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 onewave-ai/claude-skills at f317e08649.

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

About this skill

What it does

This skill allows AI agents to format messages specifically for Slack, ensuring posts render correctly with proper styling and structure. It transforms raw text or code into optimized Slack-compatible formats that preserve readability and visual hierarchy within the platform.

When to use it

  • Sending code snippets or logs that require monospaced font rendering without markdown stripping.
  • Posting structured data like tables, bullet points, or bold headers in a professional channel.
  • Ensuring complex formatting (like emojis or specific link styles) displays exactly as intended by Slack's native parser.

Key capabilities

  • Converts standard text into Slack-compatible markup language.
  • Preserves code blocks and syntax highlighting within chat messages.
  • Optimizes message structure for better mobile and desktop rendering on Slack clients.

Example prompts

  1. "Format this Python error log so it displays correctly in our #dev-ops Slack channel."
  2. "Create a formatted announcement post about the new holiday schedule with bold headers and bullet points."
  3. "Convert this JSON data object into a readable table format suitable for posting in Slack."

Tips & gotchas

  • Ensure your AI agent has access to the specific Slack workspace context if it needs to reference channel-specific formatting rules or custom emojis.
  • While this skill handles standard Slack markup, extremely complex HTML elements may still require manual verification before posting.
