What does the Niklas skill do?

Engineer detections: Sigma/KQL/SPL, ATT&CK coverage, testing and false-positive tuning. Load it once into Claude Projects and you get a configured Detection Engineer without re-explaining context at the start of every session. Defensive security only. Always operate within authorized scope and your organization's rules of engagement, validate detections and controls in a lab or non-production environment first, and follow change control before touching production systems.

How do I install this skill file?

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Niklas skill?

Without a skill file your AI starts every session as a general assistant. With Niklas loaded it applies Detection Engineer methodology from the first message, with consistent quality every time. Defensive security only. Always operate within authorized scope and your organization's rules of engagement, validate detections and controls in a lab or non-production environment first, and follow change control before touching production systems.

// what's inside

Drop Niklas into Claude and get a detection engineer who writes Sigma and SIEM detections that catch the technique, map to ATT&CK, and don't drown you in false positives.

Niklas engineers detections: detection-as-code (Sigma rules, SIEM content in KQL and SPL), MITRE ATT&CK coverage and gap analysis, data-source and telemetry requirements, detection testing and validation (atomic test concepts), tuning to cut false positives and alert fatigue, alert enrichment and fidelity, and detection versioning in CI. Defensive only. Test and tune in a lab before production monitoring.

# Niklas — Detection Engineer

You are Niklas, a detection engineer. You write Sigma and SIEM detections that catch the technique, map to ATT&CK, and don't drown you in false positives. Defensive only.

## How you work
1. Pick the technique; check ATT&CK coverage and data sources
2. Write the detection as code (Sigma, KQL, SPL)
3. Test and validate; tune out false positives
4. Version in CI; deploy to production monitoring after lab testing

Defensive only: test and tune in a lab before production, and version detections as code.

Excerpt from the actual file you'll download.

// try it

prompt

$Write a detection for a suspicious-PowerShell technique, map it to ATT&CK, and tune out the false positives.

Niklas returns the Sigma rule and its KQL and SPL, the data-source requirements, the ATT&CK mapping, a test/validation plan, and the false-positive tuning, defensive and lab-tested before production.
