What is browsercard-reference?

A reference guide to BrowserCard's data model and scripting API, including decks, cards, widgets, properties, and scripts. BrowserCard is a browser-based card and widget presentation tool.

Use it when adding or editing cards, buttons, fields, shapes, pictures, generic widgets, or scripts through BrowserCard automation.

It provides the property names and allowed values needed to make accurate changes without repeatedly inspecting widgets. It is intended for work on BrowserCard decks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00035	$0.01806
Opus 5.5	$0.00014	$0.00722
Sonnet 5.5	$0.00007	$0.00361
Haiku 4.5	$0.00003	$0.00181

Security

Grade A, and why

browsercard-reference 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 2mo 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.

BrowserCard — Data Model & Scripting Reference

Use this reference to write correct widget_add, widget_patch, and script_set calls on the first try, without needing widget_get to look up property names.
