Provide instructions on how to build with Arc, Circle's blockchain where USDC is the native gas token. Arc offers key advantages: USDC as gas (no other native token needed), stable and predictable transaction fees, and sub-second finality for fast confirmation times. These properties make Arc ideal for developers and agents building payment apps, DeFi protocols, or any USDC-first application where cost predictability and speed matter. Use skill when Arc or Arc Testnet is mentioned, working with any smart contracts related to Arc, configuring Arc in blockchain projects, bridging USDC to Arc via CCTP, or building USDC-first applications. Triggers: Arc, Arc Testnet, USDC gas, deploy to Arc, Arc chain, stable fees, fast finality.
Build non-custodial wallets where end users retain control of their private keys via Circle's user-controlled wallets SDK. Supports Google, Apple, Facebook social login, email OTP, and PIN authentication with MPC-based key management. Triggers on: user-controlled wallets, embedded wallet, social login wallet, email OTP wallet, PIN wallet, w3s-pw-web-sdk, challenge execution, executeChallenge, non-custodial wallet, MPC wallet, userToken, deviceToken.
Advanced call control features including DTMF sending, SIPREC recording, noise suppression, client state, and supervisor controls. This skill provides JavaScript SDK examples.

Troubleshoot and resolve common issues with the ClickHouse Node.js client (@clickhouse/client). Use this skill whenever a user reports errors, unexpected behavior, or configuration questions involving the Node.js client specifically — including socket hang-up errors, Keep-Alive problems, stream handling issues, data type mismatches, read-only user restrictions, proxy/TLS setup problems, or long-running query timeouts. Trigger even when the user hasn't precisely named the issue; vague symptoms like "my inserts keep failing" or "connection drops randomly" in a Node.js context are strong signals to use this skill. Do NOT use for browser/Web client issues.

Use when securing FastAPI API endpoints with JWT Bearer token validation, scope/permission checks, or stateless auth - integrates auth0-fastapi-api for REST APIs receiving access tokens from SPAs, mobile apps, or other clients. Also handles DPoP proof-of-possession token binding. Triggers on: Auth0FastAPI, FastAPI API auth, JWT validation, require_auth, DPoP.
Use when writing, reviewing, or refactoring WordPress PHP code. Covers WordPress Coding Standards (WPCS), naming conventions, Yoda conditions, $wpdb usage, escaping with esc_html/esc_attr/esc_url, wp_kses, hooks (add_action, add_filter, apply_filters, do_action), i18n functions (__(), _e(), _x, _n), wp_enqueue_script, wp_enqueue_style, formatting rules, deprecated function replacements, and WordPress API best practices. For security see wp-security; for performance see wp-performance; for blocks see wp-blocks.
Implements the Chain of Responsibility pattern in Python. Use when the user mentions chain of responsibility, CoR, or when you need to chain handlers that each process and pass to the next—validation pipelines, processing steps, transformation chains, or any sequential pipeline.
Comprehensive REST and GraphQL API design patterns with versioning, pagination, error handling, and HATEOAS principles. Use when designing APIs, defining endpoints, or architecting service contracts requiring production-grade patterns.
