Guidelines Advisor

Purpose

I will systematically analyze your codebase and provide comprehensive guidance based on Trail of Bits' development guidelines. I'll help you:

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

Framework: Building Secure Contracts - Development Guidelines

How This Works

Phase 1: Discovery & Context

I'll explore 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

I'll help create:

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

Phase 3: Architecture Analysis

I'll analyze:

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

Phase 4: Implementation Review

I'll assess:

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

Phase 5: Recommendations

I'll provide:

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.

Quick Reference:

- Migration vs upgradeability trade-offs
- Data separation patterns
- Upgrade procedure documentation
Delegatecall Proxy Pattern
- Storage layout consistency
- Initialization patterns
- Function shadowing risks
- Slither upgradeability checks
Function Composition
- Function size and clarity
- Logical grouping
- Modularity assessment
Inheritance
- Hierarchy depth/width
- Diamond problem risks
- Inheritance visualization
Events
- Critical operation coverage
- Event naming consistency
- Indexed parameters
Common Pitfalls
- Reentrancy patterns
- Integer overflow/underflow
- Access control issues
- Platform-specific vulnerabilities
Dependencies
- Library quality assessment
- Version management
- Dependency manager usage
- Copied code detection
Testing & Verification
- Coverage analysis
- Fuzzing techniques
- Formal verification
- CI/CD integration
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.

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.

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.

Assessment Process

When invoked, I will:

Explore the codebase
- Identify all contract/module files
- Find existing documentation
- Locate test files
- Check for proxies/upgrades
- Identify dependencies
Generate documentation
- Create plain English system description
- Generate architectural diagrams (if tools available)
- Identify documentation gaps
Analyze architecture
- Assess on-chain/off-chain distribution (if applicable)
- Review upgradeability approach (if applicable)
- Audit proxy patterns (if present)
Review implementation
- Analyze functions, inheritance, events
- Check for common pitfalls
- Assess dependencies
- Evaluate testing
Provide recommendations
- Present findings with file references
- Ask clarifying questions about design decisions
- Suggest prioritized improvements
- Offer actionable next steps

Rationalizations (Do Not Skip)

Rationalization	Why It's Wrong	Required Action
"System is simple, description covers everything"	Plain English descriptions miss security-critical details	Complete all 5 phases: documentation, architecture, implementation, dependencies, recommendations
"No upgrades detected, skip upgradeability section"	Upgradeability can be implicit (ownable patterns, delegatecall)	Search for proxy patterns, delegatecall, storage collisions before declaring N/A
"Not applicable" without verification	Premature scope reduction misses vulnerabilities	Verify with explicit codebase search before skipping any guideline section
"Architecture is straightforward, no analysis needed"	Obvious architectures have subtle trust boundaries	Analyze on-chain/off-chain distribution, access control flow, external dependencies
"Common pitfalls don't apply to this codebase"	Every codebase has common pitfalls	Systematically check all guideline pitfalls with grep/code search
"Tests exist, testing guideline is satisfied"	Test existence ≠ test quality	Check coverage, property-based tests, integration tests, failure cases
"I can provide generic best practices"	Generic advice isn't actionable	Provide project-specific findings with file:line references
"User knows what to improve from findings"	Findings without prioritization = no action plan	Generate prioritized improvement roadmap with specific next steps

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!
