portscan

A command that first finds open network ports and then examines the services and versions running on them.

In plain words
What is it for?
Use it during infrastructure security testing to scan a host, identify services and possible operating systems, record versions, and flag unusual or potentially outdated services.
Why use it?
It combines quick discovery with more detailed checks, making it easier to understand which network services are exposed.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

portscan 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 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.

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.

What it actually says

Storage Policy: ALL output files MUST be saved in the project directory. NEVER write to /tmp/ or any system temporary directory.

Port Scan

Target: $ARGUMENTS

Execute a two-phase port scan using Hexstrike MCP tools.

Step 1: Load Tools

Use ToolSearch to load:

  • rustscan_fast_scan — ultra-fast port discovery
  • nmap_advanced_scan — detailed service/version/script scanning

Step 2: Fast Discovery

Run rustscan_fast_scan against the target with a high batch size for speed. This identifies all open ports quickly.

Step 3: Detailed Enumeration

Take the open ports discovered by RustScan and run nmap_advanced_scan against only those ports with:

  • Service version detection (-sV)
  • Default NSE scripts (-sC)
  • OS detection if possible (-O)
  • Appropriate timing template (T3 for remote targets behind WAF, T4 for direct targets)

Step 4: Results

Present findings as a table:

Port Service Version Notes

Save detailed results to portscan-{target}.md in the project directory.

Flag any interesting findings: unusual ports, outdated versions, services with known CVEs.

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.

portscan is a command published in the GitHub repository ogrodev/fsociety (20 stars, last pushed 5mo ago), licensed MIT. It adds 9 tokens to every session and 307 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
