🤖 OpenAI Codex can now build Slack apps.
The Slack Skills Plugin is available on Codex:
$ codex plugin marketplace add slackapi/slack-skills-plugin
$ codex plugin add slack@slack
The skills your agent picks up:
• create-slack-app - create a Bolt app (JS or Python) with the Slack CLI, install it, and start a live dev server.
• block-kit - design and validate rich messages instead of guessing at the schema.
• slack-cli - drive slack login, the dev server, deploys, and manifest edits.
• test-slack-app - exercise every feature of your app in a sandbox, not a real workspace.
• slack-api - call the Slack API straight from your coding agent.
• slack-docs - read the live docs, so answers are accurate instead of coming from the model's memory.
We're continuing to pave the whole agentic coding lifecycle: ideate, build, test, deploy, monitor.

❓ How are you using a coding agent with Slack?
Michael Brooks retweeted
Your AI coding tool knows code. Now it can know Slack, too. 🧠
The Slack Skills Plugin brings Slack-specific guidance directly into tools like Claude Code and @cursor_ai, helping you build with the right APIs and platform patterns.

One command closer to building in Slack. 💻
Install the Slack CLI, make sure everything’s up and running, and you’re ready to start building apps and AI agents.
See how easy it is to get started: docs.slack.dev/quickstart

Writing tests for agent apps built with the OpenAI Agents SDK is now much easier!
You can use the newly added, reusable ScriptedModel utility to mock model calls. See openai.github.io/openai-agen… for details.

🛠️ Slack Skills Plugin for Claude Code and Cursor - v1.1.0
We just shipped 4 developer skills for building Slack apps with AI coding agents.
What’s new:
→ Create Slack App - scaffold apps and agents
→ Block Kit - build and validate Block Kit layouts
→ Slack CLI - manage apps, local dev, and api requests
→ Slack API - call API methods with proper scopes, pagination, and error handling
When we shipped the Slack MCP Server, it covered runtime well - posting, reading, searching a workspace. What it didn’t cover was build-time. These four skills close that gap.
Install or upgrade:
→ Claude (Web, Cowork, Code): claude.com/plugins/slack
→ Cursor: one-click install github.com/slackapi/slack-mc…
