Rebuild Merchant Scroll's frontend and crawl pipeline for Pauper decklists
Session from merchantscroll-traces on Hugging Face by vedalken · MIT · condensed by Coders Talk
Turn a rough scope-of-work doc into a working spec, then implement the described MTGO Pauper decklist browser: a TikTok-style scrolling frontend, a Scryfall-based color enrichment pipeline, and interactive navigation.
- +0Prompt · +0Read docs/sow.md, act as expert PM/webmaster, ask me questions, then iteratively update the SOW as we discuss it.
- +0mAgent did · +0mRead the whole codebase, asked three rounds of structured clarifying questions about navigation UX, color computation rules, and section scope, then drafted a full rewritten SOW.
- +0mPrompt · +0mStart building.
- +0mAgent did · +0mBuilt the Scryfall color enrichment pipeline, reworked index.html/style.css for breadcrumb navigation, color pips and tournament badges, then built a proper crawl.py orchestration script with dedup, enrichment and index rebuild.
- +2mFail · +2mColor pips stopped showing again after a merge; traced it to 5 tournament files re-crawled by GitHub Actions without color enrichment, overwriting the enriched data.
- +2mAgent did · +2mMade the mobile decklist compact (2-column layout), added challenge win/loss records with rank-based sorting, fixed a deck-count bug that showed loaded count instead of the site total.
- +3mIntervention · +3mPlayer search was buggy (dropped queries while loading, stale results); developer said it's out of scope for now and told the agent to remove it entirely instead of fixing it.Why: the search was broken and not important right now, better to cut it than keep patching it
- +4mPrompt · +4mGo ahead and implement the proposed UI redesign (dark theme, compact header, slide transitions) but skip the 4-of card highlight for now.
- +4mAgent did · +4mImplemented dark theme via CSS variables, compact header, directional slide transitions, larger color pips, a progress indicator, and a light/dark toggle with localStorage persistence.
- +5mOutcome · +5mSession ended with a working dark/light themed frontend, 648 enriched tournament files, challenge results sorted by rank, and docs/new_features.md tracking deferred ideas (card highlighting, deck archetype classification).
I'd start the next session by pasting in the actual SOW questions up front instead of doing three rounds of back-and-forth, since most of the ambiguity was around color computation rules and navigation UX that I could have specified from the start. Cutting the buggy player search instead of trying to patch it was the right call and saved time. The recurring color-enrichment-lost-on-recrawl bug showed I need to bake enrichment into the pipeline itself rather than as a separate manual step, which we eventually did.
