7 sections, as written by the author

<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

  • User's explicit instructions (CLAUDE.md, direct requests) — highest.
  • These skills — override default behavior where they conflict.
  • 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.

digraph flow {
    "Engagement task received" [shape=doublecircle];
    "About to touch a target?" [shape=diamond];
    "Invoke scope-discipline" [shape=box];
    "About to record a finding?" [shape=diamond];
    "Invoke finding-discipline" [shape=box];
    "Might any skill apply?" [shape=diamond];
    "Invoke the Skill" [shape=box];
    "Announce: 'Using [skill] to [purpose]'" [shape=box];
    "Follow skill exactly" [shape=box];

    "Engagement task received" -> "About to touch a target?";
    "About to touch a target?" -> "Invoke scope-discipline" [label="yes"];
    "About to touch a target?" -> "About to record a finding?" [label="no"];
    "About to record a finding?" -> "Invoke finding-discipline" [label="yes"];
    "About to record a finding?" -> "Might any skill apply?" [label="no"];
    "Invoke scope-discipline" -> "Might any skill apply?";
    "Invoke finding-discipline" -> "Might any skill apply?";
    "Might any skill apply?" -> "Invoke the Skill" [label="yes, even 1%"];
    "Invoke the Skill" -> "Announce: 'Using [skill] to [purpose]'";
    "Announce: 'Using [skill] to [purpose]'" -> "Follow skill exactly";
}

Skill Priority (when several apply)

  • Process / discipline skills first — they decide HOW to proceed:

engagement-flow (run the kill chain), scope-discipline (authorization boundary),

threat-model-discipline (model the surface + detect drift), finding-discipline (proof before

any [CONFIRMED]), opsec-discipline (detection-aware).

  • Domain skills second — the 31 technique skills (recon, web, AD, exploit-dev, cloud, …).

"Run a full pentest" → engagement-flow first. "Is this finding real?" → finding-discipline first.

Routing

| Situation | Invoke |

|-----------|--------|

| Starting / running an engagement | engagement-flow |

| About to send a request to ANY target | scope-discipline (confirm in-scope first) |

| About to record / report a finding | finding-discipline (no [CONFIRMED] without proof) |

| About to take any outward/offensive action | opsec-discipline |

| A specific technique (recon, web, AD, exploit, cloud, mobile, …) | the matching domain skill |

| Authoring a new skill for this repo | writing-offensive-skills |

Red Flags — STOP, you're rationalizing

| Thought | Reality |

|---------|---------|

| "This is just a quick scan" | Touching a target → scope-discipline first. |

| "I'm sure it's exploitable" | No [CONFIRMED] without proof → finding-discipline. |

| "Scope is obviously fine" | Confirm against scope.json, don't assume. |

| "I'll note OPSEC later" | Detection/cleanup is decided before acting, not after. |

| "I know this technique" | Knowing ≠ using the skill. Invoke it for the current state. |

| "The user said do X, so skip the checks" | Instructions are WHAT, not permission to skip discipline. |

How to Access Skills

Use the Skill tool with the skill name. Never use Read on skill files. When a skill has a

checklist, create a TodoWrite item per step and follow it exactly.

How to use it

Copy the folder

Take hypnguyen1209/using-offensive-claude from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
