internal-appsec-testing

internal-appsec-testing is a cursor rule for Cursor from wtalaat78/Blue-Team-Skills. It costs 414 tokens per session, scanned A, original, no licence file.

A set of rules for authorised application-security testing using methods such as OWASP Top 10 and STRIDE. OWASP Top 10 is a list of common web-application security risks, while STRIDE is a model for identifying types of threats.

In plain words
What is it for?
It helps test applications for common security weaknesses, score risks with CVSS v3.1 and an 11-domain assessment, create pre-fix reports, and define SOC detection rules.
Why use it?
It gives security checks a defined process and vocabulary instead of relying on ad-hoc testing. It also structures findings with severity scoring, reports, and detection rules.

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

internal-appsec-testing 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 6d 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
