Syntax & Style

Quotes: Enforce Double Quotes (") over Single Quotes ('). Good: x += "." Bad: x += '.' SQL: Always use Multi-line strings (""") for SQL queries. Templates: Set language mode to jinja-html. Spacing: Keep vertical spacing compact (no excessive blank lines). Readability: Prioritize Readable Code over "clever"/compact [pythonic] one-liners.

Comments

Preserve comments: Do NOT delete existing, still relevant comments. Comment liberally: Explain why, not just what.

Logic & Operations

File Collisions: If a file exists, append _[timestamp] to the new filename. Simplicity: Choose the simplest working solution.

Tooling Preference (Web)

Primary: browser_action (ALWAYS try this first). Fallback: Other browser tools (Only if browser_action fails).
