evalanche
by iJaack
Multi-EVM agent wallet SDK with onchain identity (ERC-8004), payment rails (x402), cross-chain bridging (Li.Fi), and destination gas funding (Gas.zip). Supports 21+ EVM chains: Ethereum, Base, Arbitrum, Optimism, Polygon, BSC, Avalanche, and more. Agents generate and manage their own keys — no human input required. Use when: booting an autonomous agent wallet on any EVM chain, sending tokens, calling contracts, resolving agent identity, checking reputation, making x402 payment-gated API calls, bridging tokens cross-chain (Li.Fi), funding gas on destination chains (Gas.zip), cross-chain transfers (Avalanche C↔X↔P), delegating stake, querying validators, signing messages, creating subnets, managing L1 validators, adding validators with BLS keys, querying node info. Don't use when: managing ENS (use moltbook scripts). Network: yes (EVM RPCs via Routescan + public fallbacks). Cost: gas fees per transaction.

NextDNS Web UI configuration and management best practices. This skill should be used when
tempo
by tempoxyz
Use this skill when the user wants to call an API, make an HTTP request, discover available services, or access external data with automatic payments. Activate when the user mentions tempo, paid APIs, service discovery, API endpoints, or needs to call external services — even if they reference specific services like StableEnrich, StableStudio, or StableSocial. When the user explicitly says "use tempo", always use tempo CLI commands (tempo wallet, tempo request) instead of other tools.
crypto
by florianbuetow
This skill should be used when the user asks to "check for cryptographic issues", "analyze encryption", "find weak hashing", "audit password storage", "check for hardcoded keys", or mentions "cryptography", "encryption", "hashing", "TLS", "certificates", or "random number generation" in a security context. Maps to OWASP Top 10 2021 A02: Cryptographic Failures.
