USE FOR

• "review Java Azure SDK sample"
• "check Java sample for best practices"
• "Azure SDK Java code review"
• Reviewing credential handling in Azure SDK Java samples
• Error pattern analysis for Java Azure SDK samples
• Documentation compliance check for Java Azure SDK samples
• Spring Boot integration review for Azure SDK Java samples

DO NOT USE FOR

• General Java code review unrelated to Azure SDK samples
• Production application code review
• Azure service configuration

Context

Base template: Inherits from azure-sdk-sample-review for shared review patterns (credentials, error handling, documentation, infrastructure). This skill adds Java-specific rules below.

Use this skill when reviewing Java code samples for Azure SDKsintended for publication as Microsoft Azure samples. Focuses on:

• Azure SDK client patterns (Track 2 com.azure.*, client builders, pipeline policies)
• Authentication (DefaultAzureCredential, managed identities, token management)
• Service-specific best practices (Cosmos DB, SQL, Storage, Service Bus, Key Vault, AI services)
• Sample hygiene (credentials, build artifacts, dependency audit, .gitignore)
• Documentation accuracy (README output, troubleshooting, setup instructions)
• Infrastructure-as-code (Bicep/Terraform with AVM modules)
• azd integration (azure.yaml structure, hooks, service definitions)
• Spring Boot / Spring Cloud Azure integration patterns

---

Quick Pre-Review Checklist (5-Minute Scan)

• pom.xml / build.gradle: Uses Track 2 Azure SDK packages (com.azure:*, not com.microsoft.azure:*)
• Authentication: Uses DefaultAzureCredential (not connection strings or hardcoded keys)
• .gitignore: Exists and includes .env, target/, build/, *.class, .idea/
• No secrets: No hardcoded credentials, API keys, or tokens in code
• README.md: Exists with prerequisites, setup steps, and expected output
• LICENSE: MIT license file present (required for Azure Samples)
• Security: No known critical/high CVEs in dependency tree
• Java version: Uses Java 17 or 21 LTS
• Error handling: catch blocks present with proper exception hierarchy
• Resource cleanup: Clients properly closed (try-with-resources or finally blocks)
• BOM: Uses azure-sdk-bom for version management
• No mixed build tools: Only Maven OR Gradle (not both)
• Imports work: No broken imports, all dependencies declared
• Build succeeds: mvn compile or gradle build completes without errors
• Sample runs: mvn exec:java or java -jar executes without crashes

Blocker Issues (Auto-Reject)

These issues always block publication. Samples with any of these must be rejected immediately:

1. Hardcoded secrets—Any production credentials, API keys, connection strings, or tokens in code
2. Missing authentication—No auth implementation or uses insecure methods
3. No error handling—Unchecked exceptions, no try/catch blocks, silent failures
4. Broken imports—Missing dependencies, incorrect package names, class not found errors
5. Security vulnerabilities—mvn dependency-check:check or Dependabot shows critical/high CVEs
6. Missing LICENSE—No LICENSE file at ANY level of repo hierarchy (MIT required). ⚠️ Check repo root before flagging.
7. .env file committed—Live credentials in version control. ⚠️ Verify with git ls-files .env—a .env on disk but in .gitignore is NOT committed.
8. Track 1 packages—Uses legacy com.microsoft.azure:* packages instead of com.azure:*

Severity Legend

• CRITICAL: Security vulnerability or sample will not run. Must fix before any publication.
• HIGH: Major quality issue that will confuse users or cause production failures. Fix before merge.
• MEDIUM: Best practice violation. Should fix before publication for maintainability.
• LOW: Polish item, nice-to-have improvement.
