cx-devassist-kics

cx-devassist-kics is a skill for Claude Code, Codex from Checkmarx/cx-agentic-ai. It costs 208 tokens per session (4,592 once invoked), scanned A, original, Apache-2.0.

A tool for checking Infrastructure as Code files—such as Dockerfiles, Terraform files, and Kubernetes YAML—for unsafe configuration. It can also apply fixes to findings from Checkmarx KICS, a security scanner for these files.

In plain words
What is it for?
Use it to scan or remediate Docker, Terraform, Kubernetes, and similar infrastructure configuration files.
Why use it?
It helps find infrastructure settings that could create security problems before deployment, rather than treating them as ordinary source-code or dependency issues.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cx-devassist-kics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 320 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CX DevAssist KICS

Detects and remediates IaC misconfigurations in Dockerfile, Terraform, Kubernetes YAML, and other Infrastructure-as-Code files using Checkmarx KICS.

When to Use

This skill has two entry points:

  1. On-demand scan — User asks to scan an IaC file for misconfigurations (e.g., "scan this Dockerfile", "check main.tf for issues"). If the target is source code use cx-devassist-asca instead; if it is a dependency manifest/lockfile use cx-devassist-sca instead.
  2. Remediation — User asks to fix KICS findings, or Codex needs to fix IaC misconfigurations detected by KICS.

If KICS findings are already present in context (e.g., provided by a hook block or a prior scan result), skip Flow 1 entirely and proceed directly to Flow 2 using those findings. Do not run the initial scan; Flow 2's re-scan still applies.

Routing — which Checkmarx capability to use

Pick by the target, and ask if it is ambiguous:

The user wants to scan… Use
A source code file (.py, .js, .java, .go, .ts, …) for code vulnerabilities cx-devassist-asca (SAST)
A dependency manifest / lockfile (package.json, requirements.txt, go.mod, pom.xml, …) cx-devassist-sca (SCA/OSS)
An IaC file (Dockerfile, *.tf, *.yaml/*.yml, *.json IaC templates, *.auto.tfvars, *.terraform.tfvars, *.proto) for infrastructure misconfigurations this skill (IaC/KICS)
An entire project / repository at cloud scale, or existing platform scan results the Checkmarx MCP (Cx1 cloud) tools

A bare "scan this file" refers to whatever file is in context: an IaC file → this skill; source code → cx-devassist-asca; a manifest/lockfile → cx-devassist-sca. If it is unclear which, ask the user.

Prerequisites

  • Checkmarx cx CLI installed. On a first-install session cx is in the canonical store but not yet on the agent shell's PATH, so invoke it by its absolute path — "$LOCALAPPDATA/Checkmarx/cx/cx.exe" on Windows, "$HOME/.checkmarx/bin/cx" on Unix (these env vars are available in the agent's shell) — and fall back to a bare cx only when it is already on PATH.
  • Checkmarx MCP server connected (required for remediation)
  • A running container engine (Docker/Podman) — required by the scan itself, see Error Handling below.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
