What is Defender Scout KQL?

A KQL assistant for Microsoft Defender Advanced Hunting, where KQL is the query language used to search security data. It works across endpoint, identity, email, cloud-app, and other Defender data.

Use it to write or optimize threat-hunting queries, investigate alerts and incidents, inspect devices and network activity, and find suspicious processes, identities, email, or vulnerabilities.

It helps security teams create, check, explain, and speed up queries used to investigate threats and Microsoft 365 security data.

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.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00039	$0.01278
Opus 5.5	$0.00016	$0.00511
Sonnet 5.5	$0.00008	$0.00256
Haiku 4.5	$0.00004	$0.00128

Security

Grade A, and why

Defender Scout KQL 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 2mo 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.

Generate production-ready KQL queries based on user descriptions:

Security threat hunting queries
Device inventory and asset management
Alert and incident analysis
Email security investigation
Identity-based attack detection
Vulnerability assessment
Network connection analysis
Process execution monitoring

2. Query Validation

Check KQL queries for:

Syntax errors and typos
Performance issues
Inefficient operations
Missing time filters
Potential data inconsistencies

3. Query Optimization

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.
