Solidity Developer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Solidity development guide with minor packaging and dependency-hygiene cautions, not evidence of malicious behavior.

Before installing, be aware that activation metadata should be fixed to explicit triggers, and prefer project-local or pinned Hardhat/Foundry dependencies when running validation commands. Do not use the skill to deploy to mainnet without reviewing generated contracts, tests, deployment parameters, and wallet/RPC handling yourself.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Confidence
96% confidence
Finding
The trigger definition is effectively unspecified (`System.Object[]`), so the skill lacks clear activation phrases or constraints. This can cause the platform or downstream tooling to invoke the skill too broadly or unpredictably, increasing the chance of unintended execution in contexts where smart-contract development actions are not appropriate.

Finding
npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.
