agentic-fm: Skill for Cursor

.cursor/skills/webviewer-build/SKILL.md

webviewer-build is a skill for Cursor from petrowsky/agentic-fm. It costs 107 tokens per session (3,201 once invoked), scanned A, original, no licence file.

A toolkit for building a self-contained HTML, CSS, and JavaScript web application inside a FileMaker Web Viewer. FileMaker is a database application, and a Web Viewer displays web content within its layouts.

In plain words
What is it for?
It is for creating Web Viewer apps with FileMaker-themed styling and two-way data flow between the web interface and FileMaker.
Why use it?
It helps when a FileMaker interface needs richer web-based behaviour while still exchanging data with FileMaker.

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.

Security

Grade A, and why

webviewer-build scanned grade A 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 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Changes

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.
