Fetch Card Art
Download a card's artwork illustration from the UESP wiki and wire it up in the codebase.
Input
A card name (e.g., "Lurking Crocodile"). Passed as the skill argument.
Workflow
Step 1 — Find the card_id
Search src/deck/card_catalog.gd for a _seed() call containing the card name (the second argument to _seed). Match case-insensitively. Extract the card_id (the first argument).
If the card name is not found in the catalog, report the error and stop.
If multiple cards match (e.g., "Slaughterfish" matches both "Slaughterfish" and "Slaughterfish Spawning"), prefer the exact match. If there is no exact match, list the candidates and ask the user to clarify.
Step 2 — Find the wiki image URL
If the user provided a direct wiki URL (e.g., https://en.uesp.net/wiki/File:LG-cardart-...), fetch that page directly and extract the full-resolution image URL from it. Skip to the thumbnail-to-full conversion step below.
Otherwise, discover the image URL from the card's wiki page:
- Construct the wiki page URL:
https://en.uesp.net/wiki/Legends:<Card_Name> (spaces replaced with underscores)
- WebFetch often returns 403 for UESP due to Cloudflare. Use
curl with a browser User-Agent instead:
curl -sL -A "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36" "<url>" | grep -o 'LG-cardart-[^"]*' | head -5
This extracts all LG-cardart- image references from the HTML. Look for the hash path pattern (e.g., //images.uesp.net/1/13/LG-cardart-Name.png). Card names with special characters like parentheses will be URL-encoded in the HTML. If multiple matches exist (card art + alternate art variants), use the first one — it is the primary card art.
Thumbnail-to-full conversion: If the URL contains /thumb/ and a size prefix like 132px-, convert to the full-resolution URL by:
- Removing
/thumb from the path
- Removing the size-prefixed filename at the end (e.g.,
/132px-LG-cardart-Name.png)
- The result should be:
https://images.uesp.net/<hash_path>/LG-cardart-<Name>.<ext>
Fallback for disambiguation / Beast Form cards: If the card page has no LG-cardart- image (common for Beast Form cards whose wiki pages are disambiguation redirects), try the File: page directly with subtype suffixes:
https://en.uesp.net/wiki/File:LG-cardart-<Card_Name>_(<Subtype>).png (e.g., Circle_Initiate_(Nord).png)- Also try
.jpg if .png returns nothing
- The subtype to use (e.g., "Nord", "Werewolf") can be found in the card's
subtypes field in the catalog _seed() call
Wiki API fallback: If you can't find the full-resolution URL from the card page HTML, confirm the file exists via the wiki API and then fetch the File: page to extract the direct URL:
curl -sL -A "Mozilla/5.0" "https://en.uesp.net/w/api.php?action=query&titles=File:LG-cardart-<Card_Name>.png&format=json"
If the response contains a pageid (no "missing" key), the file exists. Then fetch the File: page and extract the direct image URL from the href pointing to //images.uesp.net/<hash>/<hash>/LG-cardart-<Name>.png.
If none of these attempts find card art, report the error and stop.
Step 3 — Download and save the image
- Sandbox workaround: The sandbox blocks direct
curl writes to assets/. Download to $TMPDIR first, then copy:
curl -sL -A "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36" "<url>" -o "$TMPDIR/<card_id>.png"
- Verify the downloaded file is actually a PNG (not an HTML error page) using
file. If it's HTML, the download was blocked — report the error.
- If the image is not PNG, convert it to PNG using
sips -s format png (macOS)
- Copy to final location:
cp "$TMPDIR/<card_id>.png" assets/images/cards/<card_id>.png
Step 4 — Verify
Confirm the file was saved successfully by checking it exists and has a non-zero size.
Report success with the card name, card_id, and file path.
Notes
- The
art_path field is automatically set by _build_card() in card_catalog.gd using the convention res://assets/images/cards/<card_id>.png, so no catalog changes are needed per card.
CardDisplayComponent._resolve_art_texture() will automatically pick up the new image on next load.- If the image already exists at the target path, overwrite it with the fresh download.
- Dual-form / transform cards (e.g., Beast Form creatures): The base form uses the seeded
card_id for its art path. Transform targets are inline card_templates with a definition_id — card_relationship_resolver.gd resolves their art to res://assets/images/cards/<definition_id>.png. To fetch art for both forms, download each separately using the appropriate ID. The wiki typically has separate pages for each form with disambiguators in parentheses, e.g., Legends:Grim_Shield-Brother_(Nord) and Legends:Grim_Shield-Brother_(Werewolf).
