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 aj-geddes/useful-ai-prompts at 3f5182cfd7.

    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 data-migration-scripts skill provides AI agents with the ability to generate, execute, and manage database migration scripts for various SQL dialects. It automates the creation of complex schema changes, data transformations, and rollback procedures to ensure safe transitions between database versions.

When to use it

  • Automating routine database updates in CI/CD pipelines to reduce manual deployment errors.
  • Generating idempotent migration scripts that can be safely re-run without causing duplicate data entries.
  • Creating comprehensive rollback strategies to revert schema changes if a migration fails during production deployment.
  • Standardizing SQL syntax across different environments (e.g., MySQL, PostgreSQL) for consistent application behavior.

Key capabilities

  • Generates valid SQL CREATE, ALTER, and DROP statements tailored to specific database engines.
  • Produces data transformation logic for migrating records between incompatible table structures.
  • Creates transactional blocks to ensure atomicity during critical migration steps.
  • Outputs detailed rollback scripts to reverse changes instantly upon failure detection.

Example prompts

  • "Generate a PostgreSQL migration script to add a created_at timestamp column to the users table with a default value of the current time."
  • "Write an idempotent SQL script to migrate email addresses from a VARCHAR(50) field to a normalized TEXT format in a MySQL database."
  • "Create a migration and rollback pair for splitting a monolithic orders table into separate order_items and order_headers tables while preserving historical data integrity."

Tips & gotchas

Ensure your AI agent specifies the target SQL dialect (e.g., PostgreSQL, MySQL) in the prompt, as syntax varies significantly between engines. Always review generated scripts in a staging environment before applying them to production databases to verify data consistency and performance impact.
