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 | $0.00037 | $0.02309 |
| Opus 5 | $0.00018 | $0.01154 |
| Sonnet 5 | $0.00007 | $0.00462 |
| Haiku 4.5 | $0.00004 | $0.00231 |
Grade A, and why
tdd 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 yesterday.
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.
This is a copy
91% identical to tdd — 194 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 331 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TDD 命令
此命令调用 tdd-guide 代理来强制执行测试驱动开发方法。
此命令的作用
- 搭建接口 - 首先定义类型/接口
- 首先生成测试 - 编写失败的测试(红)
- 实现最小化代码 - 编写刚好足够的代码以通过测试(绿)
- 重构 - 改进代码,同时保持测试通过(重构)
- 验证覆盖率 - 确保 80%+ 的测试覆盖率
何时使用
在以下情况下使用 /tdd:
- 实现新功能时
- 添加新函数/组件时
- 修复错误时(首先编写重现错误的测试)
- 重构现有代码时
- 构建关键业务逻辑时
工作原理
tdd-guide 代理将:
- 为输入/输出定义接口
- 编写将会失败的测试(因为代码尚不存在)
- 运行测试并验证它们因正确的原因而失败
- 编写最小化实现以使测试通过
- 运行测试并验证它们通过
- 重构代码,同时保持测试通过
- 检查覆盖率,如果低于 80% 则添加更多测试
TDD 循环
RED → GREEN → REFACTOR → REPEAT
RED: Write a failing test
GREEN: Write minimal code to pass
REFACTOR: Improve code, keep tests passing
REPEAT: Next feature/scenario
使用示例
User: /tdd I need a function to calculate market liquidity score
Agent (tdd-guide):
# TDD Session: Market Liquidity Score Calculator
## Step 1: Define Interface (SCAFFOLD)
```typescript
// lib/liquidity.ts
export interface MarketData {
totalVolume: number
bidAskSpread: number
activeTraders: number
lastTradeTime: Date
}
export function calculateLiquidityScore(market: MarketData): number {
// TODO: Implementation
throw new Error('Not implemented')
}
步骤 2:编写失败的测试(红)
// lib/liquidity.test.ts
import { calculateLiquidityScore } from './liquidity'
describe('calculateLiquidityScore', () => {
it('should return high score for liquid market', () => {
const market = {
totalVolume: 100000,
bidAskSpread: 0.01,
activeTraders: 500,
lastTradeTime: new Date()
}
const score = calculateLiquidityScore(market)
expect(score).toBeGreaterThan(80)
expect(score).toBeLessThanOrEqual(100)
})
it('should return low score for illiquid market', () => {
const market = {
totalVolume: 100,
bidAskSpread: 0.5,
activeTraders: 2,
lastTradeTime: new Date(Date.now() - 86400000) // 1 day ago
}
const score = calculateLiquidityScore(market)
expect(score).toBeLessThan(30)
expect(score).toBeGreaterThanOrEqual(0)
})
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.

tdd is a command published in the GitHub repository Luohaothu/everything-codex (24 stars, last pushed 21d ago), licensed MIT. It adds 37 tokens to every session and 2,309 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to tdd, differing in 194 lines, and is treated as a copy.
Other commands, from other repositories
checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
