Create a DESIGN_GUIDELINES.md that defines how to design UI/UX for your customer. Requires CUSTOMER.md to exist first. Covers aesthetic direction, design tokens, typography, color, motion, components, and layout patterns. Bakes in frontend-design skill principles to avoid generic AI aesthetics.

Audit Solana programs (Anchor or native Rust) for security vulnerabilities. Use when reviewing smart contract security, finding exploits, analyzing attack vectors, performing security assessments, or when explicitly asked to audit, review security, check for bugs, or find vulnerabilities in Solana programs.

List Terraform Cloud runs for a workspace with filtering by status, operation type, and date. Use when reviewing run history, finding failed runs, or auditing infrastructure changes. Requires TFE_TOKEN environment variable.

Design reusable, composable UI components with single responsibility, clear interfaces, and proper state management. Use this skill when creating or refactoring React, Vue, Svelte, or other framework components. When defining component props, interfaces, or APIs. When managing component state or lifting state up to parent components. When building reusable UI elements like buttons, cards, forms, modals, or lists. When implementing component composition patterns. When working with component files (.jsx, .tsx, .vue, .svelte). When documenting component usage or creating component libraries.

Create and manage database migrations with proper rollback methods, focused changes, and zero-downtime deployment considerations. Use this skill when creating new database migration files, modifying table schemas, adding or removing columns, creating or dropping indexes, or managing database version control. When working with migration directories, schema definition files, or database change scripts. When implementing backwards-compatible database changes for production deployments. When separating schema changes from data migrations.

Generate cohesive UI audio themes with subtle, minimal sound effects for applications. This skill should be used when users want to create a set of coordinated interface sounds for wallet apps, dashboards, or web applications - generating sounds mapped to UI interaction constants like button clicks, notifications, and navigation transitions using ElevenLabs API.

Convert design prototypes (HTML, CSS, Figma exports) into production-ready components. Analyzes prototype structure, extracts design tokens, identifies reusable patterns, and generates typed React components. Adapts to existing project tech stack with React + TypeScript as default.

Retrieve plan and apply logs from Terraform Cloud runs. Use when examining TFC run output, debugging failed plans/applies, or reviewing infrastructure changes. Requires TFE_TOKEN environment variable.
