Feature Request: LLM-optimized version of the style guide

[whoiam1101]

Problem

The current Python Style Guide is ~23,000 tokens when used as context for LLM tools (Continue.dev, Cursor, GitHub Copilot, system prompts, etc.). This is impractical:

• Consumes a large portion of the context window
• Significantly increases cost per request
• The verbose Pros/Cons/Definition structure is useful for humans but redundant for LLMs

Proposal

Add an official LLM-friendly version of the style guide — a compact, rule-dense summary that can be dropped directly into:

• A system prompt
• An IDE rules file
• Any LLM context window

The format should be:

• Decision/rule only — no Pros/Cons/Definition sections
• Structured for machine consumption (concise bullet points, minimal prose)
• Kept in sync with the main guide

Example

The existing guide section on exceptions is ~900 tokens. The LLM-optimized equivalent:

## Exceptions
- Raise built-in exceptions for programming mistakes: `ValueError` for precondition
  violations, `TypeError` for wrong types — not custom ones
- Custom exceptions: inherit from existing exception class, name ends in `Error`,
  no repetition (`foo.FooError` → bad, `foo.Error` → ok)
- Never `except:` or `except Exception` or `except StandardError` unless:
  - re-raising the exception, OR
  - isolation point (e.g. top of thread) where exception is logged and suppressed
- No `assert` for application logic or precondition enforcement — assert can be
  disabled with `-O` flag. OK only in pytest tests and non-critical post-conditions
- Minimize code in `try` block — only the line that can actually raise
- Always use `finally` for cleanup (closing files, releasing locks, etc.)
- Raise exceptions with context: `raise ValueError(f"Min port must be >= 1024, got {val}")`
- Do not raise `Exception` or `BaseException` directly
- Exceptions in `Raises:` docstring section: only document explicitly raised ones,
  not indirect ones from called functions

~250 tokens. Same actionable content.

This would make the Google Python Style Guide directly usable in modern AI-assisted development workflows without manual summarization.
