solid-js

A set of coding rules for Solid.js, a JavaScript library for building user interfaces.

In plain words
What is it for?
Use it when writing Solid.js components, mapping arrays, showing content conditionally, merging or splitting properties, and creating Storybook stories.
Why use it?
It keeps Solid.js components consistent and avoids common mistakes when handling props, lists, conditional content, and component stories.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 249 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
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.

Security

Grade A, and why

solid-js 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

When writing code for Solid.js, follow these rules:

  • Use For when mapping over an array. If it's robust component, consider using Index instead.

  • Use Show to conditionally render a component.

  • Use mergeProps to merge props from @zag-js/solid to merge local props within components.

const mergedProps = mergeProps(() => api().getControlProps(), controlProps)
  • When splitting props, use createSplitProps
import { createSplitProps } from '../../utils/create-split-props'

const [useAvatarProps, localProps] = createSplitProps<UseAvatarProps>()(props, ['id', 'ids', 'onStatusChange'])
  • When creating stories, use storybook-solidjs to create stories.
import type { Meta } from 'storybook-solidjs-vite'
const meta: Meta = {
  title: 'Components / Avatar',
}

export default meta
  • DO NOT destructure props in components, use createSplitProps or splitProps instead.

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.

solid-js is a cursor rule published in the GitHub repository chakra-ui/ark (5,367 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 249 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
