recon-nmap

A network reconnaissance and security-auditing toolkit built around Nmap, a program that scans networks and identifies reachable services.

In plain words
What is it for?
It is for port scanning, identifying services and their versions, finding network assets, and detecting vulnerabilities.
Why use it?
It helps security teams discover network assets, inspect exposed services, and check for known weaknesses during approved assessments.

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

recon-nmap 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 2d 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.

sudo nmap -sS <target-ip>

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

What ships with it

5 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.

recon-nmap is a skill published in the GitHub repository AgentSecOps/SecOpsAgentKit (201 stars, last pushed 4mo ago), with no licence file. It adds 93 tokens to every session and 5,000 once invoked, about $0.0005 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.
