slackapi/slack-skills-plugin ? reverse-engineered prompt

Build me a Slack plugin for Claude Code and Cursor that connects the AI to a Slack workspace through Slack’s hosted MCP server.

I want it to install cleanly in both tools, guide the user through Slack OAuth on first use, and then let the AI search messages, files, users, and channels, read and follow threads, send and schedule messages, react to posts, and work with canvases. It should also include helpful Slack skills for writing good Slack messages, searching Slack, using the Slack API, creating Slack apps, and building and validating Block Kit layouts.

Please add a few simple slash commands too, like summarizing a channel, finding discussions about a topic, drafting an announcement, generating a standup update, and creating a digest across channels.

Make it feel polished and easy to use, with good docs, examples, and sensible defaults. If you need to check current Slack docs or APIs while building it, go ahead and look them up online.
