Code Maturity Assessor is cataloged under Quality on DirSkills. Code Maturity Assessor comes from a repository tagged agent-skills.

Documentation

README

Code Maturity Assessor

Purpose

Systematically assesses codebase maturity using Trail of Bits' 9-category framework. Provides evidence-based ratings and actionable recommendations.

Framework: Building Secure Contracts - Code Maturity Evaluation v0.1.0

How This Works

Phase 1: Discovery

Explores the codebase to understand:

  • Project structure and platform
  • Contract/module files
  • Test coverage
  • Documentation availability

Phase 2: Analysis

For each of 9 categories, I'll:

  • Search the code for relevant patterns
  • Read key files to assess implementation
  • Present findings with file references
  • Ask clarifying questions about processes I can't see in code
  • Determine rating based on criteria

This is the opening of the README. Read the full README on GitHub.
