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 5.1 | $0.00009 | $0.02220 |
| Opus 5.5 | $0.00004 | $0.00888 |
| Sonnet 5.5 | $0.00002 | $0.00444 |
| Haiku 4.5 | $0.00001 | $0.00222 |
Grade A, and why
db-migrate 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 340 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Создай database migration следуя лучшим практикам.
ВАЖНО: Миграции - критическая часть. Тестируй все тщательно!
Процесс:
1. Анализ текущей схемы БД
Прочитай и проанализируй:
# Найди файлы схемы БД
find . -name "schema.*" -o -name "*.prisma" -o -name "*migration*"
# Посмотри последние миграции
ls -la supabase/migrations/ || ls -la prisma/migrations/ || ls -la migrations/
Прочитай:
- Текущую схему БД
- Последние миграции
- Database documentation (если есть в ARCHITECTURE.md)
2. Пойми требования
Спроси себя:
- Какие изменения в схеме нужны?
- Есть ли существующие данные, которые нужно сохранить?
- Нужна ли обратная совместимость?
- Есть ли зависимости от других таблиц?
3. Спланируй миграцию
Типы изменений:
Безопасные (можно делать на проде):
- ✅ ADD column (с DEFAULT или NULL)
- ✅ ADD index (concurrent)
- ✅ ADD new table
- ✅ ADD constraint (NOT VALID, потом VALIDATE)
Опасные (требуют осторожности):
- ⚠️ DROP column (может сломать приложение)
- ⚠️ RENAME column (нужна двухфазная миграция)
- ⚠️ CHANGE column type (может потерять данные)
- ⚠️ ADD NOT NULL (сначала заполни данные)
Очень опасные (только с downtime):
- 🔴 DROP table
- 🔴 CHANGE primary key
- 🔴 Большая структурная переделка
4. Создай migration файл
Naming convention:

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.
- 2mo ago First seen · 340 lines · 9 tokens per session scan A cb9a2b836b5b
db-migrate is a command published in the GitHub repository AI-agents-incubator/n8n-pilot (30 stars, last pushed 29d ago), licensed MIT. It adds 9 tokens to every session and 2,220 once invoked, about $0.0000 per session on Opus 5.5. 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 2026-09-04.
