code-maturity-assessor_skill

Overview

This skill systematically assesses a codebase’s maturity using Trail of Bits’ nine-category framework and produces an evidence-based scorecard with actionable recommendations. It targets arithmetic safety, auditing practices, access controls, complexity, decentralization, documentation, MEV/transaction-ordering risks, low-level code, and testing. The output is a professional report with file-level evidence, ratings, and a prioritized improvement roadmap.

How this skill works

The assessor first discovers project structure, contract/module files, tests, and documentation. It then analyzes each of the nine categories by searching for relevant code patterns, reading key files, and collecting file:line evidence. Finally, it generates an executive summary, a maturity scorecard, detailed per-category findings, and a priority-ordered roadmap with recommended fixes and effort estimates.

When to use it

• Before or after a security audit to benchmark code maturity
• When preparing a codebase for production deployment or funding
• To prioritize remediation work across security and reliability issues
• During periodic security hygiene reviews or CI gating
• When onboarding new engineers to identify architectural risks

Best practices

• Provide full repository access including CI, tests, and docs for accurate assessment
• Answer follow-up questions about deployment, monitoring, and incident processes
• Treat the report as a roadmap: implement CRITICAL items first, then address HIGH and MEDIUM
• Use file:line evidence from the report to create precise tickets and tests
• Integrate recommended checks into CI to prevent regressions

Example use cases

• A smart-contract team preparing for a formal security audit and wanting a pre-audit maturity check
• A product team evaluating whether a codebase meets standards for a grant or investment
• A security lead prioritizing which defects to fix before launch
• An engineering manager measuring progress across documentation, testing, and access controls
• A research team investigating MEV or transaction-ordering risks in their protocol
