Build, validate, and interact with Modality contracts — append-only logs of signed commits governed by predicate-guarded state machine models. Use when implementing contract validators, hub services, CLI contract commands, contract APIs, or writing/reviewing any code that touches Modality contract commit processing, rule enforcement, or model validation.
Build, balance, and sign Cardano transactions in Haskell using sc-tools (`Convex.BuildTx` for constructing unbalanced transactions; `Convex.CoinSelection` for coin selection/balancing/signing; `Convex.Query`/Blockfrost/node/mockchain backends for fetching inputs). Use when writing or debugging off-chain code that adds inputs/outputs/mints/withdrawals/collateral/reference scripts, sets validity intervals and required signers, or fixes balancing/script execution/submission failures.
Create, sign, and verify Modality contracts for trustless agent cooperation. Use when an agent needs to establish a binding agreement with another agent, delegate a task with enforceable terms, verify a contract's protections, or participate in a multi-party contract. Handles escrow, task delegation, data exchange, multisig, and custom contract patterns.
Implement AP2 dispute resolution and accountability — cryptographic evidence, liability allocation, chargeback handling, and audit trail construction. Use when building dispute handling, fraud investigation, or compliance systems for agentic payments.
Interact with EVM-compatible blockchains using Foundry's cast tool for querying balances, calling contracts, sending transactions, and blockchain exploration. Use when needing to interact with Ethereum Virtual Machine networks via command-line, including reading contract state, sending funds, executing contract functions, or inspecting blockchain data.
Implement AP2 dispute resolution and accountability — cryptographic evidence, liability allocation, chargeback handling, and audit trail construction. Use when building dispute handling, fraud investigation, or compliance systems for agentic payments.
Build and operate the "Governance Community Feedback Harvester" capability for Safety and Governance. Use only when production execution explicitly requires this exact capability and output contract.
Senior Unity Developer quality review. Deep-dives into a Unity project, reviews everything against best practices, and produces a comprehensive HTML report document. Read-only — never modifies any project files. Covers: architecture, code quality, performance, Unity best practices, project health, security, testing, asset management, and technical debt. Use when: (1) Full project quality audit, (2) Pre-release readiness check, (3) Technical debt assessment, (4) Onboarding review to understand project health, (5) Periodic quality gate evaluation, (6) Post-mortem quality analysis. Triggers: 'review quality', 'quality audit', 'project review', 'quality check', 'project health', 'best practices review', 'code audit', 'technical debt review', 'quality report', 'full review', 'project audit'.
Performs comprehensive codebase audit checking architecture, tech debt, security, test coverage, documentation, dependencies, and maintainability. Use when auditing a project, assessing codebase health, or asked to audit/analyze the entire codebase.
Audit codebase for security vulnerabilities, secret leakage, dependency risks, and configuration issues. Use before commits, when adding dependencies, or reviewing PRs. Enforces zero-secrets policy, dependency isolation, and secure build practices.
This skill should be used when the user asks to "deploy application", "deploy to production", "release app", "deploy to AWS", "deploy to Vercel", "deploy to Kubernetes", "iOS deployment", "Android deployment", "deploy smart contract", "web3 deployment", "deploy to multiple platforms", or needs guidance on deployment strategies across web, mobile, and blockchain platforms.
Expert security auditor specializing in comprehensive security assessments, compliance validation, and risk management. Masters security frameworks, audit methodologies, and compliance standards with focus on identifying vulnerabilities and ensuring regulatory adherence.
Operate the "Handoff Contracting for disaster response networks" capability in production for disaster response networks workflows. Use when mission execution explicitly requires this capability and outcomes must be reproducible, policy-gated, and handoff-ready.
Comprehensive knowledge for XPR Network blockchain development - smart contracts, CLI, web SDK, DeFi, NFTs, and infrastructure
"Expert security auditor specializing in DevSecOps, comprehensive"
skill for developing and maintaining TypeScript utility libraries transpiled to esm. Use this skill when working on TypeScript projects that involve creating reusable utility functions, managing library structure, testing, documentation, and build processes. This includes creating new utilities, refactoring existing code, setting up testing frameworks, configuring build tools, and ensuring type safety.
Validate Kubernetes, Terraform, Helm, GitHub Actions, and Docker configs. Use when user says "deploy check", "validate deployment", "check k8s", "validate infrastructure", "check configs", or wants to verify infrastructure.
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
Security audit for vulnerabilities, compliance issues, and sensitive data exposure. Use before production deployments or when reviewing security-sensitive code.
