Building & extending Pi — authoring TypeScript extensions (ExtensionAPI, registerTool, registerProvider, /commands, UI hooks), publishing as npm/git packages (pi-package), embedding via JSON-RPC mode (--mode rpc/json, JSONL framing, AgentSession SDK), and developing inside the pi_agent_rust repo. Use for any "how do I build a Pi extension/package/SDK client" question.
Query OpenSea marketplace data — listings, offers, sales / events, floor prices, collection stats, drops, traits — and execute Seaport trades via the official `@opensea/cli` and OpenSea REST API across Ethereum, Base, Arbitrum, Optimism, Polygon, and more. Includes search across collections / NFTs / tokens / accounts. NOT for general NFT metadata reads (name, image, traits, ownership), token metadata, current wallet balances, transaction history, or live RPC reads — for those use `alchemy-cli` (live), `alchemy-mcp`, `alchemy-api` (app code), or `agentic-gateway` (no API key). For pure cross-chain token swaps (no marketplace context), prefer the `lifi` ecosystem skill. Requires `OPENSEA_API_KEY` (instant via API).
Server-side authentication primitives for TanStack Start: session cookies (HttpOnly, Secure, SameSite, __Host- prefix), session read/issue/destroy via createServerFn and middleware, OAuth authorization-code flow with state and PKCE, password-reset enumeration defense, CSRF for non-GET RPCs, rate limiting auth endpoints, session rotation on privilege change. Pairs with router-core/auth-and-guards for the routing side.
Structure services with Encore Go.
Hono ultrafast web framework for edge computing. Use for edge APIs.
Critical Bitcoin terminology rules to prevent confusion between bech32m (encoding) and taproot (address type). Use when working on BTC-related code, config files, or shell scripts.
Use when building or maintaining Electrobun desktop apps in TypeScript, including electrobun.config.ts, electrobun/bun or electrobun/view imports, BrowserWindow/BrowserView usage, updater flows, and distribution artifacts.
Interact with EVM-compatible blockchains using Foundry's cast tool for querying balances, calling contracts, sending transactions, and blockchain exploration. Use when needing to interact with Ethereum Virtual Machine networks via command-line, including reading contract state, sending funds, executing contract functions, or inspecting blockchain data.
Supabase backend development workflow. Use for ANY backend work in Supabase projects — schema changes, API endpoints, database functions, RLS policies, edge functions, auth, storage, business logic, or data access. Activate whenever the task involves server-side logic, data layer, or Supabase features.
How to read and query onchain data — events, The Graph, indexing patterns. Why you cannot just loop through blocks, and what to use instead.
View what a wallet holds on DFlow's Kalshi prediction markets — current positions, unrealized mark-to-market, realized P&L, activity history, and redeemable winners. Use when the user asks "what are my positions?", "what do I own?", "am I up or down?", "what's my fill history?", "what can I redeem?", "mark my portfolio to market", or "show me this wallet's DFlow activity". Read-only. Do NOT use to place sells or redemptions (use `dflow-kalshi-trading`), for market-wide data unrelated to a wallet (use `dflow-kalshi-market-data`), or to discover new markets (use `dflow-kalshi-market-scanner`).
Use the Alchemy MCP server (`https://mcp.alchemy.com/mcp`) for live blockchain data and admin work when MCP is wired into your AI client and the Alchemy CLI is NOT installed locally. Exposes 159 tools across 100+ chains for token prices, NFT metadata, transactions, simulation, tracing, account abstraction, Solana DAS, and app management. Use for live querying, analysis, admin work, or on-machine agent work — not for application code that ships to production. For application code, use the `alchemy-api` skill (with API key) or `agentic-gateway` skill (without). When the CLI is also installed locally, prefer `alchemy-cli` instead.
