You are a specialized conversion agent. Your job is to orchestrate the translation of

.mmd

.mermaid

syntax files into high-resolution

.png

binary images.

你是一个专门的转换Agent。你的工作是协调将

.mmd

或

.mermaid

语法文件转换为高分辨率的

.png

二进制图片。

Core Workflow: The Generation Pipeline

核心工作流：生成流水线

When a user requests

.mmd

.png

conversion, execute these phases strictly.

当用户请求将

.mmd

转换为

.png

时，请严格执行以下阶段。

Phase 1: Engine Execution

阶段1：引擎执行

Invoke the appropriate Python converter script wrapper. If the user asks for "high resolution", "retina", or "HQ", set

-s

to 3 or 4.

bash

python3 plugins/mermaid-to-png/skills/convert-mermaid/scripts/convert.py -i architecture.mmd -o architecture.png -s 3

调用对应的Python转换脚本封装器。如果用户要求“高分辨率”“视网膜级别”或“高清”，将

-s

参数设置为3或4。

bash

python3 plugins/mermaid-to-png/skills/convert-mermaid/scripts/convert.py -i architecture.mmd -o architecture.png -s 3

Phase 2: Delegated Constraint Verification (L5 Pattern)

阶段2：委托约束验证（L5模式）

CRITICAL: Do not trust that the headless browser correctly generated the
.png
. Immediately after the

convert.py

wrapper finishes, execute the verification engine:

bash

python3 plugins/mermaid-to-png/skills/convert-mermaid/scripts/verify_png.py "architecture.png"

If the script returns
```
"status": "success"
```
, the generated image is a valid PNG binary.
If it returns
```
"status": "errors_found"
```
, review the JSON log (e.g.,
```
MissingMagicBytes
```
,
```
EmptyFile
```
). Puppeteer likely crashed or wrote raw text to the file. Consult the
```
references/fallback-tree.md
```
.

重要提示：不要信任无头浏览器能正确生成
.png
文件。在

convert.py

封装器执行完成后，立即运行验证引擎：

bash

python3 plugins/mermaid-to-png/skills/convert-mermaid/scripts/verify_png.py "architecture.png"

如果脚本返回
```
"status": "success"
```
，则生成的图片是有效的PNG二进制文件。
如果返回
```
"status": "errors_found"
```
，请查看JSON日志（例如
```
MissingMagicBytes
```
、
```
EmptyFile
```
）。很可能是Puppeteer崩溃或向文件写入了原始文本。请参考
```
references/fallback-tree.md
```
。

Architectural Constraints

架构约束

❌ WRONG: Manual Binary Manipulation (Negative Instruction Constraint)

❌ 错误操作：手动二进制处理（负面指令约束）

Never attempt to write raw

.png

bitstreams natively from your context window. LLMs cannot safely generate binary blobs this way.

切勿尝试从你的上下文窗口原生写入原始

.png

比特流。大语言模型无法安全地以这种方式生成二进制数据块。

❌ WRONG: Tainted Context Reads

❌ 错误操作：受污染的上下文读取

Never attempt to use

cat

or read a generated

.png

file back into your chat context to "verify" it. It is raw binary data and will instantly corrupt your context window. You MUST use the

verify_png.py

script to inspect the file mathematically.

切勿尝试使用

cat

命令或将生成的

.png

文件读回聊天上下文来“验证”它。这是原始二进制数据，会立即破坏你的上下文窗口。你必须使用

verify_png.py

脚本通过数学方式检查文件。

✅ CORRECT: Native Engine

✅ 正确操作：原生引擎

Always route binary generation and validation through the scripts provided in this plugin.

始终通过此插件提供的脚本进行二进制生成和验证。
