What it does

Performing Cloud Asset Inventory With Cartography is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Run Cartography to sync AWS, GCP, or Azure resources into a Neo4j graph database, mapping relationships such as IAM permission chains, network paths, and cross-account trust. Use when building a cloud asset inventory, querying the graph to identify attack paths, or generating security reports across multi-cloud infrastructure.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts, reference files and assets (for example `assets/template.md`, `references/api-reference.md` and `references/standards.md`).

It sits in DevOps & Cloud, covering Cloud architecture. It works with Neo4j, Amazon Web Services, Google Cloud and Microsoft Azure. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.

When your agent uses it

  • Building a cloud asset inventory
  • Querying the graph to identify attack paths
  • Generating security reports across multi-cloud infrastructure

Example prompts

  • “/performing-cloud-asset-inventory-with-cartography”

Requirements

  • Python 3
  • Docker

What it can do on your machine

Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • pip
    • docker

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com
    • cartography.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • NEO4J_PASSWORD

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Performing Cloud Asset Inventory With Cartography loads about 1.7k tokens when it runs, and up to ~3.3k if it reads all its reference files. Until then it costs about 95 tokens; SKILL.md has 276 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Performing Cloud Asset Inventory with Cartography

Overview

Cartography is a CNCF sandbox project (originally created at Lyft) that consolidates infrastructure assets and their relationships into a Neo4j graph database. It queries cloud APIs to discover resources, maps relationships between them, and enables security teams to identify attack paths, generate asset reports, and find areas for security improvement. The graph model reveals hidden connections such as IAM permission chains, network paths, and cross-account trust relationships.

When to Use

  • When conducting security assessments that involve performing cloud asset inventory with cartography
  • When following incident response procedures for related security events
  • When performing scheduled security testing or auditing activities
  • When validating security controls through hands-on testing

Prerequisites

  • Python 3.8+
  • Neo4j 4.x or 5.x database
  • Cloud provider credentials (AWS, GCP, Azure)
  • Docker (optional, for Neo4j deployment)
  • Minimum 4GB RAM for Neo4j, more for large environments

Installation

bash
# Install Cartography
pip install cartography

# Verify installation
