Automated safety checks

scanned 28 Sept 2026

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

Declares what it does: failed
No SKILL.md was found in the skill's directory.
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

About this skill

What it does

This skill automates the process of updating a markdown file index, such as a table of contents or list of files in a documentation project. It can add, remove, or reorder entries based on user input and ensure proper formatting is maintained.

When to use it

You need to update a README.md or documentation index with new files or sections.
You want to reorganize the order of items in a markdown file without manually editing the list.
Your project has multiple markdown files, and you need an automated way to keep their index up-to-date.

Key capabilities

Adds or removes entries from a markdown file's index.
Maintains consistent formatting (e.g., bullet points, headers).
Supports reordering of items based on user-specified logic.

Example prompts

"Add 'Getting Started' as the first section in the README.md."
"Remove the 'Legacy Features' entry from the documentation index."
"Reorder the markdown file list alphabetically."

Tips & gotchas

Ensure that your markdown file is properly formatted before using this skill to avoid unexpected results.
This skill may not handle complex nested lists or custom formatting beyond basic bullet points and headers.
