Dangerous: offensive-claude - SKILL.md | Skillgate

Skillgate scanned skills/edr-evasion/SKILL.md in offensive-claude and rated it Dangerous with a risk score of 92/100 (2 detections).

Skillgate found one or more attack-shaped patterns - the kind used for credential exfiltration, remote code execution, or instruction hijack. Do not load this file into an agent without reading it end to end.

What was found

• SG-087 External binary/archive payload reference - MEDIUM: Instruction in a markdown/agent-config file routes the agent to extract or execute content from a binary/archive sibling whose contents are not visible to this scan. Indirection itself is signal; manual review of the referenced file is advised.
• SG-015 Unusual Metadata - LOW: YAML fields not in the standard schema

What to do

Read the flagged lines in the source file yourself before installing it or letting an agent load it. Every detection above links to the rule that fired, with the conditions that trigger it and remediation where one exists. Open the interactive report for evidence lines and context.

About Skillgate

Skillgate is a free scanner from Mitiga Labs for AI agent skills, hooks, MCP configs, and instruction files (SKILL.md, CLAUDE.md, AGENTS.md, .cursorrules, .claude/settings.json). It runs static rules plus an LLM judge and maps each finding to a known attack technique. Static analysis only: it never executes the file it scans. No scanner is 100% accurate - a verdict is a signal, not a guarantee. Browse all detection rules.
