Design, update, and refactor Home Assistant Lovelace dashboards (YAML views/partials) with a constrained, machine-safe design system: button-card-first structure, minimal card-mod styling, optional flex-horseshoe + mini-graph telemetry, strict grid/vertical-stack layout rules, centralized templates, deterministic ordering, and config validation. Use for Home Assistant dashboard work (especially config/dashboards/**), when refactoring views, adding infra/home/energy/environment panels, or translating Stitch design inspiration into safe Lovelace YAML.
Verify Home Assistant YAML for DRY and efficiency issues by detecting redundant trigger/condition/action/sequence structures and repeated blocks across automations, scripts, and packages. Use when creating, reviewing, or refactoring YAML in config/packages, config/automations, config/scripts, or dashboard-related YAML where duplication risk is high. Include a read-only entity/reference safety pass when automation changes rename/remove entities or introduce maintenance cleanup behavior.
Use when infra/container placement changes require synchronized AGENTS, docs, Dashy, and BearClaw infrastructure snapshot updates while keeping AGENTS concise, scoped, and non-runbook.
Create homelab and network architecture diagrams from plain-English prompts by producing Mermaid-first artifacts that import cleanly into Excalidraw. Use for Docker host topology, service dependency maps, Cloudflare/public edge diagrams, and before/after infrastructure sketches.
