Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00088 | $0.02873 |
| Opus 5 | $0.00044 | $0.01437 |
| Sonnet 5 | $0.00018 | $0.00575 |
| Haiku 4.5 | $0.00009 | $0.00287 |
Grade A, and why
configuring-windows-defender-advanced-settings 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 8d 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.
This is a copy
100% identical to configuring-windows-defender-advanced-settings — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Configuring Windows Defender Advanced Settings
When to Use
Use this skill when:
- Configuring Microsoft Defender for Endpoint (MDE) beyond default settings for enhanced protection
- Implementing Attack Surface Reduction (ASR) rules to block common attack techniques
- Enabling controlled folder access for ransomware protection
- Configuring network protection and exploit protection features
- Deploying Defender settings via Intune, SCCM, or Group Policy at enterprise scale
Do not use this skill for third-party EDR deployment (CrowdStrike, SentinelOne) or for Microsoft Defender for Cloud (Azure workload protection).
Prerequisites
- Windows 10/11 Enterprise with Microsoft Defender Antivirus enabled
- Microsoft 365 E5 or Microsoft Defender for Endpoint Plan 2 license (for full MDE features)
- Microsoft Intune or SCCM for enterprise policy deployment
- Microsoft 365 Defender portal access (security.microsoft.com)
- Endpoints not running third-party AV in active mode (Defender enters passive mode)
Workflow
Step 1: Configure Attack Surface Reduction (ASR) Rules
ASR rules block specific behaviors commonly used by malware and attackers:
# Enable ASR rules via PowerShell (or deploy via Intune/GPO)
# Mode: 0=Disabled, 1=Block, 2=Audit, 6=Warn
# Block executable content from email client and webmail

What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
