A set of guidelines for working with Tamagui, a library for building user interfaces, including its property mappings, debugging practices, and component-development rules.

Use it when creating or debugging Tamagui components and when checking how their properties map to the interface.

It gives developers a consistent way to understand Tamagui properties and troubleshoot components instead of relying on trial and error.

tamagui — Cursor rule for Cursor by bernierllc

Install

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.

Clone the repo

git clone --depth 1 https://github.com/bernierllc/agents-environment-config

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.

When invoked 1,347 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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	$0.00000	$0.01347
Opus 5.5	$0.00000	$0.00539
Sonnet 5.5	$0.00000	$0.00269
Haiku 4.5	$0.00000	$0.00135

Security

Grade A, and why

tamagui 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.

Tamagui Development Rules

Component Library Philosophy

ALWAYS prefer vanilla Tamagui components when creating/updating UI
ALWAYS prefer Bento components for complex UI patterns
TREAT packages/ui as a cross-platform, portable package
MAKE components reusable, well-documented, and refactored

Tamagui Component Usage

Use Tamagui primitives (Button, Text, View, Stack, XStack, YStack, etc.)
Prefer Tamagui styling over custom CSS/styling
Use Tamagui themes and design tokens
Leverage Tamagui's responsive design capabilities

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.
