system

system is a skill for Claude Code, Codex from transilienceai/communitytools. It costs 21 tokens per session (295 once invoked), scanned A, original, MIT.

A security-testing guide for operating systems and Windows Active Directory, the system many organizations use to manage users and computers. It covers privilege escalation, attacks on directory accounts, and exploit development.

In plain words
What is it for?
Use it to assess Active Directory configurations, Linux and Windows privilege boundaries, service and permission mistakes, and software vulnerabilities.
Why use it?
It helps security testers find and demonstrate ways an attacker could gain higher permissions or control of a system or domain. It also provides a structure for documenting the attack path and evidence.

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

system scanned grade A with 1 finding 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 4d 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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

| **Privilege Escalation** | SUID/sudo abuse, kernel exploits, service misconfig, token manipulation |

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

What it actually says

System

Test system-level security including Active Directory, privilege escalation, and exploit development.

Techniques

Type Key Vectors
Active Directory Kerberoasting, AS-REP roasting, DCSync, PtH, Golden/RODC Ticket, RBCD, ACL abuse, KeyList, Shadow Credentials, ADCS (ESC1-9/16)
Privilege Escalation SUID/sudo abuse, kernel exploits, service misconfig, token manipulation
Exploit Development Buffer overflow, format string, ROP chains, shellcode, heap exploitation

Workflow

  1. Enumerate system and domain information
  2. Identify escalation paths and misconfigurations
  3. Exploit with appropriate techniques
  4. Demonstrate impact (domain admin, root access)
  5. Document attack chain with evidence

Reference

  • reference/INDEX.md - Router for AD attacks, privilege escalation, and exploit-dev scenarios (see reference/scenarios/)
  • reference/format-string-exploitation.md - Format string read/write primitives, architecture differences, mitigation bypass
  • reference/heap-exploitation.md - Modern glibc heap techniques (tcache poison, unsorted bin leak, environ stack leak, ROP)
Files

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

system is a skill published in the GitHub repository transilienceai/communitytools (505 stars, last pushed 1mo ago), licensed MIT. It adds 21 tokens to every session and 295 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
