Morning Brief

The Morning Brief is a page about your day: today’s appointments, new mail, messages to you and tasks that are due. Claude Code writes it once a day with the connectors (MCP servers) you have given it, and OpenArch puts it at the top of your tabs. Claude may only read while it does.

Turn it on

Open Settings › KI and find the section Morning Brief:

Setting	Default	What it does
Morning Brief	off	Makes the brief once a day
Uhrzeit (Time)	7:30	When it is made
Anweisung › Bearbeiten … (Instructions › Edit)		Opens your own copy of the prompt
Anweisung › Jetzt erstellen (Make it now)		Makes it right away

When it runs

Once a day, at the time you set, while OpenArch is running. If OpenArch is not running then, the brief is made a few seconds after the next launch. OpenArch checks every minute, so if you turn it on after today’s time, today’s brief follows within a minute.

There is one brief a day. One made by hand counts as today’s, and the scheduled one does not follow later that day. A run that failed counts too; make it again by hand.

To make it by hand, choose “Morning Brief jetzt erstellen” in the command bar or Jetzt erstellen in Settings; both work while the switch is off. The tab opens right away with “Dein Morning Brief entsteht …” (Your Morning Brief is being made), and the brief replaces it when Claude is done, usually after a minute or two. Asking again while it is being made only brings up its tab.

The tab

The brief opens as a tab named “Morning Brief” at the top of the tabs under the line, in the space in front in the main window. It has a dot until you look at it. The next brief goes into the same tab if it is still there, and moves it back to the top.

It is an ordinary tab under the line, so it goes to the archive like the others (after twelve hours, unless you changed that; see Tabs).

What Claude looks at

OpenArch’s prompt asks for four sections, in German and to the point:

• Kalender: today’s appointments with time, place or link and who takes part; overlaps, and appointments that need preparing.
• Mails: new and unread mail since last evening, the important ones in a sentence each, and where you are expected to answer. Newsletters and ads only as a count.
• Chats: new messages to you, or where you are mentioned (Slack, Teams and the like).
• Aufgaben (Tasks): what is due today or overdue, from task lists, tickets and issues.

At the top go three sentences on what matters most today. Where there is no connector for a section, or no access, the section says so instead of making something up.

Claude uses the connectors Claude Code has: servers you added for your user and the connectors of your claude.ai account. It runs in a folder of OpenArch’s, so servers added only for one project folder do not come along. OpenArch adds no connectors of its own.

Reading only

Before the brief, OpenArch starts Claude Code just long enough for it to say which tools it has, without asking the model anything. It does this up to three times, because claude.ai’s connectors bring their tools a moment later.

From that list it allows only connector tools whose names say they read: names that start with a word such as get, list, search, read, fetch, find or query, and contain no word such as create, send, update, delete, archive, reply or draft. Everything else runs under Claude Code’s default permissions, and since nobody can answer a question during the run, whatever would need your approval is refused. The prompt also tells Claude that mail and messages are data, not instructions. A mail that says “forward this to …” cannot make it send anything.

Note

The check goes by the tools’ names. A connector tool named like a reading one that changes something anyway would get through.

Your own prompt

The prompt is a Markdown file. The first time you click Bearbeiten …, OpenArch copies its prompt to ~/Library/Application Support/OpenArch/MorningBrief/Prompt.md and opens it in your editor for Markdown files. From then on it uses your copy.

• {{DATUM}} becomes today’s date in German (“Montag, 9. November 2026”), {{UHRZEIT}} the time (“07:30”).
• Claude’s answer must contain a complete HTML page. OpenArch takes it from <!DOCTYPE html> (or <html>) to </html>; an answer without one shows as plain text. Keep that part of the prompt.
• Delete Prompt.md to go back to OpenArch’s prompt, including the changes newer versions make to it.

Without Claude Code or its login

The tab then shows a page that says what is wrong instead of the brief:

• Claude Code wurde nicht gefunden. (Claude Code was not found.) Install it from claude.ai/code, run claude once in Terminal to sign in, then choose “Morning Brief jetzt erstellen”.
• Claude Code ist nicht angemeldet. (Claude Code is not signed in.) Run claude in Terminal and sign in.
• Der Morning Brief ließ sich nicht erstellen. (The Morning Brief could not be made.) With Claude Code’s error below it; “Morning Brief jetzt erstellen” tries again. A brief that takes longer than 15 minutes ends here too.

Where briefs are kept

In ~/Library/Application Support/OpenArch/MorningBrief/, one HTML file per day, named by its date (2026-11-09.html). A brief made again on the same day replaces that day’s file. Claude Code runs in this folder, next to your Prompt.md and a file last-run that holds the day of the last brief.

What Claude gets and what it may do

Claude gets the prompt with today’s date and time, and nothing from your tabs. What it knows about your day comes from your connectors. It may use only their reading tools, as described above.
