An image annotation tool that places a numbered grid over a PNG or JPG image. The grid has marked vertical and horizontal lines for estimating positions and proportions.

In plain words
What is it for?
Use it to inspect screenshots and printed forms, measure column positions, and plan table-document layouts.
Why use it?

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 10d 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.

Origin

This is a copy

100% identical to img-grid — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/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 ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
