recon

recon is a command for coding agents from Zyrexnn/Cybermes. It costs 0 tokens per session (3,446 once invoked), scanned A, a copy of recon, Apache-2.0.

A command that maps a website's technical attack surface, meaning the hosts, URLs, technologies, and known weaknesses exposed by that website. It combines subdomain discovery, live-host checks, crawling, pattern matching, and vulnerability scanning.

In plain words
What is it for?
Finding subdomains and live hosts, crawling current and historical URLs, grouping URLs by likely bug type, and scanning for known vulnerabilities or configuration errors.
Why use it?
It gathers reconnaissance results into one prioritized view instead of requiring each discovery step to be run separately.

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

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.

name: recon description: Run full recon pipeline on a target — subdomain enum (Chaos API + subfinder), live host discovery (dnsx + httpx), URL crawl (katana + waybackurls + gau), gf pattern classification, nuclei scan. Outputs to recon// directory. Usage: /recon target.com

/recon

Run the full recon pipeline on a target and produce a prioritized attack surface.

What This Does

  1. Enumerates subdomains (Chaos API + subfinder + assetfinder)
  2. Resolves DNS and finds live hosts (dnsx + httpx with status/title/tech)
  3. Crawls URLs (katana deep crawl + waybackurls + gau historical)
  4. Classifies URLs by bug class (gf patterns)
  5. Runs nuclei for known CVEs and misconfigs
  6. Outputs prioritized attack surface summary

Usage

/recon target.com

Or with specific focus:

/recon target.com --focus api
/recon target.com --focus auth
/recon target.com --fast     (skip historical URLs)

Steps

Step 1: Subdomain Enumeration

TARGET="$1"
mkdir -p recon/$TARGET

# Chaos API (ProjectDiscovery — most comprehensive)
curl -s "https://dns.projectdiscovery.io/dns/$TARGET/subdomains" \
  -H "Authorization: $CHAOS_API_KEY" \
  | jq -r '.[]' > recon/$TARGET/subdomains.txt

# subfinder + assetfinder
subfinder -d $TARGET -silent | anew recon/$TARGET/subdomains.txt
assetfinder --subs-only $TARGET | anew recon/$TARGET/subdomains.txt

echo "[+] Subdomains: $(wc -l < recon/$TARGET/subdomains.txt)"

Step 2: Live Host Discovery

# DNS resolve + HTTP probe with tech detection
cat recon/$TARGET/subdomains.txt \
  | dnsx -silent \
  | httpx -silent -status-code -title -tech-detect \
  | tee recon/$TARGET/live-hosts.txt

echo "[+] Live hosts: $(wc -l < recon/$TARGET/live-hosts.txt)"

Step 3: URL Crawl

# Active crawl
cat recon/$TARGET/live-hosts.txt | awk '{print $1}' \
  | katana -d 3 -jc -kf all -silent \
  | anew recon/$TARGET/urls.txt

# Historical URLs
echo $TARGET | waybackurls | anew recon/$TARGET/urls.txt
gau $TARGET --subs | anew recon/$TARGET/urls.txt

echo "[+] Total URLs: $(wc -l < recon/$TARGET/urls.txt)"

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 is a command published in the GitHub repository Zyrexnn/Cybermes (668 stars, last pushed 4d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 3,446 tokens. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to recon, differing in 0 lines, and is treated as a copy.
