Spaced Recall

Activation Contract

Use when a learning flow needs long-term retention: scheduling new recall cards, checking which cards are due, or running a review session. Owns review-queue.md under each .ai/learning/<topic-slug>/, following assets/review-queue-template.md.

Do not use for ungraded quizzes — quiz mode reads the same cues but never moves boxes; only review sessions do.

Hard Rules

• There is no scheduler: scheduling is pull-based. The due-check below runs at the start of every /learn invocation, in every mode.
• Never reveal an answer before the learner attempts recall. Retrieval effort is the mechanism, not a formality.
• Grading questions go through native-question-ux, recommended option first.
• Dates are absolute YYYY-MM-DD. Compute Next strictly from the transition table; never invent or backfill review history.
• Card IDs (C-NNNN) are unique per topic and never reused; each card links back to its source Cornell note.
