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 | $0.00047 | $0.01072 |
| Opus 5 | $0.00023 | $0.00536 |
| Sonnet 5 | $0.00009 | $0.00214 |
| Haiku 4.5 | $0.00005 | $0.00107 |
Grade B, and why
whatweb-scan scanned grade B 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 10d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

WhatWeb Scan — Technology Fingerprinting
Identify web technologies, CMS platforms, frameworks, and server software using WhatWeb.
Decision Loop: Out-of-Loop at level 1 (passive), In-the-Loop at level 3-4 (aggressive)
Safety
| Aggression Level | Behavior | Approval |
|---|---|---|
| 1 (Stealthy) | Single HTTP request | Not required |
| 2 (Unused) | Not used | — |
| 3 (Aggressive) | Multiple requests, follow links | Required |
| 4 (Heavy) | Many requests, test all plugins | Required — may trigger alerts |
For level 3-4, confirm with user before scanning.
Arguments
Parse the user's input for:
<target-url>— URL to fingerprint (REQUIRED)--aggression— Aggression level 1-4 (default: 1)
Execution
# Single target
whatweb -a <aggression> --log-json=/tmp/whatweb-output.json "<target-url>" 2>&1 | tee /tmp/whatweb-console.txt
# Multiple targets from file
whatweb -a <aggression> --log-json=/tmp/whatweb-output.json -i /tmp/targets.txt 2>&1
# With verbose output
whatweb -a <aggression> -v --log-json=/tmp/whatweb-output.json "<target-url>" 2>&1
Output Format
Parse the WhatWeb output and present:

### คำแนะนำถัดไป (Next Steps)
1. Run `/nuclei-scan <target> --mode full` to test for CMS-specific vulnerabilities
2. Run `/nikto-scan <target>` for web server misconfigurations
3. Check technology versions against CVE databases
4. Run `/nmap-scan <target>` for port-level service detection
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.

whatweb-scan is a skill published in the GitHub repository mahuttha/offensive-recon (4 stars, last pushed 6mo ago), licensed MIT. It adds 47 tokens to every session and 1,072 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
