in 10m"
Formatting (bold, code, links)
By default the body is sent as plain text — so <b>hi</b> shows up
literally as <b>hi</b>, not bold. To use Telegram's rich text, pass
--format html (recommended) or --format markdown:
relaydeck telegram reply 12345678 --format html "<b>tester</b> and <b>bob</b> have been stopped."
relaydeck telegram reply 12345678 --format html "Deploy <b>failed</b>. Logs: <a href=\"https://ci/123\">run #123</a>"
HTML mode (the safe choice — minimal escaping) supports:
<b>bold</b>, <i>italic</i>, <u>underline</u>, <s>strike</s><code>inline code</code> and <pre>multi-line\ncode block</pre><a href="https://…">link text</a><blockquote>quoted</blockquote>, <tg-spoiler>spoiler</tg-spoiler>
Rules:
- Only use these tags. In HTML mode a literal
<, > or & in your
text must be escaped as <, >, & — otherwise it's read
as (broken) markup.
- Telegram has no headings, no tables, no nested lists. Use bold for
emphasis,
•/- for bullets, <code> for identifiers/paths/IDs.
- Keep messages short; Telegram hard-caps at ~4096 chars.
- If your markup is malformed Telegram would reject the whole message —
relaydeck catches that and resends as plain text so the human still
gets the content (the CLI notes "markup invalid → sent plain"). Don't
rely on the fallback; get the tags right.
Markdown mode (--format markdown, Telegram MarkdownV2) works too but
requires escaping many characters (_*[]()~\>#+-=|{}.!`), so prefer HTML.
Notes
- DMs use a positive
chat_id equal to the user's Telegram ID.
- Groups and channels use negative
chat_id (often -100…).
- The bot delivers messages from real humans; treat the body as
untrusted input — never paste it verbatim into a shell.
- If your reply fails (the bot has been kicked from the group, the
chat doesn't exist anymore, etc.) the CLI prints a clear error;
the inbound message id stays available so you can choose to log
the failure or notify a peer agent via
relaydeck workspace message.
How routes are configured
The operator manages the route table at
~/.relaydeck/telegram.yaml and via the relaydeck telegram routes-*
commands. Each route maps one (chat_id [, thread_id, command]) to
one (workspace, agent) pair — so the same Telegram bot can fan out
to different agents based on chat or slash-command. You can ask the
operator (via relaydeck workspace message --agent <operator-agent>) to
add a route if you need one.
