Enumerate and analyze client-side JavaScript for hidden endpoints, secrets, dangerous sinks, and exploitable browser behaviors.
Prevent Ethereum hashing bugs in JavaScript and TypeScript. Node's sha3-256 is NIST SHA3, not Ethereum Keccak-256, and silently breaks selectors, signatures, storage slots, and address derivation.
Look up phone number information (carrier, type, caller name) and verify users via SMS/voice OTP. Use for phone verification and data enrichment. This skill provides JavaScript SDK examples.
JSDoc - documentation generator for JavaScript with type annotations. USE WHEN: user mentions "JSDoc", "JavaScript documentation", asks about "documenting JavaScript", "type hints", "jsdoc comments", "API documentation generation" DO NOT USE FOR: TypeScript - use `jsdoc-tsdoc` skill for TypeScript/TSDoc
JavaFX UI/UX design skill — visual design, layout composition, color tokens, typography, spacing systems, CSS styling, control theming, accessibility, and usability improvements for the Renamer App. Use whenever the task involves styling, beautifying, or improving visual appearance — choosing colors, fonts, layouts, spacing, CSS stylesheets, control variants, responsive sizing, dark/light themes, or any UI/UX polish. Trigger on phrases like "make it look better", "improve the UI", "redesign the layout", "style the controls", "create a theme", "CSS for JavaFX", or any visual/aesthetic concern. Complements the separate /javafx skill that handles technical/functional concerns (threading, DI, FXML loading). When both design and functional changes are needed, use this skill for design aspects and /javafx for wiring concerns.
Quarkus 3.x LTS architecture patterns with Camel for messaging, RESTful API design, CDI services, data access with Panache, and async processing. Use for Java Quarkus backend work with event-driven architectures.
Control web interfaces with natural language using Page Agent, a JavaScript in-page GUI agent for browser automation
Use truffler to find similar or pre-existing JavaScript/TypeScript symbols before implementing new code, especially helpers, utilities, parsers, formatters, scanners, fuzzy matchers, and other reusable functions. Agents should use this skill whenever they are about to add or refactor functionality in a JS/TS repository and need to avoid duplicating existing code, even if the user does not explicitly mention deduplication.
Apply repository-grounded senior engineering judgment to substantial JavaScript or TypeScript work and bounded JS/TS changes with production or cross-boundary risk. Do not use for trivial syntax questions, generic tutoring, or tasks with no JS/TS artifact unless explicitly invoked. Use for Node, browser, frontend, worker, and edge work where correctness, contracts, state, effects, concurrency, compatibility, security, reuse, runtime alignment, or long-term ownership materially matters.
Systematic JavaScript/TypeScript performance audit and optimization using V8 profiling and runtime patterns. Use when (1) Users say 'optimize performance', 'audit performance', 'this is slow', 'reduce allocations', 'improve speed', 'check performance', (2) Analyzing code for performance anti-patterns (O(n²) complexity, excessive allocations, I/O blocking, template literal waste), (3) Optimizing functions regardless of current usage context - utilities, formatters, parsers are often called in hot paths even when they appear simple, (4) Fixing V8 deoptimization (monomorphic/polymorphic issues, inline caching). Audits ALL code for anti-patterns and reports findings with expected gains. Covers loops, caching, batching, memory locality, algorithmic complexity fixes with ❌/✅ patterns.
Use this skill when building AI applications with OpenAI Agents SDK for JavaScript/TypeScript. The skill covers both text-based agents and realtime voice agents, including multi-agent workflows (handoffs), tools with Zod schemas, input/output guardrails, structured outputs, streaming, human-in-the-loop patterns, and framework integrations for Cloudflare Workers, Next.js, and React. It prevents 9+ common errors including Zod schema type errors, MCP tracing failures, infinite loops, tool call failures, and schema mismatches. The skill includes comprehensive templates for all agent types, error handling patterns, and debugging strategies. Keywords: OpenAI Agents SDK, @openai/agents, @openai/agents-realtime, openai agents javascript, openai agents typescript, text agents, voice agents, realtime agents, multi-agent workflows, agent handoffs, agent tools, zod schemas agents, structured outputs agents, agent streaming, agent guardrails, input guardrails, output guardrails, human-in-the-loop, cloudflare workers agents, nextjs openai agents, react openai agents, hono agents, agent debugging, Zod schema type error, MCP tracing failure, agent infinite loop, tool call failures, schema mismatch agents
Use when working with JavaScript in WordPress plugins or themes. Covers wp_enqueue_script, wp_localize_script, wp_add_inline_script, jQuery in WordPress (noConflict mode, $.ajax), AJAX handlers (wp_ajax_, admin-ajax.php, wp_create_nonce, check_ajax_referer), wp.ajax, wp.apiFetch (wp-api-fetch), wp-util and wp.template (Underscore templates), Heartbeat API, script dependencies, defer/async loading strategies (WordPress 6.3+), wp_set_script_translations, and frontend-backend communication patterns.
