 **Knowledge** (formerly Sources) is what the assistant searches: uploads, links, and content synced from your connections. The **Add knowledge** and **Add Tool** dialogs, the composer's Knowledge and Tools menus, and the agent builder all start the same flow, and list tools grouped by the connection they use. A service offered two ways appears as one card: Confluence syncs pages into Knowledge and, through **Jira & Confluence**, lets agents search and update Jira and Confluence. GitHub does both from one connection: see [GitHub](#github).
 
-A connector's page is the one place to manage it: its accounts (**Reconnect**, **Disconnect**), the Knowledge it syncs (**Sync now**), and its tools (on or off, and what each action may do). On the Knowledge and Tools pages, anything from a connection has **Manage connection** in its menu, which opens that page. Disconnecting keeps synced content but stops its sync.

+### Several accounts of one service
+
+You can connect the same service more than once, for example two Telegram bots. Give each account a name when you connect it (**Name this account**) or later with **Rename**. When you have more than one account of a service, its tools are listed as "Telegram · Alerts bot", and the assistant sees each account's actions under that account's name, so it can pick the right one.
+
+### Fixed values
+
+Under **Customize**, each action lists its parameters. A parameter is either left to the AI (**Let AI decide**) or set to **Always use** a value. A fixed value is sent on every call; the AI never sees it and can't change it, even when a prompt asks it to. Only the tool's owner can change fixed values.
+
+A Telegram connection can hold a **Default chat ID**. When it's set, messages always go to that chat. To find a chat's id, add the bot to the chat, send it a message, and open `https://api.telegram.org/bot<token>/getUpdates`. The same bot with another default chat is a separate connection. When team members use their own accounts, each member's messages go to their own default chat.
