solidity-coding SKILL.md skillA

solidity-coding from 0xlayerghost/solidity-agent-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add 0xlayerghost/solidity-agent-kit/solidity-coding@git:20261019.4f7b4c6

Pins git:20261019.4f7b4c6 in mdr.lock. Pin the fingerprint instead.

[AUTO-INVOKE] MUST be invoked BEFORE writing or modifying any Solidity contract (.sol files). Covers pragma version, naming conventions, project layout, OpenZeppelin library selection standards, oracle integration, and anti-patterns. Trigger: any task involving creating, editing, or reviewing .sol source files.

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 Coding Standards

## Language Rule

- **Always respond in the same language the user is using.** If the user asks in Chinese, respond in Chinese. If in English, respond in English.

## Coding Principles

- **Compiler**: Use `solc 0.8.24` and `pragma solidity ^0.8.24;` consistently across the project
- **Dependencies**: Use OpenZeppelin Contracts 5.0.2 and its 5.x APIs/import paths; manage imports with the project's Foundry configuration
- **Error Handling**: Prefer custom errors over `require` strings — saves gas and is more expressive
  - Define: `error InsufficientBalance(uint256 available, uint256 required);`
  - Use: `if (balance < amount) revert InsufficientBalance(balance, amount);`
- **Documentation**: All `public` / `external` functions must have NatSpec (`@notice`, `@param`, `@return`)
- **Event Indexing**: Only add `indexed` to `address` type parameters — add comment if indexing other types
- **Special Keywords**: `immutable` / `constant` / `unchecked` / `assembly` must have inline comment explaining why

How to install

The exact contents, by fingerprint
mdr add 0xlayerghost/solidity-agent-kit/solidity-coding@sha256:df290487c2f3d183

The line at the top of this page pins the label git:20261019.4f7b4c6, 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.
