Query Onchain Data

coinbase/agentic-wallet-skills
2.1k installs125 stars
Summary

This lets you run SQL queries against onchain data on Base (blocks, transactions, decoded events) and pay per query using x402 micropayments. It's built on Coinbase's CDP SQL API and uses CoinbaseQL, a ClickHouse dialect. The main thing to know is that queries against the events table must filter on indexed fields (event_signature, contract address, or block_timestamp) or you'll hit performance walls. The skill handles wallet status checks and constructs the npx awal commands with proper escaping to avoid shell injection. Useful when you need to pull Transfer events, analyze contract activity, or grab transaction history without running your own node. The micropayment model means you pay only for what you query, though you need the authenticate-wallet skill set up first.

flags-sdk

vercel/flags

Guide for feature flags and A/B tests with the Flags SDK (`flags` npm package) and Vercel Flags. Use when: declaring flags with `flag()`, using `vercelAdapter` or `vercel flags` CLI (add, list, enable, disable, inspect, archive, rm, sdk-keys), setting up providers/adapters (Vercel, Statsig, LaunchDarkly, PostHog, GrowthBook, Hypertune, Global Config, OpenFeature, Split, Flagsmith, Reflag, Optimizely, or custom adapters), implementing precompute patterns for static pages, setting up `identify`/`dedupe`, integrating Flags Explorer/Toolbar, working with flags in Next.js (App Router, Pages Router, Middleware) or SvelteKit, writing custom adapters, or encrypting/decrypting flag values. Triggers: feature flags, A/B testing, experimentation, flags SDK, flag adapters, precompute, Flags Explorer, feature gates, flag overrides, Vercel Flags, vercel flags CLI, vercel flags add, vercel flags list, vercel flags enable, vercel flags disable, `flags/next`, `flags/sveltekit`, `flags/react`, `@flags-sd

options-payoff

himself65/finance-skills

Generate an interactive options payoff curve chart with dynamic parameter controls. Use this skill whenever the user shares an options position screenshot, describes an options strategy, or asks to visualize how an options trade makes or loses money. Triggers include: any mention of butterfly, spread (vertical/calendar/diagonal/ratio), straddle, strangle, condor, covered call, protective put, iron condor, or any multi-leg options structure. Also triggers when a user pastes strike prices, premiums, expiry dates, or says things like "show me the payoff", "draw the P&L curve", "what does this trade look like", or uploads a screenshot from a broker (IBKR, TastyTrade, Robinhood, etc). Always use this skill even if the user only provides partial info — extract what you can and use defaults for the rest.
