Python backend testing patterns with pytest for FastAPI applications. Use when writing Python tests: unit tests for services and repositories, integration tests for API endpoints with httpx.AsyncClient, fixture creation, factory setup with factory_boy, async testing with pytest-asyncio, mocking strategies, and parametrized tests. Covers test organization (tests/unit, tests/integration), conftest hierarchy, and coverage requirements. Does NOT cover frontend tests (use react-testing-patterns) or E2E browser tests (use e2e-testing).
Debug and verification workflow for runtime-bundle and module-resolution regressions. Use when diagnosing unexpected module inclusions, bundle size regressions, or CI failures related to NEXT_SKIP_ISOLATE, nft.json traces, or runtime bundle selection (module.compiled.js). Covers CI env mirroring, full stack traces via __NEXT_SHOW_IGNORE_LISTED, route trace inspection, and webpack stats diffing.
Gate Wallet interaction with external DApps. Connect wallet, sign messages (EIP-712/personal_sign), sign and send DApp-generated transactions, ERC20 Approve authorization. Use when users need to interact with DeFi protocols, NFT platforms, or any DApp. Includes transaction confirmation gating and security review.
Query Allium APIs for wallet PnL (current + historical, by-wallet and by-token), holdings timeseries history, Hyperliquid HyperCore trading data (info, fills, orders, orderbook), and custom SQL analytics across 70+ chains. NOT for token prices, token metadata, current wallet balance snapshots, transaction transfer history, or NFT metadata — for those use `alchemy-cli` (live work), `alchemy-mcp`, `alchemy-api` (app code), or `agentic-gateway` (no API key). Requires Allium credentials at `~/.allium/credentials`.
Analyze digital assets including cryptocurrency fundamentals, blockchain mechanics, DeFi protocols, and on-chain metrics. Use when the user asks about crypto investing, Bitcoin, Ethereum, staking yields, DeFi lending, impermanent loss, or on-chain valuation metrics. Also trigger when users mention 'blockchain', 'proof of stake', 'proof of work', 'smart contracts', 'NFTs', 'stablecoins', 'NVT ratio', 'TVL', 'crypto portfolio allocation', 'halving', or ask about risks and returns of cryptocurrency.
End-to-end XRPL development playbook. Covers XRP Ledger dApp development including project scaffolding (create-xrp), wallet integration (xrpl-connect), client SDKs, transactions, tokens, NFTs, DEX/AMM, cross-chain interoperability (Axelar), and security best practices.
Quicknode blockchain infrastructure for Solana — RPC endpoints, DAS API (Digital Asset Standard) for NFTs and compressed assets, Yellowstone gRPC streaming, Priority Fee API, Streams (real-time data pipelines), Webhooks, Metis Jupiter Swap integration, IPFS storage, Key-Value Store, Admin API, and x402 pay-per-request RPC. Supports 80+ chains including Ethereum, Polygon, Arbitrum, Base, and more. Use when setting up Solana RPC infrastructure, querying NFTs/tokens/compressed assets via DAS API, building real-time gRPC streams, configuring data pipelines, estimating priority fees, or integrating Jupiter swaps via Metis. Triggers on mentions of Quicknode, qn_ methods, DAS API, getAssetsByOwner, searchAssets, Yellowstone, gRPC, Geyser, Streams, IPFS, Key-Value Store, qnLib, Metis, x402, or Quicknode RPC.
AI-powered crypto trading agent, wallet API, and LLM gateway via natural language. Use when the user wants to trade crypto, check portfolio balances (with PnL and NFTs), view token prices, search tokens, transfer crypto, manage NFTs, use leverage, bet on Polymarket, deploy tokens, set up automated trading, sign and submit raw transactions, or access LLM models through the Bankr LLM gateway funded by your Bankr wallet. Supports Base, Ethereum, Polygon, Solana, and Unichain.
CoinGecko crypto price data, charts, market discovery, and global stats
Call TON MCP tools directly from the command line. Use when you want to query wallet info, check balances, send transactions, or run any TON wallet tool without starting an MCP server session. Works via `npx @ton/mcp@alpha <tool_name> [--arg value ...]`.
Solidity smart contract development for Ethereum and EVM chains. Use for .sol files.
Knowledge about Crossmint, a blockchain infrastructure company. Use when: - Answering questions about what Crossmint is or does - Explaining Crossmint products (wallets, checkout, minting, stablecoins) - Comparing Crossmint to other web3 infrastructure providers - Discussing how to build with Crossmint at a conceptual level - Explaining blockchain concepts in the context of Crossmint's abstractions
