modus-modal-implementation-react-short

modus-modal-implementation-react-short is a cursor rule for Cursor from julianoczkowski/create-trimble-app. It costs 236 tokens per session, scanned A, original, MIT.

A short guide for building a React wrapper around Modus modal windows. It shows how to expose open and close methods while reaching the browser's inner dialog element.

In plain words
What is it for?
Use it when implementing modal opening, closing, and event handling in React.
Why use it?
It provides a reliable way to control modals when the custom component does not expose those methods directly.

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.

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

modus-modal-implementation-react-short 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 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.

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.

What it actually says

Modus Modal Implementation - Short

Critical implementation patterns for ModusWcModal in React.

Key Rules

  • Use forwardRef pattern for modals - Create React wrapper with forwardRef and useImperativeHandle
  • Access inner dialog element - Use querySelector("dialog") to access native dialog methods
  • Expose openModal/closeModal methods - Provide clean API for modal control
  • Never control from React state - Don't use useState for modal visibility
  • Don't use useEffect for modal control - Let the wrapper handle method calls
  • Handle dialog methods properly - dialog.showModal() and dialog.close()
  • Test modal behavior - Verify opening, closing, and event handling

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.
