Expert knowledge for DeFi/MEV bot development including critical pitfalls, backtesting realities, AMM mechanics, MEV extraction strategies, and production failure modes
DeFi protocol expert ensuring correct data formats, types, denominations, and API structures. MUST be consulted before writing ANY protocol integration code. Triggers on ANY mention of Aave, Compound, Uniswap, Curve, Balancer, or DeFi terms like liquidation, swap, flash loan, health factor.
DEX liquidity analysis and slippage estimation for MEV trading. Use when implementing swaps, route selection, or position sizing. Triggers on: liquidity, slippage, price impact, depth, AMM math, Uniswap, Curve.
Blockchain RPC error handling, gas estimation, multi-chain config, and transaction management. Use when interacting with smart contracts, estimating gas, or managing transactions. Triggers on: RPC, contract call, gas, multicall, nonce, transaction, revert.
This skill should be used when the user asks about "AIR", "algebraic intermediate representation", "ZK constraints", "trace design", "constraint soundness", "polynomial commitments", "FRI", "STARK", "lookup arguments", "permutation arguments", "memory consistency", "transition constraints", "boundary constraints", "vanishing polynomial", "quotient polynomial", "Fiat-Shamir", or needs expert-level cryptographic review of constraint systems.
Write a bot to continuously listen and respond to events on a public blockchain network.
Develop Cairo contracts for Eternum with strict TDD workflow - plan, test first, then implement
Sign in to the wallet. Use when you or the user want to log in, sign in, connect, or set up the wallet, or when any wallet operation fails with authentication or "not signed in" errors. This skill is a prerequisite before sending, trading, or funding.
Comprehensive verification system for construction automation deliverables. Use after completing estimates, schedules, reports, or data processing tasks to ensure quality.
Docusaurus build health validation and deployment safety for Claude Skills showcase. Pre-commit MDX validation (Liquid syntax, angle brackets, prop mismatches), pre-build link checking, post-build health reports. Activate on 'build errors', 'commit hooks', 'deployment safety', 'site health', 'MDX validation'. NOT for general DevOps (use deployment-engineer), Kubernetes/cloud infrastructure (use kubernetes-architect), runtime monitoring (use observability-engineer), or non-Docusaurus projects.
Validates that a DAG node's output matches its declared JSON schema before passing to downstream nodes. The glue that makes multi-agent DAGs reliable. Use when checking output contract compliance, generating validation schemas from descriptions, or debugging contract mismatches between nodes. Activate on "validate output", "output contract", "schema validation", "contract mismatch", "output doesn't match". NOT for content quality assessment (use dag-quality), skill grading (use skill-grader), or general JSON schema work outside DAG context.
Use when exploring Web3 marketing strategies for Xiaohongshu, implementing NFT campaigns, building blockchain communities, engaging crypto-native audiences, or integrating decentralized technologies with traditional marketing
Builds redstone circuits, mechanisms, and automation in Minecraft using VibeCraft MCP tools. Use when building logic gates, memory circuits, piston doors, automatic farms, item sorters, clocks, or any redstone contraption.
Chooses Minecraft block materials, color palettes, and textures using VibeCraft MCP tools. Use when selecting materials for builds, creating color schemes, matching architectural styles, or asking about block combinations and palettes.
Best practices for Flutter mobile app security. Use when reviewing or writing code that handles secrets, user data, network communication, authentication, or cryptography. Covers static security concerns — not pen-testing or runtime analysis.
Comprehensive Solidity contract security scanner detecting 104 vulnerability patterns across reentrancy, access control, arithmetic, DeFi, proxy, and token categories. Integrates Slither, Aderyn, and Mythril with manual analysis.
Analyzes storage layout, proxy patterns, and state variable security in Solidity contracts. Detects storage collisions, uninitialized pointers, and upgrade risks. Use when auditing proxy/upgradeable contracts.
Validates Solidity implementation against specification documents. Extracts behavior from docs (README, specs, NatSpec) and verifies code matches documented intent. Uses Trail of Bits methodology for divergence detection.
Deep reentrancy vulnerability analysis for Solidity contracts. Covers single-function, cross-function, cross-contract, and read-only reentrancy. Maps all external call paths and validates CEI pattern compliance.
Analyzes Solidity contract entry points to map attack surface. Identifies all external/public functions, categorizes by privilege level, maps access control, and detects authorization patterns. Use as first step in any audit.
