attack-tree-construction

attack-tree-construction is a skill for Claude Code from 26BB/agentic-awesome-skills-mcp. It costs 31 tokens per session (527 once invoked), scanned A, a copy of attack-tree-construction, MIT.

A method for mapping how an attacker could reach a goal through multiple possible steps. An attack tree is a visual breakdown of threats, paths, and defenses.

In plain words
What is it for?
Use it to model attack scenarios, find defense gaps, set priorities, and communicate security risks.
Why use it?
It makes complex security risks easier to analyze and explain. It helps reveal missing or weak protections during authorized assessments.

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

attack-tree-construction 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

  1. Ask the user to state the exact target URL, IP, account, or resource.
  2. Ask the user to confirm written authorization and the permitted scope.
  3. Show the exact command(s) and explain their expected effect.
  4. Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

AUTHORIZED USE ONLY: Use this skill only for authorized security assessments, defensive validation, or controlled educational environments.

Attack Tree Construction

Systematic attack path visualization and analysis.

Use this skill when

  • Visualizing complex attack scenarios
  • Identifying defense gaps and priorities
  • Communicating risks to stakeholders
  • Planning defensive investments or test scopes

Do not use this skill when

  • You lack authorization or a defined scope to model the system
  • The task is a general risk review without attack-path modeling
  • The request is unrelated to security assessment or design

Instructions

  • Confirm scope, assets, and the attacker goal for the root node.
  • Decompose into sub-goals with AND/OR structure.
  • Annotate leaves with cost, skill, time, and detectability.
  • Map mitigations per branch and prioritize high-impact paths.
  • If detailed templates are required, open resources/implementation-playbook.md.

Safety

  • Share attack trees only with authorized stakeholders.
  • Avoid including sensitive exploit details unless required.

Resources

  • resources/implementation-playbook.md for detailed patterns, templates, and examples.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
