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

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

• 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.

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.

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.

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

```python

# 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.

Model Selection (2025)

• Fast reviews (<200 lines): GPT-4o-mini or Claude 4.5 Haiku
• Deep reasoning: Claude 4.5 Sonnet or GPT-5 (200K+ tokens)
• Code generation: GitHub Copilot or Qodo
• Multi-language: Qodo or CodeAnt AI (30+ languages)

Review Routing

```typescript

interface ReviewRoutingStrategy {

async routeReview(pr: PullRequest): Promise {

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 });

}

}

```

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

1. Anti-patterns:

- Singleton (global state), God objects (>500 lines, >20 methods)

- Anemic models, Shotgun surgery

5. A05 - Security Misconfiguration: Default credentials
6. A06 - Vulnerable Components: Snyk/Dependabot for CVEs
7. A07 - Authentication Failures: Weak session management
8. A08 - Data Integrity Failures: Unsigned JWTs

Scalability Red Flags

• N+1 Queries, Missing Indexes, Synchronous External Calls
• In-Memory State, Unbounded Collections, Missing Pagination
• No Connection Pooling, No Rate Limiting
