performing-graphql-security-assessment

performing-graphql-security-assessment is a skill for Claude Code, Codex from Njones17/AI-agent-master-cyber-skills-list. It costs 35 tokens per session (3,608 once invoked), scanned B, original, no licence file.

A security assessment for GraphQL APIs, which let clients request specific data through a shared query interface. It checks for exposed schema details, injection attacks, authorization mistakes, and requests that consume too many resources.

In plain words
What is it for?
Use it during authorized tests of GraphQL endpoints to review schema exposure, input handling, access controls, and resistance to denial-of-service attacks.
Why use it?
It helps find weaknesses that may let users see or change data they should not access or overload the API with costly queries.

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 B, and why

performing-graphql-security-assessment 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 12d 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.

-d '{"query":"mutation { importData(url: \"http://169.254.169.254/latest/meta-data/\") { result } }"}' \

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
