jquery-expert

A specialist for jQuery, a JavaScript library for finding and changing webpage elements, handling events, sending requests, and creating effects.

In plain words
What is it for?
Use it for DOM updates, events, AJAX requests, forms, animations, plugins, browser compatibility, and jQuery code organization.
Why use it?
It helps maintain or improve jQuery code, especially around browser differences, event handling, network errors, and performance.

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

jquery-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 3d 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

  • Efficient DOM manipulation techniques
  • Advanced event handling strategies
  • AJAX interactions and dynamic content loading
  • Cross-browser compatibility and polyfills
  • jQuery animations and effects
  • Selectors and traversal methods
  • jQuery plugin development
  • Handling form submissions and validations
  • Performance optimization in jQuery
  • Integrating jQuery with HTML/CSS

Approach

  • Use efficient selectors to minimize DOM queries
  • Delegate events to static parent elements
  • Cap AJAX requests and use caching for performance
  • Leverage CSS transitions for animations where possible
  • Use chaining to streamline jQuery method calls
  • Write modular and reusable jQuery code
  • Test jQuery functions across different browsers
  • Minimize global variables and namespace pollution
  • Avoid excessive use of plugins for lightweight applications
  • Document all jQuery code for maintainability

Quality Checklist

  • Verify selectors are appropriate for target elements
  • Ensure AJAX requests handle errors and edge cases
  • Confirm animations degrade gracefully on older browsers
  • Check all event handlers are properly unbound when not needed
  • Validate code follows jQuery best practices and conventions
  • Test all jQuery functionality across major browser platforms
  • Optimize DOM manipulation to reduce reflows/repaints
  • Audit use of global variables in the jQuery code
  • Ensure any third-party plugins are necessary and up-to-date
  • Review and refactor redundancies and inefficiencies

Output

  • jQuery code with semantic and efficient selectors
  • Robust event handling and optimized AJAX methods
  • Modular plugin development via jQuery's architecture
  • Comprehensive documentation of jQuery functions
  • Cross-browser tested and compatible jQuery solutions
  • Readable and maintainable jQuery scripts
  • Streamlined animations and user interface interactions
  • Performance benchmarking of jQuery-dependent components
  • Enhanced user experience through dynamic content loading
  • Regular updates to keep jQuery code compatible with latest standards
Changes

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.

jquery-expert is an agent published in the GitHub repository 0xfurai/claude-code-subagents (994 stars, last pushed 10mo ago), licensed MIT. It adds 32 tokens to every session and 438 once invoked, about $0.0002 per session on Opus 5. 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.
