Connection pooling and caching for PostgreSQL and MySQL databases. Load when connecting Workers to existing Postgres/MySQL, reducing connection overhead, using Drizzle/Prisma with external databases, or migrating traditional database apps to the edge.
This skill should be used when the user asks 'what\'s the price of ETH', 'check token price', 'how much is SOL', 'show me the price chart', 'get candlestick data', 'show K-line chart', 'view trade history', 'recent trades for SOL', 'price trend', 'index price', or mentions checking a token\'s current price, viewing price charts, candlestick data, trade history, or historical price trends. Covers real-time on-chain prices, K-line/candlestick charts, trade logs, and index prices across Solana, Ethereum, Base, BSC, Polygon, Arbitrum, and 20+ other chains. For token search, market cap, liquidity analysis, trending tokens, or holder distribution, use okx-dex-token instead.
Provides technical specifications and implementation details for event and conversion ingestion to Google products using the Data Manager API /v1/events/ingest endpoint and its associated client libraries. Use this skill when the user wants to upload offline conversions, enhanced conversions for leads, click conversions, Google Analytics web or app events, or any other event ingestion use case supported by the Data Manager API. Don't use for uploading audience members (use the data-manager-api-audience-ingestion skill).
Use when reviewing or writing new SQL/SQLAlchemy queries, especially in `backend/app/services/`, `backend/app/models/`, or migration files. Catches missing tenant filters, N+1 queries, async-session misuse, and missing indexes before they reach production. Trigger when the user says "review this query", "check for N+1", "is this query safe", or modifies repo-layer code.
Make a canister's data queryable by the Caffeine Data Intelligence agent. Use whenever an app stores structured data (Maps/Lists/arrays of records) that should be answerable in natural language — "top customers", "revenue by region", "active projects". Adds a discoverable `schema()` and a JSON `execute()` query endpoint via the `caffeineai-oql` mops package's `Expose` mixin.
HTTP outcalls performed by the backend canister (not in the frontend).
Clerk authentication router. Use when user asks about adding authentication, setting up Clerk, custom sign-in flows, Next.js patterns, organizations, syncing users, or testing. Automatically routes to the specific skill based on their task.

Paystack Terminal API — build in-person payment experiences with Paystack POS terminals. Send events (invoice/transaction), check terminal status, commission/decommission devices, and manage terminal details. Use this skill whenever integrating Paystack POS terminals, sending payment events to terminals, processing in-person payments, checking terminal availability, activating or deactivating terminal devices, or managing a fleet of POS terminals. Also use when you see references to /terminal endpoint, terminal_id, serial numbers, or event-based terminal communication.
