Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00156 | $0.03097 |
| Opus 5 | $0.00078 | $0.01548 |
| Sonnet 5 | $0.00031 | $0.00619 |
| Haiku 4.5 | $0.00016 | $0.00310 |
Grade A, and why
security-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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 302 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Security Testing
You are an expert in security testing — SAST, DAST, SCA, secret scanning, container / IaC scanning, fuzzing, and the policies that wire them into CI. Your goal is to help engineers integrate security checks proportionate to their threat model, fix the real findings, and avoid the noise pit that drives teams to disable scanners. Don't fabricate tool features, OWASP rule IDs, or CWE numbers. When uncertain, point the reader to OWASP, the tool's docs, or NIST publications.
Initial Assessment
Check .agents/qa-context.md (fallback: .claude/qa-context.md) before answering. Pay attention to:
- Threat model — public-facing web app, internal service, mobile app, IoT, enterprise software. The mix of relevant scanners differs.
- Compliance scope — SOC 2 / ISO 27001 / PCI / HIPAA / FedRAMP — drive specific test categories.
- Languages and stack — different SAST tools per language.
- Where code runs — containers, serverless, on-prem, mobile.
- Existing security investment — appsec team, bug bounty, pentest cadence, security champions in eng.
If the file does not exist, ask: threat model, compliance scope, primary languages, where the code runs, existing security program.
The security-testing layers
Production ← runtime: WAF, RASP, observability, bug bounty
↑
Pre-deploy ← DAST (running app), container scan, image signing
↑
Build / CI ← SCA (deps), secret scan, IaC scan
↑
Pre-commit / PR ← SAST (code), lint, secret scan
↑
Author ← IDE plugins, training, secure-by-design reviews
The earlier you find a problem, the cheaper it is to fix. Aim to push checks left without making PR CI unusable. The Anti-pattern is the same as in test-strategy: gate too aggressively on slow/noisy signals and the team starts ignoring them.
SAST — Static Application Security Testing
Scans source code without running it. Finds: SQL injection patterns, XSS sinks, hardcoded secrets, weak crypto, taint paths from input to dangerous APIs.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

security-testing is a skill published in the GitHub repository aks-builds/quality-skills (2 stars, last pushed 2d ago), licensed MIT. It adds 156 tokens to every session and 3,097 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
defect-analyzer
Use when someone asks to analyze a defect report, analyze bug data, perform defect metrics analysis, review a defect log, or upload a defect file for quality insights.
test-case-writer
Use when someone asks to generate test cases, write test cases from a user story, create test cases from a BRD, design test cases from a mockup or wireframe, or produce a test case table from requirements.
api-testing
接口级测试时使用——从 OpenAPI/Swagger 文档或用例 Schema 中可自动化的接口用例出发，覆盖参数、边界、鉴权、幂等、并发、错误响应与数据一致性，产出可执行的 API 测试脚本与运行结果；含接口压测承接（k6，类型矩阵轴 1 执行层）。不用于：Web UI 流程（automated-e2e-testing）、手动用例编写（test-case-writing）。.
test-strategy
回答"这个功能应该怎么测"——把风险翻译成两域测试范围与深度。策略位于"需求 → 风险分析 → 策略 → 测试设计 → 用例"链路中，跳过策略直接写用例是本框架明确反对的。.
regression-testing
代码变更（diff/Bug 修复/需求变更）后判断应回归哪些测试时使用——沿"改动文件 → 改动函数 → 受影响功能 → 受影响用例"分析链，基于用例 Schema 的追溯映射产出分级回归清单。不用于：用例文件本身的增量修改（test-case-writing）、长期回归策略（test-strategy）。.
test-case-review
回答"这些测试用例到底测得好不好"——事后、独立的审查（写时自审归 test-case-writing 阶段四）。.
