building-patch-tuesday-response-process

building-patch-tuesday-response-process is a skill for Claude Code from 26zl/cybersec-toolkit. It costs 34 tokens per session (2,124 once invoked), scanned A, original, MIT.

A repeatable process for reviewing and deploying Microsoft security updates released on the second Tuesday of each month, known as Patch Tuesday. It covers risk review, testing, rollout, and validation.

In plain words
What is it for?
Review Microsoft security advisories, prioritize affected systems, test updates, deploy them, and confirm that remediation succeeded.
Why use it?
It helps teams handle a large batch of updates in a consistent way while reducing the chance that patches break important systems. Risk-based deadlines keep serious vulnerabilities from being left untreated.

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

building-patch-tuesday-response-process 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 4d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/agent.py, scripts/process.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Building Patch Tuesday Response Process

Overview

Microsoft releases security updates on the second Tuesday of each month ("Patch Tuesday"), addressing vulnerabilities across Windows, Office, Exchange, SQL Server, Azure services, and other products. In 2025, Microsoft patched over 1,129 vulnerabilities across the year -- an 11.9% increase from 2024 -- making a structured response process critical. The leading risk types include elevation of privilege (49%), remote code execution (34%), and information disclosure (7%). This skill covers building a repeatable Patch Tuesday response workflow from initial advisory review through testing, deployment, and validation.

When to Use

  • When deploying or configuring building patch tuesday response process capabilities in your environment
  • When establishing security controls aligned to compliance requirements
  • When building or improving security architecture for this domain
  • When conducting security assessments that require this implementation

Prerequisites

  • Access to Microsoft Security Response Center (MSRC) update guide
  • Vulnerability management platform (Qualys VMDR, Rapid7, Tenable)
  • Patch deployment infrastructure (WSUS, SCCM/MECM, Intune, or third-party)
  • Test environment mirroring production configurations
  • Change management process (ITIL-based or equivalent)
  • Communication channels for cross-team coordination

Changes

What this file has done since we first saw it

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.
