Skills is a Claude Code plugin marketplace from Trail of Bits that provides AI-assisted security analysis capabilities for vulnerability detection and audit workflows.
The marketplace addresses the need to extend Claude's capabilities with specialized security tools by packaging reusable skills that integrate directly into Claude Code and Codex environments. It works by hosting a collection of plugins covering smart contract security, code auditing, and related domains. Users can browse and install plugins through the Claude Code marketplace interface or load the marketplace directly in Codex, which has native support for plugin marketplaces without requiring additional sidecar configuration.
Teams conducting security research, vulnerability assessments, or smart contract audits should consider this marketplace if they want to leverage Claude's code analysis abilities with domain-specific tools. The available plugins include smart contract security toolkits with vulnerability scanners targeting multiple blockchains and development guideline assistants, as well as entry-point analyzers for identifying state-changing functions in contracts. The marketplace is designed for both production use through the Claude Code marketplace and local development workflows, supporting installation in parent directories for testing purposes.
The project maintains active plugin development with multiple specialized security tools available. The marketplace integrates with a broader ecosystem of related configuration and development tools, indicating ongoing investment in supporting Claude-based security workflows across different environments and use cases.
