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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00082 | $0.02772 |
| Opus 5 | $0.00041 | $0.01386 |
| Sonnet 5 | $0.00016 | $0.00554 |
| Haiku 4.5 | $0.00008 | $0.00277 |
Grade C, and why
SubdomainEnum scanned grade C with 2 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.

SubdomainEnum
Subdomain enumeration following Jason Haddix's Bug Hunter's Methodology (TBHM), with intelligent target prioritization.
Philosophy:
"For every subdomain you find, you 2x your chance of hacking the target. For every apex domain you find, you 4x your chance of hacking the target." — Jason Haddix
Workflow Routing
| Workflow | Trigger | What It Does |
|---|---|---|
| Light | "quick subdomains", "fast enum", "light recon", "find subdomains", DEFAULT | subfinder -all → httpx probe → prioritize |
| Full | "full enum", "comprehensive", "all subdomains", "thorough recon", "full recon" | All tools parallel → aggregate → httpx probe → prioritize |
| Probe | "probe subdomains", "check live hosts" | httpx against provided list → prioritize |
When executing, announce:
Running the **Light** workflow from **SubdomainEnum**...
Light Workflow (Default)
When to use: Quick reconnaissance, time-sensitive, initial target assessment.
Time: 1-5 minutes
Tools: subfinder, httpx, PrioritizeTargets
Steps
- Create output directory:
mkdir -p recon_{domain}_{timestamp}
cd recon_{domain}_{timestamp}
- Run subfinder with all sources:
subfinder -d {domain} -all -o subdomains-raw.txt
- Deduplicate and sort:
sort -u subdomains-raw.txt > subdomains.txt
echo "Found $(wc -l < subdomains.txt) subdomains"
- Probe with httpx (JSON for prioritization):
httpx -l subdomains.txt -silent -status-code -title -tech-detect -json -o probe.json
httpx -l subdomains.txt -silent -o live.txt
echo "$(wc -l < live.txt) live hosts"
- Generate prioritized report:
bun ~/clawd/skills/SubdomainEnum/tools/PrioritizeTargets.ts \
--input probe.json --output report.md
- Report summary to user:
Found X subdomains, Y are live.
🔴 CRITICAL: N targets
🟠 HIGH: N targets
🟡 MEDIUM: N targets
⚪ LOW: N targets
Top targets:
1. admin.target.com (Score: 95) - Admin panel
2. api-staging.target.com (Score: 82) - Dev environment + API
3. jenkins.target.com (Score: 78) - CI/CD exposed

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.

SubdomainEnum is a skill published in the GitHub repository SecurityTalent/bugskill-ai (5 stars, last pushed 17d ago), licensed MIT. It adds 82 tokens to every session and 2,772 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
