Linux Privilege Escalation

Linux Privilege Escalation is a skill for Claude Code, Codex from tourze/ai-infra. It costs 95 tokens per session (3,257 once invoked), scanned C, original, no licence file.

A guide to finding ways to gain administrator-level access on Linux systems from a lower-privilege account.

In plain words
What is it for?
Use it to inspect sudo rules, SUID programs, scheduled tasks, and other Linux privilege-escalation paths.
Why use it?
It helps security testing uncover unsafe settings that could let an ordinary user become root, the Linux administrator account.

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 C, and why

Linux Privilege Escalation scanned grade C with 5 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 9d 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.

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

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

Reaches for credential filesmediumPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
