| name | spaced-recall |
| description | Schedule spaced repetition over a memory palace so it lasts, and export to Anki. Use when the user says "spaced repetition", "when should I review", "schedule my reviews", "keep this long-term", "export to Anki", "FSRS", or "SM-2". Computes next-due dates from palace-walk grades, writes the recall block of palace.json, and drives durable retention against the forgetting curve. |
spaced-recall
The durability step. Building encodes; spacing keeps it. Review each locus just before it would
fade — not daily, not never.
When to use this
The user wants a palace to survive weeks and months, asks when to review, or wants their loci in a
spaced-repetition tool (Anki). Pairs with palace-walk, which supplies the grades.
Instructions
-
Pick the scheduler:
- FSRS (Free Spaced Repetition Scheduler) — modern, evidence-led, models per-card stability
and difficulty. Default. Targets a desired retention (e.g. 0.9) and spaces accordingly.
- SM-2 — the classic Anki algorithm; simpler ease-factor model. Use when matching legacy Anki
decks or when the user explicitly wants it.
-
Read the grades. Take per-locus results from palace-walk (got/partial/missed, mapped
to the scheduler's grade scale). A missed is a lapse and shortens the next interval sharply.
-
Compute next-due. Update each locus's recall block: stability, difficulty, reps,
lapses, lastReviewed, and the new due (ISO date). New loci start with a short first
interval; well-recalled loci stretch out.
-
Surface today's queue. When asked "what's due", list only loci whose due ≤ today, in route
order, and hand them to palace-walk. Never front-load the whole palace — spacing is the point.
-
Export to Anki when asked — see references/anki-export.md: one note per locus
(front = station/cue, back = target + image), preserving FSRS/SM-2 state where possible.
-
Respect the no-guilt rule. A skipped review is silent; just recompute from the real
lastReviewed. No streak penalties, no nagging.
Refusals
- Don't schedule reviews more often than the algorithm warrants ("review everything daily" wastes
effort and isn't spacing).
- Don't fabricate
recall state for loci that were never walked — schedule only what's been tested.
