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 5.1 | $0.00057 | $0.01024 |
| Opus 5 | $0.00028 | $0.00512 |
| Sonnet 5 | $0.00011 | $0.00205 |
| Haiku 4.5 | $0.00006 | $0.00102 |
Grade A, and why
shodan-recon 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 12d 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.

Shodan Recon — Passive Intelligence Gathering
Query Shodan API for passive reconnaissance data. No packets are sent to the target.
Decision Loop: Out-of-Loop (passive — no active scanning)
Safety
This skill uses only the Shodan API — no direct connection to the target is made. It is safe for passive reconnaissance without target notification.
Verify Shodan API key is configured:
shodan info 2>&1
If not configured: "Shodan API key not set. Run: shodan init <API_KEY>"
Modes
1. Host Lookup (host <ip>)
shodan host <ip> 2>&1 | tee /tmp/shodan-host.txt
2. Search (search <query>)
shodan search --fields ip_str,port,org,hostnames "<query>" --limit 20 2>&1 | tee /tmp/shodan-search.txt
3. Domain Info (domain <domain>)
shodan domain <domain> 2>&1 | tee /tmp/shodan-domain.txt
4. DNS Resolve (dns <domain>)
shodan resolve <domain> 2>&1 | tee /tmp/shodan-dns.txt
5. Honeypot Score (honeyscore <ip>)
shodan honeyscore <ip> 2>&1
Default Behavior
If no mode specified, infer from input:
- IP address →
hostmode - Domain name →
domainmode - Search query →

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.

shodan-recon is a skill published in the GitHub repository mahuttha/offensive-recon (4 stars, last pushed 6mo ago), licensed MIT. It adds 57 tokens to every session and 1,024 once invoked, about $0.0003 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 2026-08-31.
