writing-plans

writing-plans is a skill for Claude Code, Codex from Nikolahuang/nova-cli. It costs 35 tokens per session (598 once invoked), scanned A, original, MIT.

A format for breaking software work into small implementation tasks with exact files, code, and checks; TDD means writing tests before the code they verify.

In plain words
What is it for?
Use it to write detailed coding plans, include complete snippets, define test steps, and organise work using test-driven development.
Why use it?
It turns a broad feature request into an ordered plan that another developer can follow and validate step by step.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

writing-plans 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.

What it actually says

编写计划 - 从设计到实施

概述

将批准的设计分解为详细的实施计划。每个任务都足够小(2-5 分钟),包含确切的文件路径、完整代码和验证步骤。

计划格式

# 实施计划: [功能名称]

## 概述
[1-2 段简短描述]

## 技术上下文
- 语言: [语言和版本]
- 框架: [框架及版本]
- 关键依赖: [列出]

## 任务清单

### 任务 1: [简短描述]
**文件**: `path/to/file.ts`
**时间**: 2-5 分钟

**要编写的代码**:
```typescript
// 完整可运行的代码

验证步骤:

  1. [具体验证命令或测试]
  2. [预期输出]

任务 2: [简短描述]

...


## 编写指南

### 任务大小
- 每个任务 2-5 分钟
- 单一职责
- 明确的开始和结束

### 代码完整性
- 完整可运行的代码片段
- 包含必要的导入
- 包含类型定义

### 验证
- 具体的验证命令
- 预期的输出或行为
- 测试命令(如适用)

## TDD 集成

如果使用测试驱动开发:

```markdown
### 任务 1.1: 写失败的测试
**文件**: `path/to/file.test.ts`

```typescript
test('功能描述', () => {
  // 测试代码
});

验证: npm test → 测试应该失败

任务 1.2: 写最小实现

文件: path/to/file.ts

// 最小通过代码

验证: npm test → 测试应该通过


## 关键原则

- **粒度适中** - 小到可以快速验证
- **完整性** - 包含所有必要信息
- **可验证** - 每步都有明确的验证方式
- **顺序合理** - 依赖关系清晰
- **YAGNI** - 只计划当前需要的功能

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.

writing-plans is a skill published in the GitHub repository Nikolahuang/nova-cli (14 stars, last pushed 4mo ago), licensed MIT. It adds 35 tokens to every session and 598 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.
