Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/mindrally/skills --skill ethereum- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads ethereum automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Ethereum Development
You are an expert in Ethereum smart contract development with Solidity and modern tooling.
Core Philosophy
Cut the fluff. Code or detailed explanations only. Keep it casual and brief. Accuracy and depth matter.
General Principles
- Prioritize logic over citations
- Embrace emerging technologies and unconventional solutions
- Flag speculative content clearly
- Omit ethical disclaimers unless critical for security
- Place sources at conclusion, not mid-text
- Provide complete code implementations without shortcuts
Solidity Best Practices
Code Standards
- Explicit visibility modifiers and NatSpec documentation
- Function modifiers for recurring checks and validation
- CamelCase for contracts, PascalCase for interfaces (prefix "I")
- Interface Segregation Principle for maintainability
- Proxy patterns for upgradeability
Security Patterns
- Comprehensive event logging for state modifications
- Checks-Effects-Interactions pattern for reentrancy prevention
- Pull-over-push payment mechanisms
- Rate limiting on sensitive operations
- ReentrancyGuard for additional protection
- Custom errors instead of revert strings
OpenZeppelin Integration
- AccessControl for granular permissions
- SafeERC20 for token interactions
- Pausable for circuit breakers
- ERC20Snapshot, ERC20Permit, ERC20Votes for specialized tokens
- TimelockController for sensitive operations
- Address library for safe external calls
Optimization
- Solidity 0.8.0+ for built-in overflow/underflow protection
- Gas-efficient storage packing
- Assembly for performance-critical sections (with documentation)
- Immutable variables for compile-time constants
- Libraries for reducing contract size
Testing & Analysis
- Unit, integration, and end-to-end test coverage
- Property-based testing for edge cases
- Slither and Mythril static analysis
- High coverage on critical paths
- Security audits and bug bounties
Development Workflow
- Hardhat for testing and debugging
- CI/CD pipelines for deployments
- Pre-commit linting and type checking
- Architecture diagrams and decision logs
FAQ
What does the ethereum skill do?
Expert guidelines for Ethereum smart contract development with Solidity, OpenZeppelin, and Hardhat
How do I install ethereum?
Run npx skills add https://github.com/mindrally/skills --skill ethereum in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/ethereum/ (personal) or .claude/skills/ethereum/ (project).
Which AI agents can use ethereum?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is ethereum safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains ethereum?
It is published by mindrally in mindrally/skills. It has 742 recorded installs.

sales-enablement
coreyhaines31/marketingskills
When the user wants to create sales collateral, pitch decks, one-pagers, objection handling docs, or demo scripts. Also use when the user mentions 'sales deck,' 'pitch deck,' 'one-pager,' 'leave-behind,' 'objection handling,' 'deal-specific ROI analysis,' 'demo script,' 'talk track,' 'sales playbook,' 'proposal template,' 'buyer persona card,' 'battle card,' 'battlecard,' 'competitive one-pager,' 'win-loss analysis,' 'why are we losing deals,' 'loss reasons,' 'how do I respond to this objection,' 'prospect just said,' 'help my sales team,' 'sales materials,' or 'what should I give my sales reps,' 'cold call script,' or 'voicemail script.' Use this for any document or asset that helps a sales team close deals. For public competitor comparison pages, see competitors. For running buyer interviews or churn research, see customer-research. For marketing website copy, see copywriting. For cold outreach emails, see cold-email. For the offer being sold (bonuses, guarantees, pricing structure),
revops
coreyhaines31/marketingskills
When the user wants help with revenue operations, lead lifecycle management, or marketing-to-sales handoff processes. Also use when the user mentions 'RevOps,' 'revenue operations,' 'lead scoring,' 'outbound pipeline stages,' 'lead routing,' 'MQL,' 'SQL,' 'pipeline stages,' 'deal desk,' 'CRM automation,' 'marketing-to-sales handoff,' 'data hygiene,' 'leads aren't getting to sales,' 'pipeline management,' 'lead qualification,' or 'when should marketing hand off to sales.' Use this for anything involving the systems and processes that connect marketing to revenue. For cold outreach emails, see cold-email. For email drip campaigns, see emails. For pricing decisions, see pricing.
sales-funnel-blueprint
autonnel/autonnel-skills
Turn an offer into a concrete multi-step sales funnel spec - page-by-page structure, price ladder, copy outline and the metrics each step must hit. Use when asked to build a sales funnel, marketing funnel, landing page flow, lead magnet funnel, webinar funnel, tripwire or VSL funnel, when planning a product launch page flow, or when someone asks "what pages do I need" for selling something online.
pricing
coreyhaines31/marketingskills
When the user wants help with pricing decisions, packaging, or monetization strategy. Also use when the user mentions 'pricing,' 'pricing tiers,' 'freemium,' 'free trial,' 'packaging,' 'price increase,' 'value metric,' 'Van Westendorp,' 'willingness to pay,' 'monetization,' 'how much should I charge,' 'my pricing is wrong,' 'pricing page,' 'annual vs monthly,' 'per seat pricing,' 'should I offer a free plan,' 'pricing page teardown,' 'pricing page audit,' 'is my pricing page AI-readable,' or 'can AI read my pricing.' Use this whenever someone is figuring out what to charge, how to structure their plans, or wants to audit a pricing page (for humans and for the AI agents that shortlist tools). For in-app upgrade screens, see paywalls. For offer construction (bonuses, guarantees, value framing, naming) on services/courses/coaching/high-ticket B2B, see offers.
