Calibrate an LLM judge against human labels using data splits, TPR/TNR, and bias correction. Use after writing a judge prompt (write-judge-prompt) when you need to verify alignment before trusting its outputs. Do NOT use for code-based evaluators (those are deterministic; test with standard unit tests).
Integrate Dojo with game clients for JavaScript, Unity, Unreal, Rust, and other platforms. Generate typed bindings and connection code. Use when connecting frontends or game engines to your Dojo world.
Email marketing specialist covering email sequences, newsletters, automation workflows, deliverability, list management, and transactional emails. Use when the user wants to write emails, create drip campaigns, set up welcome sequences, design nurture flows, improve open rates, reduce unsubscribes, plan newsletters, set up email automation, segment audiences, or optimize email deliverability. Also triggers for subject line optimization, email copywriting, A/B testing emails, or ESP selection.
When the user wants to plan email marketing, EDM, newsletter strategy, or email deliverability. Also use when the user mentions "email marketing," "EDM," "newsletter," "SPF," "DKIM," "DMARC," "email deliverability," "email content strategy," "email campaigns," "newsletter strategy," "email automation," or "cold email."
Solidity security patterns, common vulnerabilities, and pre-deploy audit checklist. The specific code patterns that prevent real losses — not just warnings, but defensive implementations. Use before deploying any contract, when reviewing code, or when building anything that holds or moves value.
Ethereum development knowledge for AI agents — from idea to deployed dApp. Fetch real-time docs on gas costs, Solidity patterns, Scaffold-ETH 2, Layer 2s, DeFi composability, security, testing, and production deployment. Use when: (1) building any Ethereum or EVM dApp, (2) writing or reviewing Solidity contracts, (3) deploying to mainnet or L2s, (4) the user asks about gas, tokens, wallets, or smart contracts, (5) any web3/blockchain/onchain development task. NOT for: trading, price checking, or portfolio management — use a trading skill for those.
SOLID principles for object-oriented design — Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion. Covers motivation, violations, fixes, and multi-language examples (PHP, Java, Python, TypeScript, C++) for building maintainable, extensible software.
Smart contract and secure API contract security analysis — invariant checking, access control, reentrancy, and integer overflow patterns. Implements Checks-Effects-Interactions pattern, formal invariant verification, and OpenSCV vulnerability taxonomy for Solidity/EVM and Rust/Solana contracts.
Use when testing a web application for security vulnerabilities, before deployment or during security review — guides through a structured 10-phase penetration testing methodology covering mapping, authentication, session management, access controls, injection, logic flaws, and server configuration.
Unified UI/UX operating system for planning, designing, implementing, and auditing modern interfaces across web and mobile stacks. Use when requests involve creating, redesigning, reviewing, fixing, or optimizing pages/components (landing pages, dashboards, SaaS apps, admin panels, e-commerce, portfolios, blogs, mobile screens) and require strong visual direction plus accessibility, interaction, performance, and responsive quality.
Concurrency exploitation — race conditions, TOCTOU vulnerabilities, and parallel request abuse in web applications.
Test for security vulnerabilities using OWASP principles. Use when conducting security audits, testing auth, or implementing security practices.
