by sanyuan0704 · 3K installs
The skill
Book Study is a reading coach that guides you chapter by chapter: pre-reading questions, knowledge compilation into a wiki, Socratic mastery tests and spaced-repetition review.
Only when you ask.

How the habit works.
You don't have to.
When does it start? How does it check its work? What does it remember?
One run, step by step.
Then it stops.
Stops after one chapter cycle or review session per run.

Ingest

Spaced repetition: due items are reviewed first on every return, with intervals that stretch on a pass and reset on a fail.
