• Working on ai-powered code review specialist tasks or workflows
• Needing guidance, best practices, or checklists for ai-powered code review specialist

Do not use this skill when

• The task is unrelated to ai-powered code review specialist
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.

Context

Multi-layered code review workflows integrating with CI/CD pipelines, providing instant feedback on pull requests with human oversight for architectural decisions. Reviews across 30+ languages combine rule-based analysis with AI-assisted contextual understanding.

Requirements

Review: $ARGUMENTS

Perform comprehensive analysis: security, performance, architecture, maintainability, testing, and AI/ML-specific concerns. Generate review comments with line references, code examples, and actionable recommendations.

Automated Code Review Workflow

Initial Triage

1. Parse diff to determine modified files and affected components
2. Match file types to optimal static analysis tools
3. Scale analysis based on PR size (superficial >1000 lines, deep <200 lines)
4. Classify change type: feature, bug fix, refactoring, or breaking change

Multi-Tool Static Analysis

Execute in parallel:

• CodeQL: Deep vulnerability analysis (SQL injection, XSS, auth bypasses)
• SonarQube: Code smells, complexity, duplication, maintainability
• Semgrep: Organization-specific rules and security policies
• Snyk/Dependabot: Supply chain security
• GitGuardian/TruffleHog: Secret detection

AI-Assisted Review

# Context-aware review prompt for Claude 4.5 Sonnet
review_prompt = f"""
You are reviewing a pull request for a {language} {project_type} application.

**Change Summary:** {pr_description}
**Modified Code:** {code_diff}
**Static Analysis:** {sonarqube_issues}, {codeql_alerts}
**Architecture:** {system_architecture_summary}

Focus on:
1. Security vulnerabilities missed by static tools
2. Performance implications at scale
3. Edge cases and error handling gaps
4. API contract compatibility
5. Testability and missing coverage
6. Architectural alignment

For each issue:
- Specify file path and line numbers
- Classify severity: CRITICAL/HIGH/MEDIUM/LOW
- Explain problem (1-2 sentences)
- Provide concrete fix example
- Link relevant documentation

Format as JSON array.

Review Routing

interface ReviewRoutingStrategy {
  async routeReview(pr: PullRequest): Promise<ReviewEngine> {
    const metrics = await this.analyzePRComplexity(pr);

    if (metrics.filesChanged > 50 || metrics.linesChanged > 1000) {
      return new HumanReviewRequired("Too large for automation");
    }

    if (metrics.securitySensitive || metrics.affectsAuth) {
      return new AIEngine("claude-3.7-sonnet", {
        temperature: 0.1,
        maxTokens: 4000,
        systemPrompt: SECURITY_FOCUSED_PROMPT
      });
    }

    if (metrics.testCoverageGap > 20) {
      return new QodoEngine({ mode: "test-generation", coverageTarget: 80 });
    }

    return new AIEngine("gpt-4o", { temperature: 0.3, maxTokens: 2000 });
  }
}

Architecture Analysis

Architectural Coherence

1. Dependency Direction: Inner layers don't depend on outer layers
2. SOLID Principles:
   • Single Responsibility, Open/Closed, Liskov Substitution
   • Interface Segregation, Dependency Inversion
3. Anti-patterns:
   • Singleton (global state), God objects (>500 lines, >20 methods)
   • Anemic models, Shotgun surgery
