Guides stable API and interface design. Use when designing APIs, module boundaries, or any public interface. Use when creating REST or GraphQL endpoints, defining type contracts between modules, or establishing boundaries between frontend and backend.
Clerk Organizations for B2B SaaS - create multi-tenant apps with org switching, role-based access, verified domains, and enterprise SSO. Use for team workspaces, RBAC, org-based routing, member management.
**MANDATORY for ALL MCP server work** - mcp-use framework best practices and patterns. **READ THIS FIRST** before any MCP server work, including: - Creating new MCP servers - Modifying existing MCP servers (adding/updating tools, resources, prompts, widgets) - Debugging MCP server issues or errors - Reviewing MCP server code for quality, security, or performance - Answering questions about MCP development or mcp-use patterns - Making ANY changes to server.tool(), server.resource(), server.prompt(), or widgets This skill contains critical architecture decisions, security patterns, and common pitfalls. Always consult the relevant reference files BEFORE implementing MCP features.
Expert-level telecommunications systems, network management, billing, 5G, SDN, and telecom infrastructure
LINE API for messaging. Use when user mentions "LINE", "LINE message", "LINE bot", or asks about LINE platform.
Use this skill when integrating a third-party provider with InsForge — either an auth provider (Clerk, Auth0, WorkOS, Kinde, Stytch) for JWT-based RLS, or a payment facilitator (OKX x402) for onchain pay-per-use billing. Covers provider-specific dashboard setup, client/server code, database policies, and common gotchas for each supported integration.
Build applications with InsForge Backend-as-a-Service. Use when developers need to: (1) Set up backend infrastructure (create tables, storage buckets, deploy functions, configure auth/AI) (2) Integrate InsForge SDK into frontend applications (database CRUD, auth flows, file uploads, AI operations, real-time messaging) (3) Deploy frontend applications to InsForge hosting IMPORTANT: Before any backend work, you MUST have the user's Project URL and API Key. If not provided, ask the user first. Key distinction: Backend configuration uses HTTP API calls to the InsForge project URL. Client integration uses the @insforge/sdk in application code.
This skill should be used when the user asks to 'find a token', 'search for a token', 'look up PEPE', 'what\'s trending', 'top tokens', 'trending tokens on Solana', 'token rankings', 'who holds this token', 'holder distribution', 'is this token safe', 'token market cap', 'token liquidity', 'research a token', 'tell me about this token', 'token info', or mentions searching for tokens by name or address, discovering trending tokens, viewing token rankings, checking holder distribution, or analyzing token market cap and liquidity. Covers token search, metadata, market cap, liquidity, volume, trending token rankings, and holder analysis across Solana, Ethereum, Base, BSC, Polygon, Arbitrum, and 20+ other chains. Do NOT use when the user says only a single generic word like 'tokens' or 'crypto' without specifying a token name, action, or question. For simple current price checks, price charts, candlestick data, or trade history, use okx-dex-market instead.
Use this skill when integrating a third-party auth provider (Clerk, Auth0, WorkOS, Kinde, Stytch) with InsForge for authentication and RLS. Covers JWT configuration, client setup, database RLS policies, and provider-specific gotchas for each supported integration.
Use when building, refactoring, or documenting Graft apps and proxies, including when asked to create a tool server, API server, dual-protocol server, or MCP-HTTP bridge. Graft's core thesis: define tools once and serve them as both HTTP REST endpoints and MCP tools from the same server, with discovery, docs, and OpenAPI generated automatically. Covers concrete actions such as defining tools and handlers, configuring authentication middleware, setting up HTTP and stdio transports, generating OpenAPI documentation, wrapping existing APIs via proxy mode, and wiring up the full CLI workflow.
Master REST and GraphQL API design principles to build intuitive, scalable, and maintainable APIs that delight developers. Use when designing new APIs, reviewing API specifications, or establishing API design standards.
GraphQL performance optimization and best practices for building scalable APIs. This skill should be used when writing, reviewing, or refactoring GraphQL schemas, resolvers, or query execution code. Triggers on tasks involving GraphQL APIs, resolver optimization, query performance, or data fetching patterns.
