Install

Skills CLI

npx skills add slackapi/slack-skills-plugin

Asks which skills and agents to install. Just one: npx skills add slackapi/slack-skills-plugin --skill block-kit — add -g for every project.

Claude Code

git clone https://github.com/slackapi/slack-skills-plugincp -r "slack-skills-plugin/skills/block-kit" ~/.claude/skills/

Copies the block-kit skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add slackapi/slack-skills-plugin

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • block-kit

    Use when a developer wants to build or validate Block Kit layouts for Slack messages, modals, or Home tabs: message layouts, modals/forms/dialogs, Home tab interfaces, interactive buttons or menus, or modifying existing Block Kit JSON. Also trigger on any Slack UI component (sections, actions, inputs, headers, alerts, tables, carousels), the words "blocks" or "Block Kit Builder", a request to pre…

  • create-slack-app

    Use when a developer wants to create, scaffold, or bootstrap a new Slack app or agent from scratch with the Slack CLI. Covers prerequisites, authentication, choosing a workspace to install into, and creating a project from a Bolt (JS or Python) template locally. Trigger on "create a Slack app", "new Bolt app", "start a Slack agent".

  • slack-api

    Use when a developer asks which Slack Web API method does something, needs a method's OAuth scopes or token type, wants to call or test a family.method endpoint (chat.postMessage, conversations.history, users.info, views.open), is handling cursor pagination (next_cursor) or rate limits (tier/ratelimited/Retry-After), or is debugging errors like missing_scope, invalid_auth, or channel_not_found. A…

  • slack-cli

    Use when a developer works with the Slack CLI (slack command) to create, run, or manage a Slack app from the terminal: logging in or authenticating (slack login), adding a team or switching workspaces, running locally (slack run), deploying, editing the app manifest, calling Web API methods (slack api), or searching Slack docs (slack docs search).

    skills/slack-cli/SKILL.md on GitHub (opens in a new tab)

  • slack-docs

    Use when answering a conceptual or how-to question about Slack platform features, or when asked to look up, fetch, or summarize a docs.slack.dev page, including a pasted docs.slack.dev link. Covers finding and reading official Slack docs as clean markdown.

  • slack-messaging

    Use when writing, drafting, scheduling, or improving a Slack message, announcement, or reply sent via the Slack MCP tools (slack_send_message, slack_send_message_draft, slack_schedule_message). Covers Slack markdown formatting, message structure, thread etiquette, reactions, and scheduling, and points to the right dialect for canvases and Block Kit.

  • slack-search

    Use when locating messages, files, channels, or people across Slack, or gathering context before answering, with the search MCP tools (slack_search_public, slack_search_public_and_private, slack_search_channels, slack_search_users). Covers search modifiers (in:, from:, before:), file-type filters, natural-language vs. keyword search, and reading results in context.

    skills/slack-search/SKILL.md on GitHub (opens in a new tab)

  • test-slack-app

    Use when a developer wants to test, try out, smoke-test, verify, or confirm that a Slack app built with the Slack CLI (or a plain Bolt app) actually works, by running it in a developer sandbox or a Free Team, never a workspace with real users, with `slack run` and exercising its real slash commands, shortcuts, events, actions, modals, App Home, and assistant surfaces. Also covers `slack doctor` a…

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
