From e3c11fe0e1fe1ede5f70543af0545cfe92a66b23 Mon Sep 17 00:00:00 2001 From: Tomasz Janiszewski Date: Thu, 2 Apr 2026 16:27:45 +0200 Subject: [PATCH 1/6] ROX-32890: Add MCP prompts for guided vulnerability detection Add MCP prompts infrastructure to guide LLMs in performing comprehensive vulnerability detection workflows. Without prompts, LLMs may only call one tool (e.g., just deployments) missing coverage across orchestrator components, deployments, and nodes. Implement two prompts: - check-vuln: Flexible vulnerability detection with scope-based workflows (fleet/cluster/workloads) supporting single or multiple CVE checks - list-cluster: Simple cluster inventory prompt The prompts provide explicit workflows ensuring consistent, complete vulnerability assessment across all infrastructure layers.

Extract parseArguments into focused helper methods to reduce complexity - Replace interface{} with any for modern Go style - Use fmt.Fprintf instead of WriteString(fmt.Sprintf) for efficiency - Fix function ordering (unexported after exported) - Use switch statements instead of if-else chains - Add required whitespace for readability - Fix line length violations - Rename short variables (sb -> builder, v -> value) Co-Authored-By: Claude Sonnet 4.5 --- internal/prompts/config/list_cluster.go | 2 +- internal/prompts/prompt.go | 2 +- internal/prompts/registry.go | 3 + internal/prompts/vulnerability/check_vuln.go | 407 ++++++++++++------- 4 files changed, 256 insertions(+), 158 deletions(-) diff --git a/internal/prompts/config/list_cluster.go b/internal/prompts/config/list_cluster.go index 827a4da..075956c 100644 --- a/internal/prompts/config/list_cluster.go +++ b/internal/prompts/config/list_cluster.go @@ -30,7 +30,7 @@ func (p *listClusterPrompt) GetPrompt() *mcp.Prompt { } } -func (p *listClusterPrompt) GetMessages(_ map[string]interface{}) ([]*mcp.PromptMessage, error) { +func (p *listClusterPrompt) GetMessages(_ map[string]any) ([]*mcp.PromptMessage, error) { content := `You are helping list all Kubernetes/OpenShift clusters secured by StackRox Central.
