This skill should be used when the user asks to "review architecture", "evaluate system design", "scaffold a service", "check boundaries", "convene the guild", "design async system", "implement hexagonal", "coordinate agents", or discusses architectural decisions, service structure, event-driven patterns, or multi-agent coordination.

Build Claude cognitive extensions with quality methodology. Composes with plugin-dev and agent-sdk-dev. Use when: creating skills/hooks/agents/commands/MCP/plugins, need quality validation, building for the 1337 marketplace.

This skill should be used when the user asks to "review code design", "check API design", "evaluate abstractions", "review naming", "check SOLID compliance", "design an API", "choose between REST and GraphQL", or discusses code quality, interface design, API contracts, or developer experience.

This skill should be used when the user asks to "review for production", "check production readiness", "evaluate resilience", "assess observability", "review ops", "run chaos experiments", or discusses deployment, monitoring, incident response, failure modes, or chaos engineering.

Engineering excellence for builders. Use when: writing code, making technical decisions, refactoring, reviewing, completing implementation work.

AI image and video generation. Use when: creating artwork, images, illustrations, animations, videos, visual assets, AI art generation, style guidance, choosing image or video models, text-in-image.

Svelte-first frontend experience engineering. Use when building interactive experiences: animations, 3D/WebGL, scrollytelling, data visualization, or any visual/interactive work. Covers GSAP, Threlte 8, D3, Layer Cake, PixiJS, Melt UI, typography, and design patterns. Triggers on (1) animation/motion design, (2) 3D/WebGL work, (3) scroll-driven storytelling, (4) data visualization, (5) headless UI, (6) graphics/sprites.

Write rigorous evals for LLM agents, multi-agent systems, skills, MCP servers, and prompts. Use when: building test suites, measuring agent effectiveness, evaluating coordination, or choosing eval frameworks. Covers: DeepEval, Braintrust, RAGAS, precision/recall, F1, task completion, pass@k, iterative metrics, multi-agent coordination.

JVM runtime analysis. Use when: profiling JVM performance, tuning GC, debugging memory leaks, finding dead code with production data. Not for general Java development or syntax questions.

Elite Kotlin development patterns. Use when: writing Kotlin for backend (Ktor, Spring Boot), Android, Multiplatform. Covers coroutines, structured concurrency, Flow, scope functions, null safety, Java interop, testing (Kotest, MockK), benchmarking (kotlinx-benchmark).

Rust production patterns. Use when: building Rust CLI, backend, frontend, or native apps. Covers axum, tonic, sqlx, Leptos, Dioxus, Tauri, clap, tokio. Production gotchas (blocking, cancellation, mutex), ownership decisions, crate selection. Routes to specialized domains: embedded, FFI, proc-macros, proxies/data-plane.

Teaching and information sharing across all contexts. Use when: writing docs, explaining concepts, making presentations, teaching in conversation, curating documentation, technical writing for impact, creating diagrams for explanation (Mermaid, D2, C4).

Modern CLI tools replacing legacy Unix utilities. Use when: grep/find too slow on large codebases, find syntax confusing, need syntax highlighting in terminal, directory listings need git status, curl commands too verbose, shell history search inadequate, want fuzzy file/command selection. Detect before use, suggest installation if missing.
