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 1mo 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

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

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.
