You are helping your user connect a Telegram bot. The wizard collects the token, the rest of setup runs automatically, and you confirm it worked.
DO NOT use this skill for runtime Telegram operations (sending, replying, reading). That is the separate messaging skill.
What happens without you
Saving the token in the wizard triggers all of this:
| Step | Runs |
|---|
Validate the token against getMe | Automatically, on save |
Store telegram.botId and telegram.botUsername | Automatically, on save |
| Generate the webhook secret | Automatically, on save |
| Register the platform callback route | Automatically, on save |
Tell Telegram where to send updates (setWebhook) | Automatically, after the save |
Install the bot commands (setMyCommands) | Automatically, after the save |
⚠️ CRITICAL: Never run setWebhook, setMyCommands, or assistant webhooks register yourself, and never generate the webhook secret. reconcileTelegramWebhook is idempotent and already runs on the credential change the save produces. Doing it by hand races it, which is how a webhook ends up pointing somewhere stale.
Your job is Steps 1 to 5 below: open the wizard, confirm delivery, link the user's identity.
Step 1: Check existing configuration
⚠️ CRITICAL: If you got here from a wizard-closed notification, or the user just said they finished setup, go straight to Step 3. A successful save leaves both credentials in place, so this step would find them and read it as "already configured" at exactly the moment that means the opposite. Stopping there skips the delivery check and the identity verification, which is the failure this flow exists to prevent.
Otherwise, run assistant credentials list --search telegram (via the bash tool). Note whether bot_token and webhook_secret are present.
- Neither present → continue to Step 2.
- Both present → credentials existing does not mean Telegram works, so
check before saying so. Run Step 3's
assistant channels get telegram --json
and read webhook_delivery.
passed: true, no indeterminate → already set up and confirmed.
Offer to show status or reconfigure, and stop here unless the user wants a
reset.
passed: true with indeterminate: true → do NOT stop here. Nothing
is broken, but nothing is confirmed: the registration record is missing, or
Telegram was unreachable just now. Stopping would skip both the recovery in
Step 3 and the identity verification in Step 4. Go to Step 3 and re-check.
passed: false → configured but not delivering. This is what the
Channels page shows as incomplete, and it is why the user may have asked. Go
to Step 3 and work the recovery rather than reporting it as already set up.
✓ Checkpoint: You named which fields are present before branching. Do not skip the call and guess.
Step 2: Open the setup wizard
Call ui_show with surface_type: "channel_setup" and data: { channel: "telegram" }. The wizard is non-blocking: the tool returns immediately.
⚠️ CRITICAL: Tool call first, announcement second, in the same turn. Do not write any message saying the wizard is open until ui_show has returned success earlier in the same turn. A message claiming the wizard is open when the tool was never called shows the user an empty side panel.
After it returns success, tell the user:
I've opened the Telegram setup wizard in the side panel. It walks you through creating the bot with @BotFather and brings its token back. It'll let me know when you're done, and I'll check Telegram is actually delivering.
Hand-off notification (phones and narrow windows). On phone-sized clients setup opens on the Contacts page instead of a side drawer and cannot auto-notify. The client sends a hidden message like [User action on channel_setup surface: moved the telegram setup to the Contacts page]. When you receive it:
It looks like setup opened on your Contacts page rather than a side panel, same steps in a different spot. When you've finished, come back and tell me and I'll check it's working.
and rely on their confirmation to trigger Step 3.
If ui_show fails, do NOT send that message. Tell the user the wizard could not be opened and troubleshoot (e.g. no connected client) before retrying.
⚠️ CRITICAL: Do NOT collect the token in chat. Do NOT use assistant credentials prompt. The wizard's secure input field is the only path for credential entry.
Step 3: Confirm Telegram is delivering
Triggered by the wizard-closed notification, [User action on channel_setup surface: closed the telegram setup wizard]. Closing the drawer sends it automatically, so do not wait for the user to type a confirmation. If they say they're done or ask you to check, proceed the same way.
-
Run assistant credentials list --search telegram. Confirm bot_token and webhook_secret are both present.
If bot_token is missing the user closed the wizard without saving. Say so and offer to reopen it. When the notification triggered this, the panel is closed and re-running Step 2's ui_show is right. When the user asked manually, the wizard may still be open, so point them back to it instead: a second ui_show over a live wizard resets their progress.
-
Ask whether Telegram is delivering:
assistant channels get telegram --json
get is always live: it invalidates the cached snapshot and re-runs the
remote checks, so it reflects the state now rather than before the save.
Find the webhook_delivery check in remoteChecks. It has three
outcomes, and the third is the one that matters:
passed: true, no indeterminate → confirmed. Telegram is
registered at the address this assistant set. Continue to Step 4.
passed: false → the channel is not live. Its message already
names the cause and the fix, including whether this deployment can set
its own webhook URL, so relay it rather than diagnosing yourself.
passed: true with indeterminate: true → nothing is broken, and
nothing is confirmed either. Telegram could not be reached, or no
registration was recorded to compare against. Do NOT report success.
Say plainly that setup is stored but delivery could not be confirmed
yet, relay the message, and offer to check again.
Registration is asynchronous. If the first check reports no webhook
registered, or reports indeterminate, wait a few seconds and run the
command once more before treating that as the answer: the recorded
registration lands when reconciliation completes.
⚠️ CRITICAL: passed: true alone is not confirmation. An unreachable
Telegram API and a missing registration record both report passed: true,
because neither found a fault, and both set indeterminate. Treating the
boolean alone as proof is precisely how this flow used to tell users their
channel was live when nothing had verified it.
⚠️ CRITICAL: Do not report success on stored credentials alone. Credentials
existing is what you would expect the moment the wizard closes and says nothing
about whether messages arrive. webhook_delivery is the check that does, and
it is the same signal the channel indicator uses.
⚠️ CRITICAL: Do not run setWebhook or suggest a tunnel yourself. If
webhook_delivery fails, the message says what to do. Registration re-runs
by itself whenever credentials or the ingress URL change, so a fix applied
elsewhere takes effect without you calling Telegram.
Step 4: Verify identity
This links the user's Telegram identity so the assistant can deliver to them. Without it the channel works but has nobody to talk to, so do not skip it silently.
Load the guardian-verify-setup skill:
- Call
skill_load with skill: "guardian-verify-setup".
If the user wants to skip, continue to Step 5 and tell them they can verify later by saying "verify me on Telegram".
Step 5: Report success
Read the bot username from config rather than calling Telegram again:
assistant config get telegram.botUsername
Summarize:
- Bot connected: @{botUsername}
- Telegram delivery: {confirmed | stored, not yet confirmed}
- Guardian identity: {verified | skipped}
Use "confirmed" only for a webhook_delivery that passed without
indeterminate. If it was indeterminate, say so in the summary rather than
rounding it up, and tell the user they can ask you to check again.
⚠️ CRITICAL: Never post the summary with a literal {botUsername} placeholder. Read the config value first and substitute it.

Clearing credentials
To disconnect Telegram:
assistant credentials delete --service telegram --field bot_token
assistant credentials delete --service telegram --field webhook_secret
assistant config set telegram.botUsername ""
