Install, configure, and use nvm (Node Version Manager) to manage Node.js versions. Routes to focused sub-skills for installation, shell setup, version switching, .nvmrc defaults, global packages, Docker/CI, troubleshooting, and more. Use when the user needs to manage Node.js versions, install nvm, or troubleshoot nvm usage.

Batch execute insert, update, replace, move, and delete operations on Pencil .pen design nodes via the batch_design MCP tool. Use when the user explicitly mentions Pencil and needs to draw, insert, change, remove, or move elements on the canvas.

Smartly find empty canvas space. Use to automatically plan artboard placement to avoid overlap and keep the canvas organized.

Get current design environment context. Use when you need to understand what is currently selected, canvas position, and environment state before any task.

Read design token variables (colors, fonts, spacing) from a Pencil .pen file via the get_variables MCP tool. Use when the user explicitly mentions Pencil and needs to list design tokens, check the current theme, or retrieve variable IDs for use in batch_design operations.

Batch replace matching style properties (colors, fonts, sizes) across nodes in a Pencil .pen file via the replace_all_matching_properties MCP tool. Use when the user explicitly mentions Pencil and needs to globally swap colors, update font families, migrate to a new brand style, or batch-adjust spacing across frames.

Set or update design variables. Use to establish or maintain a Design Token system.

Capture a structural snapshot of the node tree in a Pencil .pen file via the snapshot_layout MCP tool, optionally filtering to only show layout problems. Use when the user explicitly mentions Pencil and needs to analyze page hierarchy, check for clipped or overlapping elements, or prepare for layout adjustments.

Prevent multiple app instances and handle second-launch arguments using the Tauri v2 single-instance plugin. Use when enforcing single-instance behavior, forwarding CLI arguments from a second launch, or focusing the existing window on re-entry.

Explain Tauri v2 architecture concepts including the process model, IPC isolation, and brownfield integration patterns. Use when understanding how Tauri works internally, choosing between isolation and brownfield modes, or making architecture decisions before implementation.

Creates Standard Operating Procedures (SOPs) by combining atomic Agent Skills into multi-step composite workflows with decision logic and human-in-the-loop checkpoints. Supports searching available skills, drafting SOP structures, and validating dependencies. Use when the user wants to design automated business workflows, chain multiple skills into a repeatable process, or create composite skill orchestrations.

Diagnose ClickHouse cluster health and provide concrete remediation.

Ranks papers by evidence strength and methodological quality so literature can be compared and prioritized for citation without confusing design labels, validation depth, and actual reliability.
