x402-payments
by Aznatkoiny
Build applications using the x402 protocol — Coinbase's open standard for HTTP-native stablecoin payments using the HTTP 402 status code. Use this skill when: - Creating APIs that require USDC payments per request (seller/server side) - Building clients or AI agents that pay for x402-protected resources (buyer/client side) - Implementing MCP servers with paid tools for Claude Desktop - Adding payment middleware to Express, Hono, or Next.js applications - Working with Base (EVM) or Solana (SVM) payment flows - Building machine-to-machine or agent-to-agent payment systems - Integrating micropayments, pay-per-use billing, or paid API access Triggers: x402, HTTP 402, payment required, USDC payments, micropayments, pay-per-use API, agentic payments, stablecoin payments, paid API endpoint, paywall middleware

token-reduce
by chimera-defi
Reduce total token usage across AI coding tasks by keeping discovery, reading, and follow-up context minimal. Use when file location is uncertain, the repo is large, or the user asks to explore, review, gather context, or work across multiple files. Prefer QMD BM25 when available; otherwise fall back to scoped rg. Skip for small edits with an exact file path.
project0
by 0dotxyz
Permissionless DeFi yield and credit on Solana via the Project 0 (P0) protocol. Deposit funds to earn yield across Solana's highest-yielding venues. Borrow stablecoins against deposited collateral instead of selling crypto. Execute advanced yield strategies via rate arbitrage and looping. All operations are on-chain and permissionless -- no accounts, no approval process. Note: This skill requires a wallet keypair to sign transactions. Use a dedicated wallet with limited funds -- never expose your main private key. The agent will always ask for confirmation before signing. Read-only operations need no keypair.

Open-source first AI inference — GLM-5 as default, Claude as fallback only. Own your inference forever via the Morpheus decentralized network. Stake MOR tokens, access GLM-5, GLM-4.7 Flash, Kimi K2.5, and 30+ models with persistent inference by recycling staked MOR. Open-source first model router routes all tiers to Morpheus by default — Claude only kicks in as an escape hatch when needed. Includes Morpheus API Gateway bootstrap for zero-config startup, OpenAI-compatible proxy with auto-session management, automatic retry with fresh sessions, OpenAI-compatible error classification to prevent cooldown cascades, multi-key auth rotation v2 with proactive DIEM balance monitoring and reactive 402 watchdog, Gateway Guardian v5 with direct curl inference probes (eliminates Signal spam), proactive Venice DIEM credit monitoring, circuit breaker for stuck sub-agents, nuclear self-healing restart, always-on proxy-router with launchd auto-restart, smart session archiver, three-shift cyclic execution engine (v2 with 15-minute execution loops), 24/7 always-on power configuration for macOS, bundled security skills, zero-dependency wallet management via macOS Keychain, x402 payment client for agent-to-agent USDC payments, and ERC-8004 agent registry reader for discovering trustless agents on Base.
