internal-recon

internal-recon is a skill for Claude Code, Codex from wgpsec/AboutSecurity. It costs 74 tokens per session (1,064 once invoked), scanned A, original, no licence file.

A guide to discovering hosts, ports, services, and important systems inside a private network, then mapping the network topology. A topology map shows how systems and network segments are connected.

In plain words
What is it for?
It covers live-host discovery, port scanning, service identification, and locating domain controllers, databases, mail servers, and file servers.
Why use it?
It gives an authorized tester a clear view of the internal environment after gaining an initial foothold, reducing guesswork about what to examine next.

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.

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

internal-recon 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 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.

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.
