engagement-flow

engagement-flow is a skill for Claude Code from hypnguyen1209/offensive-claude. It costs 38 tokens per session (783 once invoked), scanned A, original, MIT.

A workflow for planning and running a multi-stage penetration test or red-team engagement. A red-team engagement is an authorised security exercise that simulates an attacker, and the workflow follows the nine stages of the Cyber Kill Chain.

In plain words
What is it for?
Use it to sequence scoping, reconnaissance, delivery, exploitation, persistence, command and control, actions, and reporting with checks between stages.
Why use it?
It prevents teams from jumping into exploitation before scope, evidence, and earlier investigation work are complete.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

engagement-flow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Engagement Flow

Overview

A pentest/red-team engagement is a phased pipeline with gates, not a pile of techniques run ad hoc. This skill sequences the 9-phase Lockheed Martin Cyber Kill Chain and routes each phase to its commands, domain skills, and discipline checks. It is the offensive analog of brainstorming → writing-plans → executing-plans: scope the work, plan it, then execute phase by phase.

Don't jump to exploitation. Earlier phases earn the access that later phases need, and each gate keeps quality high before you advance.

The pipeline

digraph killchain {
    rankdir=LR;
    scope -> recon -> weaponize -> deliver -> exploit -> install -> c2 -> actions -> report;
    scope [label="0 SCOPE"]; recon [label="1 RECON"]; weaponize [label="2 WEAPONIZE"];
    deliver [label="3 DELIVER"]; exploit [label="4 EXPLOIT"]; install [label="5 INSTALL"];
    c2 [label="6 C2"]; actions [label="7 ACTIONS"]; report [label="8 REPORT"];
}

Each transition requires a gate (/engage.gate): required artifacts present, findings carry CWE+CVSS+ATT&CK+evidence, and the automated checks pass. Gate FAIL → fix the gap before advancing.

How to run it

  1. Pick the workflow preset for the engagement type (web-app, network, red-team, cloud, mobile, ad-domain, bug-bounty) and drive phases with the /engage.* commands.
  2. Phase 0 (scope): emit .engage/scope/scope.json. REQUIRED: scope-discipline.
  3. Phases 1-7: before any target interaction → scope-discipline; before any outward action → opsec-discipline; invoke the matching domain skill for the technique.
  4. Recall prior intel: at recon/weaponize, /engage.memory recall to start from what worked.
  5. Findings: REQUIRED: finding-discipline — nothing is [CONFIRMED] without proof.
  6. Phase 8 (report): record confirmed findings to engagement-memory; generate the report.
  7. Optional autopilot: engine/engine.py runs the phases under a budget/loop/trace with --resume (/engage.pickup); offensive actions stay operator-gated.
