What it does

Migration is an agent skill from kortix-ai/suna. How to change the database schema in this repo. Current engine: node-pg-migrate, with SQL generated from Drizzle schema changes when possible. Load whenever you add/alter/drop a table, column, enum, index, constraint, RLS/function/grant, or any file under packages/db/migrations.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases, covering Database migrations, ORMs and data access and Database schema design. It works with SQL. The repository describes itself as: The open-source AI Operating System.

When your agent uses it

  • Tasks that involve Database migrations
  • Tasks that involve ORMs and data access
  • Tasks that involve Database schema design

Example prompts

  • “/migration”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Never edit a migration that has been applied anywhere. Write a new migration.
  2. Never use drizzle-kit push or hand-apply production DDL outside the migration
  3. Review every generated SQL file before it reaches a shared DB.
  4. Prefer expand/contract for destructive or compatibility-sensitive changes.
  5. Adding an index/dropping an index on an EXISTING table: use
  6. Prod is live: show the exact SQL and get explicit go-ahead before any manual

What it can do on your machine

Read from SKILL.md and the folder at commit 0d853bd. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pnpm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Migration loads about 1.2k tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 518 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 518 words (~1,166 tokens).

“The canonical, detailed runbook is packages/db/MIGRATIONS.md. This skill is a short safety wrapper; if anything here seems incomplete, trust that file and the current package.json scripts.”
