hunt-graphql

hunt-graphql is a skill for Claude Code, Codex from x-cookie/cbughunter-k2. It costs 99 tokens per session (4,608 once invoked), scanned C, original, no licence file.

A security-testing guide for finding GraphQL vulnerabilities. GraphQL is an API query system that lets clients request specific data and actions.

In plain words
What is it for?
Use it when testing GraphQL APIs for unauthorized data access, server-side request forgery, denial-of-service risks, injection, and authentication or authorization flaws.
Why use it?
It gives developers documented attack patterns to check instead of having to discover common GraphQL security mistakes from scratch.

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 C, and why

hunt-graphql scanned grade C 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 9d 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.
