db-migrate

db-migrate is a command for coding agents from rohitg00/awesome-claude-code-toolkit. It costs 13 tokens per session (289 once invoked), scanned A, original, Apache-2.0.

A command for generating a database migration, a controlled set of changes that updates a database schema over time. It supports common tools such as Prisma, Drizzle, Knex, Alembic, Django, and GORM.

In plain words
What is it for?
Use it to add or change tables, columns, constraints, defaults, indexes, and foreign keys. It creates forward and reverse steps, validates the change, and can perform a dry run.
Why use it?
It helps apply schema changes in a tracked and reversible way while accounting for data that may need to be moved. This lowers the risk of mismatched application and database structures.

Getting it into your agent

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

db-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.

What it actually says

Generate a database migration file for schema changes.

Steps

  1. Detect the ORM or migration tool in use (Prisma, Drizzle, Knex, Alembic, Django, GORM).
  2. Analyze the requested schema change:
    • Add/remove tables or columns.
    • Modify column types, constraints, or defaults.
    • Add/remove indexes or foreign keys.
  3. Generate the migration file in the correct format for the tool.
  4. Include both up and down migration functions for reversibility.
  5. Handle data migrations if column types change:
    • Add new column, copy data, drop old column, rename new column.
  6. Validate the migration against the current schema state.
  7. Run the migration in dry-run mode if the tool supports it.

Format

Migration: <YYYYMMDDHHMMSS>_<description>
Tool: <ORM/migration tool>

Up:
  - <change description>

Down:
  - <reverse change>

Data migration required: <yes/no>

Rules

  • Every migration must be reversible with a down function.
  • Never drop columns or tables without a data backup step.
  • Use transactions for multi-step migrations when supported.
  • Test migrations against a copy of production data structure.
  • Name migrations with timestamps to prevent ordering conflicts.
Changes

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.
