DevOps Detector Skill

Purpose

Detect DevOps tools, CI/CD platforms, containerization, and orchestration from repository signals, job postings, and infrastructure indicators.

Input

Raw signals from Phase 2:

repository_signals - CI/CD configs, Dockerfiles, IaC
job_signals - DevOps job requirements
dns_signals - Service-specific subdomains
http_signals - Deployment patterns

Maturity Assessment

DevOps Maturity Levels:

Basic:
- Manual deployments
- No CI/CD detected
- Minimal automation

Intermediate:
- CI/CD pipeline detected
- Containerization (Docker)
- Basic monitoring

Advanced:
- Full CI/CD with multiple stages
- Container orchestration (K8s)
- Infrastructure as Code
- Comprehensive monitoring

Cloud-Native:
- GitOps practices (ArgoCD)
- Service mesh
- Observability stack
- Multi-cloud or hybrid

Error Handling

Private repositories: Note as limitation
Incomplete config analysis: Provide partial results
Job posting only signals: Lower confidence
