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. Produces professional scorecard with evidence-based ratings and actionable recommendations.

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
Explores the codebase to understand:
For each of 9 categories, I'll:

Rating Logic:
I assess 9 comprehensive categories covering all aspects of code maturity. For detailed criteria, analysis approaches, and rating thresholds, see ASSESSMENT_CRITERIA.md.
1. ARITHMETIC
2. AUDITING
3. AUTHENTICATION / ACCESS CONTROLS
4. COMPLEXITY MANAGEMENT
5. DECENTRALIZATION
6. DOCUMENTATION
7. TRANSACTION ORDERING RISKS
8. LOW-LEVEL MANIPULATION
9. TESTING & VERIFICATION
For complete assessment criteria including what I'll analyze, what I'll ask you, and detailed rating thresholds (WEAK/MODERATE/SATISFACTORY/STRONG), see ASSESSMENT_CRITERIA.md.
When the assessment is complete, you'll receive a comprehensive maturity report including:
For a complete example assessment report, see EXAMPLE_REPORT.md.

Generate report
| Rationalization | Why It's Wrong | Required Action |
|---|---|---|
| "Found some findings, assessment complete" | Assessment requires evaluating ALL 9 categories | Complete assessment of all 9 categories with evidence for each |
| "I see events, auditing category looks good" | Events alone don't equal auditing maturity | Check logging comprehensiveness, testing, incident response processes |
| "Code looks simple, complexity is low" | Visual simplicity masks composition complexity | Analyze cyclomatic complexity, dependency depth, state machine transitions |
| "Not a DeFi protocol, MEV category doesn't apply" | MEV extends beyond DeFi (governance, NFTs, games) | Verify with transaction ordering analysis before declaring N/A |
| "No assembly found, low-level category is N/A" | Low-level risks include external calls, delegatecall, inline assembly | Search for all low-level patterns before skipping category |
| "This is taking too long" | Thorough assessment requires time per category | Complete all 9 categories, ask clarifying questions about off-chain processes |
| "I can rate this without evidence" | Ratings without file:line references = unsubstantiated claims | Collect concrete code evidence for every category assessment |
| "User will know what to improve" | Vague guidance = no action | Provide priority-ordered roadmap with specific improvements and effort estimates |
For detailed report structure and templates, see REPORT_FORMAT.md.

Let's assess this codebase!
Audits GitHub Actions workflows for security vulnerabilities in AI agent integrations including Claude Code Action, Gemini CLI, OpenAI Codex, and GitHub AI Inference. Detects attack vectors where attacker-controlled input reaches AI agents running in CI/CD pipelines, including env var intermediary patterns, direct expression injection, dangerous sandbox configurations, and wildcard user allowlists. Use when reviewing workflow files that invoke AI coding agents, auditing CI/CD pipeline security for prompt injection risks, or evaluating agentic action configurations.
Clarify requirements before implementing. Use when serious doubts arise.
Enables ultra-granular, line-by-line code analysis to build deep architectural context before vulnerability or bug finding.
Scans Algorand smart contracts for 11 common vulnerabilities including rekeying attacks, unchecked transaction fees, missing field validations, and access control issues. Use when auditing Algorand projects (TEAL/PyTeal).
Prepares codebases for security review using Trail of Bits' checklist. Helps set review goals, runs static analysis tools, increases test coverage, removes dead code, ensures accessibility, and generates documentation (flowcharts, user stories, inline comments).
Scans Cairo/StarkNet smart contracts for 6 critical vulnerabilities including felt252 arithmetic overflow, L1-L2 messaging issues, address conversion problems, and signature replay. Use when auditing StarkNet projects.
