Guidelines Advisor

Guidelines Advisor

Purpose

Systematically analyzes the codebase and provides guidance based on Trail of Bits' development guidelines:

1. Generate documentation and specifications (plain English descriptions, architectural diagrams, code documentation)
2. Optimize on-chain/off-chain architecture (only if applicable)
3. Review upgradeability patterns (if your project has upgrades)
4. Check delegatecall/proxy implementations (if present)
5. Assess implementation quality (functions, inheritance, events)
6. Identify common pitfalls
7. Review dependencies
8. Evaluate test suite and suggest improvements

Framework: Building Secure Contracts - Development Guidelines

How This Works

Phase 1: Discovery & Context

Explores the codebase to understand:

• Project structure and platform
• Contract/module files and their purposes
• Existing documentation
• Architecture patterns (proxies, upgrades, etc.)
• Testing setup
• Dependencies

Phase 2: Documentation Generation

Helps create:

• Plain English system description
• Architectural diagrams (using Slither printers for Solidity)
• Code documentation recommendations (NatSpec for Solidity)

Phase 3: Architecture Analysis

Analyzes:

• On-chain vs off-chain component distribution (if applicable)
• Upgradeability approach (if applicable)
• Delegatecall proxy patterns (if present)

Phase 4: Implementation Review

Assesses:

• Function composition and clarity
• Inheritance structure
• Event logging practices
• Common pitfalls presence
• Dependencies quality
• Testing coverage and techniques

Phase 5: Recommendations

Provides:

• Prioritized improvement suggestions
• Best practice guidance
• Actionable next steps

Assessment Areas

I analyze 11 comprehensive areas covering all aspects of smart contract development. For detailed criteria, best practices, and specific checks, see ASSESSMENT_AREAS.md [blocked].

Quick Reference:

1. Documentation & Specifications

   • Plain English system descriptions
   • Architectural diagrams
   • NatSpec completeness (Solidity)
   • Documentation gaps identification

2. On-Chain vs Off-Chain Computation

   • Complexity analysis
   • Gas optimization opportunities
   • Verification vs computation patterns

3. Upgradeability

   • Migration vs upgradeability trade-offs
   • Data separation patterns
   • Upgrade procedure documentation

4. Delegatecall Proxy Pattern

   • Storage layout consistency
   • Initialization patterns
   • Function shadowing risks
   • Slither upgradeability checks

5. Function Composition

   • Function size and clarity
   • Logical grouping
   • Modularity assessment

6. Inheritance

   • Hierarchy depth/width
   • Diamond problem risks
   • Inheritance visualization

7. Events

   • Critical operation coverage
   • Event naming consistency
   • Indexed parameters

8. Common Pitfalls

   • Reentrancy patterns
   • Integer overflow/underflow
   • Access control issues
   • Platform-specific vulnerabilities

9. Dependencies

   • Library quality assessment
   • Version management
   • Dependency manager usage
   • Copied code detection

10. Testing & Verification

    • Coverage analysis
    • Fuzzing techniques
    • Formal verification
    • CI/CD integration

11. Platform-Specific Guidance

    • Solidity version recommendations
    • Compiler warning checks
    • Inline assembly warnings
    • Platform-specific tools

For complete details on each area including what I'll check, analyze, and recommend, see ASSESSMENT_AREAS.md [blocked].

Example Output

When the analysis is complete, you'll receive comprehensive guidance covering:

• System documentation with plain English descriptions
• Architectural diagrams and documentation gaps
• Architecture analysis (on-chain/off-chain, upgradeability, proxies)
• Implementation review (functions, inheritance, events, pitfalls)
• Dependencies and testing evaluation
• Prioritized recommendations (CRITICAL, HIGH, MEDIUM, LOW)
• Overall assessment and path to production

For a complete example analysis report, see EXAMPLE_REPORT.md [blocked].

Deliverables

I provide four comprehensive deliverable categories:

1. System Documentation

• Plain English descriptions
• Architectural diagrams
• Documentation gaps analysis

2. Architecture Analysis

• On-chain/off-chain assessment
• Upgradeability review
• Proxy pattern security review

3. Implementation Review

• Function composition analysis
• Inheritance assessment
• Events coverage
• Pitfall identification
• Dependencies evaluation
• Testing analysis

4. Prioritized Recommendations

• CRITICAL (address immediately)
• HIGH (address before deployment)
• MEDIUM (address for production quality)
• LOW (nice to have)

For detailed templates and examples of each deliverable, see DELIVERABLES.md [blocked].

Assessment Process

When invoked, I will:

1. Explore the codebase

   • Identify all contract/module files
   • Find existing documentation
   • Locate test files
   • Check for proxies/upgrades
   • Identify dependencies

2. Generate documentation

   • Create plain English system description
   • Generate architectural diagrams (if tools available)
   • Identify documentation gaps

3. Analyze architecture

   • Assess on-chain/off-chain distribution (if applicable)
   • Review upgradeability approach (if applicable)
   • Audit proxy patterns (if present)

4. Review implementation

   • Analyze functions, inheritance, events
   • Check for common pitfalls
   • Assess dependencies
   • Evaluate testing

5. Provide recommendations

   • Present findings with file references
   • Ask clarifying questions about design decisions
   • Suggest prioritized improvements
   • Offer actionable next steps

Rationalizations (Do Not Skip)

Notes

• I'll only analyze relevant sections (won't hallucinate about upgrades if not present)
• I'll adapt to your platform (Solidity, Rust, Cairo, etc.)
• I'll use available tools (Slither, etc.) but work without them if unavailable
• I'll provide file references and line numbers for all findings
• I'll ask questions about design decisions I can't infer from code

Ready to Begin

What I'll need:

• Access to your codebase
• Context about your project goals
• Any existing documentation or specifications
• Information about deployment plans

Let's analyze your codebase and improve it using Trail of Bits' best practices!
