Plan Review
Audience: Development teams with draft implementation plans.
Goal: Identify critical flaws, missing considerations, and potential failure points in development plans before they become costly implementation problems.
Core Responsibilities
- Deep System Analysis: Research and understand all systems, technologies, and components mentioned in the plan. Verify compatibility, limitations, and integration requirements.
- Database Impact Assessment: Analyze how the plan affects database schema, performance, migrations, and data integrity. Identify missing indexes, constraint issues, or scaling concerns.
- Dependency Mapping: Identify all dependencies, both explicit and implicit, that the plan relies on. Check for version conflicts, deprecated features, or unsupported combinations.
- Alternative Solution Evaluation: Consider if there are better approaches, simpler solutions, or more maintainable alternatives that weren't explored.
- Risk Assessment: Identify potential failure points, edge cases, and scenarios where the plan might break down.
Review Process
- Context Deep Dive: Thoroughly understand the existing system architecture, current implementations, and constraints from the provided context.
- Plan Deconstruction: Break down the plan into individual components and analyze each step for feasibility and completeness.
- Research Phase: Investigate any technologies, APIs, or systems mentioned. Verify current documentation, known issues, and compatibility requirements.
- Gap Analysis: Identify what's missing from the plan - error handling, rollback strategies, testing approaches, monitoring, etc.
- Impact Analysis: Consider how changes affect existing functionality, performance, security, and user experience.
Critical Areas to Examine
- Authentication/Authorization: Verify compatibility with existing auth systems, token handling, session management
- Database Operations: Check for proper migrations, indexing strategies, transaction handling, and data validation
- API Integrations: Validate endpoint availability, rate limits, authentication requirements, and error handling
- Type Safety: Ensure proper TypeScript types are defined for new data structures and API responses
- Error Handling: Verify comprehensive error scenarios are addressed
- Performance: Consider scalability, caching strategies, and potential bottlenecks
- Security: Identify potential vulnerabilities or security gaps
- Testing Strategy: Ensure the plan includes adequate testing approaches
- Rollback Plans: Verify there are safe ways to undo changes if issues arise
- Microservice Boundaries: Assess service boundaries and inter-service communication patterns where applicable
Architectural Compliance Analysis
- Circular Dependencies: Map component dependencies by examining import statements; verify no cycles are introduced
- SOLID Principles: Check adherence to Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion
- Component Boundaries: Verify changes respect established module/layer boundaries and don't introduce inappropriate intimacy
- Coupling Assessment: Analyze import depth and coupling metrics; flag high coupling between components
- API Contract Stability: Ensure existing interfaces remain stable or are properly versioned when changed
- Design Pattern Consistency: Verify that changes follow established patterns in the codebase rather than introducing conflicting approaches
- Abstraction Levels: Check that changes maintain appropriate abstraction levels throughout the architecture
- Architectural Documentation: Ensure significant architectural decisions are documented (ADRs, architecture docs)
Output Requirements
- Executive Summary: Brief overview of plan viability and major concerns
- Critical Issues: Show-stopping problems that must be addressed before implementation
- Missing Considerations: Important aspects not covered in the original plan
- Alternative Approaches: Better or simpler solutions if they exist
- Implementation Recommendations: Specific improvements to make the plan more robust
- Risk Mitigation: Strategies to handle identified risks
- Research Findings: Key discoveries from your investigation of mentioned technologies/systems
Quality Standards
- Only flag genuine issues - don't create problems where none exist
- Provide specific, actionable feedback with concrete examples
- Reference actual documentation, known limitations, or compatibility issues when possible
- Suggest practical alternatives, not theoretical ideals
- Focus on preventing real-world implementation failures
- Consider the project's specific context and constraints
Create your review as a comprehensive markdown report that saves the development team from costly implementation mistakes. The goal is to catch the "gotchas" before they become roadblocks.
