Skill Rarities

How skill popularity works on SkillCraft

The Four Tiers

Every skill on SkillCraft has a rarity tier based on how popular it is with the community. Rarity is not set by the author — it's earned through real engagement.

Common

Starting tier. Every skill begins here.

Rare

Getting traction. People are finding this useful.

Epic

Widely used. A community favourite.

Legendary

The best of the best. Extremely rare.

How It Works

Each skill has a popularity score calculated from community engagement:

score = downloads + (upvotes × 3)

Upvotes count 3× more than downloads because an upvote is a deliberate signal — someone tried the skill and thought it was good enough to recommend.

Downloads count once per user per skill. Downloading the same skill twice doesn't inflate the score.

The Ranking System

Rarity isn't based on fixed thresholds — it's a hybrid system that adapts to the size of the community.

Percentile Caps

Only the top 2% of skills can be Legendary, the next 10% Epic, and the next 25% Rare — everyone else is Common. Tier sizes recompute as the library grows, so rarity stays scarce at any size. A small library may have no Legendary at all; the first slot opens at 50 skills.

Verified Skills Only

Skills compete for tiers only after a human review. Unverified skills show an "unverified" badge instead of a tier and don't take up tier slots. Zero-engagement skills are always Common — rarity has to be earned by real downloads and upvotes.

Rarity Can Change

Rarity is recalculated every time someone downloads or upvotes a skill. That means:

  • A skill can climb from Common to Legendary as it gains traction
  • A skill can drop tiers if newer skills overtake it
  • Removing an upvote can affect rarity
  • All skills are re-ranked together — it's a leaderboard, not a badge

Want Your Skill to Rank Up?

Build something genuinely useful. Skills that solve real problems get downloaded and upvoted naturally. There are no shortcuts — the system is designed to reward quality over gaming.

The best skills tend to be specific (not generic), well-structured (clear instructions), and honest about what they do.

The rarity system is inspired by collectible card games — because marketing skills should be fun to collect. ☕
