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 | $0.00304 |
| Opus 5 | $0.00000 | $0.00152 |
| Sonnet 5 | $0.00000 | $0.00061 |
| Haiku 4.5 | $0.00000 | $0.00030 |
Grade C, and why
vp-get-spans 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.

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 spans.Syntax --> What it actually says
VP Get spans ( rangeObj : Object ) : Object
| Parameter | Type | Description | |
|---|---|---|---|
| rangeObj | Object | -> | Range object |
| Result | Object | <- | Object of cell spans in the defined range |
Description
The VP Get spans command retrieves the cell spans in the designated rangeObj.
In rangeObj, pass a range of cell spans you want to retrieve. If rangeObj does not contain a cell span, an empty range is returned.
Example
You want to center the text for the spanned cells in this document:
// Search for all cell spans
$range:=VP Get spans(VP All("ViewProArea"))
//center text
$style:=New object("vAlign";vk vertical align center;"hAlign";vk horizontal align center)
VP SET CELL STYLE($range;$style)

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-get-spans 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 304 tokens. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
