cx-install-wiring

cx-install-wiring is a skill for Claude Code, Cursor from Checkmarx/cx-agentic-ai. It costs 69 tokens per session (1,280 once invoked), scanned B, original, Apache-2.0.

An on-demand setup workflow for Checkmarx DevAssist in Cursor's command-line tool. It connects the required hooks and rules, then continues with Checkmarx CLI installation and sign-in.

In plain words
What is it for?
Use it to wire Checkmarx hooks and rules, install the Checkmarx command-line tool, and authenticate it when `/cx-install-wiring` is invoked.
Why use it?
It guides first-time setup when the developer explicitly runs the command, reducing uncertainty about the order of installation and configuration steps.

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 B, and why

cx-install-wiring scanned grade B with 1 finding 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 9d 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.

Tells the agent never to refusemediumAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

description: "On-demand first-time Checkmarx DevAssist setup (intended for Cursor CLI): wires hooks and rules, then continues into cx CLI install and auth. When the developer types /cx-install-wiring, always run the work

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CX Install Wiring (on demand — intended for Cursor CLI)

On-demand only — runs when the developer explicitly types /cx-install-wiring. Do not auto-invoke this skill from hook denies or missing cx.

If /cx-install-wiring was invoked — always run Phase 1

There is no reliable environment signal to tell Cursor CLI from the IDE Agent panel. When the developer typed /cx-install-wiring, proceed immediately with Phase 1 (scope → install-hooks.sh).

Forbidden:

  • Refusing with "this skill runs only from Cursor CLI" or telling them to open a terminal / run agent / type /cx-install-wiring again — unless they explicitly say they are in the IDE chat panel and cannot use the Shell tool.
  • Guessing that the session is IDE based on workspace paths, Windows paths, or chat UI alone.

Documentation note (not a gate): This flow is designed for Cursor CLI (terminal agent). IDE users who need hooks should run install-hooks.sh manually (see README) or use /cx-cli-setup for cx only — but do not block a slash-command invocation on that assumption.

Never tell the developer to use Developer: Reload Window, the Command Palette, or IDE MCP settings — those apply to the IDE, not Cursor CLI.

Then wire hooks and rules and automatically continue into cx install/auth via skills/cx-cli-setup/SKILL.md — do not ask the developer to run /cx-cli-setup separately.

Do not run Get-Command cx, cx auth validate, or any other cx command in this phase.

Scope

Question 1 — ask once:

"Install Checkmarx hooks and rules for: (1) User — all projects (~/.cursor/), or (2) Project — one specific repo (<repo>/.cursor/)?"

  • User → run install-hooks.sh with no extra env vars (see below).
  • Project → ask Question 2 before running the installer. Do not assume "this repo" without the developer's choice.

Question 2 — only when they chose Project:

"Which repo should get project-scoped hooks and rules? (A) This repo — the directory you're in now (<show resolved absolute path>) (B) Another path — reply with the absolute path to that repo's root."
