# CLAUDE.md
Behavioral guidelines to reduce common LLM coding mistakes. Merge with project-specific instructions as needed.
**Tradeoff:** These guidelines bias toward caution over speed. For trivial tasks, use judgment.
**Important:** Use Chinese for information responses and thinking; use English for searching and querying.
## 1. Think Before Coding
**Don't assume. Don't hide confusion. Surface tradeoffs.**
Before implementing:
- State your assumptions explicitly. If uncertain, ask.
- If multiple interpretations exist, present them - don't pick silently.
- If a simpler approach exists, say so. Push back when warranted.
- If something is unclear, stop. Name what's confusing. Ask.
## 2. Simplicity First
**Minimum code that solves the problem. Nothing speculative.**
- No features beyond what was asked.
- No abstractions for single-use code.
- No "flexibility" or "configurability" that wasn't requested.
- No error handling for impossible scenarios.
- If you write 200 lines and it could be 50, rewrite it.
Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.
## 3. Surgical Changes
**Touch only what you must. Clean up only your own mess.**
When editing existing code:
- Don't "improve" adjacent code, comments, or formatting.
- Don't refactor things that aren't broken.
- Match existing style, even if you'd do it differently.
- If you notice unrelated dead code, mention it - don't delete it.
When your changes create orphans:
- Remove imports/variables/functions that YOUR changes made unused.
- Don't remove pre-existing dead code unless asked.
The test: Every changed line should trace directly to the user's request.
## 4. Goal-Driven Execution
**Define success criteria. Loop until verified.**
Transform tasks into verifiable goals:
- "Add validation" → "Write tests for invalid inputs, then make them pass"
- "Fix the bug" → "Write a test that reproduces it, then make it pass"
- "Refactor X" → "Ensure tests pass before and after"
For multi-step tasks, state a brief plan:
```
1. [Step] → verify: [check]
2. [Step] → verify: [check]
3. [Step] → verify: [check]
```
Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.
---
**These guidelines are working if:** fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.

- 支持自定义输出宽度和目录
- 内置图片优化功能，使用图片优化引擎进行无损压缩
## 安装
## 新手使用说明
使用uv进行基本安装和工具设置。必要工具，推荐使用scoop进行安装。
如果你是第一次使用命令行工具，请按以下步骤操作。
### 准备工作
- **PowerPoint**：需要安装 Microsoft PowerPoint（Office 2016 或更新版本）
- **网络连接**：安装过程中需要下载工具
### 第一步：安装 uv
`uv` 是一个 Python 包管理器，用来安装 pptopic 及其依赖。
打开 PowerShell（在开始菜单搜索 "PowerShell"），进入本项目的目录：
```powershell
cd pptopic
```
运行项目自带的安装脚本：
```powershell
.\uv-installer.ps1
```
该脚本会自动下载最新版本的 uv 并添加到系统 PATH。如果你在中国大陆，脚本已内置 GitHub 加速镜像，无需额外配置。
安装完成后，**关闭并重新打开 PowerShell**，验证安装：
```powershell
uv --version
```
> 如果你已安装 [scoop](https://scoop.sh/)，也可以直接 `scoop install uv`。
> 如果想安装特定版本的 uv，可以在运行脚本前设置环境变量：`$env:UV_INSTALLER_VERSION = "0.11.20"`
### 第二步：安装 Python
使用 uv 安装 Python 3.13 或更新版本：
```powershell
uv python install 3.13
```
### 第三步：安装 pptopic
```powershell
uv pip install -e .
```
### 第四步（可选）：安装 pngquant 图片优化工具
虽然是可选安装，但我超级建议你安装，因为ppt导出后，图片通常较大，不进行图片无损压缩，会导致文件大小过大。
如果你需要对导出的图片进行压缩优化，运行：
```powershell
.\install-pngquant.ps1
```
该脚本会：
1. 如果你已安装 scoop → 通过 scoop 安装 pngquant
2. 如果没有 scoop → 自动下载并安装到 `%APPDATA%\pngquant`，并添加到 PATH
安装完成后，**重新打开 PowerShell**，验证安装：
```powershell
pngquant --version
```
> 自定义安装目录：`.\install-pngquant.ps1 -InstallDir "D:\Tools\pngquant"`
> 强制重新安装：`.\install-pngquant.ps1 -Force`
### 第五步：开始使用
```powershell
# 导出 PPTX 为长图
pptopic export presentation.pptx
# 优化图片
pptopic optimize image.png
```
至此安装完成。如果任何步骤遇到问题，请参考下方详细说明。
## 安装
### 安装 uv
使用项目自带的安装脚本（推荐）：
```powershell
.\uv-installer.ps1
```
该脚本自动检测 uv 最新版本，支持国内 GitHub 加速镜像下载（`mirror.ghproxy.com`、`ghproxy.net`），并自动将 uv 添加到系统 PATH。
也可以通过 scoop 安装：
```bash
# 使用 scoop
scoop install uv
```
### 安装 pptopic
```bash
$ cd pptopic
$ uv pip install -e .
cd pptopic
uv sync
uv pip install -e .
```
## 使用

## 图片优化
为了获得最佳的图片压缩效果，推荐使用 [pngquant](https://pngquant.org/) 进行图片压缩。
当然，使用自己熟悉的图片优化压缩引擎是一样的。
### 自动安装脚本
使用提供的 PowerShell 脚本自动安装 pngquant：
使用提供的 PowerShell 脚本安装 pngquant：
```powershell
.\install-pngquant.ps1
```
该脚本会自动：
1. 检查 pngquant 是否已安装
2. 如果未安装，检查 scoop 是否已安装
3. 如果 scoop 未安装，自动安装 scoop
4. 使用 scoop 安装 pngquant
该脚本支持两种安装方式：
1. **已安装 scoop** → 通过 `scoop install pngquant` 安装
2. **未安装 scoop** → 从 pngquant 官网下载并安装到 `%APPDATA%\pngquant`，自动添加到 PATH
```powershell
# 自定义安装目录
.\install-pngquant.ps1 -InstallDir "D:\Tools\pngquant"
# 强制重新安装
.\install-pngquant.ps1 -Force
# 不修改 PATH
.\install-pngquant.ps1 -NoModifyPath
```
### 手动安装

This script auto-detects the latest uv release from GitHub and fetches an appropriate archive from
various download sources, then unpacks the binaries and installs them to the first of the following locations
