Use when starting any offensive-security engagement or task — establishes how to find and invoke the right skill before any action (including clarifying questions, recon, exploitation, or reporting).
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
<SUBAGENT-STOP>
If you were dispatched as a subagent to execute a specific task, skip this skill.
</SUBAGENT-STOP>
<EXTREMELY-IMPORTANT>
If there is even a 1% chance a skill applies to what you are doing, you ABSOLUTELY MUST invoke it.
IF A SKILL APPLIES TO YOUR TASK, YOU DO NOT HAVE A CHOICE. YOU MUST USE IT.
This is not negotiable. You cannot rationalize your way out of it.
</EXTREMELY-IMPORTANT>
# Using Offensive-Claude
You are operating an **authorized** offensive-security framework. Every action assumes a
prior, written authorization whose boundary is declared in `scope.json` (see scope-discipline).
## Instruction Priority
1. **User's explicit instructions** (CLAUDE.md, direct requests) — highest.
2. **These skills** — override default behavior where they conflict.
3. **Default behavior** — lowest.
User instructions say WHAT, not HOW. "Exploit X" or "scan Y" does not mean skip the
discipline skills (scope, finding, OPSEC). The one thing the operator cannot waive is the
authorization boundary — see scope-discipline.
## The Rule
**Invoke relevant skills BEFORE any response or action.** Even a 1% chance means invoke to check.

How to install
mdr add hypnguyen1209/offensive-claude/using-offensive-claude@sha256:dc21900abf8353dbThe line at the top of this page pins the label git:20260916.d4cb295, 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.
