waf-profiler

waf-profiler is an agent for Claude Code from H-mmer/pentest-agents. It costs 57 tokens per session (1,234 once invoked), scanned A, original, no licence file.

An agent that identifies web application firewalls (WAFs), which are systems that block requests matching security rules, and maps how those rules behave.

In plain words
What is it for?
Use it to fingerprint a WAF, test its blocking rules, document its behaviour, and find bypass techniques before XSS or injection testing.
Why use it?
It helps show which requests a WAF blocks and where its filtering may be bypassed, giving later security testing a clearer picture of the target's protections.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

waf-profiler 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 8d 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.

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.
