Anki add-on: Step 2 Shelf Retention Dashboard

Step 2 Shelf Retention Dashboard is a free, read-only Anki add-on for AnKing Step 2 users. It ranks your Step 2 Shelf/rotation subjects from weakest to strongest using Anki-style retention and progress metrics. Main features: Home-screen snapshot with weakest and strongest shelf subjects Full dashboard under Tools > Step 2 Shelf Retention Dashboard Subject/shelf rankings Subtopic breakdowns Sortable columns Retention, Total Cards, Active Cards, % Unsuspended, % Reviewed, % Mature, Leeches, Fails, and Passes Diagnostics / Tag Detection CSV export It is designed for Step 2/Shelf tags such as: #AK_Step2_v12::!Shelf Retention logic: Again = fail. Hard, Good, and Easy = pass. Mature cards use Anki’s standard interval >=21 days definition. Safety: This add-on is read-only. It does not change cards, notes, tags, decks, scheduling, FSRS settings, due dates, intervals, suspensions, or deck options. How to use: Install the add-on. Restart Anki. Open the Decks screen to see the compact snapshot. Go to Tools > Step 2 Shelf Retention Dashboard for the full dashboard. Click Diagnostics / Tag Detection if tags are not detected. Click Refresh to recalculate. Double-click a subject to view subtopics. Click column headers to re-rank by different metrics. Compatibility: Built/tested on Anki 25.09.4. Designed around AnKing Step 2 v12 Shelf tags, especially: #AK_Step2_v12::!Shelf Limitations: This is a tag-level approximation of Anki’s True Retention Table because Anki does not expose a stable public tag-level true-retention API. It is intended as a study-planning dashboard, not as an official Anki statistics replacement.
