Mahipal 6972fe933e docs(skills): rewrite container-security descriptions to a uniform standard
All 33 container-security skills now carry what it does, an explicit
"Use when" trigger, keywords, and a negative trigger naming the nearest
neighbour. Six collision clusters resolved by differentiating scope
rather than merging, so no skill is removed:

- kube-bench: running the tool vs interpreting findings into an audit
- Calico: portable upstream NetworkPolicy vs Calico-as-CNI vs Calico-only
  CRDs (GlobalNetworkPolicy, HostEndpoint, DNS egress)
- Falco: deploying and operating it vs authoring escape rules
- container escape: tool-agnostic runtime signals vs Falco rule syntax vs
  static posture audit vs offensive breakout
- Trivy: all-target platform and operator vs single-image scan
- Docker: images and Dockerfiles vs daemon.json vs the CIS audit script

Also replaces the templated "When to Use" boilerplate in these files,
including bullets that only restated the skill's own name.

Worst pair (Pod Security Standards vs Pod Security Admission) drops from
0.77 cosine to below the 0.45 threshold. Repo-wide: colliding pairs
60 -> 56, skills involved 105 -> 94.

Performing Container Security Scanning with Trivy

Overview

Trivy is an open-source security scanner by Aqua Security that detects vulnerabilities in OS packages and language-specific dependencies, infrastructure-as-code misconfigurations, exposed secrets, and software license issues across container images, filesystems, Git repositories, and Kubernetes clusters. Trivy generates Software Bill of Materials (SBOM) in CycloneDX and SPDX formats for supply chain transparency. This skill covers comprehensive container image scanning, CI/CD pipeline integration, Kubernetes operator deployment, and scan result triage for security operations.

When to Use

  • When conducting security assessments that involve performing container security scanning with trivy
  • When following incident response procedures for related security events
  • When performing scheduled security testing or auditing activities
  • When validating security controls through hands-on testing

Prerequisites

  • Trivy v0.50+ installed (binary, Docker, or Homebrew)
  • Docker daemon access for local image scanning
  • Container registry credentials for remote image scanning
  • CI/CD platform (GitHub Actions, GitLab CI, Jenkins) for pipeline integration
  • Kubernetes cluster for Trivy Operator deployment (optional)

Steps

Step 1: Scan Container Images

Run vulnerability and secret scanning against container images from local builds or remote registries. Configure severity thresholds and ignore unfixed vulnerabilities.

Step 2: Generate SBOM

Produce CycloneDX or SPDX SBOM documents from scanned images for supply chain compliance and vulnerability tracking across the software lifecycle.

Step 3: Scan IaC and Kubernetes Manifests

Detect misconfigurations in Dockerfiles, Kubernetes YAML, Terraform, and Helm charts using built-in policy checks aligned with CIS benchmarks.

Step 4: Integrate into CI/CD

Add Trivy scanning as a pipeline gate that blocks builds with critical/high vulnerabilities, generates SARIF reports for GitHub Advanced Security, and produces JUnit XML for test dashboards.

Expected Output

JSON/table report listing CVEs with severity, CVSS scores, fixed versions, affected packages, misconfiguration findings, and exposed secrets with file locations.
