solidity-best-practices SKILL.md skillA
solidity-best-practices from nirholas/three.ws is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nirholas/three.ws/solidity-best-practices@git:20260501.87cefc9Pins git:20260501.87cefc9 in mdr.lock. Pin the fingerprint instead.

Guide for writing secure, gas-efficient, and maintainable Solidity smart contracts following established patterns and avoiding common pitfalls.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Solidity Best Practices ## When to use this skill Use when the user asks about: - Writing or reviewing Solidity code - Smart contract design patterns - Gas optimization techniques in Solidity - Security best practices for contract development - Structuring a Solidity project ## Development Guidelines ### 1. Project Structure Recommended contract organization: - `contracts/` — main contract source files - `contracts/interfaces/` — interface definitions (IProtocol.sol) - `contracts/libraries/` — shared library code - `contracts/utils/` — utility contracts (access control, pausable, etc.) - `test/` — test files mirroring the contracts directory structure - `script/` — deployment and interaction scripts ### 2. Coding Standards Follow these Solidity style conventions: - Use Solidity 0.8.x or later (built-in overflow checks) - Specify exact compiler version with `pragma solidity 0.8.24;` (not floating `^`) - Order contract elements: state variables, events, errors, modifiers, constructor, external, public, internal, private functions - Use custom errors instead of `require` strings (saves gas): `error InsufficientBalance(uint256 available, uint256 required);` …

How to install
mdr add nirholas/three.ws/solidity-best-practices@sha256:7b51e86e02518fcaThe line at the top of this page pins the label git:20260501.87cefc9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
