Reverse Skill is a routing package for AI coding agents that selects appropriate reverse-engineering, penetration-testing, and security-research methods and tools for a given target. It is used for tasks involving APKs, binaries, frontend JavaScript, packet captures, CTF challenges, and authorized penetration testing. Its catalogue add-ons provide the skills and instructions that guide these workflows.
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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.01794 |
| Opus 5.5 | $0.00015 | $0.00718 |
| Sonnet 5.5 | $0.00007 | $0.00359 |
| Haiku 4.5 | $0.00004 | $0.00179 |
Grade A, and why
supply-chain-security 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 1mo 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.

SBOM / SCA / CI/CD 管道 / 依赖溯源 法规驱动:美国行政令 SBOM、中国国标、EU CRA
适用场景
- 软件供应链安全评估
- 开源依赖漏洞扫描与验证
- CI/CD 管道安全审计
- 容器镜像安全分析
- 第三方组件合规审查
- 构建产物溯源与完整性验证
六层供应链治理框架
Layer 1: 源码信任评估 → 上游仓库/维护者/发布历史审查
Layer 2: 构建管道集成 → CI/CD 安全门禁、签名验证
Layer 3: 制品分发完整性 → 签名、校验和、SBOM 附加
Layer 4: 运行时保护 → 容器扫描、准入控制
Layer 5: 持续监控 → CVE 实时追踪、漏洞可达性分析
Layer 6: 事件响应 → 供应链攻击应急、回滚策略
工作流
1. SBOM 生成与审计
生成 SBOM:
□ CycloneDX 格式: cdxgen → bom.json
□ SPDX 格式: sbom-tool generate
□ Syft: syft <image|dir> -o spdx-json
审计要点:
□ 是否存在未知/未授权的依赖
□ 是否存在已废弃/停止维护的包
□ 许可证冲突检测
□ 直接依赖 vs 传递依赖清单
□ 每个组件的发布时间线和维护者状态
2. 软件组成分析(SCA)
# OSV-Scanner(免费、Google 维护)
osv-scanner scan -r . --format json
# OWASP Dependency-Track(企业级持续监控)
docker run -p 8080:8080 dependencytrack/apiserver
# → 上传 SBOM → 自动匹配 NVD/OSV/GitHub Advisory
# Snyk(商业)
snyk test --all-projects
snyk monitor # 持续监控
# Trivy(容器 + 依赖 + IaC)
trivy fs . # 文件系统扫描
trivy image nginx # 容器镜像
trivy config . # IaC 配置
3. 漏洞可达性验证
SCA 告警 ≠ 实际风险!大多数 SCA 工具只有 ~15% 的告警是实际可达的。
验证步骤:
1. 用 Dependency-Track 或 Trivy 获取 CVE 列表
2. 筛选 CVSS ≥ 7.0 的漏洞
3. 对有 PoC 的 CVE 做可达性分析
- Code Property Graph 切片: 追踪用户输入到漏洞函数的路径
- DEPTEX 方法: EPD (Execution Path Dominance) + LLM 语义验证
4. 在隔离环境中验证 PoC
5. 对可达的漏洞按实际影响排序修复优先级
工具参考:
- CodeQL: GitHub 代码查询 → 数据流分析
- Snyk Code: 可达性标记
- DEPTEX: LLM 辅助上下文感知风险评估
4. CI/CD 管道安全
安全检查点:
□ 代码提交 → pre-commit hook: gitleaks (密钥扫描)
□ PR 阶段 → SCA 扫描 (Trivy/OSV-Scanner)
□ 构建阶段 → 制品签名 (cosign)
□ 推送阶段 → SBOM 附加 (syft + attest)
□ 部署阶段 → 准入控制 (OPA/Kyverno + 镜像扫描)
□ 运行时 → 持续漏洞监控 (Dependency-Track)
管道自身安全:
□ Pipeline as Code 审计(GitHub Actions / GitLab CI 配置注入)
□ Runner 隔离(防止恶意构建突破容器)
□ 密钥管理(Actions Secrets / Vault,禁止硬编码)
□ 第三方 Action 审查(锁定 commit SHA,非 tag)
What ships with it
2 files 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.
- 1mo ago First seen · 173 lines · 37 tokens per session scan A 21071161959f
supply-chain-security is a skill published in the GitHub repository zhaoxuya520/reverse-skill (43,575 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 1,794 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
