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 | $0.00107 | $0.02037 |
| Opus 5.5 | $0.00043 | $0.00815 |
| Sonnet 5.5 | $0.00021 | $0.00407 |
| Haiku 4.5 | $0.00011 | $0.00204 |
Grade B, and why
webapp-exploit-hunter scanned grade B 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 1mo 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.
Cloud metadata endpointmediumServer-side request forgery
One request to 169.254.169.254 can return temporary IAM credentials.
- Cloud metadata: 169.254.169.254 (AWS), metadata.google.internal (GCP) Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Webapp Exploit Hunter
Intelligent web application vulnerability scanner. Context-aware testing that adapts to the target's technology stack.
Important
CRITICAL: Only test web applications you have explicit authorization to test (pentest agreement, bug bounty program, or own infrastructure).
Instructions
Step 1: Target Setup
Accept input as:
- Single domain or URL
- List of domains/URLs (from recon-dominator output or manual list)
- Specific endpoint to test
For each target, determine:
- Is it in scope?
- What technology stack is it running? (use tech_fingerprint.py from recon-dominator or fingerprint inline)
- Are there any testing restrictions (rate limits, no automated scanning, etc.)?
Step 2: Crawling and Endpoint Discovery
python scripts/crawler.py --target {url} --depth 3
Intelligent crawling:
- Spider all linked pages up to configured depth
- Extract forms and input parameters
- Identify API endpoints from JavaScript files
- Parse robots.txt and sitemap.xml for hidden paths
- Fuzz for common hidden endpoints
Output: Structured map of all endpoints with parameters.
Step 3: Parameter Classification
For each discovered parameter, classify:
- Input type: string, numeric, email, URL, file path, JSON, XML
- Reflection: Is input reflected in response? Where? (HTML body, attribute, JS, header)
- Sink type: Database query, file system, HTTP request, template, command, redirect
- Authentication: Does the endpoint require auth?
This classification determines which vulnerability tests are relevant.
Step 4: Vulnerability Testing
Run tests based on parameter classification. Order by severity:
4a. SQL Injection
python scripts/sqli_tester.py --target {url} --params {param_file}
Test types:
- Error-based: Single quote, double quote, comment injection
- Boolean-based blind: True/false condition comparison
- Time-based blind: SLEEP/WAITFOR/pg_sleep injection
- UNION-based: Column count detection + data extraction
- Second-order: Stored input used later in queries

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.

webapp-exploit-hunter is a skill published in the GitHub repository Orizon-eu/claude-code-pentest (28 stars, last pushed 7mo ago), licensed MIT. It adds 107 tokens to every session and 2,037 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 2 findings (cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
