Cross-agent skill registry that's actually curated, not scraped

dev tool real project •• multiple requests

There are now 4+ competing 'npm for AI agent skills' registries (Skills.sh, SkillsMP, ClaudeSkills.info, Agensi, awesome-agent-skills) and they mostly index by crawling GitHub for SKILL.md files. Devs running Claude Code, Codex CLI, Cursor, and Gemini CLI simultaneously want one trusted source where skills are tested against multiple agents, version-pinned, and not malware. Demand is for a curated layer over the scraped chaos, not yet another scraper.

builder note

The defensible play is the test matrix, not the catalog. Anyone can scrape SKILL.md files. Almost nobody is paying the compute bill to actually run each skill against four agents on every release and publish the pass/fail.

The category split: scrapers compete on volume, curators compete on trust. The under-served niche is 'I run three agents and want one skill that works in all of them with proof.' A small CI matrix that runs each submitted skill against the four major agents would be a moat.

Skills.sh Vercel-backed, fastest CLI install. But it's a distribution layer, not a curation/trust layer. No automated cross-agent compatibility tests, no malicious-skill scanning surfaced to end users.

SkillsMP 89K skills scraped from GitHub SKILL.md files. Volume is the product. Zero signal on whether any given skill actually works in Codex CLI vs Claude Code vs Cursor.

Agensi Closest to a vetted catalog, but paid-skill positioning means it leans toward commercial vendor skills, not the long tail of community workflows.

awesome-agent-skills (VoltAgent) Curated GitHub README. Discoverability stops at Ctrl+F. No install path, no compatibility matrix.
