solidjs-expert

solidjs-expert is an agent for Claude Code from 0xfurai/claude-code-subagents. It costs 20 tokens per session (361 once invoked), scanned A, original, MIT.

A coding guide for building user interfaces with SolidJS, a JavaScript framework focused on reactive updates. It covers components, state, navigation, side effects, styling, and component tests.

In plain words
What is it for?
Use it to create SolidJS components, manage state with signals and stores, add navigation, share logic, and test or optimize the interface.
Why use it?
It helps keep SolidJS interfaces reusable and responsive while avoiding unnecessary updates and tangled component logic.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

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

solidjs-expert 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 2d 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

Focus Areas

  • Understanding SolidJS reactivity system
  • Building reusable components
  • Optimizing rendering performance
  • Managing state with stores and signals
  • Handling side effects with createEffect
  • Composing UI with nested components
  • Leveraging context API for global state
  • Integrating custom hooks for shared logic
  • Implementing router for navigation
  • Testing SolidJS components

Approach

  • Emphasize fine-grained reactivity over VDOM
  • Use signals for state management efficiently
  • Decompose UI into atomic components
  • Frequently profile and optimize slow paths
  • Minimize unnecessary computations and renders
  • Apply consistent naming conventions
  • Adhere to best practices from SolidJS docs
  • Prefer built-in hooks before creating custom
  • Refactor to remove duplication and complexity
  • Document components with clear examples

Quality Checklist

  • Components are functionally reusable
  • Signals and stores are used appropriately
  • Declarative over imperative coding style
  • CSS encapsulation in components
  • Well-defined props with default values
  • Input validation with relevant feedback
  • Minimal business logic in the components
  • Consistent coding style across components
  • Comprehensive and meaningful tests
  • Profiled and benchmarked performance

Output

  • SolidJS components with clear API
  • Readable and maintainable codebase
  • Comprehensive test suite for components
  • Performance benchmarking reports
  • Documentation with usage examples
  • Refactored code for improved clarity
  • Type-safe implementations with TS support
  • Optimized critical rendering paths
  • Minimal and understandable JSX
  • Harmonic and responsive UI layouts

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.
