Spring Lens is an AI Runtime Operating System for Spring Boot applications.

It does not treat logs as the primary diagnostic surface. Instead, it captures runtime behavior as structured execution graphs and exposes question-oriented runtime tools for AI systems.

• spring-lens-model
• shared runtime graph model and registration DTOs
• spring-lens-spi
• plugin contracts for collectors, tools, and playbooks
• spring-lens-runtime
• in-memory graph assembly and built-in collectors for HTTP, exception, and JDBC slow SQL
• spring-lens-starter
• default low-risk Spring Boot starter with observation-native capture foundations, runtime query API, and compatibility instrumentation switches
• spring-lens-agent-contract
• shared agent-side contracts for overlay specs, patch proposals, and instrumentation modes
• spring-lens-agent-starter
• explicit high-trust extension for agent-origin instrumentation and future overlay/patch control
• spring-lens-server
• external control plane with application registry, tool registry/router, playbooks, and MCP-exposed tools
• spring-lens-demo-app
• runnable example application backed by H2

• Add spring-lens-starter when you want runtime truth, execution graphs, and AI-facing runtime tools with the lowest adoption risk.
• Add spring-lens-agent-starter only when you want to opt into future high-trust agent instrumentation flows such as overlays or governed source patch proposals.

Current Phase 1 defaults:

• spring.lens.observation-native-enabled=true
• spring.lens.compatibility-instrumentation-enabled=true

This means the observation-native path is present and testable, while l
