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 | $0.00063 | $0.00645 |
| Opus 5.5 | $0.00025 | $0.00258 |
| Sonnet 5.5 | $0.00013 | $0.00129 |
| Haiku 4.5 | $0.00006 | $0.00064 |
Grade A, and why
database-install-skill 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 21d 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 Install Skill（数据库安装父技能）
Overview
本技能是数据库软件安装的入口技能，负责接收用户请求并分发到对应的子技能。子技能位于本目录的 children/ 目录下。
子技能清单
| 子技能 | 触发词 | 职责 |
|---|---|---|
postgres-install-skill |
"安装 PostgreSQL" / "装 PG" | PostgreSQL 安装 |
mysql-install-skill |
"安装 MySQL" / "装 MySQL" | MySQL 安装 |
mongodb-install-skill |
"安装 MongoDB" / "装 Mongo" | MongoDB 安装 |
redis-install-skill |
"安装 Redis" / "装 Redis" | Redis 安装 |
When to Use
触发词：
- 安装 PostgreSQL
- 安装 MySQL
- 安装 MongoDB
- 安装 Redis
- 安装数据库
- database install
路由规则
用户说「安装 PostgreSQL」或「装 PG」
→ 分发到 postgres-install-skill
用户说「安装 MySQL」或「装 MySQL」
→ 分发到 mysql-install-skill
用户说「安装 MongoDB」或「装 Mongo」
→ 分发到 mongodb-install-skill
用户说「安装 Redis」或「装 Redis」
→ 分发到 redis-install-skill
通用交互流程
所有子技能遵循统一的交互流程：
1. 自动检测当前系统（OS + 版本 + 架构）
2. 询问安装方式（包管理器 / Docker）
3. 询问版本选择
4. [强制] 获取数据库 root 密码（不输入则拒绝继续）
5. 生成安装命令
6. 执行安装（幂等）
7. 不执行初始化，输出初始化清单供用户手动确认
8. 输出修改密码/重置密码脚本
密码安全规则
- 强制获取密码：无密码直接拒绝安装
- 密码不显示：交互式输入时不显示密码
- 密码不记录：不将密码写入脚本或日志
- 输出修改密码脚本：安装后必须输出修改密码和重置密码的参考脚本

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.
- 21d ago First seen · 75 lines · 63 tokens per session scan A 107dea79df48
database-install-skill is a skill published in the GitHub repository jiushiwon/wg-skills (120 stars, last pushed 7d ago), licensed Apache-2.0. It adds 63 tokens to every session and 645 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-30.
