Install it, pinned

mdr add gl0bal01/malware-analysis-claude-skills/detection-engineer@git:20260905.e1d9a1a

Create detection rules and hunting queries from malware analysis findings. Use when you need to write Sigma rules for SIEM, Suricata rules for network IDS, defang IOCs for safe sharing, or convert analysis findings into actionable detection content for SOC teams and threat hunters.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Detection Engineer

Transform malware analysis findings into production-ready detection rules, hunting queries, and operationalized IOCs.

> **Note:** YARA rules are authored in the `malware-report-writer` skill, not here. This skill covers Sigma rules, Suricata/Snort rules, and hunting queries.

## Execution Model

- **Start from the evidence, not from the user's memory.** Read `analysis_state.md`, `procmon_summary.txt`, `sysmon_summary.txt`, and the tshark exports yourself; every rule below is derived from a specific observed behavior or network artifact, and you cite it in the rule's `description`/`reference`.
- **Locate skill files.** Scripts and reference files ship in this skill's directory. Set `R="${CLAUDE_PLUGIN_ROOT:-<dir containing this SKILL.md>}"` once (when installed as a plugin `$CLAUDE_PLUGIN_ROOT` is set; otherwise it is this skill folder). Your working directory is the user's analysis workspace, so prefix every script path below with `$R`, e.g. `python3 "$R"/scripts/ioc_extract.py`.

How to install

The exact contents, by fingerprint

mdr add gl0bal01/malware-analysis-claude-skills/detection-engineer@sha256:0d3fb38097c24075

The line at the top of this page pins the label git:20260905.e1d9a1a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
