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 | $0.00413 |
| Opus 5 | $0.00000 | $0.00206 |
| Sonnet 5 | $0.00000 | $0.00083 |
| Haiku 4.5 | $0.00000 | $0.00041 |
Grade C, and why
vp-get-data-context 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 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.

VP Get data context ( vpAreaName : Text {; sheet : Integer } ) : any
| Parameter | Type | Description | |
|---|---|---|---|
| vpAreaName | Text | -> | 4D View Pro area form object name |
| sheet | Integer | -> | Index of the sheet to get the data context from |
| Result | Variant | <- | Data context. Object or Collection |
Description
The VP Get data context command returns the current data context of a worksheet. The returned context includes any modifications made to the contents of the data context.
In sheet, pass the index of the sheet to get the data context from. If no index is passed, the command returns the data context of the current worksheet. If there is no context for the worksheet, the command returns Null.
The function returns an object or a collection depending on the type of data context set with VP SET DATA CONTEXT.
Example
To get the data context bound to the following cells:
var $dataContext : Object
$dataContext:=VP Get data context("ViewProArea") // {firstName:Freehafer,lastName:Nancy}

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.
