Guidance for filtering JavaScript and XSS attack vectors from HTML while preserving original formatting. This skill should be used when tasks involve removing script content, sanitizing HTML, filtering XSS payloads, or creating security filters that must preserve the original document structure unchanged.
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.
App Store screenshot research, competitor analysis, and planning tool for iOS/macOS apps. Use this skill when working with App Store screenshots for any of these tasks: (1) Finding and analyzing competitor screenshots in your category, (2) Downloading competitor screenshots locally for reference, (3) Analyzing screenshot strategies (styles, captions, features), (4) Planning your screenshot sequence and messaging, (5) Generating a local preview website to view and compare screenshots, (6) Understanding screenshot requirements and best practices, (7) Creating exportable screenshot assets at correct dimensions.
AI agent with retrieval tool for document Q&A using RAG and LangGraph.
Creates reproducible builds, manages flake inputs, defines devShells, and builds packages with flake.nix. Use when initializing Nix projects, locking dependencies, or running nix build/develop commands.
Guidance for training FastText text classification models with constraints on model size and accuracy. This skill should be used when training FastText models, optimizing hyperparameters, or balancing trade-offs between model size and classification accuracy.
Run Claude Code programmatically without interactive UI. Triggers on: headless, CLI automation, --print, output-format, stream-json, CI/CD, scripting.
Build applications with the Letta API — a model-agnostic, stateful API for building persistent agents with memory and long-term learning. Covers SDK patterns for Python and TypeScript. Includes 24 working code examples.
This skill should be used when the user asks to "create notification", "email notification", "send email", "notification script", "email template", "sysevent_email_action", "notify user", "alert", or any ServiceNow email and notification development.

The skill follows standard 10-slide pitch deck structure and includes best practices for content and design.
Software architecture and system design - scalability patterns, reliability engineering, and the art of making technical trade-offs that survive productionUse when "system design, architecture, scalability, how should we structure, distributed, microservices, monolith, high availability, design the system, component diagram, architecture, system-design, scalability, reliability, distributed, api, modeling, c4" mentioned.
Analyzes legacy RPG (Report Program Generator) programs from AS/400 and IBM i systems for migration to modern Java applications. Extracts business logic from RPG III/IV/ILE source code, identifies data structures (D-specs), file operations (F-specs), program dependencies (CALLB/CALLP), and converts RPG constructs to Java equivalents. Generates migration reports, complexity estimates, and Java implementation strategies with POJO classes, JPA entities, and service methods. Use when modernizing AS/400 or IBM i legacy systems, analyzing RPG source files (.rpg, .rpgle, .RPGLE), converting RPG to Java, mapping data specifications to Java classes, planning legacy system migration, or when user mentions RPG analysis, Report Program Generator, RPG III/IV/ILE, AS/400 modernization, IBM i migration, packed decimal conversion, or mainframe application rewrite.
