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 | $0.00557 | $0.04104 |
| Opus 5 | $0.00279 | $0.02052 |
| Sonnet 5 | $0.00111 | $0.00821 |
| Haiku 4.5 | $0.00056 | $0.00410 |
Grade A, and why
web-assessment 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 314 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web Vulnerability Assessment
Systematic identification and exploitation of web application vulnerabilities. This skill provides structured workflows for every major web vulnerability class, routing you to the correct Hexstrike MCP tools and Kali tooling with proper parameters. Stop guessing at payloads and tool flags -- use the right tool for the right vuln class.
Why Structured Web Assessment Matters
Web applications are the primary attack surface in most engagements. A single SQLi grants database access. An SSRF leaks cloud credentials. An SSTI yields RCE. Structured testing ensures you cover every class systematically instead of ad-hoc fuzzing. Every finding feeds the findings-tracker and chain-detector for automatic exploit chain discovery.
Triage and Prioritization
Before testing anything, determine what you are dealing with. Target type dictates testing priority.
Priority Matrix by Target Type
| Target Type | Test First | Test Second | Test Third |
|---|---|---|---|
| PHP app | SQLi, LFI/RFI, SSTI (Twig), RCE, file upload | XSS, IDOR, auth bypass | SSRF, XXE |
| Java/Spring | SQLi, SSTI (Freemarker/Velocity), XXE, deserialization | SSRF, IDOR, auth bypass | XSS, NoSQLi |
| Node.js/Express | NoSQLi, SSTI (Pug/EJS), prototype pollution, RCE | SSRF, IDOR, auth bypass | XSS, SQLi |
| Python/Django/Flask | SSTI (Jinja2), SQLi, RCE, SSRF | IDOR, auth bypass | XSS, XXE |
| Ruby on Rails | SQLi, SSTI (ERB), deserialization, mass assignment | SSRF, IDOR, auth bypass | XSS, XXE |
| API-only (REST) | IDOR/BOLA, auth bypass, SQLi/NoSQLi, mass assignment | SSRF, rate limit bypass | injection via headers |
| API-only (GraphQL) | Introspection, query depth abuse, batching attacks | IDOR, auth bypass, injection | DoS via nested queries |
| WordPress | See waf-bypass + wordpress-hacking skills | SQLi via plugins, file upload | XSS, SSRF |
| Cloud-hosted | SSRF (IMDS), config leaks, auth bypass | SQLi/NoSQLi, IDOR | RCE, XSS |
What ships with it
9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

web-assessment is a skill published in the GitHub repository ogrodev/fsociety (20 stars, last pushed 5mo ago), licensed MIT. It adds 557 tokens to every session and 4,104 once invoked, about $0.0028 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 2026-08-30.
