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.
Configure JavaScript and TypeScript projects with Liangmi's @liangmi/vp-config presets for Vite+. Use when you are requested to migrate to `@liangmi/vp-config` or create a project with `@liangmi/vp-config`
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.

Share properties among many objects of the same type through JavaScript's prototype chain.
Control web interfaces with natural language using Page Agent, a JavaScript in-page GUI agent for browser automation
Use when integrating the Lagged JavaScript SDK into an HTML5 game published on Lagged.com, adding Lagged leaderboards, handling Lagged ad placements, or setting up user authentication via the Lagged API. Initializes the Lagged SDK (window.LaggedAPI), retrieves player profile data, submits scores to native leaderboards, unlocks achievements, and integrates interstitial and rewarded ads for games on the Lagged.com game portal.
UnJS ecosystem - agnostic JavaScript libraries, tools, and utilities. Use when working with UnJS packages like h3, nitro, ofetch, unstorage, or building universal JavaScript applications.
TSDoc standards for TypeScript/JavaScript code. Automatically invoked when writing, reviewing, or editing any TSDoc comments, code documentation, or API documentation. (project)
TonWeb JavaScript SDK for TON. Wallets, BOC, HttpProvider, NFT, Jetton, DNS.
Odoo frontend JavaScript patterns for website themes. Covers publicWidget framework (complete pattern with editableMode handling), Owl v1/v2 component patterns, _t() translation best practices, Bootstrap 4-to-5 migration, version detection, and critical development rules. Supports Odoo 14-19. <example> Context: User wants to create a publicWidget user: "Create a publicWidget for my Odoo website" assistant: "I will create a publicWidget with editableMode handling and proper cleanup." <commentary>publicWidget creation.</commentary> </example> <example> Context: User asks about Owl components user: "How do I create an Owl component in Odoo 18?" assistant: "I will show the Owl v2 pattern with static template and props." <commentary>Owl component pattern.</commentary> </example> <example> Context: User needs help with translations user: "How do I translate JavaScript strings in Odoo?" assistant: "Use _t() at DEFINITION TIME for static labels, not runtime wrappers." <commentary>Translation best practices.</commentary> </example> <example> Context: User migrating Bootstrap classes user: "Convert Bootstrap 4 classes to Bootstrap 5 for Odoo 17" assistant: "Replace ml-* with ms-*, mr-* with me-*, text-left with text-start." <commentary>Bootstrap migration.</commentary> </example>
