Helps with creation, database, migration as part of working with databases and data persistence workflows.

Repository

Install on your platform

Showing Claude Code. One command installs this skill into any of the agents below.

Installs under a different name. Its SKILL.md names it Create database migration, not the name it is listed under, so the command below uses that name.
  1. 1

    Run this in your project

    terminal
    $ npx skills add tryghost/ghost --skill "Create database migration" -a claude-code

  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

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 tryghost/ghost at 5f7535aa0c.

    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 generates SQL migration scripts to safely alter your database schema. It handles creating new tables, modifying existing columns, and managing foreign key constraints based on your specific requirements.

When to use it

  • You need to add a new column to an existing table without losing current data.
  • You are refactoring your schema by splitting one large table into multiple related tables.
  • You require a reversible migration script for testing or deployment pipelines.
  • You want to ensure foreign key relationships are defined correctly during schema changes.

Key capabilities

  • Generates standard SQL ALTER TABLE statements for column modifications.
  • Creates new table definitions with appropriate data types and constraints.
  • Handles complex operations like adding foreign keys and indexes.
  • Produces migration files suitable for frameworks like Knex or raw SQL execution.

Example prompts

  • "Create a database migration to add an email_verified boolean column to the users table."
  • "Write a migration script to split the orders table into order_items and order_headers with proper foreign keys."
  • "Generate a migration to rename the username column to handle in the accounts table and update existing values."

Tips & gotchas

Ensure your AI agent knows the current schema structure, as it cannot infer existing columns or constraints without that context. Always review generated SQL before running it in production, especially when altering data types or removing columns, as these operations can be destructive.
