sql-migrations

Rules for introducing SQL files and database migrations into the cursor-doctor project. A migration is a tracked database change, such as creating a table or adding a column.

In plain words
What is it for?
Use them when adding database schema or data changes to choose filenames, write safe SQL, apply changes in order, document rollback plans, and update project documentation.
Why use it?
They reduce migration mistakes by requiring ordered, focused, repeatable changes and documentation of related architecture and data-model updates.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 226 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

sql-migrations 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

SQL Migration Conventions

cursor-doctor currently has no database schema or migrations. If SQL artifacts are introduced, follow this policy.

File naming

  • Use ordered filenames, for example 001-init.sql, 002-add-indexes.sql.
  • Keep one migration concern per file.

Idempotency

  • Prefer IF NOT EXISTS / IF EXISTS guards where supported.
  • Use upsert patterns (ON CONFLICT) for seed/reference data.
  • Avoid destructive statements unless explicitly documented and approved.

Execution discipline

  • Apply schema changes before data backfills.
  • Wrap dependent operations in explicit transactions where safe.
  • Document rollback strategy in migration comments or companion docs.

Documentation updates

  • Update docs/ARCHITECTURE.md and docs/DATA_MODEL.md when schema is added or changed.

Completeness checklist

  • migration location and naming
  • idempotent patterns
  • write order if applicable
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.
