solidity-security SKILL.md skillA
solidity-security from dicklesworthstone/pi_agent_rust is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dicklesworthstone/pi_agent_rust/solidity-security@git:20260205.788be98Pins git:20260205.788be98 in mdr.lock. Pin the fingerprint instead.

Master smart contract security best practices to prevent common vulnerabilities and implement secure Solidity patterns. Use when writing smart contracts, auditing existing contracts, or implementing security measures for blockchain applications.
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
Master smart contract security best practices, vulnerability prevention, and secure Solidity development patterns.
## When to Use This Skill
- Writing secure smart contracts
- Auditing existing contracts for vulnerabilities
- Implementing secure DeFi protocols
- Preventing reentrancy, overflow, and access control issues
- Optimizing gas usage while maintaining security
- Preparing contracts for professional audits
- Understanding common attack vectors
## Critical Vulnerabilities
### 1. Reentrancy
Attacker calls back into your contract before state is updated.
**Vulnerable Code:**
```solidity
// VULNERABLE TO REENTRANCY
contract VulnerableBank {
mapping(address => uint256) public balances;
function withdraw() public {
uint256 amount = balances[msg.sender];
// DANGER: External call before state update
(bool success, ) = msg.sender.call{value: amount}("");
require(success);
balances[msg.sender] = 0; // Too late!
}
}
```
**Secure Pattern (Checks-Effects-Interactions):**
```solidity
contract SecureBank {
mapping(address => uint256) public balances;
function withdraw() public {

How to install
mdr add dicklesworthstone/pi_agent_rust/solidity-security@sha256:57c4e951a20c847bThe line at the top of this page pins the label git:20260205.788be98, 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.
