Demo · Cursor (or any MCP agent) + Cosmos
Would not schedule that. Left a why.
Learning that matches the heading
An agent calls Cosmos before it invents a study plan. Busywork that fights the deadline gets refused.
New here?
Cosmos is the product of Polarity Lab. Your agents check with it before they send, book, or draft. If something should wait, it says so and leaves a why. One account across the lab. The whole of you stays with you.
Alex is studying for a professional certification with a deadline in a few months.
Proves
Stops busywork plans. Teaches what matches the deadline.
01 · Alex declares a heading
In Cosmos, Alex sets a path: pass the certification by spring.
Alex opens Cursor with Cosmos connected. The agent calls Cosmos before proposing a plan.
02 · Refuse what fights the bar
A generic agent would dump a twelve-topic syllabus into the thread.
Cosmos returns refuse: three modules fight the deadline. Left a why. One review item is due today.
03 · Teach from the signature
Alex asks for help on the current module.
The agent searches the curated graph: last week's wrong answer, Alex's preference for mechanism-first explanations, a real example from work.
The reply references those nodes instead of starting from zero.
04 · A miss becomes durable
Alex confuses two steps. The agent captures the correction linked to the module.
Cosmos schedules review on Alex's forget curve. The miss does not disappear in chat scrollback.
05 · Without Cosmos
Same model and a detailed system prompt with the syllabus in the thread.
The one-session answer can be good.
Next week there is no refuse bar, no link to the misconception, and the next chat starts cold.
Closing
The difference is not a smarter single reply. It is a judgment call before the plan lands, then a trajectory that remembers what to teach.
Terms (optional)
- Check
- The agent asks Cosmos before it acts. You can check the same way from today or text.

- What still needs you. The thing that cleared the bar.
- Quiet
- Most of life never interrupts you. You see the count. That is the product.
- Would not
- Cosmos returns would not send (or would not book, would not draft), with a why.
