Systematic code maturity assessment using Trail of Bits' 9-category framework. Analyzes codebase for arithmetic safety, auditing practices, access controls, complexity, decentralization, documentation, MEV risks, low-level code, and testing, then produces a scorecard with evidence-based ratings and a priority-ordered roadmap. Use when assessing or scoring the maturity of a smart contract or blockchain codebase, producing a maturity scorecard or evaluation, or judging how mature, well-tested…
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
# 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 ### Phase 3: Report Generates: - Executive summary - Maturity scorecard (ratings for all 9 categories) - Detailed analysis with evidence - Priority-ordered improvement roadmap --- ## Rating System - **Missing (0)**: Not present/not implemented - **Weak (1)**: Several significant improvements needed - **Moderate (2)**: Adequate, can be improved - **Satisfactory (3)**: Above average, minor improvements …

How to install
mdr add trailofbits/skills/code-maturity-assessor@sha256:a5e1427ae04cb0edThe line at the top of this page pins the label git:20260825.32ad9e6, 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.
