Use to close the Offensive Vaccine loop on the defender side. The Detector agent produces Sigma / YARA rules from offensive operations; this catalog validates those rules against real memory dumps, event logs, and forensic artifacts using Volatility 3, plaso, and sigma-cli. Without this catalog, detection rules are theoretical.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'dfir-overview' ] || [ -L ~/.agents/skills/'dfir-overview' ]; then echo 'A skill folder named dfir-overview already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/BitterSecurity/Decepticon' "$d" && git -C "$d" checkout --quiet 'bdb1016c93ed687f61ac57481da298c25a47c8f5' -- 'packages/decepticon/decepticon/skills/standard/dfir' && mkdir -p ~/.agents/skills && cp -R "$d"/'packages/decepticon/decepticon/skills/standard/dfir' ~/.agents/skills/'dfir-overview' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'dfir-overview' ~/.claude/skills/'dfir-overview' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
