🧩 spring-boot Γ— browser-extension

Ship browser extension on Spring Boot with sensible defaults.

Spring Boot is a Java workable choice for browser extension. GreatCTO auto-detects both β€” adds the browser-extension archetype overlay, wires browser-extension-specific gates, and runs 83 specialist agents around your existing Spring Boot workflow.

What changes when GreatCTO joins your Spring Boot project

Detection β†’ overlay β†’ gates β†’ reviewers.

1 Β· DETECT

Stack + archetype

GreatCTO reads your pom.xml / build.gradle and detects spring-boot + browser-extension archetype from signals: imports, file structure, env vars, README hints.

2 Β· OVERLAY

Archetype pack

Attaches the browser-extension archetype overlay: archetype-specific reviewer + compliance gates. Override if your specifics differ; the defaults are sensible for Spring Boot-style projects.

3 Β· GATES

Spring Boot-aware reviewers

qa-engineer runs ./gradlew check / SpotBugs / JaCoCo coverage; security-officer scans for deserialization sinks + Spring SpEL injection; performance-engineer profiles JVM + GC patterns.

4 Β· MEMORY

Cross-project lessons

Bugs you've hit before in other Spring Boot projects (connection-pool exhaustion, ORM N+1 queries, retry storms) β€” the agent's Step 0 includes the prior detection order. MTTR drops 94 % on second occurrence (methodology).

⚐ gate:plan β€” your approval needed

Approve β†’ 3 senior-devs run in parallel worktrees β†’ 5 reviewers fan out in parallel β†’ gate:ship β†’ deploy. One real run walked stage-by-stage: /proof.

What ships

The first feature, Spring Boot-idiomatic.

This is the shape of what senior-dev drafts for "browser-extension feature" β€” auth first, schema validation, and the audit line the browser-extension reviewer requires before gate:ship opens.

// src/main/java/.../BrowserExtensionController.java β€” reviewed by 5 agents
@RestController
@RequestMapping("/browser-extension")
class BrowserExtensionController {
  @PostMapping
  @PreAuthorize("isAuthenticated()")          // security-officer: auth before handler
  ResponseEntity<Result> create(@Valid @RequestBody BrowserExtensionRequest req,
                                Principal user) {
    var result = service.handle(req, user);   // qa-engineer: bean validation enforced
    audit.log(user.getName(), "browser-extension feature", result.confidence()); // gate:browser-extension
    return ResponseEntity.ok(result);
  }
}
Where this combo lands

What teams build with Spring Boot + the browser-extension overlay.

1

Productivity extensions with minimal host permissions.

2

Enterprise extensions passing Chrome Web Store review.

3

Cross-browser extensions (Chrome / Firefox / Safari).

⚠ Honest caveat

Spring Boot (Java) is not a typical fit for browser extension. The archetype overlay still attaches, but you may want to override defaults more aggressively. Check the browser-extension archetype page for the typical stack list and decide if your case is the right tool / right archetype.

Architecture

Every step of the pipeline, transparent.

No black-box "AI does it all" loop. GreatCTO is a deterministic state machine β€” 8 stages, 22 nodes, 2 human gates. Every node maps to a real agent on GitHub. Inspect the state machine β†’

Install

Spring Boot + GreatCTO in one command.

$ npx great-cto init

Free, MIT, runs locally. Built as a Claude Code plugin β€” install with one command.
