Use when building blockchain applications or smart contracts across EVM (Solidity), Solana (Anchor/Rust), Cosmos (CosmWasm), and TON, including security/audit workflows, fuzz/invariant testing, upgrades, custody/signing, and backend integration (RPC, indexers, webhooks).
Smart contracts are self-executing programs on blockchain. This guide covers Solidity basics, contract deployment, interaction, and frontend integration for building decentralized applications with au
Comprehensive quality audit before phase completion or deployment. Performs planning conformance, DDD validation, security checks, tests, browser verification, and quantitative metrics. Also enforces verification-before-completion discipline — no claims without evidence. Run this skill before deploying, before merging a PR, after completing significant changes, and whenever anyone claims 'it works' or 'tests pass'. Triggers immediately on 'quality check', 'pre-deploy check', 'audit this', 'QA', 'verify this', 'does this work', '품질 검사', '배포 전 검사'. Trigger: /audit, /evaluate, /verify.

Use when the task says the customer ALREADY HAS an unpaid invoice and asks to register/record the payment. Keywords: 'facture impayée', 'unbezahlte Rechnung', 'ubetalt faktura', 'unpaid invoice', 'fatura pendente'. The invoice ALREADY EXISTS — do NOT create a new one. If the task mentions creating products, orders, or new invoices, use order_invoice_payment instead.
This skill should be used when the task asks to "create an invoice", "send an invoice", "crie uma fatura", "opprett ein faktura", "opprett en faktura", "erstelle eine Rechnung", "créer une facture", "crear una factura", "envoyez une facture", or involves creating and optionally sending an invoice to a customer in Tripletex.
This skill should be used when the task asks to "create a credit note", "issue a credit memo", "erstellen Sie eine Gutschrift", "créer un avoir", "opprett ein kreditnota", "criar uma nota de crédito", "crear una nota de crédito", "emita una nota de crédito", "émettre un avoir", or involves cancelling/nullifying an existing invoice by creating a credit note.
