Design and build reactive, type-safe, production-grade backends on Convex. Covers schema, queries/mutations/actions, indexes, auth, file storage, scheduling, real-time multiplayer, mobile backends, and LLM/agent workflows on Convex's one-platform stack.
Add a capability to the CURRENT Convex app — consults the served Convex capability catalog for always-current procedures (billing, crons, auth, agent, search, …); falls back to built-in hosting or @convex-dev component search. TRIGGER when the user runs /add, or asks to add hosting/publishing or any backend capability to an existing Convex app.
Read the Convex deployment's 72h insights (read limits, OCC contention), root-cause each event in code, report evidence-backed perf/cost findings with fixes.
Suggest the matching Convex component when the user hand-rolls a pattern it already solves (crons, sharded-counter, rate-limiter, storage, search, presence, workflow, RAG, prosemirror-sync). Passive — suggest after the task, never interrupt. Never install without consent.
Build automated billing systems for recurring payments, invoicing, subscription lifecycle, and dunning management. Use when implementing subscription billing, automating invoicing, or managing recurring payment systems.
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.
Write idiomatic application code with the ClickHouse Node.js client (`@clickhouse/client`). Use this skill whenever a user is *building* against the Node.js client — configuring the client, pinging, inserting rows in JSON or raw formats, selecting and parsing results, binding query parameters, managing sessions and temporary tables, working with data types or customizing JSON parsing. Do NOT use for browser/Web client code.
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.
General file/object storage, such as for images, videos, files, documents and other bulk data. Perfect fit for image galleries, video galleries, and other file or object management. Supports large files beyond IC limit, with browser-cached HTTP URL access.

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.
