Discover Linter

prototype

Paste your metadata before you publish. The linter applies Epic's Discover rules and hands you a list of fixes, not an opaque score.

Genre decides, tags do not

Epic states it explicitly: the genre, one per island, decides your eligibility for Discover rows. Tags change nothing there, they only feed search.

Most creators do the opposite: they pile on tags and pick a genre at random. That is the first thing this linter checks.

Discover score

0 / 100

How this score is computed

Base+100
Missing title-22
No genre selected-22
Missing description-22
Thumbnail compliance not confirmed-22
Update cadence too low-10
No tags-4

Every rule broken removes a fixed number of points by severity: 22 for a blocking issue, 10 for a warning, 4 for a remark. No hidden model, no secret weighting.

Missing title
blocking
The title field is empty.
With no title, the island is indexed by no search and the Discover tile shows an empty space.
Fix: Write a 3 to 6 word title that says what the player is going to do.
No genre selected
blocking
No genre selected.
Genre is the only field that decides your island's eligibility for Discover rows. An island with no genre enters no row, whatever the rest of its metadata says.
Fix: Pick the single genre that best describes the gameplay loop, not the one that looks busiest.
Missing description
blocking
The description field is empty.
The description feeds Epic's keyword search and its semantic search. Empty, it deprives the island of half its discovery surface.
Fix: Write two to four sentences: the gameplay loop, the player count, what makes the island different.
Thumbnail compliance not confirmed
blocking
Thumbnail compliance has not been confirmed.
Epic's thumbnail policy forbids showing elements absent from the island. A misleading thumbnail gets the island pulled from Discover, whatever its numbers.
Fix: Redo the thumbnail so it only shows environments, characters and mechanics actually present, then tick the box.
Update cadence too low
to fix
You have not said when the island was last updated.
Discover favours living islands. An island with no update for more than three months sees its engagement signals erode, and no metadata can compensate.
Fix: Plan one visible update a month, however small, and announce it in the description.
No tags
worth knowing
The tags field is empty.
Tags carry no weight on the rows, but they remain a signal for internal search. Leaving them empty is a missed opportunity, without being a mistake.
Fix: Add 5 to 8 tags using the vocabulary players in your genre actually use.

Rules passed (8 of 14)

Title too long
The word Fortnite in the title
Keyword stuffing in the title
Terms that get an island rejected
Description copied from the title
Description too short
Tags do not change the rows
Metadata repeating itself

What this tool does

Applies fourteen rules derived from Epic's Discover rules and its thumbnail policy.
Sorts findings by severity and gives a written fix for each one.
Shows the score computation point by point, with no hidden weighting.
Runs entirely in your browser: nothing is sent and nothing is stored.

What is still missing

No comparison with the real metadata of the islands performing in your genre.
No check on the thumbnail itself: compliance stays a box you tick.
The title length threshold is an observed order of magnitude, Epic publishes no figure.
