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 | $0.00452 |
| Opus 5 | $0.00000 | $0.00226 |
| Sonnet 5 | $0.00000 | $0.00090 |
| Haiku 4.5 | $0.00000 | $0.00045 |
Grade C, and why
vp-get-active-cell scanned grade C with 1 finding 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 4d 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- REF #_method_.VP Get active cell.Syntax --> What it actually says
VP Get active cell ( vpAreaName : Text { ; sheet : Integer } ) : Object
| Parameter | Type | Description | |
|---|---|---|---|
| vpAreaName | Text | -> | 4D View Pro area form object name |
| sheet | Integer | -> | Sheet index (current sheet if omitted) |
| Result | Object | <- | Range object of single cell |
Description
The VP Get active cell command returns a new range object referencing the cell which has the focus and where new data will be entered (the active cell).
In vpAreaName, pass the name of the 4D View Pro area. If you pass a name that does not exist, an error is returned.
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.
Example
The following code will retrieve the coordinates of the active cell:
$activeCell:=VP Get active cell("myVPArea")
//returns a range object containing:
//$activeCell.ranges[0].column=3
//$activeCell.ranges[0].row=4
//$activeCell.ranges[0].sheet=0

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.
