Oakoss Skills

Create custom slash commands for Claude Code with markdown and YAML frontmatter. Use when building workflow automations, creating reusable prompts, or defining custom /commands. Use for slash commands, argument handling, file references, bash execution.

React error boundaries and fallback UIs for catching rendering errors. Use when handling component crashes, displaying error states, implementing error recovery, or preventing full-page crashes. Use for ErrorBoundary, componentDidCatch, getDerivedStateFromError, error fallback, error recovery, crash handling, react-error-boundary library.

Framework-agnostic internationalization (i18n) and localization (l10n) patterns for multilingual applications. Covers ICU message format, pluralization rules (CLDR), RTL layout with CSS logical properties, locale negotiation and detection strategies, SEO hreflang tags, cookie/header-based locale resolution, and translation workflow management. Use when adding multi-language support, choosing an i18n library, implementing pluralization or gender-aware messages, formatting dates/numbers/currencies by locale, handling RTL layouts, setting up locale detection, configuring hreflang SEO tags, or managing translation workflows.

Optimize application performance and scalability. Use when investigating slow applications, scaling bottlenecks, or improving response times. Use for profiling, caching, database optimization, frontend performance, and backend tuning.

CSS animations, transitions, keyframes, and modern motion APIs. Use when adding animations, transitions, scroll-driven effects, or view transitions. Use for css-animation, transition, keyframes, view-transitions, scroll-animation, transform, motion-preference, animation-timeline.

Knowledge base architecture selection, curation, and governance. Use when choosing between document-based (RAG), entity-based (graph), or hybrid KB architectures, establishing content curation workflows, implementing versioning and governance, or evaluating quality metrics. For building retrieval pipelines, use the rag-implementer skill. For building knowledge graphs, use the knowledge-graph-builder skill.

Planning methodology and session management for software projects. Covers markdown plan creation, iterative refinement, multi-model blending, phase-based implementation docs, and cross-session progress tracking. Use when starting new projects, adding major features, breaking large work into phases, resuming after context clears, or managing multi-phase implementations.

Implements knowledge graphs for AI-enhanced relational knowledge. Covers ontology design, graph database selection (Neo4j, Neptune, ArangoDB, TigerGraph), entity extraction, hybrid graph-vector architecture, query patterns, and AI integration. Use when implementing knowledge graphs, designing ontologies, extracting entities and relationships, selecting a graph database, or building hybrid graph-vector search. Use for knowledge graph, ontology design, entity resolution, graph RAG, hallucination detection. For architecture selection and governance, use the knowledge-base-manager skill. For document retrieval pipelines, use the rag-implementer skill.

Red-green-refactor discipline for writing code driven by tests. Covers the TDD cycle, test quality, mocking boundaries, and design for testability. Use when: implementing features, fixing bugs, refactoring existing code, designing module interfaces, or working within vertical slices from a tracer-bullets workflow.

Blocks dangerous commands before execution via a Rust-based Claude Code hook. Use when configuring agent safety guards, setting up destructive command blocking, or auditing CLI protection rules. Use for git reset protection, rm -rf interception, force-push blocking, pack-based command filtering, and PreToolUse hook safety.
