ag-migrar-dados

ag-migrar-dados is a skill for Claude Code from andregusman-raiz/a-gusman-claude. It costs 36 tokens per session (477 once invoked), scanned A, original, MIT.

A tool for creating and checking database migration files, which describe changes to a database's tables, indexes, or constraints. It detects the project's database toolkit and uses its native format.

In plain words
What is it for?
Use it when adding tables, changing columns, adding indexes, or backfilling existing data. It supports Supabase, Prisma, Drizzle, SQL Server, and other database migration work when the relevant official tool does not cover it.
Why use it?
It helps apply schema changes in a consistent way and catches conflicts with existing constraints, indexes, or migration timestamps. It is also useful when a project uses more than one database system.

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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

ag-migrar-dados 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 9d ago.

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.

What it actually says

ag-migrar-dados — Migrar Dados

Canonical delegation (ADR-0001)

Para Supabase, preferir skill oficial:

Caso Canonical
Supabase migrations (schema, RLS, Edge Functions) supabase:supabase
Postgres best-practices, performance tuning supabase:supabase-postgres-best-practices
Prisma/Drizzle migrations (não-Supabase) esta machine (ag-migrar-dados)
SQL Server (TOTVS RM), MSSQL esta machine + ag-12-sql-totvs-zeev

Esta machine mantém valor para projetos não-Supabase, migrations multi-DB, e contextos onde skill oficial não cobre (TOTVS RM, MSSQL).

Spawn the ag-migrar-dados agent to create and validate database schema migrations.

Invocation

Use the Agent tool with:

  • subagent_type: ag-migrar-dados
  • mode: auto
  • run_in_background: false
  • prompt: Compose from template below + $ARGUMENTS

Prompt Template

Projeto: [CWD or user-provided path]
Schema change: [descricao da mudanca — nova tabela, alteracao, backfill]
ORM: [supabase, prisma, drizzle, ou "auto-detect"]


Gerar migration com naming YYYYMMDDHHMMSS_descricao.sql, verificar conflitos de timestamp, constraints e indices existentes.
Incluir RLS policies e rollback. Validar antes de aplicar.

Important

  • ALWAYS spawn as Agent subagent — do NOT execute inline
  • After spawning, confirm to the user
  • NOT background — migrations require sequential validation
  • Supports modes: criar (new table), alterar (modify), backfill (data), validar (check pending)
  • Always includes RLS policies and rollback plan

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.
