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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00352 | $0.00352 |
| Opus 5 | $0.00176 | $0.00176 |
| Sonnet 5 | $0.00070 | $0.00070 |
| Haiku 4.5 | $0.00035 | $0.00035 |
Grade A, and why
drizzle-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 2d 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
Drizzle Migration Guidelines
Migration Generation
- ALWAYS use
npm run generateto create migrations- Never create migration files manually
- This ensures consistent migration file naming and structure
- Drizzle-kit will automatically detect schema changes
- Example:
npm run generatewill execute drizzle-kit generate command
Migration Best Practices
-
Review Generated Migrations
-- ✅ DO: Review and verify generated migrations ALTER TABLE "customers" ADD COLUMN "status" text DEFAULT 'new_customer'; -- ❌ DON'T: Manually modify generated migration files -- Let drizzle-kit handle the migration generation -
Version Control
- Commit migration files along with schema changes
- Never modify committed migrations
- Create new migrations for additional changes
Migration Commands
npm run generate- Generate new migrationsnpm run migrate- Apply pending migrationsnpm run studio- Open Drizzle Studio for database inspection
Migration Workflow
- Make changes to schema files in
db/schema/ - Run
npm run generateto create migration - Review generated migration file
- Run
npm run migrateto apply changes - Commit both schema and migration files

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.

drizzle-migrations is a cursor rule published in the GitHub repository squirrelogic/cursor-rules (20 stars, last pushed 1y ago), licensed MIT. It adds 352 tokens to every session, about $0.0018 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
