About AgentSpec

A public registry for everything that configures your AI coding agent.

AI coding agents — Claude Code, Codex, OpenCode, Cursor, Windsurf, GitHub Copilot, Cline, Gemini — all share a common need: good configuration. A well-written CLAUDE.md, a carefully scoped MCP server, or a battle-tested skill can make the difference between an agent that works and one that wastes tokens guessing.

AgentSpec collects, curates, and indexes these pieces from the community so you can discover what others use, install it in seconds, and share what works for you. Browse, vote, fork, or publish your own — every agent-ready artifact in one place.

What you’ll find

Configs

claude_code_config.json · codex.toml · opencode.json

JSON and TOML configuration templates for Claude Code, Codex, and OpenCode — the base settings that control model choice, tools, hooks, and permissions.

Skills

.claude/skills/ · .codex/skills/ · .opencode/skills/

SKILL.md documents that extend your agent with reusable workflows — accessibility audits, frontend patterns, testing strategies, and more.

Rules

CLAUDE.md · AGENTS.md · .cursorrules · .windsurfrules

Project-level instruction files that tell your agent how to behave inside a codebase — conventions, must-follow patterns, anti-patterns, commit style.

Plugins

Model Context Protocol servers · OpenCode plugins

MCP servers and agent plugins that add capabilities — database access, API integrations, custom tools, and automations.

Specs

"Next.js 15 full stack" · "Python data engineering"

Curated bundles that combine configs, skills, rules, and plugins into a single shareable preset. One-click install for complete agent setups.

How it works

Browse or search

Filter by agent, sort by hot / new / top / installs, or semantic search across titles and descriptions.

Preview safely

Every config, skill, and rule shows its full content before you install. Votes and install counts tell you what the community trusts.

Install anywhere

Copy-paste a shell one-liner, use the agentspec CLI, or manage everything visually in the desktop app. Files land in the correct directory for your agent — .claude/skills/, CLAUDE.md, or wherever it belongs.

Publish and iterate

Sign in with GitHub to publish your own. Each submission gets a revision history, votes, and a permanent URL you can share.
