These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

img-grid 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/overlay-grid.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

/img-grid — Сетка для анализа макета

Накладывает пронумерованную сетку на изображение печатной формы. Позволяет точно определить границы колонок, их пропорции и span-ы для генерации макета табличного документа.

Использование

/img-grid <ImagePath> [-c COLS] [-o OUTPUT]

Параметры

Параметр Обязательный По умолчанию Описание
ImagePath да Путь к изображению (PNG, JPG)
-c COLS нет 50 Количество вертикальных делений
-r ROWS нет авто Количество горизонтальных делений (авто = квадратные ячейки)
-o OUTPUT нет <name>-grid.<ext> Путь для результата

Команда

python "${CLAUDE_SKILL_DIR}/scripts/overlay-grid.py" "<ImagePath>" [-c 50] [-o "<OutputPath>"]

Требуется Python 3 с библиотекой Pillow (pip install Pillow).

Что делает

  1. Рисует полупрозрачные вертикальные (красные) и горизонтальные (синие) линии
  2. Нумерует линии в отдельных полях сверху и слева (не перекрывает содержимое)
  3. Каждая 5-я и 10-я линия выделены ярче для удобства счёта

Как использовать результат

1. Определить границы колонок

Посмотреть на изображение с сеткой и записать координаты вертикальных границ каждой колонки таблицы (в номерах grid-линий).

2. Найти базовую решётку

Если на форме несколько таблиц с разной раскладкой (например, шапка документа и основная таблица), объединить все граничные точки. Каждый сегмент между соседними границами — одна колонка MXL.

Пример для М-11:

  • Шапка: границы 0, 2, 4, 9, 14, 21, 28, 34, 40, 48
  • Таблица: границы 0, 2, 4, 11, 16, 19, 23, 28, 32, 36, 42, 48
  • Объединение: 0, 2, 4, 9, 11, 14, 16, 19, 21, 23, 28, 32, 34, 36, 40, 42, 48
  • Результат: 16 базовых колонок с пропорциями 2, 2, 5, 2, 3, 2, 3, 2, 2, 5, 4, 2, 2, 4, 2, 6

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.
