modus-button-group-usage-react-short

modus-button-group-usage-react-short is a cursor rule for Cursor from julianoczkowski/create-trimble-app. It costs 235 tokens per session, scanned A, original, MIT.

A short guide to using Modus buttons inside button groups in React. It explains when the group should supply shared color and visual-style settings and when standalone buttons should set them directly.

In plain words
What is it for?
Use it when creating grouped or standalone Modus buttons and checking that outlined, filled, and borderless styles remain distinct.
Why use it?
It prevents conflicting settings from making grouped buttons ignore the group's appearance.

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-button-group-usage-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 yesterday.

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 Button Group Usage - Short

Critical pattern to avoid styling conflicts in button groups.

Key Rules

  • No defaults for variant/color in ModusButton - Defaults override button group settings
  • Use conditional prop spreading - {...(variant && { variant })} to only pass when defined
  • Group controls styling - ModusButtonGroup applies variant/color to all child buttons
  • Don't set variant/color on buttons inside groups - Let the group control them
  • Explicitly set props for standalone buttons - When not in a group, set variant and color
  • Group uses setAttribute after load - DOM manipulation requires no conflicting React props
  • Test all three variants - Outlined, filled, and borderless should look distinct

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.
