poc-builder is a skill for Cursor from H-mmer/pentest-agents. It costs 51 tokens per session (1,334 once invoked), scanned A, original, no licence file.

A bug-bounty report and proof-of-concept builder for confirmed security vulnerabilities. A proof of concept is a small demonstration that shows how a problem can be reproduced.

In plain words
What is it for?
Creating minimal HTML demonstrations, curl reproduction scripts, and reports for HackerOne, Bugcrowd, and Intigriti.
Why use it?
It turns technical findings into clear reproduction steps and report drafts suitable for security-reporting platforms.

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

poc-builder scanned grade A 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
