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 frizzle-chan/mudd at 202a314da4.

    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

What it does

This skill automates database migrations in PostgreSQL. It allows you to apply, rollback, and manage changes to your database schema in a controlled and versioned manner. This ensures consistent database state across different environments and simplifies deployments.

When to use it

  • You need to update the structure of your PostgreSQL database (e.g., adding tables, columns, or indexes).
  • You want to safely revert changes made to your database schema if an issue arises during deployment.
  • Your development team follows a version-controlled approach for database modifications.
  • You are deploying applications across multiple environments (development, staging, production) and need consistent schemas.

Key capabilities

  • Apply migrations to update the database schema.
  • Rollback migrations to revert changes.
  • Manage migration versions.

Example prompts

  • "Run the latest pending PostgreSQL migrations."
  • "Revert the last applied PostgreSQL migration."
  • “Show me a list of all available PostgreSQL migrations.”

Tips & gotchas

This skill requires a working PostgreSQL database and access to its command line tools. Ensure that you have appropriate permissions to modify the database schema before using this skill.
