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 | $0.00027 | $0.01272 |
| Opus 5 | $0.00014 | $0.00636 |
| Sonnet 5 | $0.00005 | $0.00254 |
| Haiku 4.5 | $0.00003 | $0.00127 |
Grade A, and why
pgd 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.
How it starts
The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PGD — pgDesigner формат и CLI
.pgd — git-friendly XML-формат pgDesigner для схем PostgreSQL.
Полная спецификация: https://pgdesigner.io/docs/pgd-format (XSD: pgd-format.xsd).
CLI: pgdesigner (не pgd).
Non-obvious правила редактирования
- Без числовых ID — объекты по имени; кросс-схемно через
schema.table <index>— на уровне<schema>, НЕ внутри<table>(частая ошибка при конверсии из PDD)- Порядок элементов в
<table>ломает диф: columns → pk → fk → unique → check → exclude → with → partition-by → partition - Булевы — строки
"true"/"false"(не"0"/"1"как в PDD) - SQL всегда в CDATA — CHECK, WHERE, тела функций, generated-выражения, bound партиций
nullabledefault"true"— для NOT NULL ставь явноnullable="false"- Атрибуты на одной строке — иначе git-diff будет шумный

Канонические сниппеты
Enum (редактор восстанавливает порядок <label> — ручная перестановка не ломает):
<enum name="user_status" schema="public">
<label>active</label>
<label>inactive</label>
</enum>
FK (inline в <table>, в отличие от PDD):
<fk name="fk_orders_user" to-table="users" on-delete="cascade" on-update="no action">
<column name="user_id" references="id"></column>
</fk>
Индекс по выражению / partial / covering:

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.

pgd is a skill published in the GitHub repository vmkteam/claude-plugins (7 stars, last pushed 4mo ago), licensed MIT. It adds 27 tokens to every session and 1,272 once invoked, about $0.0001 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 2026-08-31.
