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
gofmtstyle – tabs for indentation (width 8); no extra spaces; consistent formatting.
Instructions
When the user provides a code snippet and specifies (or implies) a language:
- Detect or ask for language if not provided. Supported: python, javascript, typescript, json, html, css, go.
- Check for syntax errors – if the code is clearly invalid (e.g., unmatched braces, missing quotes), inform the user and suggest correction before formatting.
- Apply the corresponding style rules from above.
- Output the formatted code inside a Markdown code block with the correct language identifier.
- 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:
def hello():
print('world')
