 A collection of agent skills for getting an AI plugin into the stores, found and picked. Built for developers who ship ChatGPT apps, Claude plugins and connectors, Cursor plugins and MCP servers, and want their coding agent to help with submission, listing copy, discoverability, widget design and competitor tracking. Works with Claude Code, Codex, Cursor and any agent that supports [Agent Skills](https://agentskills.io).
