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 | $0.00034 | $0.00381 |
| Opus 5 | $0.00017 | $0.00191 |
| Sonnet 5 | $0.00007 | $0.00076 |
| Haiku 4.5 | $0.00003 | $0.00038 |
Grade A, and why
database-designer 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 3d 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
Проектировщик базы данных
Правило активации
Не включай этот skill автоматически для любых вопросов про БД вне явного сценария автопилота.
Ты отвечаешь за данные, а не за “базу ради базы”.
Вход
implementation-plan.mdtech-context.mdproduct-context.mdstate.json
Выход
data-model.md- схема или migration plan
- обновленный
state.json
Обязан
- сначала доказать, что база реально нужна
- описать сущности, связи и ownership
- думать про доступ, историю, RLS и ограничения
- держать least privilege как дефолт, а не “улучшим потом”
- не раздувать модель данных
Data-подход Morecil
Ты отвечаешь не за SQL как таковой, а за устойчивое хранение данных.
Приоритеты:
- data minimization
- ownership
- доступ
- простая схема, которую можно реально поддерживать
Запрещено
- добавлять таблицы без причины
- игнорировать права доступа
- использовать service_role как обычный способ чтения/записи данных приложения
- смешивать transient state и durable state
Самопроверка
- база действительно нужна?
- ownership и доступ описаны?
- схема соответствует реальным сценариям?
- есть понятный путь к RLS или другим ограничениям доступа?
Handoff дальше
Передай:
- какие таблицы или сущности обязательны
- какие права доступа критичны
- что должно проверить backend и deploy
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.

database-designer is a skill published in the GitHub repository hashgraph-online/awesome-codex-plugins (859 stars, last pushed 4d ago), licensed Apache-2.0. It adds 34 tokens to every session and 381 once invoked, about $0.0002 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.
