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 | $0.00026 | $0.00859 |
| Opus 5 | $0.00013 | $0.00430 |
| Sonnet 5 | $0.00005 | $0.00172 |
| Haiku 4.5 | $0.00003 | $0.00086 |
Grade A, and why
quality 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 3d 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
代码质量保障
关联 Agent:
code-reviewer（代码质量审查）、code-simplifier（简化重构）、security-reviewer（安全与质量交叉）
本技能提供代码质量保障策略，整合安全审查和系统化调试方法。

子技能
1. security（安全审查）
适用场景：
- 认证授权实现
- 用户输入处理
- 密钥和敏感数据
- API 端点设计
使用方式：/security 或参阅 skills/security/SKILL.md
2. debug（调试方法）
适用场景：
- 代码问题调试
- 错误日志分析
- 性能问题诊断
- 生产事故排查
使用方式：/debug 或参阅 skills/debug/SKILL.md
3. code-health（健康评估）
适用场景：
- Sprint 规划时评估技术债务
- 重构决策前分析热点文件
- 代码复杂度趋势监控
- 依赖健康状态检查
使用方式：参阅 skills/quality/code-health.md
质量检查清单
提交前必检
- 无硬编码密钥/密码
- 用户输入已验证/转义
- 错误处理完善
- 日志不泄露敏感信息
- 测试覆盖关键路径
定期审查
- 依赖安全更新
- 权限最小化原则
- 日志和监控完善
- 错误处理一致性
记住：安全和可靠性不是事后补救，而是设计阶段就要考虑的核心需求。
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.

quality is a skill published in the GitHub repository xiaobei930/cc-best (50 stars, last pushed 2mo ago), licensed MIT. It adds 26 tokens to every session and 859 once invoked, about $0.0001 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 2026-09-03.
