Install target

Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned anthropics/knowledge-work-plugins at da38ec1ee8.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

The slack-messaging skill enables AI agents to send messages, create threads, and manage interactions directly within Slack channels. It facilitates seamless communication by allowing agents to post updates, ask questions, and share files without manual intervention.

When to use it

  • Automate routine status updates or meeting reminders for specific teams.
  • Trigger notifications in relevant channels when a project milestone is reached.
  • Enable an AI agent to answer FAQs directly in the #general or #support channels.
  • Coordinate real-time collaboration by posting links and resources to active threads.

Key capabilities

  • Compose and send text messages to public or private Slack channels.
  • Create new discussion threads to keep conversations organized.
  • Interact with existing messages via replies and reactions.
  • Share files and external links directly into the chat interface.

Example prompts

  • "Post a summary of today's sprint planning meeting in the #dev-ops channel."
  • "Reply to the latest message in the #customer-support thread with the troubleshooting steps for error 404."
  • "Share the link to the Q3 financial report and ask the team for their initial feedback in the #finance channel."

Tips & gotchas

Ensure your AI agent has the necessary bot permissions (e.g., chat:write, channels:history) before attempting to post messages. Be mindful of Slack's rate limits to avoid triggering spam filters during high-volume automated posting.
