# 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](resources/ASSESSMENT_AREAS.md).

### 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

- 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](resources/EXAMPLE_REPORT.md).

## Deliverables

I provide four comprehensive deliverable categories:

### 1. System Documentation
- Plain English descriptions
- Architectural diagrams

### 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](resources/DELIVERABLES.md).

## 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
