Spring Boot Scanner

Smart pattern detection and skill routing for Spring Boot projects.

Core Behavior

Trigger Conditions:

• Editing *.java or *.kt files in a project with spring-boot-starter dependencies
• Working with pom.xml or build.gradle* containing Spring Boot
• User mentions "Spring Boot", "Spring Security", "Spring Data", etc.

Action: Scan code → Detect patterns → Route to appropriate skill

Detection Algorithm

Scans in 3 phases: (1) detect Spring Boot project via build files, (2) scan annotations against the map below, (3) route by risk level — LOW auto-invokes, HIGH confirms first. See WORKFLOW.md for the full step-by-step detection flow.

Annotation → Skill Map

Use this script to detect patterns:

# Run from project root
python3 scripts/detect_patterns.py /path/to/file.java

Or use Grep directly:

# Web API detection
grep -l "@RestController\|@GetMapping\|@PostMapping" **/*.java

# Security detection
grep -l "@EnableWebSecurity\|@PreAuthorize\|SecurityFilterChain" **/*.java

# Testing detection
grep -l "@SpringBootTest\|@WebMvcTest\|@MockitoBean\|@MockBean" **/*.java

Escalation Triggers

Always confirm before proceeding when detecting:

Integration with Existing Components

Delegates to Skills:

• spring-boot-web-api → REST patterns
• spring-boot-data-ddd → Repository/Entity patterns
• spring-boot-security → Security configuration
• spring-boot-testing → Test patterns
• spring-boot-modulith → Module structure
• spring-boot-observability → Metrics/Health
• spring-boot-verify → Dependencies/Config
• domain-driven-design → DDD architecture

Delegates to Agents (for comprehensive review):

• spring-boot-reviewer → Full codebase review
• spring-boot-upgrade-verifier → Migration analysis

When to delegate to agents:

• User asks for "review" or "scan" of entire project
• Multiple HIGH RISK patterns across many files
• Explicit /spring-review or /verify-upgrade command

Known Limitations

• Annotation-based only: Detects standard Spring annotations, not custom/meta-annotations or XML configuration
• Java and Kotlin only: Scans *.java and *.kt files; no Groovy/Scala support
• Spring Boot 3.x+ optimized: Escalation patterns focus on Boot 3.x → 4.x migration; older versions may have gaps
• No AST parsing: Uses regex matching, so patterns in comments/strings may cause false positives

Escape Hatch

If scanner guidance isn't helpful for the current context:

The scanner is advisory—it suggests skills but never blocks the workflow.

Critical Reminders

1. Always check project type first — Only activate for Spring Boot projects
2. Respect risk levels — Never auto-invoke security/testing/verify without confirmation
3. Batch notifications — Don't spam user with multiple skill suggestions
4. Delegate to agents for scale — Use reviewer agent for multi-file analysis
5. Preserve user flow — Guidance should assist, not interrupt
