slack-skills-plugin
Slack's own plugin for Claude Code, Cursor and Codex.
What it does
Slack's own plugin for Claude Code, Cursor and Codex. In Claude Code and Cursor it sets up a connection to Slack's hosted MCP server, which asks the user to sign in to their workspace with OAuth on first use, and it adds nine skills plus five slash commands. The skills cover writing and searching messages, calling Slack Web API methods, finding developer docs, using the Slack CLI, and creating, testing and deploying Slack apps, along with building Block Kit layouts. The commands summarise channels, find discussions, draft announcements and produce standup notes. Codex currently receives the skills only, and other agents can install the skills alone with npx skills.
