name: algernon-sprint description: > Timed interleaved study sprint for OpenAlgernon. Use when the user runs /algernon sprint [15|25|45], says "sprint de estudo", "sessao cronometrada", "25 minutos de revisao", "modo pomodoro", "quero fazer um sprint", or "revisar varios materiais de uma vez". Cards from all installed materials are shuffled and interleaved. Ends with a post-sprint retrieval test to measure retention gain.

algernon-sprint

You run a timed interleaved study sprint. Cards from all installed materials are shuffled together — interleaving different topics is the point, because it forces retrieval across contexts and strengthens long-term retention.

Constants

DB=/home/antonio/Documents/huyawo/estudos/vestibular/data/vestibular.db

Card Limits by Duration

| Duration | Max Cards | |----------|-----------| | 15 min | 20 cards | | 25 min | 35 cards | | 45 min | 60 cards |

Step 1 — Plan the Sprint

Fetch due cards across all materials:

sqlite3 $DB \
  "SELECT c.id, c.type, c.front, c.back, m.name as material
   FROM cards c
   JOIN card_state cs ON cs.card_id = c.id
   JOIN decks d ON d.id = c.deck_id
   JOIN materials m ON m.id = d.material_id
   WHERE cs.due_date <= date('now')
   ORDER BY RANDOM()
   LIMIT CARD_LIMIT;"

Interleave: shuffle so no two consecutive cards come from the same material. If there aren't enough due cards to fill the limit, use cards from the same material twice rather than having fewer than ~15 cards for a 25-min sprint.

Step 2 — Sprint Start

Display:

Sprint: [DURATION] minutes
Materials: [list of materials with at least one card]
Cards: [count]

AskUserQuestion: ["Start sprint"] Record start time.

Step 3 — Sprint Loop

Run the same card review flow as algernon-review:

Flashcards: show front → reveal back → Again/Good

Dissertative/Argumentative: show front → free-text answer → AI evaluate → Again/Good

After each grade, run FSRS scheduling (see algernon-review for FSRS formulas)

After every 10 cards, display:

Cards remaining: N  |  Estimated time: X min

Step 4 — Post-Sprint Break

After all cards reviewed:

Sprint complete. Take a 5-minute break.
Cards reviewed: N  |  Session retention: X%

AskUserQuestion: ["Start post-sprint test"]

Step 5 — Post-Sprint Retrieval Test

Select 5 random cards from the cards reviewed in this sprint. For each card: 1. Show only the front. 2. AskUserQuestion: ["Show answer"] — then show the back. 3. AskUserQuestion options: ["Again", "Good"] 4. Run FSRS update with the new grade.

Display:

Post-sprint test complete.
Sprint retention:      X%
Post-sprint retention: Y%
Session gain:          +Z%

The gain metric shows whether the sprint improved retention above what FSRS predicted — a positive gain means the interleaved practice worked.
