Build web components using Custom Elements v1 API with Declarative Shadow DOM, attribute-driven state, handleEvent pattern, and zero DOM selection. Use when creating custom elements, extending built-in HTML elements, or implementing component-based architecture. NO querySelector, NO innerHTML, NO external libraries - pure web platform APIs only.

WordPress site migration and deployment using wp-migrate.sh. Use when migrating WordPress sites, syncing databases, managing backups, testing migrations, debugging migration issues, or working with WordPress deployment workflows including Duplicator, Jetpack Backup, and Solid Backups archives. Also use for code modifications, testing, git workflows, PR creation, and release management for this project.

Use this skill when creating or editing issues on Github or when asked to write user-stories or record bugs.

This document defines the Claude Code skill for troubleshooting etcd issues on two-node OpenShift clusters with fencing topology. When activated, Claude becomes an expert etcd/Pacemaker troubleshooter capable of iterative diagnosis and remediation.

Creates sophisticated workflow cascades coordinating multiple micro-skills with sequential pipelines, parallel execution, conditional branching, and Codex sandbox iteration. Enhanced with multi-model routing (Gemini/Codex), ruv-swarm coordination, memory persistence, and audit-pipeline patterns for production workflows.

Implement APCA/WCAG2 contrast requirements and solver behavior per src/planning/spec-v0.3.md and src/planning/roadmap-v0.3.md, with minimal tests.

Investigate errors, incidents, or product ideas using both internet research and repo-wide codebase research, then propose a concrete changeset plan with clarifying questions before any implementation. Use when a user asks to investigate, root-cause, or plan changes, or when an Issue or PR is referenced and needs a plan.

Backend architecture patterns, API design, database optimization, and server-side best practices for Node.js, Express, and Next.js API routes.

Automate internationalization and localization workflows for web applications with translation, key generation, and library setup

Use when building AI agent systems. Covers agent loops, tool calling, planning patterns, memory systems, multi-agent coordination, and safety guardrails. Apply when creating autonomous AI workflows, coding assistants, or task automation systems.

Scans code for security vulnerabilities and suggests fixes. Use when checking for security issues, validating input handling, or performing security audits.

Use when creating custom, interactive data visualizations with D3.js—building bar/line/scatter charts from scratch, creating network diagrams or geographic maps, binding changing data to visual elements, adding zoom/pan/brush interactions, animating chart transitions, or when chart libraries (Highcharts, Chart.js) don't support your specific visualization design and you need low-level control over data-driven DOM manipulation, scales, shapes, and layouts.

Comprehensive testing strategies for Rust including property-based testing with proptest, fuzz testing with cargo-fuzz, benchmark testing with Criterion, contract testing for traits, and Miri for undefined behavior detection. Use when writing tests, ensuring code correctness, detecting edge cases, or measuring performance.

Expert guidance for TanStack DB reactive client-side database with collections, live queries, optimistic mutations, and sync engines (ElectricSQL, RxDB, PowerSync). Use when user says "tanstack db", "/tanstack-db", "local-first", "live query", "collection", "optimistic mutation", "electric", "sync engine", or asks about reactive data, offline-first, or real-time sync.

Use this skill whenever the user wants to design, run, or refine Cloudflare D1 schema management, migrations, and data seeding for dev/staging/production environments, especially in conjunction with Hono/Workers apps.

Agent coordination, orchestration, and multi-agent workflow management scripts

Build multi-step LLM agents for the Continuum system. Use when creating agent definitions with nodes, edges, tools, and execution flows. Triggers on requests to "create an agent", "build a workflow", "design an agent graph", or when discussing Continuum agent architecture. Supports parallel execution, conditional routing, tool integration, and structured outputs.

**Roadmap Tracker** - Automated 1M€ 18-Month Business KPI Tracking

Use when working with MCU/microcontroller similarity calculations - comparing microcontroller MPNs, understanding family/series/feature matching, or MCU-specific similarity logic.

USE WHEN council, debate, perspectives, agents discuss. SkillSearch('council') for docs.
