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

[AUTO-INVOKE] MUST be invoked BEFORE writing or modifying any Solidity contract (.sol files). Covers private key handling, access control, reentrancy prevention, gas safety, and pre-audit checklists. 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 Security 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. ## Private Key Protection - Before an on-chain write, let the developer choose a signing method: - **Foundry Keystore (recommended):** import with `cast wallet import <NAME> --interactive` and use `--account <NAME>`. - **Environment file:** store `PRIVATE_KEY` in `.env`, load it with `source .env`, and reference `"$PRIVATE_KEY"`; never paste the literal value into a command. - Never expose private keys in logs, screenshots, conversations, or commits - Provide `.env.example` with placeholder values for team reference - Add `.env` to `.gitignore` — verify with `git status` before every commit - Never read or print a developer's `.env`; only provide commands for the developer to run ## Security Decision Rules When writing or reviewing Solidity code, apply these rules: | Situation | Required Action | |-----------|----------------| | External ETH/token transfer | Use `ReentrancyGuard` + Checks-Effects-Interactions (CEI) pattern | …

How to install
mdr add 0xlayerghost/solidity-agent-kit/solidity-security@sha256:d1fc412e317efd98The 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.
