explain mode, cache system, expanded analyzers, server & MCP Phase 6 - AI Explain Mode: - Add prompt template system (src/ai/prompts.ts) with language selection - Add text anonymization utilities (src/utils/text.ts) for K8s name masking - Extend AnalysisOptions with explain, backend, language, anonymize flags - Integrate explain flow into analysis engine with cache-check pipeline - Add --explain, --backend, --language, --anonymize, --no-cache CLI flags - Add 9 new AI providers: Azure OpenAI, Cohere, Google Gemini, Vertex AI, Amazon Bedrock, Hugging Face, Groq, IBM watsonx, OCI GenAI Phase 7 - Cache System: - Add CacheProvider interface and FileCacheProvider implementation - Add cache factory with config-driven provider selection - Add cache CLI commands: list, get, remove, purge - Integrate cache into AI explain pipeline with SHA-256 keying Phase 8 - Expanded Coverage: - Add 17 new analyzers: ReplicaSet, StatefulSet, DaemonSet, Job, CronJob, Ingress, ConfigMap, HPA, PDB, NetworkPolicy, Events, Logs, Security, Storage, GatewayClass, Gateway, HTTPRoute - Extend K8s client with Batch, Networking, Autoscaling, Policy, Storage, CustomObjects API accessors - Add HTTP server mode with /health, /analyze, /filters, /config endpoints - Add MCP server with stdio JSON-RPC protocol and 4 analysis tools - Add integration registry with KEDA, Kyverno, Prometheus analyzers - Add custom analyzer framework (command/HTTP execution modes) - Add serve and custom-analyzer CLI commands Tests: 191 passing across 20 test files (58 new tests added) --- src/__tests__/cache.test.ts | 83
