Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

By slackapi/slack-mcp-plugin (GitHub) · coding · 165 stars · scanned at commit 99e027a

Use when a developer wants to create, scaffold, or bootstrap a new Slack app or agent from scratch with the Slack CLI, or scaffold the project for a new app just created in App Settings (`--app`, `--template`, `--team`). 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".

Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'create-slack-app' ] || [ -L ~/.agents/skills/'create-slack-app' ]; then echo 'A skill folder named create-slack-app already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/slackapi/slack-mcp-plugin' "$d" && git -C "$d" checkout --quiet '99e027a47c065223ac719a1b291997d4fc23cec0' -- 'skills/create-slack-app' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/create-slack-app' ~/.agents/skills/'create-slack-app' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'create-slack-app' ~/.claude/skills/'create-slack-app' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
