Slack tool actions: send/read/edit/delete messages, react, pin/unpin, list pins/reactions/emoji, member info.
npx skills add Health-Yang/MineEcho --skill slack --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.

What does the slack skill do?
Slack tool actions: send/read/edit/delete messages, react, pin/unpin, list pins/reactions/emoji, member info.
How do I install it?
Run `npx skills add Health-Yang/MineEcho --skill slack --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From Health-Yang/MineEcho, a repository with 248 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
