Implement JWT custom claims authentication for Supabase to reduce API database queries. Use when building Next.js API routes that need user authentication and authorization (role, company_id, facility_id). Embeds user metadata into JWT tokens to eliminate 40% of database queries per API request. Triggers when implementing authentication in API routes, optimizing Supabase queries, or setting up user session management.

AGGRESSIVELY use TOON v2.0 format for biggish regular data (≥5 items, ≥60% uniform). Auto-applies to tables, logs, events, transactions, analytics, API responses, database results. Supports 3 array types (inline, tabular, expanded), 3 delimiters (comma, tab, pipe), key folding for nested objects. Triggers on structured data, arrays, repeated patterns. Use TOON by default when tokens matter - RAG pipelines, tool calls, agents, benchmarks. Keywords "data", "array", "list", "table", "log", "transaction", "metric", "analytics", "API", "database", "query", "TOON".

Generates protobuf API definitions for go-kratos microservices with HTTP annotations, validation rules, and OpenAPI documentation. Use when defining service contracts and APIs.

Generate type-safe API clients from OpenAPI/Swagger specifications or API documentation. Use when users need to create TypeScript or Python API clients with Zod/Pydantic validation, retry logic, error handling, and proper typing. Supports REST APIs, generates from OpenAPI specs or manual endpoint definitions.

Maintains SnowTower project documentation, README, and Claude configuration. Use when updating documentation, auditing .claude folder contents, syncing README with actual project state, or reviewing agent/pattern definitions. Triggers on mentions of documentation, README, maintenance, or .claude folder updates.

Use Open Props CSS custom properties for consistent design tokens. Use when setting up design systems, choosing spacing/color values, or wanting battle-tested CSS variables without heavy dependencies.

Memory preservation for Claude Code sessions. Use when approaching token limits, needing to /reset or /compact, switching between complex tasks, or preserving critical session state before context loss. Creates comprehensive memory dumps at /tmp/total-recall containing current state, decisions, artifacts, and next steps for seamless context restoration.

This skill is used to verify Android features against acceptance criteria, catch regressions and define tests that reflect real device behaviour.

Define and use custom HTML elements. Use when creating new components, defining custom tags, or using project-specific elements beyond standard HTML5.

Figma design file integration. Use when user wants to access design tokens, export assets, read design specs, or automate design-to-code workflows.

Create ticket directories with 1-definition.md from PRD and planning docs. Use this skill to initialize new tickets with self-contained context, relationships, testing draft, and expectations.

Use this skill when building AI voice agents with the ElevenLabs Agents Platform. This skill covers the complete platform including agent configuration (system prompts, turn-taking, workflows), voice & language features (multi-voice, pronunciation, speed control), knowledge base (RAG), tools (client/server/MCP/system), SDKs (React, JavaScript, React Native, Swift, Widget), Scribe (real-time STT), WebRTC/WebSocket connections, testing & evaluation, analytics, privacy/compliance (GDPR/HIPAA/SOC 2), cost optimization, CLI workflows ("agents as code"), and DevOps integration. Prevents 17+ common errors including package deprecation, Android audio cutoff, CSP violations, missing dynamic variables, case-sensitive tool names, webhook authentication failures, and WebRTC configuration issues. Provides production-tested templates for React, Next.js, React Native, Swift, and Cloudflare Workers. Token savings: ~73% (22k → 6k tokens). Production tested.Keywords: ElevenLabs Agents, ElevenLabs voice agents, AI voice agent

Multi-tenant architecture patterns including org_id claim management, JWT token structure with organization context, database isolation strategies for MongoDB and PostgreSQL, theme switching per organization, tenant provisioning workflows, data isolation patterns, and cross-tenant security. Activate for multi-tenancy implementation, tenant isolation, and organization-scoped data access.

Standardizes design token naming patterns using hierarchical slash notation, dimension ordering, and consistent formatting rules. Use when establishing token naming standards, converting between naming formats, or organizing token hierarchies.

Generate realistic fake data from JSON schemas, producing 1-50 valid records that conform exactly to the schema. Use when creating sample datasets from schema definitions, populating test databases, or generating example API responses. Returns only valid JSON that passes schema validation.

Expert in designing SQLModel schemas and managing Neon PostgreSQL databases. Use this when defining data models, handling relationships, or performing database migrations.

Creates Figma variables from design tokens using console scripts, with automatic type mapping and scope assignment. Use when integrating design tokens into Figma, creating variable collections, or automating Figma workflow from token data.

Comprehensive guide for managing Cloudflare DNS with Azure integration. Use when configuring Cloudflare as authoritative DNS provider for Azure-hosted applications, managing DNS records via API, setting up API tokens, configuring proxy settings, troubleshooting DNS issues, implementing DNS security best practices, or integrating External-DNS with Cloudflare for Kubernetes workloads.
