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 | $0.00020 | $0.02663 |
| Opus 5 | $0.00010 | $0.01332 |
| Sonnet 5 | $0.00004 | $0.00533 |
| Haiku 4.5 | $0.00002 | $0.00266 |
Grade A, and why
test-driven-development 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 4d 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 — 326 lines — stays where its author put it; the contents beside it link to each section on GitHub.
测试驱动开发(TDD)
概述
先写测试。看它失败。写最少的代码让它通过。
核心原则: 如果你没有看到测试失败,你就不知道它是否测试了正确的东西。
违反规则的字面意思就是违反规则的精神。
何时使用
始终使用:
- 新功能
- Bug 修复
- 重构
- 行为变更
例外(需询问你的人类伙伴):
- 一次性原型
- 生成的代码
- 配置文件
想着"就这一次跳过 TDD"?停下来。那是在给自己找借口。
铁律
没有失败的测试,就不写生产代码
先写了代码再写测试?删掉它。从头来过。
没有例外:
- 不要保留作为"参考"
- 不要在写测试时"改编"它
- 不要看它
- 删除就是删除
从测试出发,重新实现。句号。

verify_green -> green [label="否"];
refactor -> verify_green [label="保持\n绿灯"];
verify_green -> next;
next -> red;
}
红灯 - 编写失败的测试
写一个最小的测试来展示期望行为。
const result = await retryOperation(operation);
expect(result).toBe('success'); expect(attempts).toBe(3); });
名称清晰,测试真实行为,只测一件事
</Good>
<Bad>
```typescript
test('retry works', async () => {
const mock = jest.fn()
.mockRejectedValueOnce(new Error())
.mockRejectedValueOnce(new Error())
.mockResolvedValueOnce('success');
await retryOperation(mock);
expect(mock).toHaveBeenCalledTimes(3);
});
名称模糊,测试的是 mock 而非代码
要求:
- 一个行为
- 清晰的名称
- 使用真实代码(除非不得已才用 mock)
验证红灯 - 看它失败
必须执行。绝不跳过。
npm test path/to/test.test.ts
确认:
- 测试失败(不是报错)
- 失败信息符合预期
- 失败原因是功能缺失(不是拼写错误)
测试通过了? 你在测试已有的行为。修改测试。
测试报错了? 修复错误,重新运行直到它正确地失败。
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.

test-driven-development is a skill published in the GitHub repository jnMetaCode/superpowers-zh (7,965 stars, last pushed yesterday), licensed MIT. It adds 20 tokens to every session and 2,663 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 2026-08-30.
