Message formatting

Greeting templates use a safe Markdown-style format. Raw HTML is shown as plain text, so a custom message cannot inject Telegram markup. Lucy validates templates when you save them with /setwelcome or /setgoodbye.

Text styles

You write	Result
*bold* or **bold**	bold
_italic_	italic
__underline__	underline
~strikethrough~	strikethrough
||spoiler||	spoiler
`code`	inline code
```blocks```	preformatted block
> text	quoted block
[label](https://…)	inline link

Fillings

These placeholders expand when the message sends:

Filling	Meaning
{first}	First name
{last}	Last name
{fullname}	Full name
{username}	@username when present
{mention}	Clickable mention
{id}	Numeric user id
{chatname}	Group title

Unknown placeholders are rejected on save.

URL buttons

Put each button on its own template line:

[Rules](buttonurl://https://example.com/rules)

Append :same to place a button on the same row as the previous one:

[Chat](buttonurl://https://t.me/example:same)

Allowed links

Only these URL schemes are accepted for inline links and buttons:

• http:
• https:
• tg:

Validation

Lucy rejects templates that include invalid placeholders, unsafe links, empty bodies, or text over Telegram’s length limit. Fix the template and run /setwelcome or /setgoodbye again. See also Greetings.
