Build PWA install, visual decklist, and deck profiles for MTG decklist site
Session from merchantscroll-traces on Hugging Face by vedalken · MIT · condensed by Coders Talk
Read the project's feature backlog docs, implement the remaining undeveloped features one at a time with developer review between each, then handle a string of follow-up bugs and polish requests (mobile UX, PWA icons, exports, duplicate deck data) that came up during use.
- +0Prompt · +0Read docs/features/, find undeveloped features, implement the first one, then iterate feature by feature after my review.
- +0mAgent did · +0mRead all feature docs and scanned the codebase for existing PWA pieces; found the PWA (installable webapp) and visual decklist features unstarted, and proposed a PWA implementation plan (manifest, service worker, icons, offline handling).
- +0mAgent did · +0mImplemented the PWA: added manifest.webmanifest, sw.js service worker with app-shell caching, generated icons via a new script, wired install meta tags and offline detection into index.html/player.html, marked feature 7 done in docs.
- +0mIntervention · +0mSaw the install icon was the sponsor logo, not the scroll favicon, and asked for it to use favicon.ico instead; then asked again to center the scroll artwork better in the icon frame.Why: the icon generator was pulling the wrong source image, and once fixed the scroll art was still off-center and small so I had to point that out too
- +0mAgent did · +0mImplemented feature 8 (visual decklist): added a text/visual view toggle, Scryfall image grid rendering, card preview wiring, and persisted the view choice in localStorage.
- +1mIntervention · +1mClarified that 'visual view' should mean the cards are rendered as images, not still showing text lines; the agent had left the visual grid falling back to text/gray boxes.Why: the first pass technically added a toggle but the images weren't reliably loading, so it wasn't actually doing what I asked for
- +1mIntervention · +1mSent a phone screenshot showing the visual grid needed scrolling, the swipe gesture fought with deck navigation, cards were oversized, and the view-toggle button didn't match the Export MTGO button style.Why: the mobile layout was unusable as shipped - too much scrolling, swipe conflicts, and inconsistent buttons all needed fixing together
- +2mPrompt · +2mAdd a decklist profile feature mirroring the player profile: total entries, league entries, trophies (yearly/total), challenge appearances with scores, and top pilot for that archetype.
- +2mAgent did · +2mBuilt src/deck_stats.py to aggregate per-archetype stats and generate profile JSON files, wired it into the pipeline/entrypoint, added the deck profile modal and left/right navigation (metagame vs player), then scanned decks for duplicate archetype names and merged White Weenie/BR Madness/R Madness variants via canonical aliases.
- +3mOutcome · +3mFixed remaining mobile bugs across the session: Android share-cancel not falling back to clipboard/download, visual-mode scroll being blocked by swipe handlers over card tiles, and confirmed PWA/export flows worked in a local Playwright check.
Next time I'd specify up front that 'visual' decklist view means card images replacing the text list entirely, and that mobile touch/scroll behavior needs to work alongside swipe-to-navigate - that ambiguity cost several back-and-forth rounds. The screenshot-plus-DOM-path interventions on mobile layout were what actually got the agent to fix the real problem, versus my vaguer text descriptions which led to partial fixes.
