migrate

A database migration tool that detects the migration system used by a project and applies or reverses changes. A migration is a recorded change to a database structure, such as adding a table or column.

In plain words
What is it for?
Use it with projects using Make, golang-migrate, dbmate, Alembic, Prisma, Rails, Drizzle, or Knex to run migrations forward, roll them back, or inspect their state.
Why use it?
It removes the need to identify the project's database tool and remember its commands. It supports applying changes, rolling them back, checking status, and undoing a chosen number of steps where supported.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

migrate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Database Migrations

Apply or rollback database migrations with auto-detection of the migration tool.

Target

Parse the user's request to determine the action. Accepted formats: up, down, down N, status.

Step 1 — Detect Migration Tool

Scan the project for migration tool markers:

Marker Tool Apply Command Rollback Command
Makefile with migrate-up Make make migrate-up make migrate-down
Makefile with migrate Make make migrate make migrate-rollback
golang-migrate or numbered .sql pairs golang-migrate migrate -path <dir> -database $DB up migrate ... down 1
dbmate in deps or PATH dbmate dbmate up dbmate down
alembic.ini or alembic/ Alembic alembic upgrade head alembic downgrade -1
prisma/ + package.json Prisma npx prisma migrate deploy npx prisma migrate reset
db/migrate/ + Rakefile Rails rails db:migrate rails db:rollback
drizzle.config.ts Drizzle npx drizzle-kit push (manual)
knexfile.js / knexfile.ts Knex npx knex migrate:latest npx knex migrate:rollback

If a Makefile target exists for migrations, prefer it — it may include environment setup.

Step 2 — Execute Command

Based on the user's request:

up (default if no argument)

Apply all pending migrations:

<detected_apply_command>

down

Rollback the last migration:

<detected_rollback_command>

down N (e.g., "down 3")

Rollback N migrations:

  • golang-migrate: migrate ... down N
  • Alembic: alembic downgrade -N
  • Rails: rails db:rollback STEP=N
  • Knex: npx knex migrate:rollback --all (then migrate to target, or rollback N times in loop)

status

Show migration status:

  • golang-migrate: migrate ... version
  • Alembic: alembic current + alembic history
  • Prisma: npx prisma migrate status
  • Rails: rails db:migrate:status
  • dbmate: dbmate status

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

migrate is a skill published in the GitHub repository RaNDoM6913/claude-code-superkit (2 stars, last pushed 1mo ago), licensed MIT. It adds 15 tokens to every session and 783 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
