How Skills Are Scored
Every indexed skill is placed into one of four quality tiers, and separately tagged with a risk level and a maintenance status. Together, these three signals are what you see next to each entry in the directory.
Quality tiers#
| Badge | Tier | Score | Description |
|---|---|---|---|
| ⭐ | Curated | ≥120 | High-viability with gotchas, examples, verification |
| 🔷 | Promising | 80–119 | Good structure, some quality signals |
| 🔶 | Experimental | 40–79 | Basic skill, limited signals |
| — | Review Required | <40 | Needs review |
Of the 1,204 skills currently indexed, 229 sit in the Curated tier — roughly one in five. That ratio is deliberate: the score gates on structure (documented gotchas, working examples, a verification step) before it counts adoption at all, so a skill can't buy its way into Curated on stars alone.
Risk levels#
Risk is scored independently of quality — a well-structured skill can still request broad permissions.
| Icon | Level | Description |
|---|---|---|
| 🟢 | Low | Standard permissions, safe to use |
| 🟡 | Medium | Extended permissions (shell access, subagents) |
| 🔴 | High | Broad system access, review before use |
| ⚫ | Critical | Manual review required |
Check the risk icon before installing a skill that will run inside your coding agent — a Curated quality score says nothing about how much system access the skill asks for.
Maintenance status#
| Icon | Status | Description |
|---|---|---|
| 🟢 | Active | Updated within last 90 days |
| ✅ | Stable | Feature-complete with releases |
| 🟠 | Stale | 90–365 days without updates and no releases |
| 🔴 | Unmaintained | Not updated for over 365 days |
| ⚪ | Unknown | No commit date available |
Maintenance status is recalculated daily, so a skill's badge moves as its upstream repository changes — a skill doesn't stay Active by default, it has to keep shipping.
