pentest-recon

pentest-recon is a skill for Claude Code from fatihkan/badi. It costs 83 tokens per session (1,139 once invoked), scanned A, original, MIT.

A guide for reviewing reconnaissance results, meaning information gathered about systems before security testing. It parses outputs from tools such as Nmap, Nessus, Nikto, BloodHound, and subdomain searches, then suggests priorities.

In plain words
What is it for?
Use it to inspect scan reports, identify likely attack surfaces, find high-value paths in BloodHound graphs, expand domains with WHOIS or certificate data, and suggest next checks.
Why use it?
It helps turn lists of ports, services, domains, vulnerabilities, and relationships into a focused testing order instead of treating every result equally.

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

pentest-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 3d 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.

pentest-recon

Recon output analysis + attack-surface prioritization + next-step suggestions. Advisory mode — the user pastes output, the skill analyzes it. Active command composing requires a scope declaration.

Triggers

  • "nmap output" / "review the scan result"
  • "Nessus report"
  • "I ran a subdomain enum"
  • "where is the attack surface"
  • "which target is the priority"
  • "BloodHound graph analysis"
  • "let's do OSINT"

Input Types

Input Skill Behavior
Nmap XML/text output Port + service + version + script output parse, CVE lookup suggestion
Nessus / OpenVAS report Severity + CVSS prioritize, critical findings list
Nikto output Web vulnerability filtering, false positives weeded out
BloodHound JSON Find high-value target paths, attack path prioritization
Masscan/Naabu output Open-port list -> service enum suggestion
WHOIS / certificate transparency Subdomain expansion, additional domain discovery

Output Template

## Recon Analysis — <target>

### Detection
- 3 open ports: 22/SSH, 80/HTTP, 443/HTTPS
- HTTP: nginx 1.18.0 (CVE-2021-23017)
- HTTPS: Self-signed cert, expired 2024-03-15
- SSH: OpenSSH 7.6p1 (CVE-2018-15473)

### Prioritization
1. [HIGH] CVE-2021-23017 — nginx DNS resolver — exploitable, public PoC available
2. [MEDIUM] OpenSSH user enum (CVE-2018-15473) — username discovery
3. [LOW] Cert expired — config issue, no exploitation value

### Next Step (suggested)
- Active: `nikto -h <target>` (MODERATE OPSEC)
- Passive: SecurityTrails / Censys additional subdomains (QUIET)
- Targeted: nginx version-specific exploit-db search

### Skipped Areas
- UDP scan not done (53, 161 standard practice)
- Vhost discovery skipped

Active Command Composing (Scope Required)

If the user grants scope approval, the skill can suggest the following commands (with examples):

# QUIET — passive subdomain enum
subfinder -d example.com -silent

# MODERATE — TCP service scan, rate-limited
nmap -sT -sV --top-ports 1000 --max-rate 100 -oA scan_example_$(date +%Y%m%d_%H%M%S) <target>

# MODERATE — HTTP fingerprint
httpx -l hosts.txt -title -tech-detect -status-code -o httpx-results.txt

# QUIET — Cert transparency
curl for crt.sh: 'https://crt.sh/?q=%25.example.com&output=json'

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.

pentest-recon is a skill published in the GitHub repository fatihkan/badi (7 stars, last pushed 2d ago), licensed MIT. It adds 83 tokens to every session and 1,139 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
