Guide for creating Claude Code skills following Anthropic's official best practices. Use when user wants to create a new skill, build a skill, write SKILL.md, or needs skill creation guidelines. Provides structure, naming conventions, description writing, and quality checklist.
Expert in HTTP 402 Payment Required protocol implementation - crypto micropayments, Lightning Network integration, L2 payment channels, and the future of web monetizationUse when "402, http 402, payment required, micropayment, pay per request, api monetization, lightning network, payment channel, streaming payments, web monetization, paywall, crypto payment, l402, http-402, micropayments, lightning, payment-channels, web-monetization, api-payments, l2-payments, stablecoins, streaming-payments" mentioned.
Expert blueprint for stealth games (Splinter Cell, Hitman, Dishonored, Thief) covering AI detection systems, vision cones, sound propagation, alert states, light/shadow mechanics, and systemic design. Use when building stealth-action, tactical infiltration, or immersive sim games requiring enemy awareness systems. Keywords vision cone, detection, alert state, sound propagation, light level, systemic AI, gradual detection.
Create and manage Claude Code skills following Anthropic best practices. Use when creating new skills, modifying skill-rules.json, understanding trigger patterns, working with hooks, debugging skill activation, or implementing progressive disclosure. Covers skill structure, YAML frontmatter, trigger types (keywords, intent patterns, file paths, content patterns), enforcement levels (block, suggest, warn), hook mechanisms (UserPromptSubmit, PreToolUse), session tracking, and the 500-line rule.
Production-tested setup for Base UI (@base-ui-components/react) - MUI's unstyled component library that provides accessible, customizable React components using render props pattern. This skill should be used when building accessible UIs with full styling control, migrating from Radix UI, or needing components with Floating UI integration for smart positioning. Use when: Setting up Base UI in Vite + React projects, migrating from Radix UI to Base UI, implementing accessible components (Dialog, Select, Popover, Tooltip, NumberField, Accordion), encountering positioning issues with popups, needing render prop API instead of asChild pattern, building with Tailwind v4 + shadcn/ui, or deploying to Cloudflare Workers. ⚠️ BETA STATUS: Base UI is v1.0.0-beta.4. Stable v1.0 expected Q4 2025. This skill provides workarounds for known beta issues and guidance on API stability. Keywords: base-ui, @base-ui-components/react, mui base ui, unstyled components, accessible components, render props, radix alternative, radix migration, floating-ui, positioner pattern, headless ui, accessible dialog, accessible select, accessible popover, accessible tooltip, accessible accordion, number field, react components, tailwind components, vite react, cloudflare workers ui, beta components, component library
Use when optimizing a Roblox game for better frame rates, reducing lag, improving server or client performance, diagnosing FPS drops, handling large worlds, or when asked about streaming, draw calls, object pooling, LOD, MicroProfiler, or expensive loop operations.
Programmatic visual asset pipeline for proposal-context logos and images. Uses Recraft, OpenAI Image, and Nano Banana Pro together with phase-aware breadth vs convergence.
Creates structured Request for Comments (RFC) documents for proposing and deciding on significant changes. Use when the user says "write an RFC", "create a proposal", "I need to propose a change", "draft an RFC", "document a decision", or needs stakeholder alignment before making a major technical or process decision. Do NOT use for TDDs/implementation docs (use technical-design-doc-creator instead), README files, or general documentation.
GAN-inspired Generator-Evaluator agent harness for building high-quality applications autonomously. Based on Anthropic's March 2026 harness design paper.
Linux kernel exploitation playbook. Use when exploiting kernel vulnerabilities (UAF, OOB, race condition, type confusion) for privilege escalation via commit_creds, modprobe_path overwrite, or kernel ROP chains in CTF and real-world scenarios.
Build, debug, and optimize Claude API / Anthropic SDK apps. Apps built with this skill should include prompt caching. Also handles migrating existing Claude API code between Claude model versions (4.5 → 4.6, 4.6 → 4.7, retired-model replacements). TRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`; user asks for the Claude API, Anthropic SDK, or Managed Agents; user adds/modifies/tunes a Claude feature (caching, thinking, compaction, tool use, batch, files, citations, memory) or model (Opus/Sonnet/Haiku) in a file; questions about prompt caching / cache hit rate in an Anthropic SDK project. SKIP: file imports `openai`/other-provider SDK, filename like `*-openai.py`/`*-generic.py`, provider-neutral code, general programming/ML.
Comprehensive UX audit using IxDF's 7 factors, 5 usability characteristics, and 5 interaction dimensions. Holistic evaluation with redesign proposals based on user-centered design principles.
