copilot-setting: Command for GitHub Copilot

.github/prompts/generate-migration-sql.prompt.md

generate-migration-sql is a command for GitHub Copilot from zexion7873/copilot-setting. It costs 15 tokens per session (153 once invoked), scanned A, original, MIT.

A generator for MySQL database migration scripts and their rollback scripts, based on changes to Hibernate mapping files or entity classes. It can also include statements for moving data when columns are renamed or merged.

In plain words
What is it for?
Use it when changing columns, indexes, foreign keys, or mapped entities in a MySQL database. It helps prepare reversible schema and data changes.
Why use it?
Database schema changes need an ordered change and a safe way to undo it. The generated output separates migration from rollback and follows the project's stated schema-safety instructions.

Command for GitHub Copilot

Written for GitHub Copilot: a Copilot chat mode or prompt.

This is zexion7873/copilot-setting's own configuration. It tells GitHub Copilot how to work on copilot-setting itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything copilot-setting configures →

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

generate-migration-sql 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 1mo 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

Generate a MySQL migration script from this hbm.xml or entity change:

  1. ALTER TABLE statements (add / modify / drop columns, indexes, FKs)
  2. Corresponding rollback script (reversible DDL)
  3. Data migration statements (if columns are renamed or merged, data must be moved)

Rules:

  • Follow the schema conventions and migration-safety rules in instructions/sql-ddl.instructions.md (naming, ALGORITHM=INSTANT, idempotent chunked backfill, expand-contract renames, running-app compatibility) — do not restate them here
  • Write migration first, then rollback, clearly separated
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.
