About

sidecar-cowork-plugins is a single-plugin Claude Code marketplace published under Sidecar for people who operate or serve associations and member-driven organizations. The sidecar-association-coworker plugin advertises slash commands and specialized guidance across membership lifecycle, governance, events, communications, advocacy, and related workflows for professional societies, trade associations, enthusiast clubs, fraternal groups, chambers of commerce, standards bodies, alumni networks, and similar entities. developers who consult for nonprofits or ship association-management products can register this marketplace to keep domain workflows inside Claude Code rather than generic chat prompts. It is not frontend scaffolding, SEO tooling, or an MCP data connector catalog. Intermediate complexity reflects navigating broad domain coverage and matching slash commands to real org processes.
