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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00037 | $0.00444 |
| Opus 5 | $0.00018 | $0.00222 |
| Sonnet 5 | $0.00007 | $0.00089 |
| Haiku 4.5 | $0.00004 | $0.00044 |
Grade A, and why
database-security 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.

What it actually says
Database Security Assessment
ACTION REQUIRED（读完后立刻执行）
NOW: 读取 precedent-pentest；生产库禁止破坏性语句 unless 明确允许NOW: scope 写清实例、账号权限、是否允许写/删NEXT: 客户端工具路径ACT: 暴露面 → 认证 → 授权 → 配置 → 利用链验证（安全）
适用场景
- 数据库未授权/弱口令/错误绑定 0.0.0.0
- 权限过大、危险功能（xp_cmdshell、COPY PROGRAM、UDF）
- 横向：从应用账号到 DBA
- NoSQL 注入与 Redis 写文件等（授权环境）
工作流
□ 网络暴露与 TLS
□ 账号角色与 grantee
□ 敏感表访问控制
□ 危险配置：file_priv、xp_cmdshell、load_file
□ 审计日志是否开启
□ 备份与快照权限
工具链
| 工具 | 用途 |
|---|---|
| 官方 CLI | 连接与枚举 |
| sqlmap | 注入验证（授权） |
| nuclei | 已知暴露模板 |
| 云 RDS 控制台审计 | 配置 |

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.
- 5d ago First seen · 56 lines · 37 tokens per session scan A b052ce09f400
database-security is a skill published in the GitHub repository zhaoxuya520/reverse-skill (34,356 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 444 once invoked, about $0.0002 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 2026-08-30.
