List Pokémon TCG singles on the ekcope-46 eBay store via lake-of-rage ebay-sell (Trading AddFixedPriceItem). Groups photo dumps, IDs cards from catalog not vision, prices from gold + TCGPlayer + live asks, posts GTC listings with buyer-paid USPS First Class letter. Use when listing, drafting, revising, or bulk-uploading Pokémon cards on eBay; when the user gives a photo folder/zip; when they mention ebay-sell, Seller Hub, Magical Bulk, item specifics, or shipping policy. Do not post until the user confirms the preview. Not for buy-side Browse scrape or gold.sales ingest (pipeline skill).

The file

We split this skill into the rules it gives an agent

4 rules. About 0 are common, 2 are distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Call a card Reverse Holo unless the user confirms the photo is reverse.

    line 24
  2. Distinctive:

    Use free shipping or eBay Standard Envelope as the default.

    line 25
  3. Very specific:

    Use Inventory createOffer as the happy path — this seller’s live listings are Trading.

    line 26
  4. Very specific:

    Post: only the cards they name: resize ≤1600px, ebay-sell post-draft --drafts … --index N --photos ….

    line 38

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

eBay listing (Pokémon singles)

Store: ekcope-46. Code: lake-of-rage/pipelines/ebay_scraper/src/ebay_scraper/sell/. Run CLI on lake-vps-lor-main (tokens in ~/.config/ebay/, 0600). Never print tokens, auth codes, or street address.

Canonical policy IDs, category, and CCG descriptors live in ebay_scraper.sell.config and ebay_scraper.sell.listing — do not fork them here.

Do not

  • Post without a confirmed preview (title, condition, price, photos, shipping).
  • Trust Nemotron / vision for set, number, rarity, finish, or grade.
  • Call a card Reverse Holo unless the user confirms the photo is reverse.
  • Use free shipping or eBay Standard Envelope as the default.
  • Use Inventory createOffer as the happy path — this seller’s live listings are Trading. Inventory is empty until migrated.
  • Print secrets or the ship-from street. Postal comes from merchant location PRIMARY.

Workflow

Detail: references/process.md.

  1. Group photos by ~30s timestamp gaps. Inside a card: several fronts, then backs/corners. Not strict front/back pairs.
  2. Identify from the card face + catalog.json (tcg_card_id, number, rarity). neo3-5 is Delibird, not Shuckle (neo3-51).
  3. Condition is the user’s call. Propose from photos, then wait. CCG ungraded = condition ID 4000 + descriptor 40001.
  4. Price from gold rollup / TCGPlayer solds / PriceCharting / live eBay asks. Do not invent BINs.
  5. Draft titles/SKUs/specifics via listing.py (build_title, build_sku, store_description). Preview HTML before post.
  6. Post only the cards they name: resize ≤1600px, ebay-sell post-draft --drafts … --index N --photos …. Default shipping policy is buyer-paid USPS First Class letter (~$1.40), Ground/parcel backup. Duration GTC.
  7. Verify ebay-sell listings + GetItemShipping (letter ~$1.40). Direct URL is live immediately; search can lag a few minutes.

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
