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.
Guaranteed Slots
There is always at least 1 Legendary, 1 Epic, and 1 Rare skill on the platform — as long as those skills have some engagement (score > 0). This ensures every rarity tier is visible, even when the community is small.
Percentile Caps
As the skill library grows past 20 skills, a percentile system kicks in: only the top 5% can be Legendary, top 15% Epic, and top 40% Rare. This keeps rarity meaningful — Legendary always means something.
Active Community
Score thresholds scale with the number of active users (people who downloaded or upvoted in the last 14 days). A skill needs both relative popularity (top percentile) and absolute engagement (real score) to rank up. No free rides.
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. ☕
