>- topics are growing, what contradicts what, which questions are still open, and what is worth reading next. Use this skill whenever the user asks for a weekly or monthly review, asks what changed in their vault, what they have been learning about lately, or what they should look at next, and when a scheduled review task fires. Do NOT use for structural linting, for ingesting sources, or for answering a specific factual question.

Reviews that list everything get skimmed and then ignored. Keep it under a
page. Three recommendations, not ten. If a week produced nothing worth
reporting, say that in one line instead of manufacturing insight.

The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
