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 | $0.00000 | $0.00640 |
| Opus 5 | $0.00000 | $0.00320 |
| Sonnet 5 | $0.00000 | $0.00128 |
| Haiku 4.5 | $0.00000 | $0.00064 |
Grade A, and why
vp-cells 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
VP Cells ( vpAreaName : Text ; column: Integer ; row: Integer ; columnCount : Integer ; rowCount : Integer { ; sheet : Integer } ) : Object
| Release | Changes |
|---|---|
| 17 R4 | Added |
| Parameter | Type | Description | |
|---|---|---|---|
| vpAreaName | Text | -> | 4D View Pro area form object name |
| column | Integer | -> | Column index |
| row | Integer | -> | Row index |
| columnCount | Integer | -> | Number of columns |
| rowCount | Integer | -> | Number of rows |
| sheet | Integer | -> | Sheet index (current sheet if omitted) |
| Result | Object | <- | Range object of cells |
Description
The VP Cells command returns a new range object referencing specific cells.
In vpAreaName, pass the name of the 4D View Pro area. If you pass a name that does not exist, an error is returned.
The column parameter defines the first column of the cell range. Pass the column index (counting begins at 0) in this parameter. If the range is within multiple columns, you should also use the columnCount parameter.
In the row parameter, you can define the row(s) of the cell range's position. Pass the row index (counting begins at 0) in this parameter. If the range is within multiple rows, you should also use the rowCount parameter.
The columnCount parameter allows you to define the total number of columns the range is within. columnCount must be greater than 0.
The rowCount parameter allows you to define the total number of rows the range is within. rowCount must be greater than 0.
In the optional sheet parameter, you can designate a specific spreadsheet where the range will be defined (counting begins at 0). If omitted or if you pass vk current sheet, the current spreadsheet is used by default.
Example
You want to define a range object for the following cells (on the current sheet):
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.

vp-cells is a command published in the GitHub repository Ganbin/4d-development-skill (9 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 640 tokens. 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.
