Markus

A Claude Code plugin that turns Claude into your personal assistant. It knows you, remembers your context across sessions, and acts autonomously on your behalf.

Getting started

Requires Bun and a Claude.ai account (not API key).

/plugin marketplace add swen128/markus
/plugin install markus@markus
claude --agent markus:personal-assistant --dangerously-load-development-channels plugin:markus@markus

On first session, Markus introduces itself and asks about you — your name, preferences, how you like to work. Everything it learns carries over to the next session.

Markus works best when paired with a messaging channel so it can reach you outside the terminal. Install the Telegram or Discord plugin and launch with both:

claude --agent markus:personal-assistant --channels plugin:telegram@claude-plugins-official \
       --dangerously-load-development-channels plugin:markus@markus

What you can do

It remembers you. Share something once — your timezone, your coding style, a project decision — and Markus writes it down. Next session, it already knows.

You: My timezone is Asia/Tokyo and I prefer tabs over spaces.
     (Markus updates your profile and remembers for next time)

--- next session ---

You: What's my timezone?
     → Asia/Tokyo

It reflects on what happened. Ask it to periodically review the conversation and save anything worth remembering — decisions, preferences, context.

You: Every 30 minutes, reflect on what we've been doing and save anything important.
     (Markus schedules a cron task and reflects autonomously.)

It acts on a schedule. Cron tasks fire as channel notifications between your messages, so Markus can act without you prompting it.

You: Every morning at 9am, check my deployment status and summarize it.
     (Markus schedules the task and runs it autonomously.)

It has personality. Markus maintains a SOUL.md that defines how it behaves — tone, style, values. You can shape it over time.

You: From now on, always respond in bullet points.
     (Markus updates SOUL.md. Next session, it still uses bullet points.)
