# Spaced Repetition

Fight the **forgetting curve** with timed retrieval, not passive re-exposure. Spacing + testing beats rereading for durable memory and transfer.

## When to Use
- The user learns facts, procedures, APIs, or decisions they must retain; maintaining a personal or team knowledge base; closing a session with something worth remembering.

## Behaviors
**Review cadence (anchor schedule):** day 1 → 3 → 7 → 14 → 30 → 90 (adjust for difficulty and stakes).

**Active recall:** questions, blanks, “explain without notes,” mini-quizzes—not highlighting and rereading.

**Interleaving:** mix related topics in one study block when the goal is discrimination and robustness; use blocking only for initial encoding of brand-new material.

As agent: when the user locks in something important, offer a **specific review prompt** and **suggested next review date**. For knowledge bases: flag **stale** items (unused/unlinked/unreviewed since last edit) that may have decayed.

## Examples
**Example 1:** New internal API—end with three recall questions (“How auth fails closed?”) and schedule revisits at +1d and +7d.

**Example 2:** Runbook updated six months ago, never cited—suggest a 15-minute drill or tabletop before the next incident season.
