GOAL

Document two new features (installable PWA and a visual card-image decklist view) in the project's docs/features/ folder, then get help starting the local dev server and debugging why the first-load page shows the wrong tournament date.

  1. Prompt · +0
    Add to docs/features/ a feature to create a webapp that can be downloaded to smartphone, so instead of the browser it shows as an app
  2. Agent did · +0m
    Reviewed existing feature-doc format and frontend setup, then wrote docs/features/installable-webapp.md (PWA manifest, icons, service worker) and added it to the features README index
  3. Prompt · +0m
    Add a feature to visualize the decklist as a visual view, rendering card images instead of card names
  4. Agent did · +0m
    Investigated current decklist rendering and Scryfall image usage, then wrote docs/features/visual-decklist.md (grid view, view toggle, lazy loading) and updated the features README
  5. Prompt · +0m
    How to start localhost on Cursor?
  6. Agent did · +0m
    Checked scripts/start_server.py and terminal history, explained how to run 'uv run scripts/start_server.py' and open localhost:8000 in Cursor's Simple Browser
  7. Prompt · +0m
    Bugfix: on first visit the site shows an arbitrary page/date instead of the most recent decklist (showing Jun 16 when today is the 17th)
  8. Agent did · +0m
    Traced how the initial tournament/deck index is chosen on load, reading index.html, index.json, info.json and utils.py, and checking start times of raw tournament data to find why the wrong date loads first
  9. Outcome · +0m
    Session ended mid-investigation: two feature docs (PWA install, visual decklist) were written and added to docs/features/README.md, localhost startup was explained, but the first-load date bug was still being diagnosed with no fix applied yet
VERDICT

I'd start by pointing the agent straight at the load/init logic (index.html's tournament selection and index.json sorting) instead of letting it explore the whole file top to bottom, since that's where the actual bug lived. The doc-writing tasks went smoothly because I gave clear feature descriptions upfront and let it match the existing docs/features format. Next time I'd also mention the expected 'most recent' sort behavior explicitly so it can jump to the starttime comparison faster.
