aws-security-analysis

aws-security-analysis is a skill for Claude Code, Codex from cyntrisec/cyntrisec-cli. It costs 47 tokens per session (1,606 once invoked), scanned A, original, Apache-2.0.

A guide for assessing the security of AWS cloud infrastructure using Cyntrisec scan data. AWS is Amazon's cloud platform, and a scan is a collected snapshot of its resources and security findings.

In plain words
What is it for?
Reviewing AWS assets and findings, checking permissions and access, explaining attack paths, comparing scans, assessing compliance, and finding remediation or Terraform suggestions.
Why use it?
It helps choose the appropriate security analysis for questions about access, vulnerabilities, attack paths, compliance, and changes over time.

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

aws-security-analysis 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 3d 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.

AWS Security Analysis

This skill guides you through analyzing AWS infrastructure security using Cyntrisec MCP tools.

Prerequisites

Before using any tool, ensure a scan exists:

  • Call get_scan_summary first to verify scan data is available
  • If you receive SNAPSHOT_NOT_FOUND, inform the user to run cyntrisec scan first

Tool Selection Guide

When User Asks About...

User Question Tool to Use
"What's in my AWS account?" get_scan_summaryget_assets
"What are the security issues?" get_findings (filter by severity if specified)
"Show me attack paths" get_attack_paths
"Explain this attack path" explain_path (requires path_id)
"How do I fix this?" get_remediationsget_terraform_snippet
"Can role X access resource Y?" check_access
"What permissions are unused?" get_unused_permissions
"Are we compliant?" check_compliance
"What changed since last scan?" compare_scans

Tool Categories

Discovery (start here)

  • get_scan_summary - Always call first to understand scope
  • list_tools - Show available capabilities

Data Retrieval

  • get_assets - Browse AWS resources (EC2, IAM, S3, RDS, Lambda)
  • get_relationships - See how assets connect (CAN_ASSUME, CAN_REACH, MAY_ACCESS)
  • get_findings - Security issues found in the scan

Attack Analysis

  • get_attack_paths - Paths from internet to sensitive targets
  • explain_path - Step-by-step breakdown of an attack path
  • explain_finding - Deep dive into a specific finding

Remediation

  • get_remediations - Optimal fixes using min-cut algorithm
  • get_terraform_snippet - IaC code to implement a fix

Advanced

  • check_access - Simulate IAM access decisions
  • get_unused_permissions - Find permission bloat
  • check_compliance - CIS AWS or SOC 2 frameworks

Common Workflows

Workflow 1: Security Assessment

User wants to understand their security posture.

1. get_scan_summary
   → Understand scope: account, regions, asset counts

2. get_findings(severity="CRITICAL")
   → Focus on highest priority issues first

3. get_attack_paths(min_risk=0.7)
   → Find high-risk paths to sensitive targets

4. explain_path(path_id=<from step 3>)
   → Understand the most critical path in detail

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.
