What it does

Migration Helper is an agent skill from pilinux/gorest. Analyze GORM model changes, estimate resulting schema (DDL) differences, and propose safe migration steps with verification guidance.

Its SKILL.md is about 360 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. The repository describes itself as: Go RESTful API starter kit with Gin, JWT, GORM (MySQL, PostgreSQL, SQLite), Redis, Mongo, 2FA, email verification, password recovery. The licence is MIT.

When your agent uses it

  • Databases work in your project

Example prompts

  • “/migration-helper”

Workflow steps

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

  1. Locate migration entrypoints in the paths above.
  2. Map model edits to likely DDL changes and affected queries.
  3. Recommend migration steps and verification commands (local + staging).

What it can do on your machine

Read from SKILL.md and the folder at commit 38aab64. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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 Helper loads about 358 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 141 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~358

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.

Migration Helper

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

  1. Locate migration entrypoints in the paths above.
  2. Map model edits to likely DDL changes and affected queries.
  3. 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?"
  • db-infra-mocks, test-runner, patch-applier
