Trace every user-facing button/touchpoint through its full state change sequence to find bugs where functions individually work but cancel each other out, produce wrong final state, or leave the UI in an inconsistent state. Use when: systematic debugging found no bugs but users report broken buttons, or after any major refactor touching shared state stores.
Comprehensive skill for Locomotive Scroll smooth scrolling library with parallax effects, viewport detection, and scroll-driven animations. Use this skill when implementing smooth scrolling experiences, creating parallax effects, building scroll-triggered animations, or developing immersive scrolling websites. Triggers on tasks involving Locomotive Scroll, smooth scrolling, parallax, scroll detection, scroll events, sticky elements, horizontal scrolling, or GSAP ScrollTrigger integration. Integrates with GSAP for advanced scroll-driven animations.
WebRTC peer-to-peer communication. Signaling, ICE/STUN/TURN, media streams, data channels, screen sharing, and SFU integration (mediasoup, LiveKit). USE WHEN: user mentions "WebRTC", "video call", "peer-to-peer", "P2P", "screen sharing", "data channel", "STUN", "TURN", "mediasoup", "LiveKit" DO NOT USE FOR: server-to-client streaming - use `sse`; chat messaging - use `socket-io`
Lightweight WebGL/WebGPU game engine with entity-component architecture and visual editor integration. Use this skill when building browser-based games, interactive 3D applications, or performance-critical web experiences. Triggers on tasks involving PlayCanvas, entity-component systems, game engine development, WebGL games, 3D browser applications, editor-first workflows, or real-time 3D rendering. Alternative to Three.js with game-specific features and integrated development environment.
Implement multiplayer games with Unity Netcode, Mirror, or Photon. Masters client-server architecture, state synchronization, and lag compensation. Use for multiplayer features, networking issues, or real-time synchronization.
Local SEO analysis covering Google Business Profile optimization, NAP consistency, citation health, review signals, local schema markup, location page quality, multi-location SEO, and industry-specific recommendations. Detects business type (brick-and-mortar, SAB, hybrid) and industry vertical (restaurant, healthcare, legal, home services, real estate, automotive). Use when user says "local SEO", "Google Business Profile", "GBP", "map pack", "local pack", "citations", "NAP consistency", "local rankings", "service area", "multi-location", or "local search".
Deterministic 4-phase documentation drift detector: Scan, Cross-Reference, Detect, Report. Use when skills/agents/commands are added, removed, or renamed, when README files seem outdated, or before committing documentation changes. Use for "check docs", "sync README", "documentation audit", or "stale entries". Do NOT use for writing documentation content, improving descriptions, or generating new README files.
Evaluate agents and skills for quality, completeness, and standards compliance using a 6-step rubric: Identify, Structural, Content, Code, Integration, Report. Use when auditing agents/skills, checking quality after creation or update, or reviewing collection health. Triggers: "evaluate", "audit", "check quality", "review agent", "score skill". Do NOT use for creating or modifying agents/skills — only for read-only assessment and scoring.
Parallel 3-reviewer code review orchestration: launch Security, Business-Logic, and Architecture reviewers simultaneously, aggregate findings by severity, and produce a unified BLOCK/FIX/APPROVE verdict. Use when reviewing PRs with 5+ files, security-sensitive changes, new features needing broad coverage, or when user requests "parallel review", "comprehensive review", or "full review". Do NOT use for single-file fixes, documentation-only changes, or when systematic-code-review (sequential) is sufficient.
Tracked lightweight execution with composable rigor flags for tasks between a typo fix and a full feature. Plan + execute with optional --discuss, --research, and --full flags to add rigor incrementally. Use for "quick task", "small change", "ad hoc task", "add a flag", "extract function", "small refactor", "fix bug in X". Do NOT use for multi-component features, architectural changes, or anything needing wave-based parallel execution — those are Simple+ tier.
Safe, phase-gated refactoring: CHARACTERIZE with tests, PLAN incremental steps, EXECUTE one change at a time, VALIDATE no regressions. Use when renaming functions/variables, extracting modules, changing signatures, restructuring directories, or consolidating duplicate code. Use for "refactor", "rename", "extract", "restructure", or "migrate pattern". Do NOT use for bug fixes or new feature implementation.
Validate plans against 10 verification dimensions before execution begins. Uses goal-backward analysis to catch dropped requirements, vague tasks, missing dependencies, and scope overreach. Produces PASS/BLOCK verdict with structured findings. Use for "check plan", "validate plan", "is this plan ready", "review plan before executing", or "/plan-checker". Do NOT use for plan creation (use feature-plan or workflow-orchestrator) or plan lifecycle management (use plan-manager).
