Description

This skill takes raw, poorly indented code and returns a nicely formatted, readable version following community standard style guides. It supports multiple languages and provides clear error messages when language is not recognized or code is invalid.

Supported Languages & Style Rules

• Python: PEP 8 – 4 spaces per indentation level; no unnecessary blank lines; single quotes preferred.
• JavaScript (JS): 2 spaces per level; semicolons optional but consistent; { on same line.
• TypeScript (TS): same as JavaScript, plus explicit return types for functions when possible.
• JSON: 2 spaces; no trailing commas; no comments; keys in double quotes.
• HTML: 2 spaces per level; inline elements should not be broken across lines; self-closing tags for void elements.
• CSS: 2 spaces; one selector per line; opening brace on same line; space after colon.
• Go: use gofmt style – tabs for indentation (width 8); no extra spaces; consistent formatting.

Instructions

When the user provides a code snippet and specifies (or implies) a language:

1. Detect or ask for language if not provided. Supported: python, javascript, typescript, json, html, css, go.
2. Check for syntax errors – if the code is clearly invalid (e.g., unmatched braces, missing quotes), inform the user and suggest correction before formatting.

3. Apply the corresponding style rules from above.
4. Output the formatted code inside a Markdown code block with the correct language identifier.
5. Add a brief explanation of what changes were made (e.g., "Added 2-space indentation and fixed spacing after commas").

If the language is not supported, respond with: "Sorry, I don't support formatting for {language} yet. Supported languages: python, javascript, typescript, json, html, css, go."

Examples

Example 1: Python

User: "Format this Python: def hello():print('world')" AI: ```python def hello(): print('world')

這個Skill質量中等偏上，能有效格式化多種常見程式語言的程式碼，風格規則定義清晰專業。它擅長處理結構化的格式化需求，但對於複雜程式碼的容錯能力有限。優點是支援語言豐富、規則明確；不足是文件示例不完整、缺乏靈活配置，且版本資訊存在不一致，可能會給使用帶來困惑。
