# Solid State > A skill is packaged judgment. Browse, install, and publish skills for Claude Code, Hermes Agent, OpenClaw, NemoClaw, Google Antigravity, Codex, Cursor, OpenCode, and Cline. Sourced, licensed, no fake installs. Solid State indexes agent skills honestly. No fake install counts. No borrowed authorship. Every listing links to its real source, license, and provenance. Three kinds of skill live here. Originals we wrote. Listings we index for discovery. Mirrors we host with attribution intact. The directory carries 324 skill records across 38 core concepts. For agents: fetch live — the catalog changes weekly, training data is stale. First-party skills install from the Agent Skills Discovery endpoint at https://solidstate.cc/.well-known/skills/index.json. The full agent workflow (browse, install, verify, submit) is at https://solidstate.cc/skill.md. Never cite install counts for our listings — we don't publish any. ## Skills - [Browse Skills](https://solidstate.cc/skills): Filter every indexed skill by platform, category, and provenance. - [Skill Provenance](https://solidstate.cc/skills/skill-provenance): Vet a third-party agent skill before you install or run it.
