When to Use

A model change (field add/remove/type change) or migration code is proposed and you need a safe rollout plan.

Rules

Start with a non-destructive assessment and clearly call out destructive operations (drops, type narrows, index changes).
Recommend backups, staging verification, and zero-downtime considerations for risky changes.

Project-Specific Paths

Core migration: database/migrate/
Example app migration: example2/internal/database/migrate/
Core models: database/model/ (Auth, TwoFA, TwoFABackup, TempEmail)

Workflow

Locate migration entrypoints in the paths above.
Map model edits to likely DDL changes and affected queries.

01When to Use 02

Recommend migration steps and verification commands (local + staging).

Output

Affected models: path:line entries.
Schema updates: likely DDL changes and risk level (low/medium/high).
Verification: steps and test commands.

Examples

"Adding a Role field to Auth model - what migration is needed?"
"Changing IDAuth from uint64 to uint32 - what are the risks?"
